FOUNDATION IMPROVEMENT UNIT AND FOUNDATION IMPROVING MACHINE
PROBLEM TO BE SOLVED: To enable a long pile to be installed.SOLUTION: A foundation improvement unit 3 comprises: a tubular rod 13 which has a boring tool 14 on its lower part that bores a hole to be injected with a foundation improving material and is vertically disposed as a channel for the foundation improving material; a leader 9 which is erected at rear side of the rod 13; an attached leader 10 which is lighter in weight per unit length compared to the leader 9 and erected on an upper end of the leader 9 so as to be stretchable above the leader 9; a rail 11a which is disposed across the leader 9 and the attached leader 10; a swivel joint 16 which is fitted to an upper end of the rod 13 so that the swivel joint can relatively rotate and move up and down along the rail 11a, and is connected with a hose for feeding the foundation improving material; a rod chuck 12 which is fitted so as to move up and down along the rail 11a, and holds or releases the rod 13 and rotates the held rod 13; and a lifting mechanism 17 which moves up and down the rod chuck 12.SELECTED DRAWING: Figure 1
【課題】長い杭を打つことを可能にする。【解決手段】地盤改良ユニット３は、地盤改良材を注入する穴を掘削する掘削具１４が下部に取り付けられ、地盤改良材の流路として鉛直に配置される管状のロッド１３と、ロッド１３よりも後方に立設されるリーダ９と、リーダ９と比較して単位長さ当たりの重さが軽く、リーダ９よりも上方で伸縮可能となるようにリーダ９の上端に立設される付属リーダ１０と、リーダ９から付属リーダ１０にわたって設けられるレール１１ａと、ロッド１３の上端に相対回転可能に取り付けられると共にレール１１ａに沿って昇降可能に設けられ、地盤改良材を供給するホースが接続されるスイベルジョイント１６と、レール１１ａに沿って昇降可能に設けられ、ロッド１３を保持又は解除すると共に保持したロッド１３を回転させるロッドチャック１２と、ロッドチャック１２を昇降させる昇降機構１７とを備える。【選択図】図１
