Description

Technical Field

[0001] The utility model belongs to the technical field of foundation pit dewatering, and in particular relates to a pneumatic dewatering device. Background Art

[0002] Dewatering works refer to the excavation of deep foundation pits in areas with high groundwater levels. As the aquifer is cut off, groundwater will inevitably seep into the foundation pit under the action of pressure difference. If the foundation pit dewatering work is not carried out, the foundation pit will be flooded, which will deteriorate the on-site construction conditions and reduce the bearing capacity of the foundation. Under the action of dynamic water pressure, it may also cause sand flow, pipe bursts and slope instability. Therefore, in order to ensure the safety of foundation pit construction, effective dewatering and drainage measures must be taken. At present, during the dewatering construction process, pneumatic dewatering pumps are usually used to transport the infiltrated water into the pit to extract it. The pneumatic dewatering pump is connected to a hoisting rope, an air pipe and a water pipe. At present, most of the water pipes and air pipes on the pneumatic dewatering pumps are directly scattered at the mouth of the pit, which is not convenient for on-site management and is easy to cause damage to the air pipe and water pipe, affecting the service life of the air pipe and water pipe.
