Summary:PROBLEM TO BE SOLVED: To provide a water stop method by freezing, which allows materials to be easily collected and carried around, put in by passing through a middle and small-diameter pipe and stop water by freezing in a short time even in a blocked area where water flows.SOLUTION: In a water stop method by freezing, a water permeable and expansible bag body containing powder of polymer water absorbing material is put in a target place in a blocked area where water flows through a middle and small-diameter pipe, which makes the polymer water absorbing material into filling components containing absorbed water. A wall is formed by accumulating these filling components, and subsequently the wall is frozen to form a water stop wall.SELECTED DRAWING: None 【課題】材料の回収ならびに持ち運びが容易で、中小口径の管を通して投入可能であり、水の流れがある閉塞された領域でも短時間で凍結止水することができる凍結止水方法を提供する。【解決手段】高分子吸水材の粉末を内蔵させた透水性かつ伸縮性袋体を、中小口径の管を通して、水の流れがある閉塞された領域内の目的場所に投入し、前記高分子吸水材が吸水した水分を含む充填部材となし、それらを積み重ねて壁を形成させた後。該壁を凍結させて止水壁を形成させることを特徴とする凍結止水方法である。【選択図】なし
