Plugging device for drainage hole of dewatering well and lengthening and sealing construction method for dewatering well
The invention discloses a dewatering well drain hole plugging device and a dewatering well extension sealing construction method, and the device comprises an inner pressing plate which is arranged on the inner side of a well casing body to shield an inner hole opening of a dewatering well drain hole; the outer pressing plate is arranged on the outer side of the well casing body to shield an outer hole opening of the drainage hole; elastic blocking lining layers are arranged between the elastic blocking lining layers, the inner pressing plate and the inner side of the well casing body and between the outer pressing plate and the outer side of the well casing body respectively, annular protruding edges are formed on the elastic blocking lining layers, and the annular protruding edges of the two elastic blocking lining layers are embedded in the inner annular groove and the outer annular groove of the well casing body respectively; the tie rod is movably arranged in the drainage hole in a penetrating mode, one end of the tie rod is connected to the inner pressing plate in a spherical hinge mode, and the other end of the tie rod is detachably connected to the outer pressing plate. The problem that when extension welding construction is conducted on the precipitation well, underground water in the precipitation well upwells, and normal extension welding construction is affected is solved.
本发明公开了一种降水井泄水孔封堵装置及降水井接长封闭施工方法，包括：内压板，设置于井管本体的内侧以遮蔽降水井泄水孔的内孔口；外压板，设置于井管本体的外侧以遮蔽泄水孔的外孔口；弹性封堵内衬层，内压板与井管本体的内侧之间、以及外压板与井管本体的外侧之间分别垫设有弹性封堵内衬层，弹性封堵内衬层形成有环向凸楞，两弹性封堵内衬层的环形凸楞分别嵌设于井管本体的内环槽和外环槽中；拉结杆，拉结杆可活动地穿设于泄水孔中，拉结杆的一端球铰连接于内压板，拉结杆的另一端可拆卸地连接于外压板。本发明解决了在对降水井进行接长焊接施工时，降水井内的地下水上涌影响正常接长焊接施工的问题。
