In recent years, with the concept of sustainable development deeply rooted in the hearts of the people, the construction industry has gradually transformed in the direction of green environmental protection. In this context, prefabricated houses have become a model of environmental protection in the construction industry due to their outstanding performance in resource conservation, pollution reduction and carbon emission control.
1. Analysis of the environmental protection advantages of prefabricated houses
(1). Production stage: reduce material waste
In traditional building construction, a lot of material is often wasted due to manual operation and on-site cutting. The components of the prefabricated house are precisely produced in the factory, and the utilization rate of raw materials is greatly improved, which greatly reduces waste. In addition, factory production allows for better control over the type and quality of materials, thus avoiding unnecessary material loss.

Through the data, it can be seen that the material utilization rate of prefabricated houses is as high as more than 90%, much higher than the 70%-80% of traditional buildings, and the amount of construction waste generated has also been reduced by about 70%. In addition, prefabricated houses are more inclined to recyclable and low-carbon materials in their material selection, further enhancing their eco-friendly attributes.
(2). Construction phase: reduce on-site pollution
Traditional construction sites are often accompanied by noise, dust and construction waste, which have a negative impact on the surrounding environment. Prefab houses, on the other hand, are modular for a cleaner and more efficient construction process. This prefabricated construction method not only reduces the disturbance to the surrounding residents, but also effectively controls the emission of pollutants during the construction process.

Xinjiang has a vast territory, rich resource development and vigorous infrastructure construction, attracting a large number of builders. However, many construction sites are located in remote Gobi deserts, deserts or deep mountains, which makes it difficult to quickly meet the surging demand for accommodation due to the inconvenience of traditional building materials and the long construction period. The dormitory detachable container house project came into being, which perfectly fits the special geographical environment and construction rhythm of Xinjiang by virtue of the characteristics of industrial production and rapid assembly.
Detachable container house design: both safety and comfort
These dormitories were designed with the extreme weather conditions of Xinjiang in mind. The main body is made of high-strength steel frame, which is strong and durable, enough to withstand frequent windy weather, even if the wind is howling, the prefab house is as stable as Mount Tai. The wall is made of high-quality thermal insulation panels, filled with dense thermal insulation materials, and the cold wind in winter is firmly blocked outside, and the indoor warmth is harmonious; Under the scorching sun of summer, it can effectively block the heat and keep it cool.
Although the interior layout of each dormitory is compact but warm, although the area is limited, it is cleverly placed with beds, tables and chairs, wardrobes and other necessary facilities for life, the beds are soft and comfortable, and the wardrobe capacity is sufficient, providing plenty of rest space for builders who are tired after a long day. Independent windows allow sunlight to pour in generously, dispel the haze, and allow residents to enjoy the magnificent natural scenery of Xinjiang at any time. The toilet is separated from wet and dry, equipped with water-saving sanitary ware, and efficient use is achieved in Xinjiang, where water resources are relatively precious.
Quick to build: Efficient "magical" puzzle pieces
The biggest attraction of dormitory prefabricated house is their amazing speed of construction. In the prefabrication process, the individual parts are precisely produced like precise puzzle pieces, from the walls and floors . After being transported to the project site in Xinjiang, a large crane and a professional construction team quickly put in place, like building blocks, splicing the box room piece by piece. In just a few days, rows of neat and brand-new dormitory boxes have risen from the ground, racing against time, immediately providing a shelter for the builders, so that the project period will not be delayed due to accommodation problems.
Environmental protection and energy saving: protect the environment of Xinjiang
At a time when environmental awareness is deeply rooted in the hearts of the people, the dormitory portable house project can be called a green model. In the construction process, compared with traditional buildings, the generation of construction waste is greatly reduced, and the waste materials are almost negligible. In the use stage of the container house, the excellent thermal insulation performance reduces energy consumption, and the heating and cooling equipment does not need to run with high power, which not only saves electricity costs, but also reduces carbon emissions. Moreover, when the project is completed, the box house can be disassembled and reorganized and transported to a new location for recycling, minimizing the environmental impact on the pure land of Xinjiang.
