How to Pad Under Container Houses
The method of padding under container houses should be selected based on the usage scenario, foundation conditions, and house type. Common methods include prefabricated concrete pads, steel pads, moisture-proof pads, and brick-and-stone foundations. Details are as follows:
Short-term usage scenarios: If the container house is temporarily constructed, prefabricated concrete pads or steel pads can be used as bottom supports. The spacing between pads should not exceed 2 meters, and a crushed stone leveling layer should be laid beneath each pad to ensure all load-bearing points are on the same horizontal plane, preventing box distortion due to uneven ground. During lifting, sufficient-capacity steel cables should be used to ensure all lifting points bear force simultaneously, preventing box deformation caused by unilateral force. After placement, check the fit between the bottom beam and the pads. If there is local suspension, use thin steel sheets to pad it solid and use a level to check the levelness, with an error controlled within 2 millimeters per meter.
Moisture-proof requirement scenarios: If the container house is placed on unhardened ground such as soil or grass for an extended period, moisture-proof pads should be laid at the bottom, moisture-proof base materials should be added inside the wall panels, and bottom ventilation slots should be installed to疏导 ground moisture. This design effectively prevents the box from getting damp and moldy, suitable for scenarios such as suburban warehouses and field guardhouses.
Poor foundation condition scenarios: For foldable container houses or fixed residential container houses, if the foundation conditions are poor, simply level the ground and place the box directly. If possible, pour a concrete floor and install drainage ditches to enhance living comfort. Packing-box container houses have even lower foundation requirements and can even be placed directly on the ground without a foundation.
Long-term usage or humid area scenarios: In humid areas or scenarios requiring long-term use, brick-and-stone foundations can be built at the bottom of the container to create a more stable structure. For example, a three-story container residence used a brick-and-stone-built basement as its foundation, effectively avoiding corrosion problems caused by direct contact between the steel box and moist soil.
