Rural Container House Installation

When installing container houses in rural areas, it is essential to focus on structural safety, foundation treatment, installation procedures, and reinforcement measures, while also complying with local approval requirements.

1. Site Selection and Foundation Requirements

1. Site Selection Standards
   Avoid hazardous areas such as high-voltage power lines, cliffs, riverbanks, and strong wind zones. Ensure a safe distance from operational and residential areas. For example, a construction site in Shanxi placed container houses in a flat area away from high-voltage lines to avoid safety hazards.

2. Foundation Treatment
   Choose brick or concrete foundations based on geological conditions, ensuring foundation flatness error does not exceed ±25mm and wall height deviation ≤10mm. For example, the Xinjiang Dashixia Dam project used concrete piers to reinforce the foundation, enhancing overall stability. For long-term outdoor use, pre-embed drainage pipes to prevent structural corrosion from water accumulation.

2. Installation Procedures and Material Selection

1. Main Structure Installation

   • Frame Assembly: Prefer fully steel structural frames (e.g., Suzhou Zhongnan packing boxes), which can withstand wind speeds up to 12 and earthquakes up to magnitude 8, with a deformation rate of only 0.18%.
   • Wall and Roof Panel Installation: When using color-steel sandwich panels, ensure the steel plate thickness meets standards (e.g., ≥0.5mm for white-top white-box types) to avoid deformation due to thin materials. For example, a project in Nanchang, Jiangxi, experienced wall cracking after three years due to the use of inferior sandwich panels.
   • Floor Installation: Use magnesium oxide board as the base material. When laying along a 6-meter direction, cut corners to align, and secure joints with cross-head flat燕尾丝 (cross-head flat-tail screws) at intervals of 300-350mm.

2. Key Node Treatment

   • Concealed Works: Protect water and electricity lines with pipes, use SBS modified bitumen membranes for the damp-proof layer, and conduct a 48-hour closed water test after applying the waterproof layer.
   • Window and Door Sealing: Fill gaps between window frames and wall panels with expanding foam, and apply weather-resistant sealant along the outer edges to prevent rainwater leakage.

3. Reinforcement and Disaster Prevention Measures

1. Wind Resistance Reinforcement
   Add 40×40 wind-resistant columns on balconies, weld them with 30×30 angle irons between columns, and secure roof panels with 125mm self-tapping screws. For example, a project in Khabarovsk, Russia, withstood strong local winds through such reinforcement.

2. Seismic Design
   Use high-strength bolts to fasten frame connections, ensuring steel beam verticality deviation ≤H/1000 (H is the beam height). The Suzhou Zhongnan team completed the delivery of 1,000 earthquake-resistant (magnitude 8) houses in three months for the Qatar World Cup project using a "factory prefabrication + on-site rapid assembly" model.

3. Snow Load Prevention
   Add 40×60 square tube crossbeams in the middle of the roof to distribute snow pressure. For example, a project in Heilongjiang avoided roof collapse from winter snow accumulation through this design.

4. Approval and Compliance

Self-built container houses in rural areas require construction approval, providing structural drawings and engineer-stamped documents. Construction is strictly prohibited on cultivated land and basic farmland, requires approval from forestry departments for forest land, and is limited to temporary use on leased land. For example, the Beijing Metro Line 8 Qianmen project obtained compliant approval to use container houses for temporary offices, avoiding illegal construction risks.
