既有铁路站场改造施工技术

Construction Technology of Existing Railway Station Reconstruction

既有铁路站场改扩建工程施工中,涉及路基、桥涵、轨道及四电等多个专业,施工难度大,技术含量高,安全风险极大。从现场技术调查、提报轨料计划、新旧标高衔接、新旧平面衔接、车站咽喉区拉坡、封锁施工轨道质量控制、安全措施等7个方面进行了详细叙述,总结了既有铁路站场改造施工关键技术。

In the construction of the existing railway station expansion project,there are many specialties,such as roadbed,bridge and culvert,track and four electric power,so it is difficult to construct,and has high technical content and high security risk. Described in detail from the on-site technical investigation,report material plan,new old plane elevation of cohesion,cohesion,slope,pull the throat area of station track blocking the construction quality control and safety measures in 7 aspects,summarizes the existing railway station reconstruction key construction technology.
