CRTSⅢ型板式无砟轨道是我国自主研发并具有完全自主知识产权的无砟轨道结构形式。论述自密实混凝土充填层施工工艺流程,从灌注漏斗、轨道板扣压装置和模板装置方面开展灌注工装研究;从轨道板腔湿润工艺、自密实混凝土灌注工艺改进和拆模与养护方面开展灌注工艺研究。通过自密实混凝土工艺性试验和施工改进与完善,确定关键工艺参数。通过揭板检验表明,自密实混凝土充填层施工质量稳定,施工技术满足工程要求。
CRTS Ⅲ type slab ballastless track is our own research and development and has completely independent intellectual property rights of ballastless track structure. Discusses the construction process of self-compacting concrete filling layer, carries out perfusion research on perfusion hopper, track plate buckling device and template device; conducts perfusion process research on wetting process of track plate cavity, improvement of self-compacting concrete pouring process and demolding and curing . Through self-compacting concrete test and construction improvement and improvement, to determine the key process parameters. Through the unverified board inspection, it shows that the construction quality of the self-compacting concrete filling layer is stable and the construction technology meets the engineering requirements.
