The invention relates to the field of track board production, and discloses a manufacturing process suitable for an alpine region high-speed railway large-gauge track board. The process includes the steps of neatly placing and fixing track board dies, making longitudinal reinforcing steel bars and transverse reinforcing steel bars penetrate through reinforcing steel bar fixing holes, making the longitudinal reinforcing steel bars and the transverse reinforcing steel bars connected with longitudinal connecting pull rods and transverse connecting pull rods through nuts respectively, starting longitudinal push oil cylinders and transverse push oil cylinders, tensioning the longitudinal reinforcing steel bars and the transverse reinforcing steel bars through a longitudinal tensioning platform and a transverse tensioning platform respectively, controlling the tensioning amounts of the longitudinal tensioning platform and the transverse tensioning platform through a numerical control platform, and pouring concrete in an area between the trail board dies to form the track board. The strength of the track board is improved, the adaptability of the produced track board is high, labor intensity is lowered, and work efficiency is improved.
Description
technical field [0001] The invention relates to the field of track slab production, in particular to a manufacturing process suitable for large-gauge track slabs of high-speed railways in alpine regions. Background technique [0002] High-speed railways have the characteristics of high speed, high traffic density, high requirements for passenger comfort, and maintenance and repair work can only be carried out within a limited time after nighttime shutdown. The track system directly bears the train load, which is related to traffic safety. Therefore, high-speed railways The performance requirements of the track system are higher. Due to its high stability, high ride comfort and less maintenance, ballastless track has been widely used in high-speed railways around the world in recent years. Among them, slab ballastless track is a commonly used track type, and slab ballastless track The key technology of the track lies in the track plate and its manufacturing process. Slab ba...
