A foundation pit is a soil pit excavated at the design location of the foundation according to the elevation of the foundation and the plane size of the foundation. Before excavation, the excavation plan should be determined according to the geological and hydrological data and the conditions of nearby buildings on site, and waterproof and drainage work should be done. If the excavation is not deep, the side slope can be used to stabilize the soil slope, and its slope size shall be determined according to the relevant construction regulations. For those who excavate deeper and have nearby buildings, foundation pit wall support methods, sprayed concrete wall protection methods, large-scale foundation pits even use underground continuous walls and column-type bored pile interlocking methods to protect the outer soil layer from collapsing For those who have no influence on nearby buildings, the well-point method can be used to lower the groundwater level, and the slope can be used for open excavation; in cold areas, natural air-conditioning freezing method can be used for excavation, etc.
