PILE STRUCTURE, CONSTRUCTION METHOD OF PILE STRUCTURE, AND EXCAVATION AND AGITATION DEVICE
To provide a pile structure which has a simple configuration, can reduce the amount of cement milk to be used, has excellent adhesion property to the ground, and can sufficiently act against pressure in a horizontal direction.SOLUTION: A pile structure 1 comprises: a steel pipe pile 2 as a foundation pile buried in the ground; and a columnar improvement body 3 formed around the steel pipe pile 2 and formed of sediment solidified by cement. The columnar improvement body 3 is formed from the ground surface to a depth L2 shorter than a length L1 of the steel pipe pile 2. A tip blade 2A is attached to a lower part of a steel pipe of the steel pipe pile 2. A diameter D of the columnar improvement body 3 is larger than a diameter d2 of the tip blade 2A.SELECTED DRAWING: Figure 1
【課題】構成が簡単で、セメントミルクの使用量を少なくでき、地盤との密着が良くなり、水平方向の圧力に対して十分に対抗することができる杭構造を提供する。【解決手段】地中に埋設された基礎杭としての鋼管杭２と、鋼管杭２の周囲に形成された、土砂をセメントで固めた柱状改良体３とを備える杭構造１であって、柱状改良体３は、地表から鋼管杭２の長さＬ１より短い深さＬ２まで形成されている。鋼管杭２は鋼管の下部に先端翼２Ａが取付けられており、柱状改良体３の直径Ｄは、先端翼２Ａの直径ｄ２より大きい。【選択図】図１
