PROBLEM TO BE SOLVED: To solve the problem that conventional auxiliary tools for assisting a prop used in the fields of agriculture, forestry, and gardening and the like have not had sufficient bearing power.SOLUTION: A socket pile 8 provided with a through hole 11 in the shaft center of the pile having lower end 10 in a conic or pyramid form is characterized by that the socket 8 is driven from the ground towards the underground, a prop 14 is penetrated through the through hole 11, further the prop 14 is driven into the underground, and thereby a supporting structure with the prop 14 is constructed to obtain a bearing power stronger than a conventional bearing power in which the bearing power of only the prop 14 is added to the bearing power of the socket pile 8.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】 農業、林業、造園等の分野で使用される支柱を補助する従来の補助具は、その支持力が十分ではなかった。【解決手段】 下端10を円錐又は角錐状とした杭の軸中心に貫通穴11を設けたソケット杭8であって、地面から地中に向けソケット杭8を打ち込み、貫通穴11に支柱14を貫通させ、さらに支柱14を地中に打ち込むことで支柱14による支持構造を構成することにより、ソケット杭8の支持力に支柱14単体の支持力を加えた従来よりも強力な支持力を得る。【選択図】 図3
