Title:
BALLASTLESS TRACK CONNECTION STRUCTURE OF HIGH-SPEED RAILWAY
Document Type and Number:
WIPO Patent Application WO/2022/017278
Kind Code:
A1
Abstract:
A ballastless track connection structure of a high-speed railway, comprising a main line ballastless track (10) and a ballasted track temporary line (20) located on one side of the main line ballastless track (10). The ballasted track temporary line (20) consists of a ballasted track bed (21) and a railroad tie (22). A transition section (L1) is provided between the main line ballastless track (10) and the ballasted track temporary line (20) to use as the temporary line transition connection foundation. A main body of the transition section (L1) is a reinforced concrete widened track bed (30) poured on the outer side of an existing ballastless track bed (12). A certain length in front of the transition section (L1) and the main line ballastless track (10) is a track surface elevation lifting section (L2). Assembling track bearing tables (40) are fixedly provided on top surfaces of the existing ballastless track bed (12) and the reinforced concrete widened track bed (30) in the track surface elevation lifting section (L2). By means of the assembling track bearing tables (40), a temporary line steel track (23) is locked, and the geometry of the track surface is arranged for completing the temporary line connection. The connection structure shortens the construction time of the connection foundation to the greatest extent, and lays a solid foundation for connection to the main line ballastless track (10) in one maintenance window period after the underlying foundation defects of stations are thoroughly treated.
