[0002] The foundation pit project mainly includes the design and construction of the foundation pit support system and earth excavation. It is a highly comprehensive system project, which requires close cooperation between geotechnical engineering and structural engineering technicians. The foundation pit support system is a temporary structure and is no longer needed after the underground engineering construction is completed. The foundation pit and the foundation trench are both used to build the foundation of a building, but the plane shape is different. The foundation pit is square or close to a square, and the foundation trench is long and sometimes longer. What you need to grasp is the difference in their shapes. The foundation pit refers to a foundation pit with a bottom area of less than 27 square meters and the long side of the bottom is less than three times the short side. The foundation trench refers to a trench bottom width of less than 3 meters and the trench length is greater than 3 times the trench width.
