高速铁路板式无砟轨道CA砂浆灌注施工技术

CA mortar grouting construction technology for slab ballastless track of high-speed railway

以哈齐客运专线HQTJ-3标段为项目背景,围绕板式无砟轨道CA砂浆灌注技术展开探讨,涉及搅拌、灌注两个方面,其中重点针对灌注步骤进行分析,包括施工流程、灌注施工、质控要点、砂浆养生及废弃物处理等。

Taking HQTJ-3 section of Line Haqi as the project background,this paper discusses CA mortar grouting technology for slab ballastless track,involving two aspects of mixing and pouring,in which the grouting steps are analyzed,including construction process,grouting construction,quality control points,mortar curing and waste treatment,etc.
