CASING PIPE AND CONSTRUCTION METHOD FOR CRUSHED STONE PILE
PROBLEM TO BE SOLVED: To provide a casing pipe that enables a crushed stone pile to be constructed by using a single spindle-type construction machine, and a construction method for the crushed stone pile.SOLUTION: A casing pipe includes: a casing 10; an outer blade 20 that is formed at the tip of the casing 10 and on an outer peripheral surface 111; and an inner blade 30 for compaction, which is formed at the tip of the casing 10 and on an inner peripheral surface 112. The outer blade 20 is inclined with respect to a surface orthogonal to an axial direction of the casing 10. The inner blade 30 is inclined in a direction opposite to a direction of the outer blade 20.SELECTED DRAWING: Figure 3
【課題】単軸式の施工機械を用いて砕石杭を施工できるケーシングパイプおよび砕石杭の施工方法を提供すること。【解決手段】ケーシングパイプは、ケーシング１０と、ケーシング１０の先端部であって外周面１１１に形成された外羽根２０と、ケーシング１０の先端部であって内周面１１２に形成された締固め用の内羽根３０とを備える。外羽根２０は、ケーシング１０の軸方向に直交する面に対して傾斜する。内羽根３０は、外羽根２０とは逆向きに傾斜する。【選択図】図３
