高边坡桩板墙与预应力锚索复合路基支挡结构施工

Construction of High Slope Pile Wall and Prestressed Anchor Cable Composite Subgrade Retaining Structure

预应力锚索桩板墙是一种复杂轻型支挡结构,应用其可有效解决铁路施工中高边坡路堤施工过程存在的问题。因此,该文研究铁路施工中高边坡桩板墙与预应力锚索复合路基支挡结构施工工艺。根据工程概况,从桩板施工、锚索施工以及挡土板施工三方面入手,介绍铁路高边坡挂线施工的具体流程、锚索施工工艺,提出质量控制方式,对施工过程中应注意和遇到的问题作出初步总结。

Prestressed anchor cable pile wall is a kind of complex lightweight retaining structure,which can effectively solve the problems existing in the construction process of high slope embankment in railway construction.Therefore,this paper studies the construction technology of high slope pile wall and prestressed anchor cable composite subgrade retaining structure in railway construction.According to the general situation of the project,starting from the three aspects of pile plate construction,anchor cable construction and retaining board construction,this paper introduces the specific process of railway high slope line hanging construction,introduces the anchor cable construction technology in detail,puts forward the quality control method,and makes a preliminary summary of the problems that should be paid attention to and encountered in the construction process.
