摘要
提出了一种基于检查井水位在线监测进行雨水系统管道运行状态诊断研究的方法。通过在一定距离管道上下游检查井安装在线液位设备,监测上下游检查井液位,并推算相应管道的充满度,进而通过管道水力学分析推算上下游管道流量。根据上下游管道流量差和所掌握的管道现状拓扑关系,可以判断该段管道上是否存在未知的流量接入或渗漏情况,为进一步通过CCTV等设备检查管道健康状况提供决策支持,减少运行维护成本,并提供异常状况预警的及时性。通过设计流量监测和现场设备安装,经对研究实例所采集数据的初步分析,证明了本方法的有效性。
This paper proposes a method to study the status diagnosis of pipe operation in the rainwater system based on the water level on-line monitoring of manholes.The on-line water level equipment is installed at a certain distance of pipeline from the upstream and downstream of manhole to monitor the water level of the upstream and downstream manholes,and to calculate the corresponding fullness of pipes so that the upstream and downstream pipeline flows are calculated by the hydraulic analysis of pipeline.According to the flow difference of upstream and downstream pipelines and the mastered present topological relation of pipeline,it can be to estimate whether or not there is an unknown flow into the pipeline or leakage situation.In order to further inspect the health status of pipeline through CCTV equipment,the decision support is provided,the operation maintenance cost is decreased,and an early warning of abnormal status is provided.The validity of this method is proved through the design flow monitoring and field equipment instal ation,and the preliminary analysis of the data collected with case study.
