A cable trench and its laying process

Abstract

The present application relates to the technical field of cable laying, in particular to a cable trench and its laying process, including a positioning bar, a positioning section and a trench section. Determine the initial installation position of the cable trench through the positioning rod, improve the installation efficiency of the positioning section, reduce the adjustment and positioning of the positioning section installation process; and decompose the cable trench into the positioning section, the first bottom plate, the first side plate, the cover plate and other parts, Effectively reduce the weight of a single hoisting, facilitate the positioning and adjustment of the cable trench laying, and effectively improve the construction efficiency of the cable trench; the first base plate and the positioning section, and the adjacent first base plate are quickly positioned and assembled through the upper convex part and the lower concave platform structure , reducing the steps of measurement and adjustment, effectively improving the laying efficiency of the first bottom slab in the ditch section; the distance between the two second side slabs of the positioning section and the two first side slabs of the ditch section is equal and corresponding, which facilitates the positioning of the first side slab during construction Calibration is conducive to improving the efficiency of assembly and laying of the first side panel.

Description

technical field [0001] The present application relates to the technical field of cable laying, in particular to a cable trench and a laying process thereof. Background technique [0002] The cable trench is an underground pipeline for laying and replacing electric power or telecommunication cable facilities, and it is also an enclosure structure for the cable facilities to be laid. [0003] Traditional cable trenches are mostly constructed by ordinary concrete and steel fiber concrete, which has a long construction period, backward construction technology, and difficult quality control. When the cable trench is damaged, it is difficult to maintain and needs to be poured again, which is easily restricted by the site and natural environment. [0004] The related art discloses a "U"-shaped cable trench prefabricated part, which can effectively shorten the construction period of the cable trench, and the construction is relatively simple. After the "U"-shaped cable trench pref...

AI Technical Summary

Problems solved by technology

[0005] In view of the related technologies mentioned above, the inventor believes that there is a defect that when the prefabricated parts of the cable trench are laid, it is necessary to repeatedly adjust the assembly position of the prefabricated parts, which is time-consuming and laborious, and affects the construction efficiency.
