排水管道水力冲洗设施在综合管廊中的应用
- Title:
- Application of Drainage Pipe Hydraulic Flushing Facility in the Utility Tunnel
- 摘要:
- 综合管廊普遍埋深较大，为解决综合管廊中重力流污水管、雨水舱在运行时淤积堵塞清掏维护难度大的问题，提出在污水管道中采用全自动水力冲洗、能耗小、效率高的管道拦蓄盾自动冲洗系统，在雨水管道中采用真空冲洗系统,便于管廊的运营维护管理。介绍了两个系统的工作原理、设备组成及安装、运行控制要求，并给出了实际工程应用案例，总结了两个系统在重力流管渠设计中的位置设定、设备选型、详图设计、运行控制、工程措施、主要经济指标及后期运行的注意事项，为综合管廊重力流污水管、雨水舱的设计和运行提供参考。
- Abstract:
- The buried depth of the utility tunnel is generally large. Full-automatic hydraulic flushing, low energy consumption and high efficiency channel flushing gate system in sewage pipes, and vacuum flushing system in rainwater pipes are proposed to solve the problem of cleaning and maintaining the gravity flow sewage pipes and rainwater tanks in the utility tunnel, and to facilitate the operation and maintenance management of the utility tunnel. Working principle, equipment composition, installation and operation control requirements of the two systems, which combined with practical engineering application cases are introduced. The location setting, equipment selection, detail design, operation control, engineering measures, main economic indicators and matters needing attention in the later operation of the two systems in the gravity flow pipe channel design are summarized, which will provide a reference for the design and operation of the gravity flow sewage pipes and rainwater tanks in the utility tunnel.
