Abstract

The invention relates to the field of rail traffic damping, and particularly discloses a shock absorption and settlement prevention subway rail suitable for a tunnel. The subway rail comprises a base and a rail top plate, two rails are fixed on the top of the rail top plate, and two elastic supporting plates are arranged between the base and the top plate; a plurality of groups of symmetrically arranged shock absorption devices are arranged on the base, each shock absorption device comprises a supporting shaft fixed on the base, a sleeve is arranged at the end part of each supporting shaft in a sleeving manner, each sleeve is rotatably connected to the corresponding supporting shaft, a plurality of spiral grooves with the same rotating direction are uniformly distributed in the inner wall of each sleeve, and uniformly distributed arc-shaped protrusions are fixed on the outer side of each sleeve; a transmission shaft extending into the sleeve is fixed to the lower surface of the rail top plate, and a transmission rod is fixed to the periphery of the transmission shaft; and a hydraulic shock absorption box is fixed to the base, a piston is connected into the hydraulic shock absorption box in a sliding mode, and a connecting rod stretching out of the hydraulic shock absorption box and abutting against the arc-shaped protrusions is fixed to the piston. The invention aims to solve the problem of tunnel settlement caused by long-term circulation of the vibration load of the existing subway train.

Description

technical field [0001] The invention relates to the technical field of rail transit shock absorption, and specifically discloses a shock-absorbing anti-subsidence subway track suitable for tunnels. Background technique [0002] With the development of social economy and the advancement of science and technology, various forms of traffic lines (such as subways, light rails, viaducts, etc.) have sprung up like mushrooms after rain. Environmental problems are also increasing. Due to the increasing social conflicts caused by various environmental problems caused by elevated traffic, people are paying more and more attention to the changes in environmental problems caused by rail transit. [0003] Among them, tunnel settlement is one of the most harmful problems. The long-term settlement monitoring of the stations and tunnels of Shanghai Metro Line 1 shows that: when the subway tunnel was completed but not officially opened to traffic, the subway structure was in a floating stat...
