城市下凹桥区内涝系统治理

Waterlogging System Control in Urban Sinking Bridge Area

摘要:

下凹桥区等低洼区域排水问题，不仅会使其所在环线交通中断，还会影响周边道路及其它环线的通行，影响人民正常生活，并给国家和人民的财产造成了重大损失。以内涝频发并受到广泛关注的城市下凹桥区为研究对象，在研究过程中通过校核城市下凹桥区现状排水能力、诊断下凹桥区内涝形成原因，分析下凹桥区排水设施改造方案，提出了针对下凹式立交桥积滞水问题的预防建议和解决方案。

Abstract:

The drainage problem in low-lying areas such as the sinking bridge area will not only interrupt the traffic of the ring line at its place, but also affect the traffic of surrounding roads and other ring lines, which will affect the normal life of the people and cause the great losses to the property of the state and the people. The research object is the sinking bridge area in the city where waterlogging occurs frequently and is widely concerned. By checking the current drainage capacity of the urban sinking bridge area and diagnosing the causes of waterlogging in the sinking bridge area in the research process, the reconstruction scheme of drainage facilities in the sinking bridge area is analyzed, and the prevention suggestions and solutions targeted for the waterlogging problems in the sinking grade separations.
