Container House Relocation Plan
The relocation of container houses requires comprehensive consideration of structural stability, lifting and transportation conditions, and compliance. The core steps include preliminary preparation, professional lifting, transportation securing, and installation and commissioning.
I. Preliminary Preparation: Structural Inspection and Foundation Treatment Before relocation, a comprehensive inspection of the container house is necessary to confirm that the steel structure is free from rust, deformation, or loose connectors, with particular attention to load-bearing parts such as corner columns and bottom beams. If the house has been in long-term use, the quality of welds should be tested, and reinforcement should be carried out if necessary. Meanwhile, the foundation should be treated according to the geological conditions of the new site to ensure that the flatness error does not exceed ±50mm, preventing structural cracking due to foundation settlement. For example, container houses used outdoors for a long time require concrete piers to be poured at the bottom to enhance moisture resistance and seismic performance.
II. Professional Lifting: Selection of Appropriate Lifting Points and Equipment Special lifting devices should be used for lifting container houses to avoid direct bundling with steel wires, which may cause deformation of the container body. A 40-foot container typically weighs about 3.8 tons, and an 8-16 ton crane should be selected based on the weight. The lifting points should be located at the corner fittings at the top four corners of the container body, which are designed load-bearing points of the container, capable of dispersing stress and preventing local deformation. If the house has been modified into a multi-story structure or additional facilities have been added, the center of gravity position should be recalculated, and the distribution of lifting points should be adjusted.
III. Transportation Securing: Anti-Displacement and Collision Measures During transportation, special towing vehicles or flatbed trucks should be used, and the container should be securely locked to the vehicle body through corner fitting securing devices to prevent sliding. Buffer materials should be filled between container bodies to prevent damage to doors, windows, and exterior wall panels due to transportation bumps. For foldable container houses, they should be transported in a folded state to lower the center of gravity, and after unfolding, the tightness of connecting components such as hinges and locks should be checked. For example, the third-generation foldable container from Tengfei uses support rods to maintain stability in the unfolded state, and it is necessary to ensure that the support rods are properly stowed during transportation.
IV. Installation and Commissioning: Leveling Correction and Functional Testing At the new site, a laser level should be used to adjust the levelness of the container, with an error controlled within ±3mm/m to prevent difficulties in opening doors and windows or tilting of interior furniture. When connecting water and electricity pipelines, it is necessary to verify whether the positions of reserved interfaces match the layout of the new site's pipeline network to avoid forced bending that may cause pipeline rupture. After installation, airtightness and watertightness tests should be carried out to ensure no leakage. For container houses equipped with photovoltaic panels or intelligent systems, the operation status of electrical equipment should also be debugged.
