Installation of Container Houses in Hegang City

The installation of container houses in Hegang City requires a rigorous process, covering multiple stages from site preparation and structural construction to functional completion. The specific steps are as follows:

I. Site and Foundation Preparation

1. Site Selection: Ensure the site is flat, dry, and well-drained, avoiding low-lying or waterlogged areas. Clear the site of debris, garbage, and sharp objects to prevent damage to the container bottom.
2. Foundation Construction: Choose the foundation type based on geological conditions and container weight. Common options include:
   • Steel Foundation: Suitable for soft soil, dispersing pressure through steel frames;
   • Concrete Foundation: Provides high stability, requiring pre-pouring and curing;
   • Wooden Foundation: Suitable for temporary structures, cost-effective but requiring moisture-proof treatment.
     Foundation construction must strictly follow design drawings, ensuring a horizontal error of no more than 5 millimeters to prevent subsequent installation tilt.

II. Structural Construction and Container Installation

1. Frame Assembly:
   • Secure steel columns to foundation embedments using high-strength bolts, ensuring verticality;
   • Install crossbeams and diagonal braces to form a stable triangular structure, enhancing wind resistance.
2. Container Positioning:
   • Use a crane to lift pre-processed (e.g., cut windows and doors, reinforced corner fittings) containers onto the frame;
   • Adjust the position using a laser level to ensure uniform gaps between containers (usually ≤10 millimeters);
   • Connect adjacent containers through welding or bolting, focusing on reinforcing corner nodes.

III. Functional System Integration

1. Enclosure System Installation:
   • Lay waterproof membranes or metal sheets on the roof with a slope of ≥5% for drainage;
   • Install thermal insulation and decorative integrated panels on exterior walls, sealing joints with adhesive;
   • Use thermal-break aluminum alloy for doors and windows, equipped with double-glazed units to enhance sound and thermal insulation.
2. Internal System Construction:
   • Pipeline Installation: Run electrical wires through PVC pipes along corners, and reserve slopes for water supply and drainage pipes;
   • Thermal Insulation: Fill walls with rock wool or polystyrene boards, and lay XPS extruded polystyrene boards on the floor;
   • Decoration: Use eco-friendly bamboo fiber panels for walls and choose anti-slip tiles or composite flooring for the floor.

IV. Inspection and Handover

1. Structural Safety Inspection: Check welding points, bolt tightness, and overall verticality;
2. Functional Testing: Simulate heavy rain to test the drainage system, and power on to test lighting and smart devices;
3. Environmental Inspection: Confirm that the fire rating of thermal insulation materials reaches B1 level and that indoor formaldehyde content is ≤0.08mg/m³.

Installation Characteristics in Hegang: Emphasis on winter thermal insulation, with exterior wall insulation layers typically ≥80mm thick; modular design shortens construction time, with completion from foundation to handover in just 15-20 days; offers personalized customization services, such as solar power systems and integrated floor heating, to meet extreme cold climate needs.
