摘要： PROBLEM TO BE SOLVED: To provide a foundation structure capable of sufficiently ensuring bearing capacity to reduce cost and enlarging an applicable extent regardless of hardness of the ground and a construction method of the foundation structure.
SOLUTION: The ground near the front end of a pile is loosened after it has been confirmed that the front end of the pile of a steel pipe pile 2 is arrived to a bearing layer, and after then, load of an upper structure 4 is added to make the settlement of the steel pipe pile 2 by a loosening part to display bearing capacity RP1 of the front end of the pile and, at the same time, ground reaction force also acts to the bottom of a pressure resisting slab 3 making the settlement accompanied with the steel pipe pile 2 to obtain bearing capacity RS. Accordingly, bearing capacity of the front end of the pile is sufficiently ensured to enable bearing capacity (RP1+RP2+RS) of the whole foundation structure to rise, it can be also applied to a large scaled building 1 while contemplating the reduction of a cost without increasing a pile diameter or the number of piles. Further, the settlement of the steel pipe pile 2 is hard to occur after the display of the bearing capacity RP1, and differential settlement can be prevented even if a surface layer ground is weak.

摘要： PROBLEM TO BE SOLVED: To provide a foundation structure and a construction method of the foundation structure, capable of reducing the cost while securing a sufficient bearing capacity, and extending the application range regardless of the hardness of the ground.
SOLUTION: The ground in the vicinity of a pile tip of a steel pipe pile 2 is loosened after confirming that the pile tip reaches a support layer, and the load of an upper structure 4 is subsequently added thereto, whereby the steel pipe pile 2 is settled by the loosened portion to cause the pile tip to develop a bearing capacity RP1, and a bearing capacity SR is also obtained by action of ground reaction on the bottom surface of a pressure resisting slab 3 settling with the steel pipe pile 2. Accordingly, the bearing capacity of the pile tip can be sufficiently secured to enhance the overall bearing capacity (RP1+RP2+RS) of the foundation structure, and the foundation structure can be applied to a large-scaled building 1 while reducing the cost without increase of pile diameter or the number of piles. Further, since the settlement of the steel pipe pile 2 is hardly caused after the tip support force RP1 is exerted, uneven settlement can be prevented even if the surface layer ground is soft.

摘要翻译：要解决的问题：为了提供基础结构的基础结构和施工方法，能够在确保足够的承载能力的同时降低成本，并且延长施加范围，而不管地面的硬度如何。解决方案：确认桩顶到达支撑层后，钢管桩2的桩顶附近的地面松动，随后将上部结构体4的载荷加入其中，由此钢管桩2由松动部分沉降，使桩端产生承载力RP1，并且通过在与钢管桩2沉降的耐压板3的底面上的地面反作用来获得承载力SR 因此，可以充分确保桩头的承载力，以提高基础结构的总承载力（RP1 + RP2 + RS），并且可以将基础结构应用于大型建筑1，同时降低成本不增加桩直径或桩数。此外，由于在施加末端支撑力RP1之后难以引起钢管桩2的沉降，因此即使表层地面柔软，也可以防止不均匀的沉降。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a rotational intrusion steel pipe pile capable of heightening front end bearing force while suppressing labor, time and cost required for construction.
SOLUTION: The substrate on the upper side of the inclined plate 4 is constrained with the outer circumferential plate 5 by providing the whole ring-like outer circumferential plate 5 along the outer circumferential edge of an inclined plate 4 of a blade section 3 and, at the same time, it can be hard to have an influence of the slack of the upper substrate, and since the fall of bearing force with the slack of the substrate is relaxed, the front end bearing force can be heightened. Accordingly, since sufficient front end bearing force can be obtained without carrying out consolidation of foundation caused by discharge of cement-milk etc., labor, time and cost required for the construction of a pile can be reduced and, at the same time, an influence on ground water environment by cement etc. can be eliminated.

摘要翻译：要解决的问题：提供一种能够提高前端承受力的旋转侵入钢管桩，同时抑制施工所需的劳动力，时间和成本。解决方案：通过沿叶片部分3的倾斜板4的外圆周边缘设置整个环形外周板5，倾斜板4的上侧的基板被外周板5约束并且同时可能难以影响上基板的松弛，并且由于随着基板的松弛的承载力的下降而松弛，因此可以提高前端承载力。因此，由于能够在不进行由水泥浆等排出而引起的基础的固结的情况下获得足够的前端承受力，所以可以减少桩的施工所需的劳动力，时间和成本，同时，可以消除水泥等对地下水环境的影响。版权所有（C）2007，JPO＆INPIT