Diversity and integration: a new place for cultural exchange
Xinjiang is a multi-ethnic settlement, and the dormitory container house has also become a miniature world for the exchange and integration of compatriots of different ethnic groups. In their spare time, builders from all over the world gathered in the container dormitory area, and the dormitory container house carries not only a residential function, but also a warm bond of ethnic unity, so that multiculturalism can coexist and prosper in the wave of construction in Xinjiang.
The Xinjiang dormitory container house project is writing a new chapter of housing security for this land full of opportunities with innovative and pragmatic actions, which is a temporary residence and a solid cornerstone for cohesion and development.
Preparation and planning: precise anchoring, according to local conditions
At the beginning of the project, the team took root in various parts of Yunnan to conduct research. Knowing that Yunnan's terrain is undulating and the climate is diverse, and the construction of traditional buildings is difficult, the characteristics of DXH modular and prefabricated container houses have become the key to solving the problem. Environmentally friendly and durable materials such as light steel and rock wool sandwich panels are selected to lay a solid foundation for subsequent efficient construction and safe living, and each step of the planning accurately responds to the local residential demands of Yunnan.
Efficient construction: quick solutions, quality and quantity
In the prefabrication stage of the factory, the automated production line is in full swing. The high-precision cutting equipment controls the size error of light steel components within millimeters, and the production of sandwich panels is smooth, and the prefabricated part is completed in just over a month. Transported to the project site in Yunnan, the assembly is as neat as building blocks. Compared with the traditional brick-concrete house, there is no need to wait for a long time for concrete to solidify, brickwork and wall repair, large cranes and professional workers can complete the construction of multiple sets of houses per day, and the progress is not slowed down in the complex mountain environment, and the construction period is greatly reduced by nearly half.
Stable and safe: Rock solid and worry-free
Yunnan is occasionally plagued by earthquakes and strong winds, and the advantages of DXH prefabricated houses are fully demonstrated. The light steel frame has sufficient toughness and high strength, and can resolve the impact of earthquakes through professional structural design; The sandwich panel of the wall is filled with rock wool, and the fire resistance reaches the A-level standard, which can buy valuable time for residents to escape in case of fire, and can also resist the pull of strong winds.
Eco-friendly and livable: green accompaniment, comfortable and free
The construction process is environmentally friendly. Factory prefabrication reduces on-site construction waste, reducing waste by more than 80% compared to traditional buildings. After moving in, the insulated sandwich panels make the interior warm in winter and cool in summer, reduce the energy consumption of air conditioning by 30% to 50%, reduce the cost of residents, and also fit the pursuit of low-carbon life in Yunnan. The interior space of the house is flexible and changeable, and the layout can be easily adjusted as the family grows and living habits change.
From preparation to completion, this detachable container house community project in Yunnan has carved an ideal home under complex geographical conditions by virtue of the all-round advantages of detachable container house, which is not only a new starting point for the life of the people of Yunnan, but also provides a valuable blueprint for the mountain urban residential project, leading the innovation direction of the future living model.
In the field of modern construction and engineering, prefabricated components are increasingly used. Prefabricated components can not only improve construction efficiency, but also ensure project quality. However, prefabricated components often face corrosion problems during use, especially in harsh environmental conditions. In order to solve this problem, galvanizing is widely used in the anti-corrosion treatment of prefabricated components.
What is galvanizing?
Galvanizing is a process that prevents corrosion by covering the metal surface with a layer of zinc. Zinc, as an active metal, can undergo oxidation reaction before iron or steel, thereby protecting the substrate from corrosion. There are two main types of galvanizing processes: hot-dip galvanizing and electro-galvanizing.
1. Hot-dip galvanizing: The prefabricated component is immersed in molten zinc liquid to form a layer of zinc-iron alloy and pure zinc on its surface. This process is suitable for large components and can provide a thicker zinc layer with excellent anti-corrosion properties.
2. Electro-galvanizing: A layer of zinc is deposited on the surface of the prefabricated component through electrolysis. This process is suitable for small components or occasions where a thinner zinc layer is required, and has a better surface finish.
Engineering steps for galvanizing prefabricated components
1. Surface treatment: This is the most critical step in the galvanizing process. The prefabricated components need to be thoroughly cleaned before galvanizing to remove oil, rust and other impurities. Common surface treatment methods include sandblasting, pickling, etc.
