摘要
结合某下穿铁路的城市道路通道的引道段改造项目,分析旧下穿通道易发生渗漏水、不均匀变形等病害的原因,提出主体结构及防排水系统改造方案。通过保留原有挡墙结构,对车行道和防排水系统局部改造,降低工程投入,减少施工期环境影响,取得良好的社会效益和经济效益,可供类似工程借鉴。
Combined with the reconstruction project of the approach section of an urban road crossing the railway,the causes of problems such as water leakage and uneven deformation of the old underpass are analyzed,and the reconstruction scheme of the main structure and waterproof and drainage system is put forward.By reserving the original retaining wall structure and the partial reconstruction of carriageway and waterproof and drainage system,the project investment is reduced,the environmental impact during construction is also reduced,and good social and economic benefits are obtained,which can be used as reference for similar projects.
