Problems solved by technology

[0020] The technical problem to be solved by the present invention is to provide a single-track railway floor-type lining and its drainage system structure using a traffic avoidance to set up an inspection well, so as to reduce or even eliminate the effect of groundwater on the bottom structure of the tunnel lining, and effectively solve the problem of karst or groundwater development. Inverted arch deformation or tunnel bottom structure cracking and damage in regional tunnels, it is convenient to check and repair the drainage system to ensure the stability and safety of tunnel construction and operation

Embodiment Construction

[0044]The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0045] refer to Figure 1 to Figure 10 , a single-track railway floor lining and its drainage system structure using a car avoidance to set an inspection well in the present invention, including an arch wall primary support structure 10, an arch wall secondary lining structure 40, an arch wall range waterproof layer 20 and avoidance Car hole A, and drainage system. The bottom of the secondary lining structure 40 of the arch wall is provided with a floor structure 41, and the two ends of the floor structure 41 are consolidated with the two ends of the secondary lining 40 of the arch wall, and axils are added inside the joint. The floor structure 41 does not need to be filled with concrete, which effectively avoids the destruction of the track structure caused by groundwater entering the gap between the inverted arch and the inverted arch filling gap th...

Abstract

The invention provides a single-line railway bottom board type lining utilizing a refuge hole for arranging an inspection well and a drainage system construction of the said lining, aims to reduce andeven eliminate influence on a bottom structure of a tunnel lining by underground water, solves problems of floating deformation of inverted arches of tunnels or cracking damage of tunnel bottom structures in karst or underground water areas, is capable of performing checking and maintenance on a drainage system and ensuring stability and safety of tunnel construction and operation. A bottom boardstructure is arranged on the bottom part of an arch wall secondary lining structure. Two ends of the bottom board structure are fixedly connected to two ends of the arch wall secondary lining and haunching is performed on the inner sides of the connection parts. A longitudinal through central water trench is arranged along the longitudinal central axis below the bottom board structure. The inspection well is arranged in the refuge hole. Transverse connection channels connect the central water trench with the inspection well. The drainage system includes an arch wall range drainage system, a tunnel bottom drainage system and an in-tunnel drainage system communicating with the central water trench.

Description

technical field [0001] The invention relates to a tunnel lining and a drainage system structure, in particular to a single-track railway tunnel lining and its waterproof and drainage system structure used in areas with developed groundwater or karst areas. Background technique [0002] Since the beginning of the 21st century, my country's railway construction has developed rapidly, especially in the southwest mountainous area, where karst is developed, and the development of the line is restricted by various factors such as large curve radius and complex topographic and geological conditions, and the scale of karst tunnels has increased rapidly. Due to the complexity, diversity, and irregularity of karst and karst water development, the risks of building large karst tunnels, especially their operation, are getting higher and higher. [0003] According to the investigation, the existing line water damage is mainly divided into two categories: [0004] (1) The inverted arch i...
