Wall pipe for dewatering well of deep well

The utility model discloses a wall pipe for a dewatering well of a deep well, comprising a steel pipe, a PVC pipe, a plurality of iron wires and PTFE tapes; the diameter of the steel pipe is less than that of the PVC pipe, one end of the steel pipe is inserted into one end of the PVC pipe to form a partial overlapped sleeved connection; the steel pipe is positioned above the PVC pipe, a plurality of pairs of through holes are arranged on the upper side and the lower side of the overlapped section of the steel pipe and the PVC pipe along a radial direction at intervals; the plurality of iron wires respectively penetrate into the plurality of pairs of the through holes and are bound; and the PTFE tapes are coated with the overlapped section of the steel pipe and the PVC pipe. The groundwater can be controlled by the dewatering well by using the wall pipe, thereby saving the cost, achieving high recycle rate of the steel pipe with less damage and ensuring the secondary utilization of the steel pipe.
