城市中小桥梁防排水精细化设计

Research on fine design of urban small and medium-sized bridge anti-drainage

桥梁防排水系统为附属结构,设计深度往往不够,桥面铺装、人行道分隔带、锥坡等经常出现因水破坏的问题且得不到有效解决。分析桥梁因防排水系统引起的病害原因,提出防排水的细节设计是桥梁防排水能否有效运行的关键,并针对桥面排水设施、人行道分隔带及锥坡提出改进措施和精细化的设计方案,对同类工程有一定的指导作用。

Bridge anti-drainage system is an auxiliary structure,the design depth is often insufficient,bridge deck pavement,sidewalk divider,cone slope and other problems often appear due to water damage and can not be effectively solved.This paper analyzes the causes of bridge diseases caused by the anti-drainage system,and points out that the detailed design of anti-drainage is the key to the effective operation of bridge anti-drainage,and puts forward improvement measures and fine design schemes for bridge floor drainage facilities,sidewalk dividers and conical slopes,which have certain guiding role for similar projects.
