BAG BODY FOR FORMING FILLING LAYER
PROBLEM TO BE SOLVED: To enable work, in which a filling layer is provided in a clearance part formed between an outer peripheral surface of a protruding portion of roadbed concrete and an inner peripheral surface of a recess of a slab plate, to be performed with proper workability in construction of a slab type track.SOLUTION: An X-shaped core body 48 and a horizontal core body 49 are provided on an outer peripheral surface part 42F of a bag body 42 of a sealed structure using a nonwoven fabric sewn to constitute a sealed chamber 41 assuming almost the same shape as a space shape of a clearance part 15 and having a filler filling port 45 communicating with the sealed chamber 41.SELECTED DRAWING: Figure 2
【課題】 スラブ式軌道の施工において、路盤コンクリートの突起部の外周面とスラブ板の凹部の内周面との間にできる間隙部にてん充層を設ける作業を作業性よく行えるようにすること。【解決手段】 間隙部１５の空間形状と略同形状の密閉室４１を構成するように縫製され、密閉室４１に連通するてん充材充填口４５を有する不織布による密閉構造の袋本体４２の、外周面部４２Ｆに、Ｘ状芯体４８および水平芯体４９が設けられている。【選択図】図２
