A cable duct backfill device

Abstract

The invention provides a cable duct backfilling device, which belongs to the technical field of auxiliary devices for electric power construction. The technical scheme is as follows: comprising a car board, rear wheels are arranged on both sides of the rear end of the car board through a rotating shaft, the rear wheels are connected with the power device through a transmission mechanism, and a front-end middle position of the car board is provided with a pass through the upper and lower parts. The front wheel controlled by the adjustment mechanism; the car board is provided with a discharge port, the car board is provided with a mesh sieve plate covering the discharge port, and both ends of the mesh screen plate are fixedly provided with The baffle plate is fixed, side plates are arranged on both sides of the car plate, the lower part of the side plate is provided with a feeding port, and the outer side of the feeding port is provided with a feeding mechanism, and the car plate is below and located at the A tamping mechanism is arranged between the discharge port and the front wheel. The beneficial effects of the invention are as follows: while the fine soil or fine sand is compacted, the soil obtained from trenching is laid, so as to shorten the time for backfilling the cable pipeline and improve the work efficiency.

Description

technical field [0001] The invention relates to the technical field of auxiliary devices for electric power construction, in particular to a backfilling device for cable ducts. Background technique [0002] Cable laying refers to the process of laying and installing cables along a surveyed route to form a cable route. According to the occasion of use, it can be divided into several laying methods such as overhead, underground (pipeline and direct burial), underwater, wall and tunnel. Among them, underground direct burial is the most common laying method. Underground direct burial is in accordance with the requirements of the specification. After the direct buried cable trench is dug, the sundries in the trench are removed, pipes are arranged in the trench, and cables are laid in the pipes. , After the cable is laid, 10cm of fine sand or fine soil should be backfilled. After laying the soil obtained by digging trenches, bricks or concrete slabs need to be laid later accordin...

AI Technical Summary

Problems solved by technology

In actual work, 10cm-thick fine sand or fine soil must be manually compacted before laying the soil obtained from trenching. Generally, manual backfilling is required, and sometimes large stones or plastic products in the soil need to be picked out. Finally, tamping is carried out by large-scale tamping equipment, the whole working procedure is complicated and the efficiency is low
