Heihe Container House Construction

The construction of container houses in Heihe City requires comprehensive consideration of the construction process, material suitability, environmental adaptability, and key construction points, as detailed below:

I. Construction Process

1. Site Selection and Foundation Construction
   • The site must be level and well-drained to prevent water accumulation or frost heave from affecting stability.
   • The foundation uses concrete or steel frame structures to ensure load-bearing capacity. In Heihe, where the winter frost depth is significant, the foundation requires special treatment, such as setting up an elevated layer and adding insulation to prevent frost heave from damaging the foundation.
2. Container Installation
   • Use lifting equipment to position prefabricated container modules onto the foundation, securing them with bolts or welding to ensure structural stability.
   • Seal the gaps between modules to prevent cold air infiltration.
3. Interior Renovation
   • Thermal Insulation Layer: Use low thermal conductivity materials like rock wool or polystyrene board to reduce heat loss.
   • Electrical and Plumbing: Pre-embed wiring and pipes that meet frost-resistant standards (e.g., pipes wrapped with insulation).
   • Flooring: Choose wear-resistant and slip-resistant materials (e.g., anti-slip tiles or epoxy flooring) suitable for snowy environments.
   • Roof: Adopt a double-layer structure with an outer waterproof layer, an inner insulation layer, and optional insulation material in between.

II. Material Selection

1. Container Body: The steel must undergo anti-rust treatment (e.g., spraying with anti-corrosion paint) to extend its service life.
2. Insulation Materials: Prioritize rock wool or polystyrene board for their balance of insulation and fire resistance.
3. Doors and Windows: Use multi-layer vacuum or argon-filled Low-E glass windows with thermal break aluminum alloy or wooden composite frames to reduce thermal bridging and improve airtightness.
4. Exterior Coating: Must be corrosion-resistant and weather-resistant to withstand Heihe's humid climate.

III. Environmental Adaptability Design

1. Thermal Insulation: Add an insulation layer to the exterior walls of the container to maintain indoor temperatures within a comfortable range (e.g., 18-22°C).
2. Frost Protection Measures: Install insulation at the foundation base to prevent frost from affecting building stability; ensure water pipes are buried deeper than the frost line or use electric tracing technology.
3. Weather Resistance: The exterior coating must resist low temperatures and snow erosion, ensuring no cracking or peeling over long-term use.

IV. Construction Advantages and Precautions

1. Advantages: Modular design allows for rapid combination and expansion, with factory prefabrication reducing on-site construction time, making it suitable for Heihe's short construction season.
2. Precautions:
   • Winter construction requires insulation measures (e.g., temporary heating equipment) to ensure concrete curing quality.
   • The door and window systems must be tightly sealed to prevent cold air infiltration and increased energy consumption.
   • Regularly inspect the foundation insulation layer to prevent settlement caused by frost thawing.
