CHEMICAL INJECTION METHOD
PROBLEM TO BE SOLVED: To provide a chemical injection method for effectively conducting an improvement in a compaction strengthening area by an injection material and peripheral soil or soil by an injection chemical with a small quantity of chemical materials, by repeatedly injecting the injecting chemical material at a preset time interval by a small quantity and making them remain around the discharge portion of an injection pipe in an inside lower part of the ground.SOLUTION: When injecting a chemical material into the ground, a compaction density of an expected depth position is investigated, and the chemical material is supplied and injected at a preset time interval by a trace quantity into an injection pipe 10 inserted up to a predetermined depth based on the compaction density provided in this depth position, this operation is repeated by a predetermined number of times to make an injection chemical material remain dispersively in the ground around of an installation part of the injection pipe 10 and thus a compaction strengthening area Q of soil is formed, to strengthen the support ground of a building structure.SELECTED DRAWING: Figure 1
【課題】注入する薬液材を少量ずつ予め設定した時間間隔をおいて反復注入し、地盤の内下部で注入管の吐出周辺にとどめるようにすることで、注入材と周辺土壌とによる圧密強化領域或いは注入薬剤による土壌の改善を、少量の薬液材によって有効に処置する薬液注入工法を提供する。【解決手段】薬液材を地盤に注入するにあたり、予定する深さ位置の圧密度を調査し、この深さ位置で得た圧密度に基づいて、所定深度まで挿入した注入管１０に薬液材を微量ずつ予め設定した時間間隔で供給注入し、この操作を所定回数反復して前記注入管１０の設置周辺部の地中に注入薬液材を分散してとどまらせ土壌の圧密強化域Ｑを形成し、建造物の支持地盤を強化する。【選択図】図１
