PROBLEM TO BE SOLVED: To provide a joint unit for track construction and a construction method using the same, used in railway track construction in which a bag filled with a filler is embedded into a gap between track structures, the joint unit and the track construction method allowing smooth progress in filling work for the filler into the bag and the filler to be filled at a plurality of necessary locations in a short period of time.SOLUTION: A joint unit for track construction includes at least a roughly straight tubular joint body 20 having a plurality of circumferential projection parts formed at a prescribed interval on an outer surface at an edge part 20a, a fastener 30 on a bag body side for fastening an inlet 52 of a bag body 50 with the edge part 20a of the joint body part 20, and a fastener 40 on a feed pipe side for fastening a feed pipe 62 with the other edge part 20b of the joint body part 20 while having the other edge part 20b of the joint body part 20 inserted into the feed pipe 62. A circumferential flat part is formed between the circumferential projection parts formed on the outer surface at the end part 20a of the joint body part 20, the circumferential flat part having the fastener 30 on the bag body side disposed thereon.SELECTED DRAWING: Figure 1 |
