EXPANSION-BLADE EXCAVATOR AND CAISSON SKELETON INSTALLATION METHOD
To provide an expansion-blade excavator and a caisson skeleton installation method, which can effectively excavate hard subsoil with a single type of excavator enabling effective installation of caissons.SOLUTION: An expansion-blade excavator 100 in this invention comprises a base machine 10 and an expansion-blade excavator body 30 suspended from the base machine 10 with a kelly-bar 20 to excavate subsoil G in the vertical direction along the inner wall surface 205 of a cylindrical caisson skeleton 200 and to excavate the subsoil G in an oblique direction along the tapered surface 220 of a cutting edge 210 of the caisson skeleton 200, and further comprises: a number of shaft-shaped expansion-blade cutters 60 arranged in parallel; rotary driving means 50 which rotates the multiple expansion-blade cutters 60 around each respective rotation axis; two swing driving means 70 which swing the multiple expansion-blade cutters 60 in varying timing; and a slide mechanism 80 which sandwiches and holds the multiple expansion-blade cutters 60 to synchronizingly move the multiple expansion-blade cutters 60 forward and back in the vertical direction.SELECTED DRAWING: Figure 6B
【課題】一種の掘削機にて効率的に硬質地盤を掘削することができ、このことにより、効率的なケーソン躯体の沈設を可能とする、拡翼掘削機とケーソン躯体の沈設方法を提供する。【解決手段】ベースマシン１０と、ベースマシン１０からケリーバー２０により垂下されている拡翼掘削体３０とを有し、筒状のケーソン躯体２００の内壁面２０５に沿って地盤Ｇを鉛直方向に掘削し、かつ、ケーソン躯体２００の刃口２１０のテーパー面２２０に沿って地盤Ｇを斜め方向に掘削する拡翼掘削機１００であり、並設する複数の軸状の拡翼カッタ６０と、複数の拡翼カッタ６０をそれぞれの回転軸を中心に回転させる回転駆動手段５０と、複数の拡翼カッタ６０を異なるタイミングで回動させる二つの回動駆動手段７０と、複数の拡翼カッタ６０を挟んで各拡翼カッタ６０を同期して鉛直方向に進退させるスライド機構８０と、を有する。【選択図】図６Ｂ
