CRTSⅢ型板式无砟轨道自密实混凝土填充层施工技术

Construction Technology of Self-compacting Concrete Filling Layer for CRTS Ⅲ Type Slab Ballastless Track

为解决高速铁路CRTSⅢ型板式无砟轨道自密实混凝土填充层施工问题,提高施工质量,规范施工作业,以郑徐客专为依托,从工艺原理、工艺流程、操作方法及施工效果等方面进行论述,取得了较好的现场效果,供类似工程施工借鉴。

In order to solve the construction problems of the self-compacting concrete filling layer of CRTs Ⅲ slab ballastless track of high-speed railway, improve the construction quality and standardize the construction operation, this paper, based on the Zhengzhou Xuzhou passenger dedicated railway, discusses the process principle, process flow, operation method and construction effect, and good results are achieved on site, which can be used to provide reference for similar engineering construction.
