Embodiment 1

[0035] This embodiment discloses a method for dredging a cable protection tube, which includes the following steps:

[0036] S1. Take the cable pipe threader, pass the thread of the cable pipe threader through one end of the cable protection pipe 1, and lead it out from the other end;

[0037] S2. Attach a dredger 2 that can break and collect soil clods at the threading outlet end of the cable pipe threader. The other end of the dredger is tied with a pull rope 10 and connected to the driving device I, and then pulled by the cable pipe threader. The dredge to the other end of the cable protection tube;

[0038] S3. After pulling out the dredger, remove the cable threading device tied to the dredge, and tie the rope to connect to the driving device II;

[0039] S4. By controlling the alternate action of the driving device I and the driving device II, the driving device I and the driving device II pull the dredger to move back and forth repeatedly in the cable protection tube t...

Embodiment 2

[0054]Embodiment 2 is on the basis of Embodiment 1. It is also provided with a control unit for controlling the on-off of the motor switch, which is located at both ends of the cable protection tube to detect the status of the dredger entering and exiting the cable protection tube. The infrared detection The device is electrically connected to the control unit; the control unit controls the two driving devices to act alternately according to the feedback information of the infrared detector, specifically: when the driving device I operates, the driving device II does not operate, and the cable is stretched out after the infrared detector detects the dredger, etc. When the protection tube is at one end of the driving device I, the two driving devices are controlled to operate alternately (the driving device I does not operate, and the driving device II operates), and so on.

Abstract

The invention relates to a cable protection pipe dredging method which comprises the following steps of dredging by dredging devices, collecting clods, collecting smashed clods, flushing with water, removing accumulated water, wiping the inner part of the pipe, and drying the inner wall of the pipe with hot air. The cable protection pipe dredging method thoroughly solves the problem that the cable protection pipe cannot be dredged, the cleanliness of the inner part of the cable protection pipe is improved, and a good protection effect of the cable protection pipe on a cable is achieved.

Description

technical field [0001] The invention relates to the field of electric power construction, in particular to a method for dredging a cable protection pipe. Background technique [0002] As a trenchless construction technology, cable jacking construction technology is generally applicable in the cable laying process in the power industry. The main process includes exploration of underground cable paths, pipe jacking conduction, underground penetration of cable protection pipes, and laying of power cables through pipes. Among them, in the underground penetration link of the cable protection pipe, during the process of pulling the cable protection pipe (PE pipe) by the underground reamer, due to the poor sealing of the cable protection pipe mouth and scratches by underground hard objects (stones, tiles, etc.), It will often cause part of the soil to enter the pipe, which will easily cause the internal blockage of the laid cable protection pipe, which will affect the laying proce...
