Device for recycling precipitation well concrete well pipe and using method thereof

Abstract

The invention provides a device for recycling a precipitation well concrete well pipe. The device comprises a support, a hoisting device and a gripper. The support is arranged at a well head. The hoisting device is arranged on the support. The gripper comprises a scissor support, a reinforcing rib plate and a touch foot. The reinforcing rib plate is arranged at the bottom of the scissor support. The touch foot is arranged on the reinforcing rib plate and is used for grasping the concrete well pipe. The invention further provides a using method of the device. Firstly, the support is erected atthe well head of the precipitation well, a reverse chain is arranged on the support, and the auxiliary lifting rope is hung on the reverse chain; and the gripper is assembled and is lowered into the concrete well pipe. The contact foot is subjected to tension to grab the pipe wall of the concrete well pipe and pull out the concrete well pipe. The method is low in cost and large in number of timesof recycling, saves materials and energy, and creates great social benefit.

Description

technical field [0001] The invention belongs to the field of underground engineering dewatering and drainage, and in particular relates to a device and a method for recovering concrete well pipes of a dewatering well. Background technique [0002] In the construction of underground drainage and drainage, many precipitation wells need to be built to dewater. At present, tube well dewatering is a widely used and relatively mature dewatering method. When using tube well dewatering, steel pipes, cast iron pipes, and cement are generally used in the prior art. tubes, plastic tubes, etc. Although the well pipe made of steel pipe and cast iron pipe has high strength and good water discharge effect, after the foundation pit is completed, there will be a lot of gravel around the well pipe, which leads to the one-time investment of the well pipe, which is not easy to recycle. Reuse will cause a certain waste of resources, and the cost will be higher while failing to meet the requirem...

AI Technical Summary

Problems solved by technology

Although the well pipe made of steel pipe and cast iron pipe has high strength and good water discharge effect, after the foundation pit is completed, a large amount of gravel is squeezed around the well pipe, which leads to the one-time investment of the well pipe, which is not easy to recycle and cannot Reuse, resulting in a certain waste of resources, high cost and can not meet the requirements of environmental protection
