全自动运行线路隧道区间水位监测设置及积水处置方案

Tunnel Interval Water-level Monitoring Setting and Waterlogging Drainage Plan for FAO Line

全自动运行线路对隧道区间水位监测及积水处置提出了更高的要求,需针对全自动运行线路的特点和隧道区间水位监测需求,提出水位监测设置及积水处置方案。分析了隧道区间水位监测需求及非全自动运行线路的水位监测设置方案特点,介绍了全自动运行线路隧道出入口和区间坡度最低点的水位监测设置方案,以及积水处置时排水系统、BAS(环境与设备监控系统)、ISCS(综合监控系统)、信号系统和通信系统等专业系统的联动策略。结合全自动运行线路特点的隧道区间水位监测设置方案,能满足发生积水时的运营需求;积水情况下,根据不同水位监测点及不同水位高度而设计的各系统之间差异化联动方案,能够实现隧道积水预警预报及应急处理。

The FAO(fully automatic operation)line has raised higher requirements for water-level monitoring and waterlogging drainage in tunnel interval.It is necessary to propose a water-level monitoring setting and waterlogging drainage plan that takes into account the FAO line characteristics and tunnel interval water-level monitoring requirements.The tunnel interval water-level monitoring requirements and the characteristics of non-FAO line water-level monitoring setting plan are analyzed and the water-level monitoring setting plans for FAO line tunnel entry/exit and interval slope lowest point are introduced,as well as linkage strategies of professional systems including the drainage system,BAS(building automatic system),ISCS(integrated supervisory and control system),signaling system,and communication system during waterlogging drainage.The proposed tunnel interval water-level monitoring setting plan based on FAO line characteristics can meet the operational needs in case of waterlogging;under this circumstance,the differentiated linkage strategies among the systems designed based on different water-level monitoring points and different water-level heights can realize tunnel waterlogging early-warning and emergency response.
