Embodiment Construction

[0042] Embodiments of the present invention will be described below with reference to the drawings.

[0043] The present invention and Figure 8-Figure 21 Compared with the traditional foundation formation method and the foundation body shown, it has basically the same structure, and the following emphatically describes the same structure as Figure 8-Figure 21 The difference between the traditional foundation formation method and the foundation body shown.

[0044] Such as figure 1 , 2 Shown, in the present invention, for the deep foundation body 2 of vertical building, toward the minimum principal strain direction ( figure 1 Arrow direction) radially set many rod-shaped reinforcements 3. Specifically, each reinforcing member 3 is arranged obliquely downward at an angle of θ=π / 4-φ / 2 (rad) with respect to the horizontal plane. Here, φ is the internal friction angle of the natural foundation 4 of the building foundation body 1, for example, when the natural foundation 4 ...

Abstract

A method of arranging reinforcements in forming a foundation of ground reinforcing type, by which great bearing forces can be provided to particularly a lifting load, and a foundation body. A multiplicity of rod-shaped reinforcements extending radially from a foundation body, which is built by digging through a natural ground, being arranged at predetermined intervals in an axial direction, and fixed in an interior of the surrounding natural ground, are arranged to align in a direction of minimum principal strain of the natural ground in the natural ground near the foundation body when a lifting force is applied to the foundation body.

Description

technical field [0001] The present invention relates to measures for strengthening the supporting force of foundations for construction and civil engineering. Background technique [0002] The supporting force of the foundation for construction and civil engineering is obtained by the reaction force of the surrounding foundation to the foundation when an external force is applied to the foundation. The applicant's Japanese Patent Publication No. 5-40085 has already proposed a method of forming a foundation and a foundation body for strengthening such a supporting force. [0003] In base formation methods such as Figure 8 , 9 As shown, the foundation body 1 is provided with steel reinforcements 3 around the deep foundation body 2 . The reinforcements 3 extend horizontally and obliquely radially from the foundation body 2 , and a plurality of reinforcements are arranged at predetermined intervals in the axial direction, and they are all fixed in the surrounding natural foun...
