Abstract

The invention discloses a distribution line cable trench concave prefabricated part that comprises at least two groups of cable concave grooves; a concave groove is formed in the cable concave groove;the cable concave groove comprises a cable concave groove body; the two ends of the cable concave groove body are provided with interface ends, wherein one interface end is a concave fracture, the other is a convex strip opening; the concave fracture of the previous cable concave groove and the convex strip opening of the next cable concave groove are connected in an inserted mode; water seepageholes are formed in the side walls of the cable concave grooves, a trench cover plate is arranged above the tops of the cable concave grooves, and the trench cover plate is a flat plate covering the upper portions of the cable concave grooves. The invention further relates to a mold and a manufacturing method of the distribution line cable trench concave prefabricated part. The construction work amount can be greatly reduced, the construction period is shortened, the construction efficiency and the construction quality are improved, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a concave prefabricated component of a distribution line cable groove, a component mold and a preparation method 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. There are rectangular, circular, arched and other pipeline structures. [0003] The layout of cable trenches in power plants and substations is related to field equipment and terrain conditions, but both indoor and outdoor cable trenches generally have the following characteristics: [0004] (1) The cable trench is a trench with a cover plate, and the cover plate must be uncovered when laying and maintaining cables, which is very cumbersome and inconvenient, and dirt and water are easy to accumulate in the trench.
