INTER-SEGMENT LIMITING STRUCTURE FOR TRACK-BEARING BEAMS ON DOUBLE-TRACK SECTION OF LOW-SET MID-TO-LOW SPEED MAGNETIC LEVITATION TRANSPORTATION PROJECT LINE

摘要

An inter-segment limiting structure for track-bearing beams on a double-track section of a low-set mid-to-low speed magnetic levitation transportation project line, as well as a clawed-end inter-segment limiting structure for track-bearing beams, comprises two single-track structures, wherein, each single-track structure comprises roadbed ballast (9a, 9b) below the rail-bearing beams, bedding layers (8a, 8b) under the rail-bearing beams, two adjacent track -bearing beams, vertical dislocation-prevention butt straps (1a, 1b), transverse dislocation-prevention bosses (2a, 2b) and track-bearing beam backfill ballast (5a, 5b). The vertical dislocation-prevention butt straps (1a, 1b) are fixedly arranged on the roadbed ballast (9a, 9b) below the track-bearing beams and the lower ends thereof extend into the roadbed ballast (9a, 9b) below the track-bearing beams. The dislocation-prevention reinforced concrete butt straps are arranged between the segment positions of the track-bearing beams, and the track-bearing beams are arranged on the same reinforced concrete dislocation-prevention butt straps with certain rigidity, thereby effectively avoiding the problem of track profile irregularity caused by uneven settlement of the foundation below the track-bearing beams.
