无砟轨道板采用CRTSⅡ型板,是我国高速铁路施工创新的先进技术成果。其中的水泥乳化沥青砂浆灌注是该项技术的关键。为彻底解决这一技术难题,在现场做了大量的灌浆和揭板试验,摸索总结出了一整套施工技术,保证了灌浆质量,加快了施工进度,降低了作业劳动强度,为CRTSⅡ型板式无砟轨道铺板灌浆施工的快速展开提供了施工参数和经验。
The ballastless track plate adopts CRTS Ⅱ type plate, which is an advanced technological achievement of high-speed railway construction in our country. The cement emulsified asphalt mortar infusion is the key to this technology. In order to completely solve this technical problem, a large number of grouting and unloading test were done in the field, and a series of construction techniques were explored to ensure the grouting quality, speed up the construction progress and reduce the labor intensity of work.快 Rapid deployment of track decking grouting provides construction parameters and experience.