2. Coating treatment: After surface cleaning, the prefabricated components need to be treated with coating agents. Coating agents are usually a mixed solution of ammonium chloride and zinc chloride, which can prevent the components from oxidizing before being immersed in the zinc liquid.
3. Hot-dip galvanizing: The prefabricated components that have been surface treated and coated with coating agents are immersed in molten zinc liquid for a certain period of time to allow the zinc liquid to fully react with the substrate to form a zinc-iron alloy layer and a pure zinc layer.
4. Cooling: After galvanizing, the prefabricated components need to be removed from the zinc liquid and cooled. The cooling method can be natural cooling or water cooling, depending on the process requirements.
5. Post-processing: After cooling, the prefabricated components may need some post-processing, such as removing excess zinc slag, trimming the surface, etc., to ensure the appearance and quality of the components.
The significant role of galvanizing on prefabricated components
1. Anti-corrosion protection: The galvanized layer can effectively isolate the contact between the prefabricated components and the external environment, preventing the corrosion of the substrate by oxygen and moisture. When the zinc layer is damaged, it can continue to protect the substrate through sacrificial anodes, extending the service life of the components.
2. Improve durability: The galvanized layer has excellent wear resistance and impact resistance, can effectively resist external physical damage, and improve the durability of prefabricated components.
3. Reduce maintenance costs: Due to the long-term anti-corrosion effect of the galvanized layer, prefabricated components do not need frequent anti-corrosion maintenance during use, which greatly reduces maintenance costs.
4. Aesthetics: The galvanized layer has a silvery-white luster, which can improve the appearance quality of prefabricated components and is suitable for occasions with high aesthetic requirements.
5. Environmental protection: The zinc used in the galvanizing process is a recyclable material that meets environmental protection requirements. In addition, the galvanized layer does not release harmful substances during use and is environmentally friendly.
In the modern construction industry, precast concrete has gradually become the preferred material for many construction projects due to its high efficiency, environmental protection and high quality. However, although precast concrete has high strength and durability when it leaves the factory, proper maintenance is still the key to ensure its long-term performance.
What is precast concrete?
Precast concrete refers to concrete components that are prefabricated in factories or prefabrication yards, such as wall panels, beams, columns, stairs, etc. These components are produced in factories with strict quality control and then transported to the construction site for assembly. Compared with traditional cast-in-place concrete, precast concrete has the following advantages:
1. Quality control: The factory production environment ensures that the concrete proportioning, pouring and curing process are more precise, reducing the uncertainty in on-site construction.
2. Construction efficiency: Precast components can be quickly installed on the construction site, greatly shortening the construction period.
3. Environmental protection: Precast concrete reduces waste and pollution in on-site construction and meets the requirements of green buildings.
4. Design flexibility: Precast concrete can produce components of various shapes and sizes according to design requirements to meet diverse construction needs.
Maintenance methods for precast concrete
Although precast concrete has undergone strict curing and quality control when it leaves the factory, it still needs proper maintenance during its use to ensure its long-term performance and durability. The following are several key steps for precast concrete maintenance:
1. Regular inspection
Regular inspection is the basis for maintaining precast concrete structures. Inspection contents include:
- Surface cracks: Cracks are one of the most common problems in concrete structures. Although small cracks may not immediately affect structural safety, if not treated in time, moisture and chemicals may penetrate into the cracks, causing steel corrosion and concrete spalling.
- Steel corrosion: Steel corrosion is one of the main causes of aging of concrete structures. Through regular inspections, steel corrosion problems can be discovered and dealt with in time to prevent structural strength from decreasing.
- Surface wear: Precast concrete components may be subject to wear during use, especially in high-traffic areas. Regular inspections can detect wear problems in time and take repair measures.
2. Cleaning and surface treatment
Surface cleaning of precast concrete is an important part of maintenance work. The accumulation of dust, dirt and chemicals not only affects the beauty of the building, but may also cause corrosion to the concrete surface. Regular cleaning can use high-pressure water guns or appropriate detergents to ensure that the concrete surface remains clean. In addition, surface treatment such as the application of sealants can effectively prevent the penetration of moisture and chemicals and extend the service life of concrete.
