Foundation Construction for Rural Container Houses
The foundation construction for rural container houses should be determined based on the type of container and the actual conditions of the residential land. Generally, the ground needs to be leveled, and if conditions permit, a cement floor can be poured and proper drainage can be provided. In special cases, strip foundations or raft foundations should be constructed according to regulations.
Ordinary Foldable/Fixed Container Houses: These have relatively low foundation requirements. Simply level the ground of the residential land to ensure stable placement. If possible, pour a cement floor and set up drainage ditches to enhance living comfort and drainage capacity, preventing water accumulation from affecting the stability of the house.
Packing Container Houses: The foundation requirements are relatively simple. Strip foundations or pier foundations can be chosen, and in certain conditions, they can even be placed directly on the ground. However, it should be noted that if the soil quality of the residential land is poor (such as backfill soil or mixed soil layers), the soft soil layer should be excavated to reach the original undisturbed soil to ensure a stable foundation.
Special Geological Conditions: If the residential land is located in low-lying areas, wetlands, or paddy fields, it is recommended to use raft foundations or pile foundations to distribute the load of the house and prevent foundation settlement. In cold northern regions, the influence of permafrost should be considered, and the foundation depth should be below the permafrost layer to avoid wall cracking caused by frost heave.
Compliance Requirements: Placing container houses must comply with land management regulations, and procedures for changing the land use nature and obtaining approvals must be completed. Unauthorized placement or change of use (such as converting to residential or business premises) without approval may be considered illegal construction and face the risk of demolition.
Construction Details: If a strip foundation is used, steel bars should be configured according to regulations (main bars with a diameter of 12-14 millimeters and a spacing of 15-20 centimeters; distribution bars with a diameter of 8 millimeters and a spacing of 20 centimeters), and concrete should be poured. The foundation should be cured for at least 7 days, and backfilling can only be carried out after the strength meets the standard to prevent cracking.
