Design In Water Supply & Drainage System For Metro & Maglev Project And Research In Fire-fighting System For Tunnel

In this article, the design of water supply&drainage system and fire extinguishing system in metro project and maglev project are introduced,This article, based on the features of Metro project and road tunnel, analyses the causes of frequent fire break outs and hazardous nature of a fire, and at the same time, describes fire fighting measures for them, with emphasis on analyses and comparisons among various systems of fire extinguishing on Metro lines and road tunnels.The main fire extinguishing system for road tunnel and Metro lines include:Hydrant systemSprinkler systemWater spray extinguishing systemFoam systemFoam-water mist systemGas extinguishing systemWater mist fire extinguishing systemThis article analyses their respective defects and merits, and points out the adaptability to each project.Maglev project is a significant part of metro project.In this article,the Environmental Assessment of maglev project are argued,and the environmental security of Maglev project are proved.
