GROUND INJECTION METHOD AND GROUND INJECTION MATERIAL
To provide an environmentally friendly ground injection method and ground injection material by converting the conventional qualitative techniques into quantitative techniques in order to further develop the conventional invention and reduce the environmental load of the ground injection.SOLUTION: The present invention relates to a ground injection material that is made of non-alkali silica grout with a silica concentration of 1 to 40 w/vol% and a pH of 1 to 10, and is injected into the ground to form a ground improvement area. The ground injection material contains water-soluble reaction products such that the concentration of the water-soluble reaction products derived from the ground injection material does not affect the environment within the ground improvement area, and consists of a silica concentration that meets the injection purpose for the ground conditions and a formulation that is compatible with the applied construction method.SELECTED DRAWING: None
【課題】従来の発明をさらに発展せしめ、注入地盤の環境負荷を低減するために、従来の定性的な技術を定量的技術として、環境保全型の地盤注入工法および地盤注入材を提供する。【解決手段】シリカ濃度が１～４０ｗ／ｖｏｌ％、ｐＨが１～１０である非アルカリシリカグラウトからなり、地盤に注入して地盤改良領域を形成する地盤注入材である。地盤注入材は、地盤注入材由来の水溶性反応生成物の濃度が、地盤改良領域内で環境に影響を及ぼさない程度の水溶性反応生成物を含み、かつ、地盤状況に対して注入目的を満たすシリカ濃度と適用する施工法に適合した配合処方からなる。【選択図】なし
