上跨铁路桥梁边梁+防撞墙一体化制架工法探讨

Discussion on the Integrated Framing Method of Upper Span Railway Bridge with Side Beam and Anti-collision Wall

本文通过对阜阳润河路上跨京九铁路立交工程一孔跨度35m的市政桥梁预制箱梁边梁+防撞墙一体化制架工法进行探讨,分析了预制箱梁边梁+防撞墙一体化制架工法中存在的梁体偏心、龙门吊和架桥机吊梁、梁体运输、梁体架设等存在的问题,并且通过分析,制订了解决问题的措施,通过实例,验证了该措施的有效性。为实施上跨铁路桥梁边梁+防撞墙一体化制架工法的制订提供了宝贵的经验。

This article discusses the integrated construction method of prefabricated box girder side beam and anti-collision wall of a municipal bridge with a span of 35 m across the Beijing-Kowloon Railway Interchange on Fuyang Runhe Road:and analyzes the prefabricated box girder side beam and anti-collision wall There are problems in the integrated construction method of beam body eccentricity,gantry crane and bridge girder crane,beam body transportation,beam body erection,etc.〉and through analysis,measures to solve the problems are formulated,and the measures are verified through examples Effectiveness.It provides valuable experience for the implementation of the integrated construction method of the side beam and anti-collision wall of the upper-span railway bridge.
