深层排水调蓄隧道系统集约化布置关键技术研究

Research on Key Intensive Layout Technology of Deep Drainage Storage Tunnel

针对上海苏州河段深层排水调蓄管道系统工程面临的用地紧张问题,从系统总体集约化布局与综合设施集约化布置两个方面,依托苏州河深隧试验段工程,研究了深层调蓄隧道集约化布置技术,为完善城市排水防涝体系、实现径流污染控制、提升城市深层地下空间综合开发水平提供了技术支撑。研究表明:主隧综合设施的间距受用地条件和隧道运行安全影响,可适当放大至2~3 km;综合设施布置宜采用竖向开发以充分利用地下空间;深隧预处理方式宜考虑多点拦截方式。

Aiming at the problems of land shortage in Shanghai Suzhou Creek Deep Drainage Storage Pipe System Project,from two aspects of the overall intensive layout of the system and the intensive layout of integrated facilities,and relying on Suzhou Creek Deep Tunnel Test Section Project,the intensive layout technology of deep storage tunnel is studied in order to provide the technical support for perfecting the urban drainage waterlogging prevention system,realizing the runoff pollution control and promoting the comprehensive development level of urban deep underground space.The study results show that the spacing of the integrated facilities in the main tunnel is affected by the land use conditions and tunnel operation safety.The spacing can be appropriately enlarged to 2~3 km.The vertical development should be adopted for the layout of the integrated facilities so as fully to utilize the underground space.The multi-point interception mode should be considered for the deep tunnel pre-treatment mode.
