城市排水系统改造对内涝影响研究
Study on the influence of drainage system reconstruction on urban waterlogging
摘要
Abstract
The research focused on a rainwater pumping station area in the downtown of Tianjin City to assess the current drainage facilities,develop a drainage system model,analyze the current drainage capacity and waterlogging risk,and evaluate the impact of drainage system renovation.Through on-site investigation and analysis of the current pipe network's capacity,it was found that there are issues such as pipe siltation,flow imbalance between large and small pipes,more surface hardening,and low drainage performance.Measures including pipeline dredging,drainage turnaround transformation,LID transformation,and capacity improvement of pumping stations have been implemented to address these problems.These measures have shown effectiveness in reducing waterlogging in the area,particularly improvements to pumping station drainage capacity.Based on these research findings and project construction planning considerations,the drainage management sectors is recommended to proceed with renovation work for the rainwater pumping station area.关键词
