Prefabricated Foundation for Rural Houses

The prefabricated foundation for rural houses is constructed using prefabricated components, featuring rapid construction and a high degree of standardization. Here is a detailed introduction to the prefabricated foundation for rural houses:

Assembly Method of Prefabricated Foundations

There are cases of using prefabricated components for assembly. For example, foundation piles weighing 5 tons are fixed using base plates, and the crossbeams are quickly connected using mortise-and-tenon joints, similar to building with blocks. Stairs can also be hoisted, followed by laying a 5-centimeter-thick floor slab, and finally grouting all component gaps to complete the foundation construction.

Foundation Construction Precautions

• Soil Investigation: The soil quality of the homestead cannot be judged solely by experience; it must be investigated in advance. Based on different soil conditions, choose an appropriate foundation form. For example, on soft soil foundations, special forms such as pile foundations may be required to enhance the foundation's bearing capacity.
• Foundation Pit Dimensions: The depth and width of the foundation pit cannot be determined arbitrarily. Taking a strip foundation as an example, the pit depth should be based on reaching the hard soil layer. If it is difficult to determine or the foundation requires soil replacement, it should be dug to a depth of at least 1.2 - 1.5 meters, with a pit width of at least 0.8 meters, to ensure the stability of the foundation.
• Cushion Layer Setting: A cushion layer is essential, typically using C10 or C15 plain concrete with a thickness of 10 centimeters. The cushion layer serves multiple purposes: it evenly distributes the upper load to the foundation, provides a flat working surface for steel bar binding, and isolates moisture from the soil to prevent steel bar corrosion.
• Steel Bar Binding: Steel bar binding must comply with regulations. The number, diameter, and stirrup spacing of the main steel bars in the ground beam must be precisely calculated. The lap length of the steel bars must be sufficient, and spot welding cannot replace binding. Additionally, national standard products must be used to ensure the connection strength of the steel bars and the stability of the overall structure.

Trends Related to Prefabricated Foundations

Prefabricated concrete houses have become a new trend in rural self-built housing, featuring standardized factory production and on-site assembly construction. Foundation bases are also one of their main products. Furthermore, when raising the foundation of rural houses for moisture prevention, both prefabricated slabs and soil filling methods can be used. The choice between prefabricated slabs and soil filling should be based on local actual conditions, construction conditions, and economic capabilities.
