Construction method of mechanical and electrical installation for the entrance and exit of the long ramp of the subway

Abstract

The invention relates to a subway construction process, in particular to a mechanical and electrical installation construction method for the entrance and the exit of a long heavy grade of a subway. The construction method adopts a train guide rail operation principle, a simple guide rail, a power system, a brake system and transportation equipment are arranged to construct a long heavy grade guide rail material and equipment transportation system, and the problem of low material transportation efficiency is solved. A triangle stability principle is applied, a measurement of preventing forwardslippage and overturn is taken on the basis of the characteristic of the long heavy grade, an operation platform is erected in a staged and graded manner, and the safety of operators is ensured. A BIM technology is adopted as a guide in the construction process, the bracket direction is changed, the quantity of inclined fixed brackets is increased, a traditional bracket is improved, the practicality and the operability are improved, and the stability of an electromechanical system is enhanced. A large-section cable transportation system is self-made by combining a pulley block with a windlass, and the pull-up problem of a large-section cable is solved; and bunched rigid cables are arranged one by one by a self-made F-type wrench, so that the problem of jumbled arrangement of the bunched rigid cables is solved.

Description

technical field [0001] The invention relates to a subway construction technology, in particular to a construction method for the electromechanical installation of the entrance and exit of the long ramp of the subway. Background technique [0002] The subway is a fast and large-capacity urban rail transit mode that is gradually developed along the surface railway system, and its lines are usually laid in underground tunnels. With the rapid development of rail transit and the popularity of urban subways, the interaction and overlap of subways has also increased, resulting in an increase in the depth of transfer stations. [0003] With the deepening of the subway station, the technical defects of the mechanical and electrical installation and construction related to the use function of the entrance and exit of the long ramp of the subway are gradually exposed. At present, the electromechanical installation and construction technology of the entrance and exit of the long ramp o...
