INTER-SEGMENT LIMITING STRUCTURE HAVING CLAWED ENDS FOR TRACK-BEARING BEAM IN SINGLE TRACK SECTION OF LOW-SET LINE OF MID-TO-LOW SPEED MAGNETIC LEVITATION TRANSPORTATION PROJECT

摘要

An inter-segment limiting structure having clawed ends for track-bearing beam in a single track section of a low-set line of a mid-to-low speed magnetic levitation transportation project, comprising a roadbed ballast below the track-bearing beam (9), a bedding layer under the track-bearing beams (8), two adjacent track-bearing beam segments, a vertical dislocation-prevention butt strap (1), transverse dislocation-prevention bosses (2), and track-bearing beam backfill ballast (5). The vertical dislocation-prevention butt strap (1) is fixedly provided on the roadbed ballast below the track-bearing beam (9) and has lower ends extending into the roadbed ballast below the track-bearing beam (9). The dislocation-prevention reinforced concrete butt strap is provided at the position between segments of the track-bearing beam, and the track-bearing beam is provided on the same reinforced concrete dislocation-prevention butt strap having certain rigidity, effectively avoiding the problem of track profile irregularity caused by uneven settlement of the foundation below the track-bearing beam.
