Key innovative technology of CRTS III type pre-tensioning ballastless track slab by unit serial method

High-speed railway ballastless track two-way pre-tensioning prestressed track slab by unit serial method is a new type of track slab prestressed system developed in China. In Shandong Linqu, the first time in the world it achieves mass production of two-way pre-tensioning prestressed track slab Through research on system innovations of the partial prestressed "composite anchoring" technology and "unit serial method" manufacturing technique, this technical system has formed a two-way pre-tensioning prestressed track slab design and manufacturing technique, developed the track slab production equipment and formed a 24 h production process. This technology will be comprehensively promoted and applied in high-speed railway construction.
