Power pipeline optical cable laying auxiliary device and fabrication and construction method thereof

Abstract

The invention discloses a power pipeline optical cable laying auxiliary device and fabrication and construction methods thereof. The power pipeline optical cable laying auxiliary device comprises a cylinder of which the middle portion is cylindrical and two ends are arc-shaped tip end head portions respectively. An intermediate pipe is axially arranged in the cylinder in the central axis. One end portion of the intermediate pipe is connected on the arc-shaped tip end head portion inner wall of one end of the cylinder, and the other end of the intermediate pipe is fixed on the arc-shaped tip end head portion of the other end of the cylinder and extended to the outside. The end portion which is extended to the outside is provided with optical cable connection holes transversely. The fabrication method comprises the following steps: a) two half cylinders are fabricated; and b) the two half cylinders are connected to form the whole cylinder structure. The construction method comprises the following steps: a) the auxiliary device is installed on the head of a pipe pass-through machine and fixed; b) the pass-through rod of the auxiliary device is guided into the cable pipe hole; c) the auxiliary device passes through successfully and is floated on the surface of water; d) and an optical cable is fixed on the other end of the pipe pass-through machine and pulled out from the pipeline through the pipe pass-through machine so as to complete the optical cable laying process.

Description

Technical field [0001] The invention relates to an auxiliary device for laying optical cables of electric power pipelines and a manufacturing and construction method thereof, belonging to the technical field of optical cable laying of electric power pipelines. Background technique [0002] In recent years, the construction of power system pipeline optical cables has been very rapid. Due to the limitation of pipeline resources, a large number of urban optical cables are laid in the same tube hole with 10kV cables because there is no special communication tube hole. Since there are many gaps between the 10kV cable with a large diameter that has been laid before and the pipe wall, the pipe threader often enters these gaps when the optical cable is laid and is obstructed by the suppression of the cable, making the laying very difficult. At the same time, the two ends of the power pipeline are upturned, and the rods are more likely to enter the dead corners, causing "jamming". Theref...

AI Technical Summary

Problems solved by technology

Because there are many gaps between the 10kV cable with a thick cable diameter that has been laid before and the pipe wall, the pipe threading machine often enters these gaps when laying the optical cable and is hindered by the cable, making the laying very difficult.

At the same time, the two ends of the power pipeline are upturned, and it is easier to enter the dead angle when passing through the rod, causing "stuck"

Therefore, it is often time-consuming and laborious to lay optical cables in the pipe holes with cables, and it is even impossible to communicate.
