Zusammenfassung:To provide a filling implement for surely and efficiently filling spaces caused on the rear face of a waterproof sheet, and a filling method.SOLUTION: The present filling implement 1 is for filling spaces C with a filler F, caused between a coating object (primary coating concrete 24) and a waterproof sheet 21 spread over the coating object when constructing a concrete underground structure. The filling implement 1 has a waterproof sheet body 2 jointed to a take-up part 21a of the waterproof sheet and having a through-hole 2a, a rear face plate 3 provided to the coating object side of the waterproof sheet, with an injection pipe 6 penetrating through the through-hole erected, and a front face plate 4 provided on an opposite side of the covering object of the waterproof sheet body, and sandwiching the water proof sheet body by coupling the waterproof sheet body with the rear face plate.SELECTED DRAWING: Figure 1 【課題】防水シート背面に生じた空隙を確実かつ効率的に充填する充填用器具及び充填方法を提供する。【解決手段】本充填用器具1は、コンクリート地下構造物の施工の際に被覆対象(一次覆工コンクリート24)と該被覆対象に展張した防水シート21との間に生じる空隙Cを充填材Fで充填する。そして、本充填用器具1は、防水シートの切取り部21aに接合され、貫通孔2aを設けられた防水シート体2と、防水シート体の被覆対象側に設けられ、貫通孔を挿通する注入管6が立ち上げられた背面プレート3と、防水シート体の被覆対象と反対側に設けられ、防水シート体を背面プレートとの締結によって挟み込む前面プレート4と、を備える。【選択図】図1
