Nested working well and wire arrangement method thereof

Abstract

Provided are a nested working well and a wire arrangement method thereof. The nested working well comprises a top plate, an outer well wall, a well bottom ground and an inner well wall. The well bottom ground is rectangular, the four corners of the rectangle are of right-angle chamfer structures, the outer well wall is vertically arranged and surrounds the well bottom ground by a circle, and the outer well wall comprises four wall faces. The top plate and the top end of the outer well wall are integrally poured and connected to form an in-well space, a plurality of manholes and ventilation holes are formed in the top plate, and an inner well wall is arranged on the well bottom ground to divide the in-well space into an inner well space and an outer well space and form a well-in-well nested structure; a power cable inlet and outlet is designed in the inner wall face of the inner well wall and used for laying a power cable so that the power cable can enter and exit from the inner well space, and a power cable pipe penetrating hole base is arranged on the outer well wall. Therefore, the defects in the prior art can be overcome, the laying effect is improved, laying, overhauling and operation and maintenance work can be conveniently carried out, and the safety performance is improved.

Description

technical field [0001] The invention relates to the technical field of cable laying well structures, in particular to a nested working well and a cable arrangement method thereof. Background technique [0002] With the development of the city, more and more cables are laid in the underground space. This laying technology needs to set up a cable well at a certain distance for cable maintenance and operation and maintenance. Traditional cable wells are designed and manufactured separately for strong electric wells and weak electric wells, which not only consumes a lot of resources, but also does not use the unified management and operation and maintenance of underground cables. For example, the publication number is CN201437729U, which is a cross-shaped intersection of comprehensive pipe trenches. The intersection is similar to the cable well. The intersection is openly connected with four comprehensive pipe trenches in four directions. Normal personnel walk together; however...

Problems solved by technology

Traditional cable wells are designed and manufactured separately for strong electric wells and weak electric wells, which not only consumes a lot of resources, but also does not use the unified management and operation and maintenance of underground cables

For example, the publication number is CN201437729U, which is a cross-shaped intersection of comprehensive pipe trenches. The intersection is similar to the cable well. The intersection is openly connected with four comprehensive pipe trenches in four directions. Normal personnel walk together; however, the above-mentioned technology cannot separate different types of cables in space, and there are shortcomings such as crossing of strong and weak cables, mutual influence, and non-independent operation and maintenance operations.
