Mounting structure and method for drainage grid of transverse drain ditch

Abstract

The invention discloses a mounting structure for a drainage grid of a transverse drain ditch. The mounting structure comprises a pavement surface layer, a backfilling layer, a structural bottom plate,a first pouring layer, a second pouring layer and the drainage grid, wherein the first pouring layer is located within the structural range of the two sides having the same width with the transversedrain ditch, and in the longitudinal direction, the first pouring layer is poured to 18-22 cm below the pavement designed elevation; and the drainage grid is arranged at the first pouring layer, inserted ribs are arranged on the two sides of the drainage grid correspondingly, the drainage grid and the first pouring layer are fixedly connected together through the inserted ribs, the inserted ribs are connected with an inserted rib net of the second pouring layer, and the inserted rib net is fixedly connected with a main body rebar. The mounting structure is simple, convenient to construct, reasonable in arrangement, and convenient to operate and maintain, and maintenance management of the drainage grid in a city municipal-service tunnel is effectively perfected.

Description

technical field [0001] The invention relates to the field of urban municipal tunnels, in particular to an installation structure and an installation method of a cross-cut ditch drainage grate. Background technique [0002] With the development of the economy, in order to alleviate the problem of urban traffic congestion, and at the same time to avoid the demolition and environmental protection problems caused by bridge construction, many cities build urban municipal tunnels. Generally, urban municipal tunnels are built in the central area of ​​the city, mainly for passenger traffic. The passenger flow is relatively large. In order to prevent the rainwater and waste water outside the tunnel from entering the tunnel, it is necessary to set up a cross-cutting ditch on the road. The width of the cross-cutting ditch ranges from 300-600mm. [0003] According to previous engineering cases, the drainage grate of the cross-cut ditch has various materials and various fixed installatio...

AI Technical Summary

Problems solved by technology

[0003] According to previous engineering cases, the drainage grate of the cross-cut ditch has various materials and various fixed installation methods, but there are problems such as easy deformation of the drainage grate, short service life, easy loosening of the connection between the grate and the road structure, broken surrounding structures, and poor effect of secondary maintenance and replacement And other situations, not only affect the comfort of driving, but also have great potential safety hazards
