摘要
先张法双向CRTSⅢ型预应力混凝土轨道板是具有我国自主知识产权的高速铁路无砟轨道结构。CRTSⅢ型轨道板预制的核心工艺是张拉技术,而张拉台座形式的不同决定了张拉工艺的不同,进而影响到生产车间的布局、工装设备的配置、建场工期的长短,从而影响生产功效和建场成本。根据哈牡客专轨道板场的建设实例,通过对轨道板预制台座的选型,从生产车间布置、工艺流程设计、设备投入等方面考虑,结合工期、生产效率、产品质量检验等因素,提出了影响CRTSⅢ型轨道板预制场规划与设计应着重考虑的条件。工程实践证明取得了良好的效果,对同类轨道板场的建设具有一定的参考价值。
Pretensioned two-way CRTS Ⅲ prestressed concrete track slab is a high-speed railway ballastless track structure with independent intellectual property rights in China. The core technology of CRTS Ⅲ track slab prefabrication is tensioning technology,and the different forms of tensioning pedestal determine the different tensioning technology,which further affects the layout of production workshop,the configuration of tooling equipment,the length of construction period,thus affecting the production efficiency and construction cost. According to the construction example of the track slab yard of HA Mu passenger dedicated line,through the selection of the track slab prefabrication pedestal,considering the layout of the production workshop,the design of the technological process and the input of the equipment,combined with the comprehensive consideration of the construction period,the production efficiency,the product quality inspection and other factors,this paper puts forward the conditions that should be emphatically considered in the planning and design of the track slab Prefabrication Yard of CRTS Ⅲ type. The engineering practice has proved that good results have been achieved,which has certain reference value and important reference significance for the construction of similar track slab field.