3. Crack repair
Cracks are an inevitable problem in concrete structures, but timely repair can prevent them from further expansion. For small cracks, materials such as epoxy resin or polyurethane can be used to fill them. For larger cracks, more complex repair techniques may be required, such as injecting grouting materials or performing local reinforcement.
4. Waterproofing
Moisture is one of the biggest enemies of concrete structures. Precast concrete components exposed to humid environments for a long time are prone to freeze-thaw damage, steel bar corrosion and other problems. Therefore, waterproofing is an important part of maintenance work that cannot be ignored. Water penetration can be effectively prevented by applying waterproof coatings and installing waterproof membranes.
5. Anti-corrosion protection
In some special environments, such as coastal areas or near chemical plants, precast concrete structures may be corroded by salt spray, chemicals, etc. In this case, corrosion protection is particularly important. The corrosion resistance of the structure can be enhanced by applying anti-corrosion coatings or using corrosion-resistant concrete additives.
The significant impact of maintaining precast concrete
Proper maintenance can not only extend the service life of precast concrete structures, but also bring significant impacts in the following aspects:
1. Improve structural safety
The safety of precast concrete structures is directly related to the overall stability of the building. Through regular maintenance, potential structural problems can be discovered and repaired in time, structural failures caused by cracks, rust and other problems can be prevented, and the safe use of the building can be ensured.
2. Reduce maintenance costs
Although maintenance work requires a certain amount of investment, the cost of regular maintenance is much lower than large-scale repairs or reconstruction after structural damage. Through preventive maintenance, future maintenance costs can be effectively reduced and the long-term operating costs of buildings can be reduced.
3. Extend the life of the building
The design life of precast concrete structures is usually more than 50 years, but without proper maintenance, their actual service life may be greatly shortened. Through regular maintenance, it can be ensured that precast concrete structures maintain good performance for decades and extend the overall life of the building.
4. Maintain the beauty of the building
The appearance of precast concrete structures is also an important part of the value of the building. Through regular cleaning and surface treatment, the concrete surface can be kept smooth and beautiful, enhancing the overall image of the building.
5. Environmental benefits
Precast concrete itself is an environmentally friendly building material. By extending its service life through maintenance, it can reduce the generation of construction waste, reduce resource consumption, and further reduce the impact on the environment.
In the field of modern construction, precast concrete is gradually becoming a revolutionary building material. It not only improves construction efficiency, but also significantly improves building quality. With the continuous advancement of process technology and the application of high-tech equipment such as Precast Concrete Magnet, the future development prospects of precast concrete will be even broader. Whether it is residential buildings, public buildings or infrastructure, precast concrete will play an important role and promote the construction industry to a higher level.

The construction industry continues to evolve, incorporating innovative technologies to improve efficiency, safety, and precision. Among these advancements, lifting systems for precast concrete units stand out as a game-changer, revolutionizing the way we handle and install precast concrete elements. As construction practices continue to evolve, lifting systems will undoubtedly play an important role.
First, demystifying the lifting system: the key components and what they do
The lifting system for precast concrete units is an elaborate assembly designed to safely and efficiently lift, manipulate, and position precast concrete elements during construction. Let’s break down its basic components and their functions:
Lifting anchors: These are the workhorses of the system and are embedded into the precast concrete units when they are cast. They provide a secure connection point for the lifting equipment, ensuring a reliable connection between the unit and the lifting mechanism. There are several types of lifting anchors, including ring anchors, threaded inserts, and lifting plates, each of which is suitable for specific load capacities and concrete element configurations.
Lifting equipment: This category includes the machinery responsible for the actual lifting and moving of the precast units. Common examples include:
Crane: Tower cranes, mobile cranes, and overhead cranes are widely used for their versatility and ability to handle heavy loads at different heights and distances.
Vacuum lifters: They utilize suction cups to create a vacuum seal on the concrete surface, providing a non-intrusive lifting solution for fine or polished finishes.
Paver beams: These horizontal beams distribute the lifting load evenly across multiple lifting points, preventing stress concentrations and ensuring stability of the precast unit during lifting.
Rigging accessories: This includes a range of components that connect the lifting anchor to the lifting equipment, such as:
Slings: Slings are made of wire rope, chain or synthetic materials and provide flexibility and adjustability in lifting configurations.
Shackles: These U-shaped connectors secure the slings to the lifting anchors and other rigging components.
