Excavating and backfilling system for laying underground 450V polyvinyl chloride insulated control cable

Abstract

The invention relates to an excavating and backfilling system for laying an underground 450V polyvinyl chloride insulated control cable. The excavating and backfilling system comprises a lifting plate, an excavating device and a backfilling device, wherein the excavating device is arranged at the front end of the lifting plate, and the backfilling device is arranged at the rear end of the liftingplate. The excavating and backfilling system has the advantages that the problems that in the existing cable direct burying process, a worker needs to perform ditching and backfilling rolling on soil,in the ditching process, the worker needs to perform ditching by means of a tool, potential safety hazards occurs due to back injuries caused due to the fact that the worker bends over to work for along term, the later-stage backfilling effect is influenced due to the fact that the sizes of soil blocks excavated manually are not uniform, meanwhile, after manual ditching, the soil treatment is complicated, in the backfilling process, the excavated soil needs to be subjected to manual backfilling and then needs to be beat and pressed manually, the process is tedious, due to the fact that the excavated soil is caked differently, the soil is not compact in the manual pressing process, the time consumed by the laying process is long, the labor intensity is high, and the efficiency is low canbe solved, and the functions of automatically carrying out excavating and backfilling rolling on the soil in the laying process of the underground cable can be achieved.

Description

technical field [0001] The invention relates to the technical field of laying buried cables, in particular to an excavation and backfill system for laying buried 450V polyvinyl chloride insulated control cables. Background technique [0002] The commonly used types of existing power cables include 10KV overhead insulated cables, parallel set overhead insulated cables, 0.6KV polyvinyl chloride insulated power cables, 1KV polyvinyl chloride insulated power cables, 35KV cross-linked polyvinyl chloride insulated power cables, 450V polyvinyl chloride insulated power cables, Vinyl insulated control cables, 750V polyvinyl chloride insulated control cables and communication cables, etc., the penetration rate of buried cables is very large now, among which 450V polyvinyl chloride insulated control cables are most commonly installed underground, due to the urban population Many, high land utilization rate, direct buried cables are mostly used in cities, buried cables save materials an...

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides an excavation and backfill system for laying buried 450V polyvinyl chloride insulated control cables, which can solve the cumbersome process that requires workers to dig trenches and backfill and roll soil in the process of laying existing direct-buried cables It is complicated. When digging trenches, personnel need to use tools to dig trenches. Long-term bending over work will cause back injuries and cause safety hazards. Manual trenching is uneven and affects later work. The size of manually excavated soil blocks affects the effect of later backfilling. At the same time, It is cumbersome to deal with the soil after manual trenching. When backfilling the soil, it is necessary to manually backfill the excavated soil and then beat and press it. The process is cumbersome. Due to the uneven agglomeration of the excavated soil, the manual pressing is not compact, and the laying process takes a long time. , high labor intensity and low efficiency, it can realize the function of automatic excavation and backfill rolling soil when laying buried cables, automatic trench digging and backfill, trench leveling, automatic cutting of soil, automatic soil transportation, automatic The backfill soil loosens the soil, rolling compactly, without manual on-site operation, which ensures the safety of personnel, takes a short time, and has the advantages of simple operation, low labor intensity and high work efficiency.
