Repair structure of slab type trajectory and repair method of slab type trajectory

摘要

PROBLEM TO BE SOLVED: To provide a repair structure of a slab-type track having no necessity for using a release sheet, removing a frame mold, hardening a repair filler by pouring it into a bag body, pouring the repair filler once again, and capable of efficiently performing repair work, and a repair method of the slab-type track.SOLUTION: In a repair structure of a slab-type track in which a filler layer is arranged while being sandwiched between at least a concrete roadbed and a track slab, and a track rail is arranged on the track slab, the repair structure of the slab-type track comprises an embedded frame mold at least at a part of an external peripheral edge of the filler layer, and a repair filler is enclosed in at least either of the inside of the embedded frame mold and the inside of a region at the inside rather than the embedded frame mold.SELECTED DRAWING: Figure 7
