Description

Technical Field

[0002] The foundation pit is an earth pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings on site, and waterproofing and drainage work should be done. If the excavation is not deep, the side slope can be used to stabilize the soil slope, and the slope size is determined according to relevant construction regulations. For deeper excavations and nearby buildings, foundation pit wall support methods and shotcrete wall protection methods can be used. Large foundation pits can even use underground continuous walls and column-type bored pile interlocking methods to prevent the outer soil layer from collapsing. If there is no impact on nearby buildings, the well point method can be used to lower the groundwater level, and slope open excavation can be used. After the excavation is completed, the foundation pit needs to be supported by supporting equipment;
