Problems solved by technology

[0002]During engineering construction, electricity is required for lighting and power; however, due to site and environmental constraints, the elevated bare-wire high-voltage lines commonly used in the field cannot be used, and belts have to be used. The high-voltage cable of the insulating layer transmits electricity, so cable laying is an indispensable link; especially in underground projects such as tunnel construction, the construction period is long, the demand for lighting and power is large, and the power consumption is large; for the normal construction of tunnel construction , it is necessary to carry out cable laying
However, in the cable laying of the existing tunnel construction, there is a certain temporary nature of construction electricity, and the construction site is often changed, resulting in unsatisfactory standardization of high-voltage cable laying, serious random pulling, and messy cable bending. The smoothness is poor, and there are even phenomena such as high-voltage cables directly on the steel bar head and cable entanglement, which pose serious safety hazards
At the same time, due to the poor smoothness of the cable and the problem of winding, the length of the cable used will increase, the construction cost will be high, and the power loss on the cable will be large
Therefore, in the existing high-voltage cable laying for tunnel construction, there are problems such as poor cable smoothness, unsatisfactory safety of cable use, high construction cost and large power loss on the cable.

Abstract

The invention discloses a high voltage cable laying support used for tunnel construction. The high voltage cable laying support comprises two supporting steel bars which are horizontally arranged. Equilateral angle steel is connected between the two supporting steel bars. One side of equilateral angle steel is fixedly connected with the end parts of the two supporting steel bars. A cable hook is connected on one side of equilateral angle steel via a bolt. Equilateral angle steel is connected and fixed by arrangement of two supporting steel bars, and then the cable hook is connected via equilateral angle steel and a high voltage cable is laid via the cable hook; and a reinforcing rib is also arranged at the bottom part of the cable hook so that structural strength of the cable hook is enhanced, laying of the high voltage cable with high weight is facilitated and laying stability of the high voltage cable is enhanced. Smooth degree and use safety of the cable can be enhanced by the high voltage cable laying support and use is convenient, and the high voltage cable laying support also has advantages of simple structure, low construction cost, low electric energy loss, high structural strength and great cable laying stability.
