Before excavation, the excavation plan should be determined based on geological and hydrological data and in combination with the situation of nearby buildings on site, and waterproof and drainage work should be done well. For shallow excavations, the method of sloping the soil slope can be used to stabilize the soil slope, and the slope size is determined according to relevant construction regulations. A building foundation pit is a space excavated downward from the ground for the construction of the underground structure of a building.
