Rapid well completion dewatering device for dewatering well and construction method of rapid well completion dewatering device
The rapid well completion dewatering device for the dewatering well comprises a reinforcement cage framework, a steel wire mesh and a submersible pump, a rotary drilling pile casing is arranged on the inner wall of the dewatering well in a follow-up mode, the rotary drilling pile casing is detachably pulled out, the steel wire mesh wraps the reinforcement cage framework, the reinforcement cage framework and the steel wire mesh are arranged in the rotary drilling pile casing, and the submersible pump is arranged in the reinforcement cage framework. The submersible pump communicates with the outside through a water pumping pipe. By means of the simple device, the water head of the foundation pit is lowered, the construction cost is lowered, it is guaranteed that soil particles are not lost from the construction technology, sedimentation of surrounding buildings is prevented, and the precipitation requirement is met.
一种降水井快速成井降水装置及其施工方法，包括钢筋笼骨架、钢丝网和潜水泵，降水井内壁跟进设置旋挖钻护筒，旋挖钻护筒可拆卸抽除，钢筋笼骨架外包裹钢丝网，钢筋笼骨架和钢丝网设置在旋挖钻护筒内，钢筋笼骨架内设置潜水泵，潜水泵通过抽水管与外部连通。通过本发明的简易装置，既降低基坑水头，又降低了施工成本，从施工工艺上保证了土体颗粒不流失，又防止周边建筑物发生沉降，达到了降水要求。
