INJECTION DEVICE FOR HIGH PRESSURE INJECTION AGITATION METHOD
PROBLEM TO BE SOLVED: To miniaturize an injection device for high pressure injection agitation method, and furthermore reduce loss of energy of curing material liquid injected.SOLUTION: An injection device 10A is attached to the tip of an injection rod 20. The injection rod 20 and the injection device 10A are rotated around a rotary shaft in the construction. The injection device 10A has a columnar side face, and includes an injection material tank 11A in the inside thereof. The injection material tank 11A is spherical, and the center is present on the rotary shaft. An inner opening 16A of the injection material tank 11A is a plane containing the center of the spherical injection material tank 11A, and is positioned on the plane vertical to the rotary shaft. A curing material nozzle 15A is disposed radially from the opening 16A toward the side face of the injection device 10A. An opening 16B of the inside surface of the injection material tank 11A is at a point-symmetric position with the opening 16A with respect to the center of the injection material tank A on the plane. A curing material nozzle 15B is disposed radially from the opening 16B toward the side face of the injection device 10A.SELECTED DRAWING: Figure 1
【課題】高圧噴射攪拌工法用噴射装置を小型化し、噴射される硬化材液のエネルギー損失をより低減する。【解決手段】噴射装置１０Ａは注入ロッド２０の先端に装着される。施工時に、注入ロッド２０と噴射装置１０Ａは回転軸の周りを回転する。噴射装置１０Ａは、円柱状の側面を有し、内部に噴射材料槽１１Ａを備える。噴射材料槽１１Ａは、球形であり、その中心は回転軸上にある。噴射材料槽１１Ａの内面の開口１６Ａは、球形の噴射材料槽１１Ａの中心を含む平面であって回転軸と垂直な平面上に位置する。硬化材噴射孔１５Ａは、開口１６Ａから噴射装置１０Ａの側面に向けて半径方向に配設されている。噴射材料槽１１Ａの内面の開口１６Ｂは、その平面上で噴射材料槽Ａの中心に対して開口１６Ａと点対称の位置にある。硬化材噴射孔１５Ｂは、開口１６Ｂから噴射装置１０Ａの側面に向けて半径方向に配設されている。【選択図】図１
