あった。Recently, devices for press-fitting and pulling out good piles using static force using hydraulic pressure have been provided. Only one set of hydraulic cylinders is known to be available.140Therefore, there are three types of hydraulic cylinders: the operation of clamping the P pile with the pile clamping member, the expansion and contraction operation of the hydraulic cylinder O, the pile scale releasing operation of the pile clamping member, and the pile clamping operation. Press-in of S-material piles,
Since the expansion and contraction of the hydraulic cylinder to return to the pulled-out position is repeated as one cycle, the pile press-in and pull-out operations are intermittent. The same amount of time as the 1° pile press-in and pull-out pipe must be used to prepare the pile for press-in and pull-out, resulting in poor work efficiency. On the other hand, when a pile is press-fitted into the ground, it is thought that there are three positive resistances of the pile: cross-sectional resistance at the tip of the wire, resistance at the connecting part, and frictional resistance around the pile O. Resistance is especially high in clayey soil
In this case, it is known that the time required to stop the pile press-in increases in direct proportion to the time required to stop the pile press-in.Therefore, with the conventional 0 equipment as mentioned above, the pile press-in operation can only be performed intermittently.
The longer the preparation time for the press-fitting operation, the greater the resistance.
However, there were drawbacks such as the inability to smoothly press-in the piles.

In addition, the pile press-in and pull-out work can be carried out efficiently, and the static force caused by hydraulic pressure can be concentrated on the cross-sectional resistance at the tip of the pile by reducing the peripheral friction resistance of the pile and the connecting sum resistance. I can do it,

The p pile Pt- may be press-fitted into the ground by the pull of the hydraulic cylinder 1 reef. A reaction force pile clamping device 3 may be provided for each, and the reaction force pile clamping device C may be operated alternately to allow the piles to run on their own, or the platform may be placed on the ground. . Furthermore, the arm 13 may be supported by a crane or the like. Pile press-in and pull-out mechanism 11, 1lt - By adding more in the front-back direction, it is also possible to press in multiple piles P of 2 or more into the ground at the same time and pull them out from the ground. . Further, the pile holding portion 22 may be operated by a mechanism other than a hydraulic cylinder. The present invention can be modified without departing from its basic technical concept.

行うことができる等の利点がある０As is clear from the above, according to the present invention, the press-fitting of the pile and the static force of the puller hydraulic pressure are used, so vibration and noise can be prevented. In addition, since the piles are continuously pressed into the ground or pulled out from the ground, work efficiency can be improved, and the frictional resistance around the piles and the wear of delayed setting areas can be improved.
It has the advantage of reducing lA resistance, allowing the static force caused by hydraulic pressure to be concentrated on the cross-sectional resistance at the tip of the pile, and making it possible to perform pile O press-fitting work smoothly.
