DUST PREVENTION PROCESSING METHOD
PROBLEM TO BE SOLVED: To provide a dust prevention processing method capable of simply reproducing a dust scattering prevention effect of soil, even when the effect disappears in a part of the soil on which the effect is exerted.SOLUTION: In a dust prevention processing method for soil, water is sprayed so that capillary suction time of the soil can be 60 seconds or less, after an aqueous solution containing inorganic salt with deliquescency and a critical humidity of 50% or less is sprayed on the surface of the soil.SELECTED DRAWING: None
【課題】粉塵飛散防止効果を付与した土壌の一部でその効果が消失しても、その効果を簡便に再生することができる粉塵防止処理方法を提供する。【解決手段】土壌表面に、潮解性を有し、臨界湿度が５０％以下の無機塩を含む水系溶液を散布した後、前記土壌の毛細管吸引時間が６０秒以下となるように水を散布する、土壌の粉塵防止処理方法である。【選択図】なし
