Dongning Container House Installation

The installation of container houses in Dongning City requires adherence to standardized procedures and attention to key considerations, as detailed below:

Installation Process

1. Site Preparation

   • Select a flat area with good drainage, clear the ground of debris (such as stones and vegetation), and ensure a solid foundation. If the ground is soft or sloped, it should be compacted or leveled to prevent house tilting due to later settlement.
   • Conduct level measurements before construction, using a laser level or traditional spirit level to ensure site error does not exceed ±5mm, providing an accurate reference for subsequent foundation work.

2. Foundation Construction

   • Design the foundation structure based on container specifications (e.g., 20-foot or 40-foot standard containers). Common methods include:
     • Steel Structure Foundation: Suitable for temporary or movable scenarios, securing container corner fittings with embedded anchor bolts;
     • Concrete Foundation: Used for permanent buildings, requiring the pouring of strip or isolated foundations with depths determined by geological conditions (generally ≥50cm).
   • Reserve positions for electrical and plumbing connections during foundation construction to ensure alignment with the container's bottom layout.

3. Installation Process

   • Use a crane or forklift to lift container modules above the foundation, slowly lower them to the contact surface, and manually adjust for levelness and alignment to prevent deformation from collisions.
   • When joining multiple modules, secure them with corner bolts or welding to ensure seamless connections, preventing water leakage or structural loosening.

4. Connection and Fixing

   • When installing doors and windows, use waterproof sealant to fill gaps, ensuring airtightness and watertightness; reinforce connections between floors and walls to prevent delamination after prolonged use.
   • Electrical wiring (e.g., lighting, sockets) and plumbing (e.g., water supply and drainage) should be carried out by certified electricians and plumbers, complying with the "Code for Acceptance of Construction Quality of Electrical Installations in Buildings" and local standards.

5. Interior Decoration

   • After installing water and electricity facilities, proceed with wall and floor decoration (e.g., laying floors, applying wallpaper). When furnishing, consider the container's load-bearing capacity to avoid concentrating heavy objects.

Precautions

1. Professional Team Operation

   • Container house installation involves knowledge in structural mechanics, electrical safety, and other fields, requiring completion by a qualified construction team. Unauthorized structural modifications by non-professionals are prohibited.

2. Adherence to Standards and Guidelines

   • Strictly follow the manufacturer's "Installation Manual" and comply with local regulations such as Dongning City's "Building Safety Management Regulations", ensuring standards for fire exit width, emergency exit settings, etc., are met.

3. Safety and Environmental Protection

   • Check container materials (e.g., steel thickness, corrosion resistance) for compliance with load-bearing requirements, avoiding overloading; regularly inspect connecting components (e.g., bolts, rivets) for looseness.
   • Implement noise reduction (e.g., using low-noise equipment) and dust suppression (e.g., watering and covering) measures during construction to minimize impact on surrounding residents.

4. Functional Design Optimization

   • Design ventilation systems based on usage scenarios (e.g., residential, office). In high-humidity areas, lay moisture-proof membranes at the container's base; for basement scenarios, install additional drainage pumps.
