GROUT FILLING METHOD AND GROUT FILLING STRUCTURE
To reduce work on the top of a slab while properly grouting.SOLUTION: There is provided a grout filling method for filling the interior of a sheath pipe 100 embedded in a floor slab 2 and containing PC steel 5 inside with grout G, in which: grout G is injected into the interior of sheath pipe 100 from the bottom surface 4 of the floor slab 2 via injection pipe 111 communicated to the top end 113 of the interior 112 of sheath pipe 110 with injection pipe, in an injection process; and exhaust is exhausted from the interior of the sheath pipe 100 via an exhaust pipe 121 communicated from the upper end 123 of the interior 122 of the sheath pipe 120 with the exhaust pipe to the bottom surface 4 of the floor slab 2, in an exhaust process. Since grout G is injected and exhausted from the bottom surface 4, work on the top surface 3 of the floor slab 2 can be reduced. Because grout G is injected from the upper end 113 and exhausted from the upper end 123, remaining air inside the sheath tube 100, which is an obstacle to reinjection of grout G, can be reduced. Thus, work on the top surface 3 of the floor slab 2 can be reduced while properly filling the grout G.SELECTED DRAWING: Figure 1
【課題】適切にグラウトを充填しつつ床版の上面での作業を低減する。【解決手段】床版2に埋設されて内部にPC鋼材5を収容したシース管100の内部にグラウトGを充填するグラウト充填方法で、注入工程では、床版2の下面4から注入管付シース管110の内部112の上端部113に連通した注入管111を介してシース管100の内部にグラウトGを注入し、排気工程では、排気管付シース管120の内部122の上端部123から床版2の下面4に連通した排気管121を介してシース管100の内部から排気する。下面4からグラウトGを注入及び排気するため、床版2の上面3での作業を低減できる。上端部113からグラウトGを注入し、上端部123から排気するため、シース管100の内部にグラウトGの再注入の障害となる空気が残留することを低減できる。適切にグラウトGを充填しつつ床版2の上面3での作業を低減できる。【選択図】図1
