跨河大桥桥面径流收集和事故应急系统设计

Design of Deck Runoff Collection and Accident Emergency System for River-crossing Bridge

以广州市南沙区上横沥大桥为背景,探讨了跨越敏感水域的桥梁路面径流收集及事故应急系统的设计,该设施在平时承担雨水径流简单处理的功能,在桥上有危险品泄露时,能够收集泄露的危险品及其冲洗水,希望能为类似桥梁排水设计提供参考。

Taking Shanghengli Bridge in Nansha District of Guangzhou as the background, this paper discusses the design of deck runoff collection and accident emergency system for the bridge crossing the sensitive waters. This system bears the function of simple treatment of rainwater runoff at ordinary time and can collect the leaked dangerous goods and flushing water when the dangerous goods are leaked on bridge, which can be referred for the drainage design of the similar bridges.
