Fabricated cable trench

Abstract

The invention discloses a fabricated cable trench, which comprises a left stand plate and a right stand plate. A cable cavity is formed between the left stand plate and the right stand plate, and thebottom of the left stand plate is connected with the bottom of the right stand plate through a plurality of connecting beams. According to the fabricated cable trench, a bottom plate of an original cable trench is omitted, so that a slope structure for drainage is omitted, the structure is quite simple, material consumption during manufacturing is lower, the structure is simplified, the weight islower, later transportation and assembling difficulty is lowered, and the fabricated cable trench can be produced on a large scale in a standardized mode in factories. Additionally, since the bottom is hollowed, seeping rainwater is directly discharged from the bottom, no other drainage equipment is required, matching equipment can be reduced, and the cost is lowered. The fabricated cable trench is especially suitable for gravel and sandy areas with good water permeability, such as the northwest area of China.

Description

technical field [0001] The invention relates to the technical field of electric power engineering construction, in particular to an assembled cable trench. Background technique [0002] In the construction of substations, brick cable trenches and cast-in-situ concrete cable trenches are generally used in the construction of cable trenches. The construction period on site is relatively long, and construction is subject to many constraints in special environments such as low temperature and rain, expansion projects, and short construction periods. The prefabricated concrete cable trench adopts concrete and steel formwork construction technology. The cable trench structure is prefabricated in sections in the factory, and then assembled on site, so that the construction of the substation starts from the traditional civil engineering design and construction mode to "design standardization, The transformation of the mode of "factory processing, mechanization of installation, and p...

AI Technical Summary

Problems solved by technology

Traditional cable trenches such as figure 1 As shown, the cross-section of the cable trench is concave. After construction, cover the top with a cover plate, and the entire cable trench will be closed. When rainwater seeps in, it will accumulate inside the cable trench. It is necessary to design a drainage slope at the bottom of the cable trench, and the substation should also have The corresponding pumping facilities increase the complexity of the structure and increase the number of equipment

At the same time, wind and sand in Northwest China tend to accumulate in a small amount in cable trenches, making it difficult to clean up
