Lichuan Container House Construction
Information on container house construction in Lichuan needs to be combined with specific project planning and construction requirements. Currently, publicly available information does not directly cover specialized container house construction content, but key points can be summarized from similar projects:
1. Construction Qualifications and Preliminary Preparations Container house construction requires steel structure engineering professional contracting qualifications. Before construction, geological surveys, construction drawing design, and reviews must be completed. For example, the Lichuan Traditional Village Protection and Utilization Demonstration Village Construction Project (EPC model) explicitly requires geological survey reports, construction drawing designs, and specialized reviews. Container house construction must also meet specialized review requirements for structural safety, fire protection, power supply and distribution, etc.
2. Foundation Construction and Structural Installation Container house foundations must be designed according to geological conditions, commonly using reinforced concrete strip foundations or independent foundations. Taking the rural infrastructure project in Shizi Village, Liangwu Township, Lichuan as an example, its road reconstruction involves retaining walls, irrigation and drainage ditches, and other works. Container house foundation construction can refer to similar earthwork excavation, steel bar binding, and concrete pouring processes. Structural installation requires professional lifting equipment to ensure that the horizontal docking accuracy of container modules is controlled within ±3mm, and welding nodes must comply with the "Code for Acceptance of Construction Quality of Steel Structures" (GB50205).
3. Integrated Supporting Systems Container houses require integrated water supply and drainage, electrical, and heating, ventilation, and air conditioning (HVAC) systems. In the Lichuan City Second Sewage Treatment Plant project, sewage pipeline construction uses HDPE double-wall corrugated pipes, with burial depths meeting frost layer requirements; the electrical system requires reserved grounding terminals, and cable laying complies with the "Code for Design of Low-Voltage Distribution" (GB50054). If used in cold chain logistics scenarios (such as the Lichuan Smart Cold Chain Logistics Project), refrigeration units and temperature and humidity monitoring systems also need to be integrated, with equipment installation complying with the "Code for Design of Cold Stores" (GB50072).
4. Acceptance and Maintenance Standards After construction is completed, structural safety inspections, airtightness tests, and fire protection acceptance are required. After the main building of the Lichuan Domestic Waste Incineration Power Generation Project was capped, it entered the mechanical and electrical installation stage. Similarly, container houses must undergo equipment commissioning after the main structure is completed. In terms of maintenance cycles, steel structures require anti-rust treatment every 2 years, and sealing strips must be replaced every 5 years to ensure a service life of over 20 years for the house.
5. Localized Construction Resources Existing construction resources in Lichuan can support container house construction. According to job postings, local workers such as decoration carpenters, welders, and fire protection plumbers are available, with daily wages ranging from 300 to 470 yuan, meeting the needs of modular installation. Material procurement can rely on the Lichuan centralized procurement catalog, prioritizing local suppliers to reduce logistics costs.
