我国铁路客运专线技术全面进入无砟轨道时代。无砟轨道作为一种新型的轨道结构,已经成为未来我国轨道交通建设的发展方向。此文对此无砟轨道道床中的Ⅱ型板的制作工艺进行阐述,并对预制板场的布置和规模进行探讨,以期为轨道板预制场等大临工程费用的计算提供基础资料。
China’s railway passenger dedicated line technology into the era of ballastless track. As a new type of orbital structure, ballastless orbit has become the development direction of China’s rail transit construction in the future. In this paper, the production process of Type II slab in ballastless bed is elaborated, and the layout and scale of prefabricated slab yard are discussed in order to provide the basic data for the calculation of large slab construction cost such as track slab prefabricated yard.
