WASHING SYSTEM AND METHOD OF TUNNEL FOR SUBWAY

摘要

PURPOSE: A washing system and a method for a tunnel of a subway are provided to wash walls of the tunnel by water of an injection nozzle supplied with a ventilated hole in high pressure from a group of washing water supply vehicles on the ground. CONSTITUTION: A washing system for a tunnel(3) of a subway comprises a group of washing water supply vehicles(1); a washing water supply pipe(4); a washing water distributor(5) and a washing hose(6). The group of washing water supply vehicles comprises a high pressure supply vehicle(10) of washing water and storing vehicles(11) of washing water. The washing water supply pipe is connected to the high pressure supply vehicle of washing water and inserted to an entrance of a subway station or a ventilated hole(2) to connect a passage for supplying washing water from the ground to the tunnel. The washing water distributor is connected to an end of the washing water supply pipe of the tunnel to distribute washing water into several branches. The washing hose is connected to the washing water distributor to inject washing water in high pressure to an inner wall of the tunnel by an operator(300,400). Thereby, working efficiency is improved by injecting washing water supplied from the ground rapidly without moving a water tank, and fine dusts are removed by high pressure washing water.
