Overhaul trench drainage ditch system with one well and two ditches and used for railway in city area

Abstract

The invention discloses an overhaul trench drainage ditch system with one well and two ditches and used for a railway in a city area. The overhaul trench drainage ditch system with one well and two ditches and used for the railway in the city area is characterized by comprising lateral drainage ditches (2), a pre-drainage transversal drainage pipe (3) and a water collection well (4), wherein the water collection well (4) is arranged between overhaul trenches (1) at the two transversal sides; the lateral drainage ditches (2) are arranged at one transversal side close to the water collection well (4), of the overhaul trenches (1) separately; and the lateral drainage ditches (2) communicate with the water collection well (4) through the pre-drainage transversal drainage pipe (3) separately, so that drainage for accumulated water in the overhaul trenches (1) is realized. The lateral drainage ditches (2) are full-length longitudinal slopes, and the longitudinal sections are W-shaped. According to the overhaul trench drainage ditch system, the problem of influence on the polling working of personnel due to uneven laying for cover plates of the drainage ditches in the actual engineering is solved by reducing the section dimensions of the lateral drainage ditches, cancelling the cover plates of the drainage ditches, and omitting the later-period maintenance expense for the cover platesof the drainage ditches.

Description

technical field [0001] The invention belongs to the technical field of urban railway maintenance trenches, and more specifically relates to a maintenance trench drainage system with one well and two trenches for urban railways. Background technique [0002] The inspection of the trench in the urban railway inspection library provides conditions for personnel to repair the bottom of the vehicle. The urban railway maintenance trench adopts a ditch bottom elevation of -700mm relative to the ground, creating a clearance height of about 1.7m between the bottom of the urban EMU and the maintenance trench The maintenance space, the space between the maintenance trench and the bottom of the car body can meet the needs of the maintenance personnel for maintenance operations, and provide convenience for the maintenance personnel to walk and perform maintenance. [0003] However, the maintenance trench is lower than the ground of the maintenance garage. Therefore, the maintenance trenc...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the above defects or improvement needs of the prior art, the present invention provides a maintenance ditch drainage system with one well and two ditches for urban railways. By reducing the cross-sectional size of the lateral drainage ditch, the drainage ditch cover plate is eliminated, and the later drainage ditch cover is eliminated. The cost of plate maintenance is reduced, which solves the problem of uneven laying of drainage ditch cover plates in actual projects, which affects personnel inspection operations
