Construction of New-Type Container Houses

The construction of new-type container houses mainly adopts a modular construction method, where the house is disassembled into standardized modules, prefabricated in factories, and then transported to the site for assembly.

I. Modular Construction Process

1. Factory Prefabrication: Inside the factory, the house is divided into independent modules such as the floor, roof, and four sides. Through an assembly line, the main structure, water and electricity pipelines, bathroom waterproofing, bathroom fixtures, cabinets, wardrobes, and other interior decorations, and even soft furnishings are completed. For example, a smart factory in Guangdong has a daily module production capacity of 50 units, with a manufacturing precision stable at 1-2 millimeters.
2. Transportation and Hoisting: The prefabricated modules are shipped to their destination by container ships and precisely positioned using hoisting equipment. For example, the modular houses exported from the Shenzhen-Shanwei Special Cooperation Zone to Australia can be quickly assembled on-site after a 20-day voyage by cargo ship.
3. On-Site Assembly: After arriving at the site, the modules are assembled using bolts or welding, combined with supporting steel structure roof trusses and other loose parts to build the overall framework. Only water and electricity connections are needed for 'move-in readiness'. For example, the 63 modular elderly care apartments purchased by British merchants took only two weeks from shipment to completion of hoisting.

II. Technical Advantages

1. Efficient Parallel Operations: Traditional construction adopts a series construction method, while modular construction completes multiple processes simultaneously in the factory, completely transforming on-site work patterns. For example, the overall delivery cycle of a hotel project by China Construction Science & Industry Corporation in Papua New Guinea was shortened from 14-18 months to 7 months.
2. Quality Control: Factory standardized production reduces human errors, with steel consumption only 3%-5%, far lower than the 8%-12% on traditional construction sites. For example, the packing boxes produced by Suzhou Zhongnan Steel Structure Co., Ltd. have a wind resistance rating of Level 12, an earthquake resistance rating of Level 8, and a frame deformation rate of only 0.18%.
3. Environmental Sustainability: Modular construction reduces basic ground material consumption by 60%-70%, with less construction noise and waste, and steel can be recycled. For example, the steel consumption of a single standard 20-foot container is about 1.2 tons, and its carbon emissions are only 1/2.3 of those of traditional concrete temporary houses.

III. Application Scenarios

Container houses have been widely used in temporary offices, accommodations, event support facilities, data centers, and other fields. For example, Malaysia's 2312 project, as the world's first ultra-large prefabricated modular data center, had a construction period of less than 10 months, nearly half that of traditional methods.
