Multifunctional cable trench

Abstract

The invention relates to the technical field of the transformer substation and provides a multifunctional cable trench that is provided for solving a problem of the collision between the drain pipe and the foundation of the building and enables the drain pipe length to be saved and the corresponding building project amount to be reduced. The multifunctional cable trench comprises a lower drainage channel formed by masonry at the bottom, a side drain well being arranged beside the lower drainage channel and being communicated with the lower drainage channel, and an upper cable trench being arranged above the lower drainage channel and being communicated with the lower drainage channel. A cable support frame for installing a cable is arranged inside the cable trench; a cable trench cover plate is arranged at the top of the cable trench; and the cable trench and the lower drainage channel are communicated by cable trench drain holes. The multifunctional cable trench has the drainage function; the novel cable trench drainage function and the drainage pipe arrangement at the field of the station are taken into consideration; the drainage pipe arrangement is optimized; the field drainage pipe length is saved; and the collision between the drainage pipe and the building foundation can be eliminated. The building project load can be reduced and the construction costs can be saved.

Description

technical field [0001] The invention belongs to the technical field of substations, in particular to an outdoor multifunctional cable trench structure of a substation. Background technique [0002] In recent years, the State Grid Corporation of China has required the construction of intelligent, environmentally friendly, prefabricated substations. Among them, there are strict requirements on the area occupied by substations. The total area of ​​the substation must not exceed the standard design, and the area occupied should be minimized to save non-renewable resources --- land. [0003] When laying out the general layout of the substation, in order to meet the document requirements of the State Grid Corporation, the electrical profession minimized the land occupation. When civil engineering majors design station area drainage, rainwater inspection wells and drainage pipes often collide with the foundation of buildings and structures, and sometimes it is difficult to solve th...
