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.

Description

technical field

[0001] The invention relates to a high-voltage cable laying support for tunnel construction. Background technique

[0002] In engineering construction, electricity is needed for both 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 high-voltage cables with insulating layers have to be used for power transmission, so cable laying is essential One link; especially in underground projects such as tunnel construction, the construction period is long, the lighting and power requirements are large, and the power consumption is large; for the normal construction of tunnel construction, cable laying must be carried out. 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 ...
