TELESCOPIC CONSTRUCTION LEADER
PROBLEM TO BE SOLVED: To provide a telescopic construction leader which is adjustable in height, and can adopt a variety of engagement guides for guiding a ground improvement device.SOLUTION: A telescopic construction leader 10 comprises: unit link member connecting bodies 1A, 1B which are formed by rotatably and sequentially connecting a plurality of pieces of unit link members 11a, 11b by using a connecting member; tip connecting parts 2 which connect tips of the unit link member connecting bodies to each other; rotating bodies 3a, 3b which reel or pay out the unit link member connecting bodies 1A, 1B; engagement guide parts 4a which are formed at the unit link connecting members 1A, 1B, or at the tip connecting parts 2, and guide a ground improvement device; and rotating body drive means which drives the rotating bodies. The unit link member connecting bodies 1A, 1B have connecting faces in which the connecting member are formed and non-connecting faces, and a columnar leader 7 is formed by the abutment of the non-connecting faces of the unit link connecting bodies 1A, 1B which are paid out of the rotating bodies 3a, 3b on each other.
【課題】高さ調整が自在で、地盤改良装置をガイドする種々の係合ガイド部を採り得る伸縮施工リーダーを提供する。【解決手段】単位リンク部材１１ａ、１１ｂの複数個を、連結部材を用いて回転可能に順次連結して形成された単位リンク部材連結体１Ａ、１Ｂと、該単位リンク部材連結体のそれぞれの先端を結合する先端結合部２と、該単位リンク部材連結体１Ａ、１Ｂをそれぞれ巻き取り又は送り出す回転体３ａ、３ｂと、該単位リンク部材連結体１Ａ、１Ｂ又は該先端結合部２に形成される地盤改良装置をガイドする係合ガイド部４ａと、該回転体を駆動する回転体駆動手段を備え、該単位リンク部材連結体１Ａ、１Ｂには該連結部材が形成されている連結面と非連結面を有し、回転体３ａ、３ｂから送り出された単位リンク部材連結体１Ａ、１Ｂのそれぞれの非連結面同士が互いに当接して柱状のリーダー７を形成する伸縮施工リーダー１０である。【選択図】図１
