Excavator

Abstract

Abstract PURPOSE:To permit the placement of a continuous pillar-row sheating wall by allowing the turning of a side rod to any position at a center rod as a supporting point. CONSTITUTION:The upper ends of two center rods 4 whose axial centers are matched on a straight line are rotatably supported on a slider 3 provided to a leader mast 1, side rods 5 movable to a given position at the rods 4 as supporting points are provided on both sides of the rods 4, stirring augers 12 and 13 are provided to the lower ends of the rods 4 and 5, and the gears 16 of the rods 4 driven by a driver 15 are engaged with the gears 8 of the rods 5 through an intermediate gear 17. The rods 5 are stopped at a given angle to straight line leading to the axial centers of the rods 4, excavation is made, and then the rods 4 and 5 are drawn out, whereupon a pillar-row soil cement pile A of a semicircular form is formed. In the same way, a cement pile A' is placed to form a continuous pillar-row sheating wall B of a round form.
