Plugging device for pressure-bearing dewatering well
The plugging device comprises a sealing cover plate, a steel sleeve and a water pumping steel pipe well, a first steel supporting ring is fully welded to the outer portion of the upper end of the water pumping steel pipe well in the circumferential direction, and a second steel supporting ring and a steel water stop ring are fully welded to the inner side and the outer side of the middle of the inner side and the outer side of the steel sleeve in the circumferential direction correspondingly. The lower end of the steel sleeve is centrally supported on the first steel supporting ring and welded through full-length welding, and the sealing cover plate is centrally supported on the second steel supporting ring and welded through plug welding. The method has the beneficial effects that the problems that a traditional precipitation well is slow in sealing and poor in plugging quality are solved, the weak link of construction water stopping can be effectively solved, the plugging quality of the precipitation well is improved, and the waterproof effect is good; the dewatering well plugging construction speed is high, construction of other working procedures is not affected, the construction progress is accelerated, the construction period is shortened, and the construction cost is reduced.
本发明提供了一种用于承压降水井的封堵装置，包括封盖板、钢套管和抽水钢管井，抽水钢管井上端外部沿圆周方向满焊第一钢托环，钢套管的内外中部的内外两侧沿圆周方向分别满焊第二钢托环和钢止水环，钢套管的下端居中支撑在第一钢托环上，并通过满焊焊接，封盖板居中支撑在第二钢托环上，并塞焊焊接。本发明的有益效果在于：解决了传统降水井封闭慢，封堵质量差的问题，能够有效解决施工止水薄弱环节，提高了降水井的封堵质量，防水效果好；本发明降水井封堵施工速度快，不影响其他工序施工，加快施工进度，缩短施工工期，降低工程造价。
