Small cable trench and construction method thereof

Abstract

The invention provides a small cable trench. The cable trench comprises a cable trench cushion layer positioned below the ground plane, a prefabricated U-shaped cable trench is formed by a prefabricated U-shaped cable trench structural part, cable trench reinforcing steel bars are buried in the cable trench structural part, the tail ends of the cable trench reinforcing steel bars penetrate out ofthe top face of the U-shaped cable trench structural part and are buried in ground concrete 4, the ground concrete and the prefabricated U-shaped cable trench jointly form a trench inner wall, and angle steel is arranged on the edge of the trench. The invention further provides a construction method of the small cable trench. When the prefabricated U-shaped cable trench is prefabricated, trench wall steel bars are reserved; excavating and pouring a concrete cushion layer, installing and adjusting the prefabricated U-shaped cable trench, and arranging an expansion water stop strip at a horizontal construction joint before pouring the ground concrete; the angle steel is fixed on the ground reinforcing steel bars; and finally, the ground concrete is poured and formed. The scheme has the advantages that the efficiency is high; differential settlement of the ground and the cable trench is eliminated; the field use is reduced, and the forming appearance quality of the component can be guaranteed through factory prefabrication.

Description

technical field [0001] The invention belongs to the technical field of engineering construction, and in particular relates to a small cable trench and a construction method thereof, which improves the construction simplicity of the small cable trench. Background technique [0002] With the continuous development of urban infrastructure, many changes have taken place in underground space technology, and the application of cables and pipeline trenches is also more common, which has great advantages over traditional direct buried laying, which can not only meet the requirements of use but also Maintenance and replacement requirements, but with the rapid changes in society and the continuous improvement of people's aesthetic requirements, the requirements for the perception and quality of facilities and detailed structures are getting higher and higher. It still needs to be continuously updated and innovated, which is also a construction quality. difficulty. [0003] Traditiona...
