Well sealing device for dewatering well
A well sealing device for a dewatering well comprises a steel sleeve, a water pumping pipe and a screwed plug, and is characterized in that a steel water stop ring is arranged in the middle of the circumference of the steel sleeve in the radial direction, a steel supporting ring is arranged on the lower portion of the circumference of the steel sleeve below the steel water stop ring in the radial direction, and the steel sleeve is used for being sleeved with a concrete pipe and supporting the concrete pipe in a sleeved mode; a steel plugging plate is arranged at the upper end in the steel sleeve, an internal thread is arranged in the center of the steel plugging plate, and an inner pipe is mounted in the internal thread and is in threaded connection with the steel plugging plate; the water pumping pipe is matched with a water pump, the water pump is arranged on bottom plate concrete outside the dewatering well, and the water pumping pipe extends to the bottom of the dewatering well through the top end of the inner pipe; and the screwed plug is movably arranged at the top opening of the inner pipe. The well sealing device for the dewatering well has the advantages of being high in well sealing efficiency, few in hidden danger and small in cost input.
一种降水井封井装置，包括钢套管、抽水管、丝堵，其特征在于：所述钢套管圆周中部径向设有钢止水环，钢止水环下方在钢套管圆周下部径向设有钢支撑环，钢套管用于套入混凝土管，且使钢套管套支撑于混凝土管上；钢套管内部上端设有钢封堵板，钢封堵板中心设有内螺纹，内螺纹中安装有内管，内管与钢封堵板螺纹连接；所述抽水管配合抽水泵，抽水泵设置于降水井外底板混凝土上，抽水管通过内管顶端直至降水井底；所述丝堵活动设置在内管顶口。本发明的降水井封井装置具有封井效率高、隐患少和成本投入小的优点。
