隘であり作業がはかどらない欠点がある。Therefore, it is necessary to strengthen the existing foundation by increasing the grain size. As shown in Figure 5, this grain-enhancing work involves digging beneath the foundation of the structure and press-fitting one or more piles (B) to a sufficient depth along the existing piles (A)↑ A thick-walled steel pipe with a length of about 1 m and a diameter of about 60 to 50 CrrL was used as the antibody, and a jack (c) was inserted between the top of the pipe and the lower surface of the foundation of the structure, and the steel pipe was press-fitted into the ground. The required depth is achieved by sequentially adding layers by welding. However, in this method, a steel pipe of a predetermined length 1
Each time a book is press-fitted, it is necessary to remove the jack already installed under the building foundation and reinstall it under the next foundation. Furthermore, in this method, new piles are press-fitted where existing piles are, so the work area is extremely narrow and the work cannot be completed smoothly.

合して昇降しながら回転するようになっている。At the lower end of the sylanger 7 of the jack 4, a chuck 9 to be engaged with the top of the antibody is rotatably attached to the sylanger 7, for example, via a thrust pairing 10. This chuck 9 has an engaging protrusion 11 to be engaged with the head of the pile body a, and is formed as a single spur gear having toothed edges on the circumferential surface. This tooth edge 12 is engaged with a pinion 14 extending in the vertical direction and rotated via a hydraulic motor 16 provided on the base 1, so as to rotate at a low speed (for example, 24 times/min). That is, as shown in FIG.
The vertical shaft 17, which is rotated through the shaft 5.16, is supported by upper and lower bearings 18 and 19 whose upper and lower ends are protruded from the support shaft, and a long pinion 14 is fitted onto the shaft. The chuck 9 engages the teeth 12 on its circumferential surface with the pinion 14 and rotates while moving up and down.

It is engaged with the notch 20 provided at the top of the. The hydraulic force 13 is driven to rotate the pile body a, the jack 4 is operated to lower the plunger 7, and the multiplier of the structure is used as a reaction force to press the antibody into the ground while rotating it. Continue pressing until the top of pile a is slightly exposed on the ground surface. After completing the specified press-fitting, the lr sylanger 7 is raised, the next pile body a is placed on top of the previously press-fitted antibody a, and after welding the periphery of the placement part, the chuck 9 is attached to the upper pile. The antibody is engaged with the notch 20 at the top of the body a, and the rotational press-fitting operation of the antibody is performed again. This operation is repeated in sequence, and when the lowest end of the connected piles a reach the supporting ground or reach a predetermined depth, the entire device is moved and removed, and the press-in A fixing material is inserted and fixed between the top end of the antibody and the lower surface of the base of the construct, and the excavated portion is backfilled to complete the work.

鋼管の頂面に切込部を形成して使用することができる。As explained in detail above, according to the present invention, compared to the conventional construction method in which a jack is fixed to the lower surface of the structure foundation at each position of pile body press-fitting and antibodies are press-fitted in one wooden block, Since the jack 4 is held fixed on the base 1, there is no need to attach or remove the jack every time a predetermined length of antibody is press-fitted, and since the antibody is press-fitted while being rotated, the press-fitting speed is significantly increased. , work efficiency can be greatly improved compared to conventional construction methods. Note that the antibody can be used by forming a notch on the top surface of a conventional steel pipe.
