Problems solved by technology

[0006] However, in actual use, the closing force of the anti-flooding door may not be able to break the wire rope. At the same time, due to the installation of too many pulleys, the wire rope is easy to get stuck, resulting in the inability of the moving joint to move, which leads to the failure of the connecting section to fall smoothly.

Abstract

The invention provides a subway tunnel which solves the technical problems that a submerging prevention door in an existing subway tunnel can not be closed, and connecting sections can not fall smoothly. The subway tunnel comprises a tunnel body, a busbar structure used for supplying power for trains and a submerging prevention door capable of closing the tunnel. The tunnel body and the busbar structure are arranged in the tunnel body, the busbar structure comprises a busbar left section, a busbar right section, and a connecting section, wherein the connecting section is arranged between the busbar left section and the busbar right section and used for connection, the connecting section is detachably arranged between the busbar left section and the busbar right section, the submerging prevention door is hinged to the inner wall of the tunnel body, and the connecting section is located at the closing track of the submerging prevention door. The subway tunnel has the advantages that time is saved, efficiency is higher, stability is good, and using is safer.

Description

technical field [0001] The invention relates to a subway tunnel. Background technique [0002] With the rapid development of my country's urban rail transit construction, the form of rigid suspension catenary is widely used. Rigid suspension catenary is a system composed of catenary wires embedded in head-to-tail busbars. It is an important equipment for power supply of electrified railway locomotives and rail transit vehicles. Its quality directly affects the operation of locomotives. [0003] Anti-flood doors are designed in the construction of urban subway tunnels. In the event of war and serious water leakage, it is necessary to quickly close the anti-flood doors and anti-flood doors of the tunnel to ensure the safety of the tunnel and personnel. However, under the blockage of the busbar, the anti-flood door cannot be completely closed, and special personnel need to be sent into the tunnel to remove a section of busbar at the anti-flood door from the entire catenary sys...
