BUNDLED INJECTION PIPES AND GROUND INJECTION METHOD
PROBLEM TO BE SOLVED: To provide bundled injection pipes and a ground injection method for injecting and interpenetrating injection material into respective stages in a porous wall while preventing the injection material discharged into a drilled hole from discharge ports of infusion capillaries from being mixed in the drilled hole or flowing out to the ground.SOLUTION: Plural injection pipes 4 each of which has a discharge port 4a at the lower end part thereof are bundled with each other so that the discharge ports 4a of the respective injection pipes 4 are positioned at different position in the axial direction of the tubes. The plural injection pipes 4 and 4 are bundled so that a space is formed for filling a drilled hole 2 with a seal grout 3 by means of plural permeable separators 5 between the injection pipes 4 and 4.SELECTED DRAWING: Figure 1
【課題】各注入細管の吐出口から削孔内に吐出した注入材が削孔内で混合したり地上に流出したりするのを防止して、孔壁内の各ステージに浸透注入させるようにした結束注入管および地盤注入工法を提供する。【解決手段】下端部に吐出口4aを有する複数の注入管４を各注入管４の吐出口4aが管軸方向の異なる位置にくるように互いに添い合わせる。添い合わせた複数の注入管4,4を複数の透過性セパレーター５によって各注入管４と注入管４との間に削孔２内に充填されたシールグラウト３が充填可能な隙間を有するように形成する。【選択図】図１
