Well closing casing pipe used for dewatering well, dewatering well and well closing method for dewatering well
The invention discloses a well closing casing pipe used for a dewatering well, the dewatering well and a well closing method for the dewatering well. The well closing casing pipe used for the dewatering well comprises a steel pipe, one or more water stopping rings, multiple inward concave components and multiple outer protruding components. The water stopping rings are connected with the outer wall of the steel pipe. One ends of the inward concave components are fixed to the inner wall of the steel pipe. The inward concave components are arranged along the inner wall of the steel pipe. One ends of the outward protruding components are fixed to the outer wall of the steel pipe. The outward protruding components are arranged along the outer wall of the steel pipe. Three water stopping rings are arranged on the outer side of the steel pipe of the well closing casing pipe, the underground water on the outer side of the casing pipe can be effectively prevented from moving upwards. Due to the fact that a stud is welded to the outer side of the steel pipe, the stability of connecting of the casing pipe and a raft is greatly improved, meanwhile due to the fact that a reinforcing steel bar head is welded to the inner side of the casing pipe, when the dewatering well is closed, the anchoring strength with the concrete can be enhanced, and the density can be enhanced.
