Daqing Container House Installation

The installation of container houses in Daqing City requires selecting the appropriate process based on the type, with a particular focus on climate and corrosion resistance issues. It can be divided into two categories: container house engineering and packed box-type container house installations, with their respective installation processes and precautions as follows:

I. Installation Process for Container House Engineering

1. Factory Modification and Processing
   Based on standard shipping containers, operations such as cutting openings, internal reinforcement, and laying water and electricity pipeline channels are carried out in the factory according to design drawings. Special attention should be paid to thermal insulation and rust prevention: rock wool or polyurethane foam insulation layers are installed inside the container, and anti-rust paint is sprayed on the surface of the steel structure to ensure building functionality and safety.
2. On-site Installation and Module Connection
   After transportation to the site, lifting equipment is used to position and install the modules. High-strength bolts or welding are used to fix the connectors between modules, ensuring structural uniformity. Subsequently, water and electricity pipelines are connected, module gaps are sealed, and external components such as awnings and stairs are installed.
3. Interior Decoration and System Integration
   After completing the main structure, interior wall panels, floors, and ceilings are laid, and lighting fixtures and sanitary ware are installed. Electrical, water supply and drainage, heating (which requires special consideration in Daqing), and ventilation systems are integrated to ensure a comfortable indoor environment.

II. Installation Process for Packed Box-Type Container Houses

1. Demand Design and Factory Production
   Determine the size and layout based on the purpose, number of occupants, and functional zoning, and design the positions of doors and windows as well as electrical circuits. In the factory, steel structure welding, wall panel compositing, door and window installation, and preliminary decoration are completed, with some houses having pre-installed pipelines.
2. Transportation and On-site Foundation Treatment
   Modular components are classified and packed before being transported to the site. The foundation is treated according to geological conditions: the soil is leveled and compacted, and a concrete foundation is laid or pile foundations are set to prevent structural deformation caused by frost heave or settlement.
3. Module Installation and Final Work
   Lifting equipment is used to position the frame and wall panel modules, which are connected with fasteners. Finally, joint sealing and roof waterproofing are carried out, and internal wiring and installation of lighting fixtures and sanitary ware are completed.

III. Specific Considerations for Installation in Daqing

1. Climate Adaptability
   Due to the cold winters, the thermal insulation layer needs to be thickened (e.g., rock wool ≥ 100mm), double-glazed windows should be used, and additional insulation panels can be attached to the exterior walls. The structural design should be able to withstand snow loads (according to local specifications) to prevent the roof from collapsing under accumulated snow.
2. Corrosion Resistance Treatment
   In response to the industrial environment and the risk of corrosion from de-icing agents, the steel structure of the container should be treated with hot-dip galvanizing or epoxy zinc-rich primer, and exposed parts should be regularly painted with anti-rust paint. The drainage system should be designed with a slope to prevent water accumulation from accelerating corrosion.

By following standardized processes and taking targeted measures, container houses can be ensured to be safe, durable, and energy-efficient in the Daqing area.
