Flat rotating gate type dewatering well plugging device
The invention relates to a flat rotating gate type dewatering well plugging device. The flat rotating gate type dewatering well plugging device comprises a bottom sealing steel plate, a fastening bolt, a sliding pad, a sunk screw, a rotating steel plate, torsion bayonet locks, a gasket, a fastening nut, a steel sleeve and a T-shaped wrench, and is characterized in that water outlet holes are formed in the bottom sealing steel plate, the sliding pad and the rotating steel plate, the bottom sealing steel plate is fixed to the bottom of the steel sleeve, the middle of the bottom sealing steel plate is perforated, a fixing bolt is connected through plug welding, the fixing bolt sequentially penetrates through the sliding pad, the rotating steel plate and the gasket, the top of the fastening bolt is screwed into the fastening nut to be tightened and compacted, the sliding pad is fixed on the bottom sealing steel plate, the bottom sealing steel plate and the water outlet holes of the sliding pad are aligned up and down, the two torsion bayonet locks are symmetrically connected and fixed to the top, close to the circle center position, of the rotating steel plate in a welded mode, two clamping grooves in the bottom of the T-shaped wrench match with the two torsion bayonet locks, the T-shaped wrench is rotated to drive the rotating steel plate to rotate, and closed water stopping is achieved. The flat rotating gate type dewatering well plugging device is applied to plugging construction of common and pressure-bearing dewatering wells, the structure is simple, the construction efficiency can be improved, leakage is reduced, and the cost is saved.
本发明涉及一种平板旋转闸式降水井封堵装置，包括封底钢板、紧固螺栓、滑垫、沉头螺钉、转动钢板、扭转卡销、垫圈、紧固螺帽、钢套筒、T型扳手，其特征在于：封底钢板、滑垫和转动钢板上均设有出水孔，钢套筒底部固定封底钢板，封底钢板中部穿孔塞焊固定螺栓，固定螺栓上依次穿过滑垫、转动钢板和垫圈，紧固螺栓顶部旋入紧固螺帽拧紧压实；滑垫固定在封底钢板上，且封底钢板和滑垫的出水孔上下对齐；转动钢板顶部靠近圆心处对称焊接固定两个扭转卡销，T型扳手底部的两个卡槽与两个扭转卡销相吻合；转动T型扳手带动旋转钢板转动，实现封闭止水。本发明应用于普通、承压降水井封堵施工，构造简单，可提高施工效率、减少渗漏，节约成本。
