Daqing Container House Construction

The construction of container houses in Daqing requires comprehensive consideration of technical characteristics, climate adaptability, and economic efficiency, among other factors.

Basic Construction Process and Technical Characteristics of Container Houses

Container houses use standard shipping containers as basic units, achieving flexible spatial combinations through modular design. The construction process is divided into two stages: factory processing and on-site installation. In the factory, cutting openings, internal reinforcement, laying water and electricity pipelines, and thermal insulation and rust prevention treatments are completed. On-site, positioning and installation are carried out using lifting equipment, with high-strength connectors used to secure the modules, followed by pipeline connections, gap sealing, and installation of external components. The technical advantages include a short construction period (with a high proportion of factory prefabrication), recyclable materials, flexible layout, and controllable costs.

Specific Considerations for Construction in the Daqing Area

1. Climate Adaptability
   Daqing experiences long and cold winters, necessitating a focus on enhancing thermal insulation performance. Rock wool or polyurethane foam insulation layers are installed inside the container bodies, double-glazed windows are used, and external wall insulation panels are added to reduce heating energy consumption. The structure must withstand snow loads, and the load-bearing capacity of the steel frame must be verified during design.
2. Foundation Treatment
   Depending on the geological conditions, options such as leveling and compaction, concrete foundations, or pile foundations are selected to prevent structural deformation caused by frost heave. For example, pile foundations are used to disperse loads on soft soil foundations, and settlement space is reserved in seasonally frozen soil areas.
3. Corrosion Prevention Treatment
   In response to the industrial environment and the risk of corrosion from de-icing agents, the container body surface undergoes hot-dip galvanizing treatment, welding areas are painted with anti-rust paint, and regular inspections and maintenance are carried out.

Advantages of Packing-Box Houses on Construction Sites in Daqing

Packing-box houses, as an improved form of container houses, have the following characteristics:

• High Installation Efficiency: The main structure is prefabricated in the factory, and only foundation treatment and lifting connections are required on-site. Medium-sized projects can be completed within a few weeks, reducing the construction period by more than 50% compared to traditional prefabricated temporary buildings.
• Strong Structural Performance: The steel frame structure offers excellent earthquake and wind resistance. The overall rigidity is high after the combination of independent container bodies, enabling resistance to earthquakes of magnitude 8 and typhoons of category 12.
• Excellent Thermal Insulation Performance: The walls are filled with rock wool or glass wool, with a heat transfer coefficient below 0.5W/(m²·K), meeting the energy-saving requirements of the severely cold region in Daqing.
• Economic Efficiency and Environmental Protection: Although the initial cost is higher than that of prefabricated temporary buildings, they can be reused more than 10 times, reducing long-term costs by 30%. The steel structure has a recycling rate of 90%, and construction waste is reduced by 60%.

During construction, it is essential to strictly follow regulations to ensure the strength of module connection nodes, pipeline sealing, and fire resistance ratings, thereby achieving safe, efficient, and sustainable construction goals.
