DEWATERING METHOD FOR CONCRETE AND DEWATERING APPARATUS FOR CONCRETE
PROBLEM TO BE SOLVED: To effectively drain excess water from concrete by enhancing drainage efficiency in a dewatering method for concrete.SOLUTION: There is provided a dewatering method for concrete, which comprises a step where a plurality of water passage holes 18 penetrating a frame main body 4 in thickness direction are formed on the frame main body 4, water permeable material 14 is arranged inside of the frame main body 4, and a water permeable sheet 10 is arranged inside of the water permeable material 14 to form a frame 2, a step of connecting a water absorbing part 20 to the water passage holes 18 from outside of the frame 2, a step of casting concrete C into the frame 2, and a step of absorbing water from the water passage holes 18 by applying negative pressure from the water absorbing part 20 to the frame 2.SELECTED DRAWING: Figure 1
【課題】コンクリートの脱水方法において、排水効率を高めてコンクリートから効果的に余剰水を排水する。【解決手段】型枠本体４に型枠本体４の厚み方向に貫通する通水孔１８を複数形成し、型枠本体４の内側に透水材１４を設けると共に、透水材１４の内側に透水シート１０を設けて型枠２を形成する工程と、型枠２の外側から通水孔１８に吸水部２０を接続する工程と、型枠２内にコンクリートＣを打設する工程と、吸水部２０から型枠２内に負圧をかけて通水孔１８から吸水を行う工程と、を備えていることを特徴とするコンクリートの脱水方法を提供する。【選択図】図１
