FILLED LAYER FORMING BAG BODY, FILLED LAYER FORMING UNIT, AND FILLED LAYER FORMING METHOD
To provide a filled layer forming bag body, a filled layer forming unit, and a filled layer forming method using the filled layer forming bag body which makes it possible to improve workability at the time of forming a filled layer, and to form the filled layer with excellent durability.SOLUTION: A filled layer forming bag main body for use in a slab type track to form a filled layer in a gap between a recess in a semicircular shape in plan view formed at both ends in the rail installation direction of the track slab and a cylindrical or half-cylindrical projecting part projectingly formed on a concrete roadbed. It is provided with a bag main body formed to have substantially the same shape as the shape of a space forming the gap, and an extensible adjustment band arranged at both circumferential ends of the bag main body, and the total sum of the length in the circumferential direction of the inner peripheral surface of the bag main body and the length of the extendable adjustment band before extending is shorter than the circumferential length of the outer peripheral surface of the projecting part that contacts the bag main body and the extendable adjustment band.SELECTED DRAWING: Figure 2
【課題】てん充層を形成する際の作業性を向上させることを可能とし、かつ耐久性に優れたてん充層を形成できるてん充層形成用袋体、てん充層形成ユニット、および該てん充層形成用袋体を用いたてん充層形成工法を提供する。【解決手段】スラブ式軌道において、軌道スラブのレール敷設方向の両端部に形成された平面視略半円状の凹部とコンクリート路盤上に突出形成された円柱状または半割り円柱状の突起部との間の間隙部に、てん充層を形成するために用いられるてん充層形成用袋体であって、前記間隙部を形成する空間の形状と略同形状になるように形成される袋体本体と、前記袋体本体の周方向両端部に配置された伸張性調整帯とを備え、前記袋体本体の内周面の周方向の長さと、伸張前の前記伸張性調整帯との長さの総和は、前記袋体本体および前記伸張性調整帯と接触する前記突起部の外周面の周方向の長さよりも短い。【選択図】図２
