摘要
传统的公路桥梁排水设计,未考虑地域性差异,仅简单地遵循规范要求,其存在外挂式排水管老化脱落、环境协调性差、缺乏针对性等一系列问题。依托工程实际,提出一种新的公路桥梁绿色防排水体系,其排水体系由桥面U型截面明式纵向排水沟、墙式护栏底部暗埋管式纵向排水管、埋入式桥墩竖向排水管、地面排水系统构成,并以夹流通道桥为例分析计算了其排水能力。结果表明,该方案不仅能确保桥面雨水污水及时排出,也能提高桥梁整体景观效果,改善与周围环境的协调性。
The traditional highway and bridge drainage design does not take into account regional differences,but simply follow the requirements of the code,which has a series of problems,such as aging and falling off of external drainage pipes,poor environmental coordination,lack of pertinence and so on.Based on the engineering practice,this paper puts forward a new green waterproof and drainage system for highway and bridge.the drainage system is composed of U-shaped longitudinal drainage ditch of bridge deck,hidden longitudinal drainage pipe at the bottom of wall guardrail,vertical drainage pipe of embedded pier and ground drainage system.Taking the clamped circulation road bridge as an example,its drainage capacity is analyzed and calculated.The results show that the scheme can not only ensure the timely discharge of Rain Water sewage from the bridge deck,but also improve the overall landscape effect of the bridge,improve its coordination with the surrounding environment.
