- 摘要:
- 深圳市前海—南山排水深隧系统工程是我国首个集旱季污水收集、雨季污染控制及排涝安全保障三种功能于一体的复合型深隧工程。该工程为老城区和中心城区解决排水问题提供了一个新的思路,为发达城市探讨地下空间的综合利用提供了一个鲜活的案例。该工程中污染浓度最高的旱季漏失污水和雨季初小雨在预处理站处理后转输到南山水质净化厂,经强化处理后排放;后续雨水利用隧洞容积进行调蓄,然后转输至南山水质净化厂经一级强化处理后排海;当降雨继续增大,隧洞内水位超过枢纽泵站排涝泵启动水位时开启排涝泵,涝水直接排海。介绍了深隧系统的进水竖井、预处理站、主隧、枢纽泵站等的设计,并总结了工程设计的重点、难点。通过对设计方案的数学模型模拟,得出前海深隧及相关工程建设完成后,可将前海片区的排涝标准提升至50年一遇,并可有效改善大铲湾片区的水环境质量。
- Abstract:
- Qianhai-Nanshan deep tunnel drainage system in Shenzhen is the first complex deep tunnel project in China, which integrates three functions: sewage collection in the dry season, pollution control and urban flood drainage security in the rainy season. The project provides a new option to solve the drainage problem in old cities and central urban areas, and provides a typical case for exploring the comprehensive utilization of underground space in developed cities. In the project, the leaked sewage in the dry season and the initial rainwater in the rainy season with the highest pollution concentration are treated by the pretreatment station and transferred to Nanshan wastewater treatment plant. The effluent is discharged after enhanced treatment. The subsequent rainwater is regulated and stored by the volume of the tunnel, and then transferred to Nanshan wastewater treatment plant and discharged into the sea after primary enhanced treatment. When the rainfall continues to increase and the water level in the tunnel exceeds the starting water level of the drainage pump of the hub pump station, the drainage pump starts and the flood is directly discharged into the sea. The design of the inlet shaft, pretreatment station, main tunnel, hub pumping station of the system were introduced in detail, and the key points and difficulties of the design were summarized. The mathematical model simulation indicated that the drainage standard of Qianhai area will raise to 50-year return period after the completion of the relevant projects, and the water environment quality of Dachanwan Bay Area will be effectively improved.
