GROUND IMPROVEMENT PILE, CONSTRUCTION METHOD OF GROUND IMPROVEMENT BODY AND PROTRUSION OF GROUND IMPROVEMENT PILE
To provide a ground improvement pile, a construction method of a ground improvement body and a protrusion of the ground improvement pile in which a core material is sunk with almost no gap between an improved body formed by injecting a solidifying material into the ground and the horizontal strength of the core material is prevented from lowering with a simple configuration.SOLUTION: A ground improvement pile comprises a cylindrical core material to be sunk in an improved body formed by injecting a solidifying material into the ground, and a protrusion 12 attached to an outer periphery of the core material and protruding in the radial direction of the core material. The protrusion 12 includes a skeleton 16 that partitions a communication path 14 in the protrusion 12. The communication path 14 communicates on both sides of the protrusion 12 in the axial direction of the core material. The skeleton 16 has an outer wall portion 18 extending in the axial direction and the circumferential direction of the core material and partitioning the outside of the communication path 14 in the radial direction of the core material.SELECTED DRAWING: Figure 6
【課題】地盤に固化材を注入して形成された改良体との間に略隙間無く芯材が沈設され、簡単な構成にて芯材の水平耐力の低下が防止された地盤改良用杭、地盤改良体の施工方法及び地盤改良用杭の突起を提供する。【解決手段】地盤改良用杭は、地盤に固化材を注入して形成される改良体に沈設される筒状の芯材と、芯材の外周に取り付けられ、芯材の径方向に突出する突起12と、を備え、突起12は、突起12内に連通路14を区画する骨格16を含み、連通路14は、芯材の軸線方向にて突起12の両側を連通し、骨格16は、芯材の軸線方向及び周方向に延在して芯材の径方向にて連通路14の外側を区画する外壁部18を有する。【選択図】図6
