AI Technical Summary

Problems solved by technology

Since the connecting piece is rigid in the lateral direction, the lateral force received between the track plate and the mortar layer matrix will destroy the fixed connection between the track plate and the connecting piece, reducing the fixing effect of the connecting piece or even failing

Abstract

The invention discloses a ballastless track slab connecting piece and a ballastless track and belongs to the field of rail traffic. The connecting piece comprises a connecting head and a connecting rod, wherein the connecting head is inserted in a track slab, fixedly connected with the track slab and provided with a cavity, and the cavity communicates with the outside through a channel; and the connecting rod comprises a rotary head, the rotary head is embedded in the cavity of the connecting head and can freely rotate relative to the connecting head, and the connecting rod is inserted in a mortar layer and a base body and fixedly connected with the mortar layer and the base body.

Description

Technical field [0001] The invention relates to the field of railway construction. Background technique [0002] Ballastless track (nonballasted-track) refers to the track structure that uses concrete, asphalt mixture and other integral foundations to replace the loose gravel track bed. It is also called ballastless track and is the most advanced track technology in the world today. Compared with the ballasted track, the ballastless track avoids splashing ballast, has good smoothness, good stability, long service life, good durability, less maintenance work, and trains running at speeds of more than 350 kilometers per hour. [0003] Ballastless track is a steel rail fixed to the track plate through fasteners, etc. The structure of the ballastless track mainly includes CRTSⅠ double-block ballastless track, CRTSⅡ double-block ballastless track, CRTSⅠ slab ballastless track and CRTSⅡ. Type slab ballastless track, CRTSⅢ type slab ballastless track, in the turnout section, there are ma...
