Title:
RECESS STRUCTURE FOR REINFORCING CONNECTION BETWEEN RAILWAY SLEEPER AND TRACK BED, AND CONSTRUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/125503
Kind Code:
A1
Abstract:
Embodiments of the present invention disclose a recess structure for reinforcing a connection between a railway sleeper and a track bed, the recess structure being used in a ballastless track to reinforce the connection between a prefabricated sleeper unit and a subsequently-placed track bed. A reinforcement member is provided at one or more sidewalls in a transverse direction of the railway sleeper, that is, in a longitudinal direction of the track. The reinforcement member is a recess recessed inward from the sidewalls of the railway sleeper, such that during a pouring and placing process of the track bed, the recess and a certain height of the railway sleeper are buried in concrete of the track bed and integrated with the same by means of concrete pouring, the concrete directly filling the recess so as to reinforce the connection between the railway sleeper and the track bed.
