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
