Description

Technical Field

[0001] The utility model relates to the technical field of pipe docking mechanisms, in particular to a pipe docking structure for construction of a subway dewatering well. Background Art

[0002] In deep foundation pit excavation projects, when the groundwater level is high, due to the soil-water pressure difference, groundwater may cause many adverse effects on the foundation pit, such as decreased foundation bearing capacity, water bubbling at the bottom of the pit, pipe gushing, sand flow and erosion, etc. Therefore, in order to ensure the safety of deep foundation pit construction, it is necessary to drain the foundation pit and lower the groundwater level.
