Anti-blocking device for well-point dewatering leakage net
A well hole is dug around a foundation pit, the well point dewatering device comprises dewatering pipes embedded in the well hole, a water pumping main pipe connected with the dewatering pipes and a water pump, and the leakage net anti-blocking device is fixedly installed at the bottoms of the dewatering pipes and communicated with the dewatering pipes. The leakage net anti-blocking device comprises a pipe wall, a conical leakage net and a cleaning mechanism. The diameter of the pipe wall is consistent with that of the downcast pipe, the pipe wall is fixed to the bottom of the downcast pipe, the side wall of the pipe wall is provided with a plurality of strip-shaped water passing holes, the strip-shaped water passing holes are evenly distributed in the circumferential direction of the pipe wall, and the water pumping efficiency of the downcast pipe is improved. The conical leakage net is fixed to the bottom of the pipe wall, and a plurality of water permeable holes are formed in the conical leakage net. The cleaning mechanism comprises a rotating shaft arranged in the center of the pipe wall and a cleaner installed on the rotating shaft, the cleaner is inserted into the strip-shaped water passing hole, the cleaner can slide in the extending direction of the strip-shaped water passing hole so as to clean the strip-shaped water passing hole, and smoothness of the strip-shaped water passing hole is guaranteed.
本发明公开了一种井点降水漏网防堵装置，基坑周围挖设有井孔，井点降水装置包括埋入井孔的降水管、连接各降水管的抽水总管以及水泵，漏网防堵装置安装固定至降水管的底部并连通降水管，漏网防堵装置包括管壁、锥形漏网以及清理机构。管壁与降水管的直径一致，且管壁固定至降水管的底部，管壁的侧壁开设有若干条形过水孔，各条形过水孔沿管壁的周向方向均匀分布，增加降水管的抽水效率。锥形漏网固定至管壁的底部，锥形漏网上开设有若干透水孔。清理机构包括设于管壁中心位置的转轴以及安装至转轴的清理器，清理器插入条形过水孔，清理器能够沿条形过水孔的延伸方向滑动以对条形过水孔进行清理，保证条形过水孔的通畅性。
