Tunnel with damping track structure

Abstract

A tunnel with a damping track structure comprises a subway tunnel body, a sound control lamp is arranged at the top of the inner wall face of the subway tunnel, reflecting plates are arranged on the two sides of the sound control lamp respectively, a frame plate is arranged on the lower portion of the sound control lamp, a lampshade is arranged in the frame plate, and a reflecting block is arranged at the top of the lampshade. A sound sensor located on the left side of the lampshade is arranged at the bottom of the frame plate and electrically connected with the sound control lamp. Sound absorption pads are arranged on the two sides of the inner wall face of the subway tunnel correspondingly, reflection grooves are formed in the opposite wall faces of the two sound absorption pads correspondingly, a concrete cushion layer is fixedly arranged at the bottom of the inner wall face of the subway tunnel, a supporting plate is fixedly arranged at the top of the concrete cushion layer, and aconcrete sleeper is arranged at the top of the supporting plate. The tunnel is high in practicability, noise generated during train operation can be effectively purified, anxiety of workers can be relieved, vibration of a train to a track can be relieved, and the service life of a track is prolonged.

Description

technical field [0001] The invention relates to a tunnel with a shock-absorbing track structure, which is applied in the technical field of subway tunnels. Background technique [0002] It is well known that the subway is a fast, large-capacity, electric traction rail transit built in the city. The train runs on a fully enclosed line. The lines located in the central urban area are basically located in underground tunnels, and the lines outside the central urban area are generally Located on viaducts or on the ground, the subway is a proprietary, high-density, high-capacity urban rail transit system covering various underground and above-ground road rights in urban areas; most of the existing subway tunnels on the market have the advantages of solid structures, but The lights in the tunnel are not turned on when the subway is running. For the driver or other staff of the subway, it is easy to cause a certain amount of anxiety due to factors such as continuous darkness or sou...

Problems solved by technology

[0002] It is well known that the subway is a fast, large-capacity, electric traction rail transit built in the city. The train runs on a fully enclosed line. The lines located in the central urban area are basically located in underground tunnels, and the lines outside the central urban area are generally Located on viaducts or on the ground, the subway is a proprietary, high-density, high-capacity urban rail transit system covering various underground and above-ground road rights in urban areas; most of the existing subway tunnels on the market have the advantages of solid structures, but The lights in the tunnel are not turned on when the subway is running. For the driver or other staff of the subway, it is easy to cause a certain amount of anxiety due to factors such as continuous darkness or sound during the operation of the subway, and the subway is passing through a section of track. When the pressure caused by the train on the track is released, severe vibration will occur, and long-term use will affect the life of the track. Based on the above problems, a tunnel with a shock-absorbing track structure is proposed
