无砟轨道CRTSΙ型轨道板生产预制采用工厂化施工,它以水泥混凝土标号高、控制精度高、施工技术新等特点被称为无砟轨道最具代表性的施工工艺。而在整个CRTSΙ型轨道板生产预制中,轨道板的蒸汽养生是其中最核心的技术之一。采用蒸汽养生主要是为了适应沪宁城际铁路建设工期紧的特点。21 300块板的生产任务必须在9个月的时间内预制完成,如果不采取蒸养,而是过多地增加厂房占地面积和轨道板模具数量,对项目施工成本是个极大的浪费,所以搞好CRTSΙ型轨道板蒸养技术,是轨道板生产预制成功的关键。
Ballastless track CRTSI track plate production prefabricated factory construction, which is high cement concrete label, high control precision, construction technology and other characteristics is called ballastless track the most representative construction process. In the prefabrication of the complete CRTS I track plate production, the steam conditioning of the track plate is one of the core technologies. Steam is mainly used to adapt to the Shanghai-Nanjing intercity railway construction tight schedule. 21 300 plate production tasks must be prefabricated in 9 months time to complete, if not take steam curing, but too much to increase the plant floor area and the number of track plate mold, the project construction cost is a tremendous waste, Therefore, to improve CRTSI-type track plate steam curing technology is the key to successful prefabrication of track plate production.
