摘要:
国内外均有应用于缓解城市内涝和溢流污染的深隧系统，而深隧系统成功运营的关键技术在于深隧的流量监测，需要根据深隧系统的特点选择合适的流量监测方法。基于技术比选，武汉市大东湖污水深隧系统选择基于超声波互相关原理的超声波流量计作为深隧中流量监测设备，该设备可实现可视化的实时流速监测且达到管道的断面扫描效果，可以在深隧中的400 kPa水压和极端条件下稳定长期工作。采用互相关超声波流量计对深隧断面进行了16层流速测量，结果表明，靠近管壁处的流速远低于平均流速，以平均流速作为深隧不淤流速的判断标准将给深隧运行带来淤积风险。
Abstract:
Deep tunnel system has been applied to alleviate urban waterlogging and overflow pollution both at home and abroad. The key technology for the successful operation of a deep tunnel system depends on the flow monitoring of the deep tunnel, which needs to select the appropriate flow monitoring method according to the characteristics of the deep tunnel system.Through technology comparison, the ultrasonic flowmeter based on the principle of ultrasonic cross-correlation was selected as the flow monitoring equipment in a deep tunnel system in Wuhan Dadong Lake. The equipment realized visualized real-time flow rate monitoring and pipeline cross section scanning, which operated stably for long periods under 400 kPa water pressure and extreme conditions in the deep tunnel. The flow rate of 16 layers in the deep tunnel section was measured by the ultrasonic cross-correlation flowmeter. The results showed that the flow rate near the pipe wall was much lower than the average flow rate. Therefore, taking average rate as the evaluation criterion of non-silting flow rate of deep tunnel will bring silting risk to the operation of the deep tunnel.
