沈阳地铁1号线车辆段给排水、水消防工程布局及设计要点

根据沈阳地铁1号线车辆段给排水及消防工程的设计施工及运营的实际情况,总结地处严寒及寒冷地区的沈阳地铁车辆段给排水及消防工程的方案确定及设计重点、难点,关键技术与主要创新点,严寒地区车辆段给排水管道设计应充分考虑当地的气候特点和冻土深度等因素,做好设备管道和构筑物的保温防冻措施,水消防系统应按照全段同一时间一处火灾统一考虑,避免重复建设。

Project Profile and Design Keystones Regarding Water Supply and Drainage & Fire Water System for Rolling Stock Depot of Shenyang Metro Line 1

Based on actual situation of design,construction and operation of the project regarding water supply and drainage as well as fire extinguishing system for the rolling stock depot of Shenyang Metro Line 1,this paper made a summary on this project which is located at severe cold region and cold region, including the project profile,design keystones and difficulties,key technology,and the main innovation. It is suggested in this paper that:( a) during designing the water supply and drainage pipelines for a rolling stock depot at severe cold region,the local climatic features,the depth of frozen soil and so on should be taken into full account,and also the measures of heat preservation and anti-freezing for both the equipment pipelines and structures should be prepared adequately;( b) the fire water system should be comprehensively considered in accordance with the supposing that there is one fire disaster at the same time in the whole depot,so as to avoid duplicated construction.
