Cable trench structure and cable laying method

Abstract

The invention provides a cable trench structure and a cable laying method, relates to the technical field of electric power facilities and installation technologies thereof, and aims to solve the problem that a cable is inconvenient to lay due to the fact that a worker needs to enter a foundation pit for pulling the cable in an existing cable laying process. The cable trench structure comprises atrench body, a cover plate and multiple rows of cable supports arranged on the side walls of the trench body, wherein each cable support comprises a laying rod on the lower side and a pressing rod onthe upper side; the side walls of the trench body are vertically provided with sliding grooves; the upper ends of the sliding grooves are provided with openings; one ends of the laying rod and the pressing rod are provided with sliding blocks; and the sliding blocks are arranged in the sliding grooves in a sliding mode. The cable laying method comprises the steps of excavating the foundation pit;installing the trench body; installing the cable supports and alternate rolling supports; laying the cable layer by layer; installing studs; installing the cover plate; refilling the foundation pit; and finishing the laying. The cable trench structure has the beneficial effects that the cable can be laid outside the foundation pit conveniently by the worker.

Description

technical field [0001] The invention relates to the technical field of electric facilities and installation technology thereof, in particular to a cable trench structure and a cable laying method. Background technique [0002] Cable trench is an underground pipeline for laying and replacing electric power or telecommunication cable facilities, and it is also an enclosure structure for laid cable facilities. There are rectangular, circular, arched and other pipeline structure forms. The cable trench structure in the prior art is generally There is a channel with a cover plate, and a cable bracket for laying cables is arranged in the channel. [0003] The usual method of cable laying is to excavate the foundation pit first, then put the cable trench into the foundation pit, and then put the cable on the cable bracket in the cable trench, because the cable bracket is fixed on the inner wall of the cable trench Yes, when placing cables, construction personnel need to enter the ...

AI Technical Summary

Problems solved by technology

[0005] The cable support in the cable trench structure is fixedly connected to the side baffle. When the cable support has multiple rows, it is difficult to lay the electricity on the lower cable support, and it is necessary for personnel to enter the foundation pit to pull the cable, which makes the cable laying inconvenient.
