摘要

高速铁路路基电缆槽采用的钢筋混凝土在工厂预制,待路基基床表层施工完毕后,采用切割的方法把路肩位置填筑好的路基表层填筑体去除,然后再在切割面上施工电缆槽和路基护肩。路基表层填筑材料为级配碎石,由于其强度较大,造成切割困难、效率低、影响环境等问题。针对这些问题,本文通过研究,提出了高速铁路路基电缆槽及护肩结构新的施工方法,解决了传统施工存在的技术问题,对工程实践具有重要的借鉴意义。
        The reinforced concrete for cable groove of high-speed railway subgrade is prefabricated in the factory. After completion of the surface layer construction of the subgrade,the filling body of the surface layer of the subgrade at the filling position of the shoulder is removed by cutting method,and then the cable groove and the shoulder of the subgrade are constructed on the cutting surface. Because the surface filling material for subgrade is graded crushed stone with high strength,the cutting construction is difficult and the efficiency is low,and it has a large impact on environment. In view of these problems,through the analysis of innovative methods,this paper puts forward new construction methodssubgrade cable groove and shoulder protection structure—for high-speed railway. It solves the technical problems due to traditional construction,and has important reference significance for engineering practice.
