摘要
针对极端天气条件下强降水、地面积水对轨道交通系统造成的设备损坏、线路停运等安全问题,通过梳理现有国内关于城市轨道交通防排水设施的建设经验,按车站、区间两部分实行防排水系统的优化设计,综合运用加密泄水孔、安装排水沟闸板密封装置、设置挡水板3项工程措施发挥防排水功能。在此基础上,将两种不同防水板结构在不同水压压力下的受力特征、极限压力值进行比较分析,最终验证连接式铝型材挡水板具有最佳抗压荷载能力。
In view of the safety problems such as equipment damage and line shutdown caused by heavy precipitation and ground water accumulation in extreme weather conditions,through combing the existing domestic construction experience of urban rail transit waterproof and drainage facilities,the optimal design of waterproof and drainage system is implemented according to the station and section,and three engineering measures,namely encrypting drainage holes,installing drain gate sealing devices and setting water baffles,are comprehensively used to exert waterproof and drainage functions.On this basis,the stress characteristics and ultimate pressure values of two different waterproof board structures under different water pressures are compared and analyzed.Finally,it is verified that the connected aluminum waterproof board has the best compressive load capacity.
