Research on key technologies of dewatering of pneumatic well point in foundation pit
Deep foundation pit excavation,due to deep underground a distance,so when the scope of the foundation pit is large,it will contact with different types of groundwater.The traditional drainage method is difficult to discharge a large amount of groundwater,which affects the stability of the foundation pit,the safety of the enclosure structure,and even the safety of the surrounding buildings.Starting from the dewatering measures during the excavation of foundation pit,the paper emphatically discusses the technical application and construction method of air floating in foundation pit,which can be used as reference for similar projects.The above measures can effectively solve the drainage problems in the process of foundation pit excavation,so as to ensure the quality and safety of construction.
