How to build a rural two-story foundation

Rural two-story foundation construction method: survey and design, pre-preparation, construction trenching, foundation construction, precautions.

1, survey and design: before the official start of construction, the first thing to do is to survey the building site to understand the topography, geology, hydrology and other basic conditions. This step is important for determining the type of foundation, foundation size and construction methods. According to the results of the site survey, combined with the building load, the nature of the foundation soil and other factors, design the appropriate form of foundation. Common foundation forms include shallow buried type, deep buried type, raft foundation, box foundation and so on. In the countryside, the shallow buried reinforced concrete foundation is generally used.

2, pre-preparation: according to the foundation design, the preparation of detailed construction drawings, including foundation layout, cross-section drawings, detailed structural drawings. Drawings should be clearly labeled foundation size, material specifications, construction requirements. According to the foundation construction drawings, prepare the required materials, such as reinforcing steel, concrete, bricks and stones. Local construction materials can be used in rural areas to reduce costs.

3, construction trenching: according to the construction drawings, on-site line placement. The release line should be accurate and clear for subsequent construction. According to the scope of the line, digging out the original surface of the debris and loose soil layer, until reaching the design requirements of the holding layer. The stability of the base trench wall should be maintained during the trenching process to avoid collapse.

4, foundation construction: according to the type of foundation and design requirements, foundation construction. Common construction methods include brick foundation, stone foundation, concrete foundation and so on. In rural areas, concrete foundation construction is more common. After the completion of foundation construction, foundation acceptance. Acceptance includes foundation size, material quality, construction quality and so on. After acceptance, the upper building construction can be carried out.

5, notes: the construction process, to strengthen the foundation of the monitoring, found that timely measures to deal with the problem. Monitoring content includes foundation deformation, cracks, water level and so on. After the foundation acceptance, the upper building construction in accordance with the construction drawings. The construction process should ensure that the load of the building is evenly distributed to avoid uneven settlement of the foundation.
