Ruili Container House Installation
The installation of container houses in Ruili should incorporate the characteristics of modular construction, adhering to the principles of factory prefabrication and rapid on-site assembly. The core steps include foundation preparation, module transportation, on-site lifting, electromechanical connection, and acceptance testing.
1. Foundation Preparation and Site Adaptation
Before installing container houses, ensure the site is level and design the foundation form based on the house type (e.g., single-story, double-story, or multi-story stacking). Both light steel frames and concrete foundations are acceptable, but they must meet load-bearing requirements. For example, the folding container base of Sichuan KuaiZhu Integrated Housing uses galvanized formed parts with a calcium silicate board floor, which can be placed directly on hardened ground, reducing on-site construction. For mountainous or complex terrains, adjustable supports or pile foundations are required to ensure house stability.
2. Modular Unit Transportation and Lifting
After prefabrication in the factory, house modules are transported to the site via container trucks. Lifting requires professional lifting equipment, with the appropriate crane tonnage selected based on house size. For example, a 40-foot standard container module weighing approximately 3-5 tons requires a crane with a capacity of over 25 tons for lifting. During lifting, pay attention to module orientation to avoid collisions and ensure lifting points align with the module's designed load-bearing points to prevent structural deformation.
3. On-Site Assembly and Connection
Once modules are in place, assemble them using bolts or quick connectors. Focus on checking the sealing of walls, roofs, and floors to prevent water leakage. For example, Shengshan Integrated Housing's modular houses use a welding-free quick assembly process with high-strength bolts, resulting in low disassembly losses and multiple reusability. After assembly, install doors, windows, stairs (for multi-story structures), and external decorative panels to complete house functionality.
4. Electromechanical System Connection and Testing
The electromechanical systems (e.g., water, electricity, and HVAC) of container houses are prefabricated in the factory, requiring only main pipeline connections on-site. For example, Suzhou Zhishang Integrated Housing's packing container houses come with pre-installed water and electricity lines, requiring only connection to the main power and water sources for use. During testing, check the operation of lighting, sockets, air conditioners, and other equipment to ensure no electrical leakage or short circuits.
5. Acceptance and Delivery
After installation, conduct acceptance testing according to national standards (e.g., GB/T 23932-2009), focusing on structural safety, fire resistance, and environmental indicators. For example, portable houses must meet requirements for seismic intensity 7 and wind load resistance of 0.55 kN/㎡. Upon passing acceptance, deliver the house for use and provide a maintenance manual and warranty service.
