Problems solved by technology

Because the main material of masonry is solid clay red brick, and because of its production occupies a large amount of cultivated land and consumes energy, it is a non-degradable resource consumption product, which has been gradually limited or even banned by major, medium and small cities. use, and on-site masonry cable troughs, various raw materials are not easy to manage, the construction efficiency is low, the construction period is long, the cost is high, and it also brings certain troubles to the residents near the construction site.

Embodiment Construction

[0041] Such as Figure 1 to Figure 3 The combined cable groove shown is one of the embodiments of the present invention, which includes a plurality of cable supports 2 and a trough body 1 connected head to tail. The cross section of the trough body is U-shaped, and the cable supports are arranged up and down on the On the side wall of the tank body, the heights of the two rows of cable brackets on the two side walls of the tank body correspond to each other.

[0042] see Figure 4 to Figure 6 , the unit length of the tank body 1 is 1000mm, the thick wall reference of the two side walls is 50mm, and the upper part of the two side walls of the tank body 1 is designed as a trapezoidal cross section with a thickness of 100mm and a height of 60mm.

[0043] The groove body 1 of the combined cable groove is composed of the following raw material components mixed in parts by weight:

[0044] R42.5 or R52.5 ordinary Portland cement: 320-400 parts;

[0045] Medium coarse sand: 670-72...

Abstract

The invention discloses a combined cable trench, which comprises a trench body and a bracket. Each side of the trench body is provided with a row of reserved cable bracket holes along the length direction of the trench; the bracket is directly embedded in the reserved hole by an embedding method; and then the reserved bracket hole is blocked with cement mortar on the tail part of the bracket. Compared with the prior art, the combined cable trench ensures more convenient manual operation, and the cable trench body can be industrially produced by using a pre-fabricating form and then assembled on site so as to get rid of the on-site construction without influence on the working environment; the cable trench is assembled with the bracket in one step and then lifted for connection; and the cable trench has the advantages of quick assembling speed, high efficiency, low construction cost, high overall strength and high durability.

Description

technical field [0001] The invention relates to a cable trough for electric power and communication, in particular to a combined cable trough with little impact on the environment of the work site, high assembly speed and high construction efficiency. Background technique [0002] With the acceleration of the construction of modern international cities, urban power lines and communication lines are gradually transferred from the ground to the ground. In order to bury cables, generally there must be a U-shaped cable trench (or cable trench) in the A cable support protrudes from the side wall, and a cover plate is also arranged on the cable trench. [0003] Traditional cable troughs are often built with clay red bricks and cement mortar, and the cable brackets are directly embedded in the wall during masonry. Because the main material of masonry is solid clay red brick, and because of its production occupies a large amount of cultivated land and consumes energy, it is a non-d...
