Deep well dewatering device and operation method thereof
The invention provides a deep well dewatering device and an operation method thereof. The deep well dewatering device comprises a dewatering well, an air extracting/injecting pipeline communicating with the dewatering well, a drainage pipe communicating with the dewatering well and an air extracting/injecting device arranged outside the dewatering well, wherein an underground water seepage deviceis arranged on the side wall of the dewatering well, a closed water collecting and draining device is arranged at the bottom of the dewatering well and communicates with the dewatering well through awater collecting one-way valve, one end of the air extracting/injecting pipeline is arranged in the water collecting and draining device, the other end of the air extracting/injecting pipeline is connected with the air extracting/injecting device, the air suction/injection pipeline communicates with the dewatering well through an air suction one-way valve, one end of the drainage pipe is arrangedat the bottom of the water collecting and draining device, the other end of the drainage pipe is arranged outside the dewatering well, and the air suction one-way valve is opened when the air suction/injection device sucks air and closed when the air is injected. By the adoption of the technical scheme, the underground water collecting and discharging efficiency can be improved.
本发明提供了一种深井降水装置及其运行方法，所述深井降水装置包括降水井、与所述降水井相连通的抽/注气管道、与所述降水井相连通的排水管及设置于降水井外的抽/注气装置，所述降水井的侧壁上设置有地下水渗流装置，所述降水井底部设置有一封闭的集排水装置，所述集排水装置通过一集水单向阀与所述降水井相连通，所述抽/注气管道的一端设置于所述集排水装置内，另一端与所述抽/注气装置相连接，所述抽/注气管道通过吸气单向阀与所述降水井相连通，所述排水管的一端设置与所述集排水装置底部，另一端设置于所述降水井外部，所述吸气单向阀在所述抽/注气装置抽气时打开，注气时关闭。采用本发明的技术方案，可以提高地下水收集和排出的效率。
