Problems solved by technology

[0003] The purpose of the present invention is to provide a trench high-voltage cable concrete bracket installation and fixing structure and its construction method. To solve the problem of traditional concrete bracket installation, it is necessary to reserve a concrete bracket installation hole in the side wall of the trench in advance, and then carry out two steps after installing the concrete bracket. One-time pouring, long construction time, many and complicated procedures, heavy workload, and the protruding length of the concrete support and the size of the elevation angle cannot be guaranteed

Abstract

A pipe trench high-voltage cable concrete support installing and fixing structure comprises a pipe trench side wall, a concrete support and a fixed frame. One end of a concrete support is pre-embeddedinto the pipe trench side wall, and the other end is supported by the fixed frame arranged on one side of the pipe trench side wall. The concrete support is inclined from the outside of the pipe trench side wall to the inside of the pipe trench side wall. The opening template of the pipe trench side wall is provided with rows of reserved openings, and the reserved openings in each row are spacedapart and are of the same size. The problems of long construction time, many and complex procedures, large workload and incapability to guarantee the extension length and elevation angle of the concrete support caused by the fact that there is a need to reserve a concrete support installation hole in the pipe trench side wall and to carry out second pouring after the installation of the concrete support in traditional concrete support installation are solved.

Description

technical field [0001] The invention relates to the field of cable construction, in particular to a structure for installing and fixing concrete supports for high-voltage cables in pipe trenches and a construction method thereof. Background technique [0002] The construction of the high-voltage cable concrete support needs to reserve holes according to the size of the high-voltage cable concrete support through formwork or other items when pouring the side wall. After the side wall is demolished, it is placed in the concrete support and then poured into the mortar for secondary pouring and fixing. The construction takes a long time. There are many and complicated processes and a large workload. When the bracket holes are reserved, the size of the filler is different, which is inconvenient for the side wall to close the mold and causes the surface of the side wall to be uneven, and the extension length and elevation angle of the concrete bracket cannot be guaranteed.
