Dewatering well system plugging device and construction method
The invention relates to a dewatering well system plugging device and a construction method. The plugging device comprises a bottom bracket, a well sealing plate, a rotary screwing rod and a top support; the bottom bracket is arranged at a plugging position of a dewatering well pipeline and comprises a supporting plate and a positioning nut supported at the center of the supporting plate through a first positioning part; a screwing nut is arranged at the top of the center of the well sealing plate, a matched positioning screw corresponding to the positioning nut is arranged at the bottom of the center of the well sealing plate, and threads of the screwing nut are opposite to those of the positioning nut; the rotary screwing rod comprises a connecting rod and a rotary handle mounted at one end of the connecting rod, and the other end of the connecting rod is provided with a matched screwing screw corresponding to the screwing nut; and the top support is arranged at the upper opening position of the dewatering well pipeline, and a positioning circular ring for the connecting rod to penetrate through is arranged in the center of the top support through a second positioning part. The plugging device can solve the problem that the water level in a dewatering well cannot be lowered due to the fact that the water pressure of a foundation pit bottom plate is too large, meanwhile, the well sealing quality is guaranteed, and the hidden danger of water seepage after well sealing is completed is reduced.
本发明涉及一种降水井系统封堵装置以及施工方法，封堵装置包括：底托架，设于降水井管道的封堵位置，底托架包括托板以及通过第一定位件支设于托板中心的定位螺母；封井板，封井板中心的顶部设拧接螺母，封井板中心的底部对应定位螺母设有配套的定位螺丝，拧接螺母的丝牙与定位螺母的丝牙相反；旋转拧杆，包括连接杆以及安装于连接杆一端的旋转把手，连接杆的另一端对应拧接螺母设有配套的拧接螺丝；顶支架，设于降水井管道上口位置，顶支架的中心通过第二定位件支设供连接杆穿过的定位圆环。本发明能够解决基坑底板水压过大，无法降低降水井内水位的难题，同时保证封井的质量，减小封井完成后出现渗水的隐患。
