WATER-REDUCING NATURAL GROUND IMPROVEMENT MATERIAL AND NATURAL GROUND STABILIZATION METHOD
PROBLEM TO BE SOLVED: To allow achieving reduction of cost for materials while securing cutoff water-reduction effects or natural ground improvement effects.SOLUTION: There is provided a water-reducing natural ground improvement material having cutoff water-reduction effects or natural ground improvement effects by filling the same in a rock mass or natural ground, consisting of an urethane-based cutoff material, having physical properties expanding even in contact with water, or in no contact with water, expansion ratio in the case in contact with water and expansion ratio in the case in no contact with water are preferably at least 3 times or more respectively, or the expansion ratio in the case in contact with water and the expansion ratio in the case in no contact with water are preferably almost same.SELECTED DRAWING: None
【課題】止水減水効果や地山改良効果を確保しつつ、材料にかかるコストの低減を図ることができる。【解決手段】岩盤又は地山に充填することで減水効果及び地山改良効果を有する減水地山改良材であって、ウレタン系止水材からなり、水と接触しても、水に対して非接触であっても発泡する物性であり、水に接触した場合の発泡倍率及び水に非接触の場合の発泡倍率は、それぞれ少なくとも３倍以上であることが好ましく、また水に接触した場合の発泡倍率及び水に非接触の場合で発泡倍率が略同一であることが好ましい減水地山改良材を提供する。【選択図】なし
