Pressure-bearing dewatering well and well sealing construction method of pressure-bearing dewatering well

LI LIN / YANG YANG / ZHANG YOUYI

The invention discloses a pressure-bearing dewatering well and a well sealing construction method of the pressure-bearing dewatering well. The pressure-bearing dewatering well comprises a dewatering well body which is vertically arranged; the drainage assembly is arranged in the dewatering well body and used for draining underground water in the dewatering well out of the well; the supporting device comprises an outer supporting assembly and an inner supporting assembly, the outer supporting assembly is arranged on the outer side of the dewatering well body and used for positioning and supporting the dewatering well body, and the inner supporting assembly is arranged in the dewatering well body and connected with the outer supporting assembly. According to the pressure-bearing dewatering well and the well sealing construction method of the pressure-bearing dewatering well, continuous dewatering can be conducted in the dewatering well through a drainage device during well sealing construction, and the situation that due to the fact that the seepage flow speed of underground water of the pressure-bearing dewatering well is large, concrete of the dewatering well cannot be poured is avoided; the quality of well shut-in construction is effectively improved, and the economical efficiency of construction is improved.

一种承压降水井以及承压降水井的封井施工方法，包括：降水井本体，所述降水井本体竖直设置；排水组件，所述排水组件设置于降水井本体的内部用于将降水井内的地下水排出至井外；支撑装置，所述支撑装置包括外支撑组件和内支撑组件，所述外支撑组件设置于降水井本体的外侧同于定位和支撑降水井本体，所述内支撑组件设置于降水井本体内部并与外支撑组件相连接。本发明公开了种承压降水井以及承压降水井的封井施工方法，本发明可以在封井施工的时候通过排水装置在降水井内持续降水，避免了因承压降水井地下水渗水流速较大，导致降水井混凝土无法浇筑的情况发生，有效提高了封井施工的质量，提高了施工的经济性。
