旧桥桥面应急排水与收集系统设计

某旧桥跨越饮用水源头,其排水系统缺失,桥面排水直排江体可能会对水体环境产生一定的影响。针对该情况,设计了一种旧桥桥面应急排水与收集系统。该系统通过设置纵向排水管、危化品识别传感器、控制开关、应急池,可实现对桥面初期雨水、桥面暴雨和桥面危化品泄漏等多种情况分流导排。同时设置溢流管、沉沙箱和橡胶伸缩软管等装置,提高了系统的使用功能和寿命。该系统设计新颖、实用,相关成果可为类似桥梁应急排水设计提供参考。

Design of Emergency Drainage and Collection System for Old Bridge Deck

An old bridge spans the source of drinking water. Its drainage system is missing. The bridge deck drainage directly into the river body may have a certain impact on the water environment. In view of this situation, an emergency drainage and collection system for old bridge deck is designed. The system can realize the diversions and drainages of the initial rainwater, deck rainstorm and deck dangerous chemical leakage by setting the longitudinal drainage pipe, dangerous chemical identification sensor, control switch and emergency pool. At the same time, the overflow pipe, grit chamber and rubber expansion hose are set to improve the service function and service life of the system. The design of the system is novel and practical. The relevant results can provide reference for the emergency drainage design of similar bridges.
