To provide an underground structure, a method for constructing the underground structure, and a jig for constructing the underground structure, which can further improve pull-out resistance and sedimentation resistance.SOLUTION: An underground structure 10 includes a hollow cylindrical pile 11 and a reinforcing member 12 that is disposed inside the pile 11 and has an expansion mechanism that is expandable in a direction perpendicular to the direction in which the pile 11 extends. The pile 11 has a pair of protrusions 30 that are pushed outward toward the outside of the pile 11 from a base end 30a by the reinforcing member 12 in an expanded state. A tip 30b of the protrusion 30 is separated from the pile 11. The reinforcing member 12 is located above or below the base end 30a in the vertical direction.SELECTED DRAWING: Figure 4
【課題】耐引抜性及び耐沈降性をより向上できる地中構造体、地中構造体の施工方法、及び地中構造体の施工用治具を提供する。【解決手段】地中構造体１０は、中空筒状の杭１１と、杭１１の内側に配置され、杭１１の延在方向と直交する方向に拡張可能な拡張機構を有する補強部材１２とを備えている。杭１１は、拡張した状態の補強部材１２によって、基端部３０ａを起点にして杭１１の外側に向けて押し広げられた一対の突出部３０を有している。突出部３０の先端部３０ｂは、杭１１と切り離されている。補強部材１２は、基端部３０ａよりも鉛直方向上側又は下側に位置している。【選択図】図４
