GROUND INJECTION MATERIAL, METHOD OF PRODUCING THE SAME, AND GROUND INJECTION METHOD
To provide: a ground injection material that causes no soil pollution even when silica ground containing silica material obtained by collecting silica in geothermal water, is used; a ground injection material that effectively utilizes the silica content in geothermal water by increasing the amount of the geothermal water-contained silica that can be used as the ground injection material; a method of producing the same; and a ground injection method using the same.SOLUTION: The ground injection material is composed of silica ground that contains, as active ingredients, silica material obtained by collecting silica in geothermal water, water glass, and an acidic reactant, in the ground injection material, the content of heavy metals contained in the silica material being equal to or less than a uniform drainage standard value or an environmental reference value.SELECTED DRAWING: None
【課題】地熱水中のシリカを収集したシリカ材を含むシリカグラウトを用いても、土壌汚染を生ずることがない地盤注入材、および、地熱水中に含まれるシリカ分の地盤注入材としての適合量を増やして地熱水中のシリカ分を有効に活用する地盤注入材、その製造方法、および、それを用いた地盤注入工法を提供する。【解決手段】地熱水中のシリカを収集したシリカ材と、水ガラスと、酸性反応剤とを有効成分として含むシリカグラウトからなる地盤注入材であって、シリカ材に含まれる重金属の含有量が、一律排水基準値または環境基準値以下である地盤注入材である。【選択図】なし
