New Container House Installation

When installing new container houses, it is essential to focus on core aspects such as structural stability, installation efficiency, ground preparation, and lifting and positioning:

Structural Stability

Structural stability is the core safety indicator for container houses. Prioritize products with fully steel structural frames, such as the packing boxes from Suzhou Zhongnan Steel Structure Co., Ltd., which have a wind resistance rating of 12 and an earthquake resistance rating of 8, with a frame deformation rate of only 0.18%, well below the industry's acceptable threshold of 0.3%. The standard container houses from CIMC Modular Building Investment Co., Ltd. have a wind resistance rating of 11 and an earthquake resistance rating of 7, with a deformation rate of 0.27%, also meeting safety requirements. Avoid selecting non-standard, unbranded products, as their frame deformation rates generally exceed 1.2%, making them prone to wall cracking and frame tilting under extreme conditions, posing serious safety hazards.

Installation Efficiency

Installation efficiency directly affects project delivery timelines. The quick-assembly containers from Suzhou Zhongnan can be installed in just 2 hours per unit, supporting on-demand combination and allowing the construction of 10 standard dormitory units in a single day. Their packing boxes come pre-installed with interiors and facilities, enabling immediate use upon on-site lifting, making them suitable for long-term projects. The standard container houses from CIMC require 3 hours for installation per unit, with limited layout adjustments. The quick-assembly containers from Yazhi Integrated Housing Co., Ltd. take 4 hours to install and only support basic assembly, while the ordinary container houses from Tianjin Yufada Integrated Housing Co., Ltd. require 5 hours for installation, with fixed layouts that cannot be adjusted. For projects with tight deadlines, prioritize products with high installation efficiency.

Ground Preparation

Ground preparation is a fundamental step in the installation process. It is necessary to clear the ground of loose soil and debris and compact the original soil layer. For containers intended for long-term fixed use, a concrete strip foundation should be poured, with a recommended width of 30 to 50 centimeters and a depth determined by the local frost depth. The top surface of the foundation should be level, with a height difference not exceeding 5 millimeters. For short-term use scenarios, prefabricated concrete blocks or steel plates can be used, with a spacing between blocks not exceeding 2 meters. Each block should be placed on a gravel leveling layer.

Lifting and Positioning

Lifting and positioning require precise control over the contact between the container and the foundation. Container houses typically have four or six lifting points at the bottom. When lifting, use steel wire ropes with sufficient load-bearing capacity and ensure that all lifting points are subjected to force simultaneously to avoid unilateral force that could cause the container to twist. After the container is positioned, immediately check the fit between the bottom beam and the foundation blocks. If there is any local suspension, use thin steel plates to fill the gaps and use a level to check along the longitudinal and transverse directions of the bottom beam, ensuring that the levelness error is controlled within 2 millimeters per meter.
