市政桥梁雨水排水系统设计研究

Design and Study of Rainwater Drainage System of Municipal Bridge

市政桥梁排水系统设计需要结合桥梁结构形式进行,论文参考市政建筑屋面虹吸排水系统的工作原理,将其应用在市政桥梁工程中。通过设计试验得到市政桥梁系统虹吸式排水系统结构相关参数与排水能力数据,并且得到如下结论:(1)该排水系统具有较强的负压排水能力,满足日常的桥面雨水排水需要。(2)虹吸式排水模式可以应对更大的排水流量需求。(3)雨水篦子对于排水效果会产生影响,在设计与应用中需要加以重视和优化。

The design of municipal bridge drainage system needs to be carried out in combination with the form of bridge structure.This paper refers to the working principle of municipal building roof siphon drainage system,and applies it in municipal bridge engineering.Through design test,the structural parameters and drainage capacity data of siphon drainage system of municipal bridge system are obtained,and the following conclusions are obtained:(1)The drainage system has strong negative pressure drainage capacity to meet the daily rainwater drainage needs of the bridge deck.(2)The siphon drainage mode can cope with the greater drainage flow demand.(3)The rainwater grate will have an impact on the drainage effect,which needs to be emphasized and optimized in the design and application.
