Description

Technical Field

[0001] The utility model belongs to the technical field of deep foundation pit pipe wells, in particular to a deep foundation pit pipe well dewatering device. Background Art

[0002] Since the cycle of deep foundation pit dewatering projects is often long, and the flow rate of the water collection pipes is large when the water level is high and in the rainy season, the water collection main pipe in the well point dewatering system is likely to cause silt accumulation, affecting the dewatering efficiency and further affecting the stability of the foundation pit support structure. The traditional solution is to rely solely on the drainage well filter pipe and filter material layer in the foundation pit to filter the silt. Some of the silt will still enter the subsequent dewatering pipes. When the precipitation cycle is long and there are more rainy seasons, most of the silt will accumulate in the water collection main pipe around the top of the foundation pit, affecting the precipitation efficiency and making it difficult to clean up. Utility Model Content

[0003] The purpose of the utility model is to provide a deep foundation pit pipe well dewatering device. The utility model adopts a combined installation method and is divided into four independent parts, namely a cleaning port, a pressure ring, a mounting ring and a filter screen.