Turnbuckles: Used to adjust the length and tension of the slings, ensuring load distribution and alignment during lifting.
Secondly, the adoption of lifting systems for precast concrete units has brought a paradigm shift to the concrete industry, bringing multiple benefits:
Enhanced safety: By providing a safe and controllable lifting mechanism, these systems significantly reduce the risk of accidents and injuries associated with manually handling heavy precast elements.
Increased efficiency: The streamlined lifting process minimizes downtime and maximizes productivity on the construction site, thereby reducing project completion time.

The world of applications: where lifting systems shine
The versatility of precast concrete unit lifting systems makes them an integral part of a wide range of construction projects:
High-rise buildings: Facilitates the efficient installation of precast wall panels, columns, beams and floor slabs in high-rise buildings.
Bridges and infrastructure: Enables precise placement of precast beams, abutments and other structural components in bridge construction and infrastructure projects.
Industrial facilities: Supports the construction of warehouses, factories and other industrial buildings with precast concrete elements.
Residential buildings: Simplifies the installation of precast walls, floors and stairs in residential buildings, from single-family homes to apartment complexes.
U-shaped magnetic formwork profileis a combination system of integrated magnetic block system, key holder and long steel frame channel. It is widely used in precast concrete wall panel production. After lowering the formwork, the formwork profile on the marking integrated magnet is activated and locked. The integrated magnet presses the formwork profile precisely on the formwork.
By integrating high-performance magnets in the U-shaped steel frame, the formwork can be quickly fixed and removed. The magnets can be activated or released by simple manual or foot operations without the need for complex mechanical devices. It significantly improves construction efficiency and reduces the time and labor costs of formwork installation and removal. Its magnetic tension mechanism ensures that the formwork remains stable during concrete pouring and avoids displacement. At the same time, it can achieve precise edge management, avoid measurement errors in traditional formwork construction, and ensure the dimensional accuracy and appearance quality of prefabricated components. The magnetic formwork system is made of high-performance NdFeB magnets and thick steel plates, which can withstand harsh construction environments, have a long service life, and low maintenance costs.
Compared with traditional formwork, the U-shaped magnetic formwork system has many significant advantages, which are mainly reflected in the following points:
Higher construction efficiency-the U-shaped magnetic formwork system uses magnetic force to quickly fix and remove the formwork, which is easy and quick to operate and does not require complex mechanical movements. Compared with traditional formwork, its installation and removal time is greatly shortened, which can significantly improve construction efficiency. The mold replacement time can be saved by more than 90%, which is particularly suitable for the "small batch, multiple batch" production mode.
Uniform force and improved quality-the clamping force of the magnetic formwork is evenly distributed on the entire contact surface, and the mold back plate is evenly stressed, avoiding the deformation of the traditional formwork due to uneven local force. This not only improves the appearance quality and dimensional accuracy of the prefabricated components, but also extends the service life of the mold.
Easy to operate and high safety-the U-shaped magnetic formwork system is easy to operate and can be quickly mastered without professional skills. There are no moving parts inside, no complex mechanical devices are required, and the safety hazards caused by mechanical failures are reduced.
The system is also equipped with a variety of safety detection devices, such as magnetic flux detection systems and progressive sensors, which can monitor the working status in real time to ensure construction safety.
Strong durability and low maintenance cost - Since the magnetic template uses permanent magnetic materials, there are no moving parts inside, the service life is long and almost maintenance-free. Compared with the traditional hydraulic platen system, its maintenance cost and downtime are greatly reduced.
Environmental protection and energy saving - The U-shaped magnetic template system does not require continuous power supply during operation, and only uses electricity briefly when loading and unloading molds. Compared with traditional hydraulic systems, it consumes less energy and does not cause pollution such as hydraulic oil leakage.
Strong applicability and high flexibility - The magnetic template system can adapt to molds of different shapes and sizes without the need for standardized modification of the mold backing plate. It is easy to install and does not require additional modifications to the injection molding machine or construction equipment.
Reduce waste and optimize production - The ability to quickly change molds reduces equipment downtime and maintains stable temperatures during production, thereby reducing waste caused by downtime.
In modern construction projects, the production efficiency and quality of precast panels and double wall panels directly affect the progress and cost of the project.
