CRTSⅢ型轨道板是具有我国自主知识产权的高速铁路轨道。CRTSⅢ型轨道板主要有P5600、P4925、P4856三种板型。轨道板采用双向预应力混凝土结构,板面设置承轨台。轨道板在固定台座上采用反向模筑法生产,通过高精度、高刚度的定型钢模,保证轨道板制造精度和工效。CRTSⅢ型板实现了预制过程中承轨台空间几何位置的变化,曲线地段轨道板的制造通过调整承轨台,实现无砟轨道铺设后线路的高平顺性要求。通过对曲线模具制造和曲线模具的调整与检测确保曲线地段轨道板的制造精度进行了研究。
CRTS Ⅲ track plate is our own intellectual property rights of high-speed railway tracks. CRTS Ⅲ rail plate mainly P5600, P4925, P4856 three plate. Track plate using two-way prestressed concrete structure, set board bearing rail. Track plate on the fixed pedestal using reverse mold building production, through the high-precision, high-rigidity stereotypes die, rail plate manufacturing to ensure the accuracy and efficiency. The CRTS Ⅲ type plate realizes the change of the geometric position of the bearing rail table space during the prefabrication process. The manufacture of the curved track plate can realize the high ride comfort of the circuit after laying the ballastless track by adjusting the rail bearing platform. The manufacturing precision of curved track plate is studied by adjusting and testing the curve mold and curve mold.
