Integrated prefabricated cable trench and cable well

Abstract

The invention belongs to the technical field of electric power facilities, and provides an integrated prefabricated assembly type cable trench and cable well, and the cable trench comprises a cable trench which comprises a plurality of pipe joint units, each pipe joint unit comprises two first side plates, and the two sides of each first side plate are provided with first connecting assemblies used for connecting the pipe joint units; the cable well comprises a side frame structure, cable trench holes are formed in the periphery of the side frame structure, and a plurality of second connecting assemblies used for being connected with cable trenches are arranged on the left side and the right side of each cable trench hole. Compared with the prior art, the prefabricated cable trench and the prefabricated cable well are adopted, so that 100% assembly is realized, and the defects of high construction cost, long construction period, high maintenance cost and great environmental influence of cast-in-place are overcome; and the convenience of connection between the cable well and the cable trench and between the pipe joint units of the cable well is realized through the second connecting assembly and the first connecting assembly, and the problem of connection damage of the cable trench crossing the road under the action of automobile impact and fatigue load is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of electric power facilities, and in particular relates to an integrated prefabricated cable trench and a cable well. Background technique [0002] The cable well is used in conjunction with underground pipelines for long-distance buried power supply. It is used for the installation and maintenance of cables for lines, which is convenient for construction and maintenance of cables. The existing cable well production is basically on-site production, and the main content is on-site trench excavation and pouring-reinforcement binding-formwork support-concrete pouring-concrete curing-formwork removal-earthwork backfilling. The length of the construction period is mainly reflected in the process from steel bar binding to formwork removal. During this process, a lot of labor is required and the work efficiency is low. This process is also a critical period that affects the quality of the cable well. On-site bindin...

AI Technical Summary

Problems solved by technology

[0004]So the existing prefabricated cable trench system only has the trench body, and the cable well is still cast-in-place, lacking the prefabricated cable well and the integrated connection of the trench-well

In addition, the cable trench often needs to cross the road. Under the impact and fatigue load of the car, the joint between the trenches of the existing assembled cable trench is prone to shear failure
