Abstract

PURPOSE:To perform nipping of the part, except an upper end part, of a pile by means of a chuck, to prevent oscillation of a pile during drive of a pile and pull-out of the pile, to effect drive of a pile even in a portion in the vicinity of a building, and to execute a work without needing a so wide space above the pile. CONSTITUTION:A vibration pile driver comprises a body 20 having an exciter 16, and a chuck 30 coupled to the lower side of the exciter 16 and vertically vibrated. A pile nipping part 30A of the chuck 30 is laid down in a direction crossing a vibration direction at right angles so that the pile nipping part is formed approximately in a C-shape in a plane view. A pile K is nipped by the pile nipping part 30A at a side apart from an outer peripheral surface 20a of the body 20.

1a is pulled in to lower the swing lever 75 and the movable teeth 67.
Is separated from the fixed tooth 66 as shown by the one-dot chain line in the figure, the upper end of the pile K is inserted between the fixed tooth 66 and the movable tooth 67, and then the cylinder 71 is actuated to move the piston. The rod 71a is projected. As a result, the swing lever 75 and the movable teeth 67 move to the positions shown by the solid lines in the figure, and the upper ends of the piles K are clamped by the fixed teeth 66 and the movable teeth 67, and the exciter 56 is operated in this state. Then, the pile K vibrates in the vertical direction together with the chuck 60, thereby reducing the frictional resistance between the pile K and the ground, and as a result, the pile K is driven into the ground by applying a downward load to the pile K. The pile K is pulled out from the ground by applying an upward pulling force to the pile K.

Under such a condition that the pile can be sandwiched just below the main body 50 and only at the upper end thereof, for example, when the pile is relatively long, the distance from the sandwiched portion (upper end) of the pile to the ground is long. Therefore, it is difficult to properly perform the work when pile driving / pulling work is performed, and it is difficult to perform the work properly. Since the outer peripheral portion of the main body 50 projects laterally from the sandwiching portion of the pile, the pile should be installed at a site close to a building or the like. Can't drive,
Since a space larger than substantially the entire length of the vibrating pile driver is required above the pile during pile driving / pulling work, it is not possible to perform pile driving / pulling work in an existing building or tunnel, for example. was there.

[Operation] In the vibrating pile driver according to the present invention configured as described above, the pile holding portion of the chuck is laid sideways, and the pile can be held laterally from the outer peripheral surface of the main body. Since it is possible, the chuck can also clamp parts other than the upper end of the pile. Therefore, for example, when driving a comparatively long pile into the ground, the distance from the sandwiching portion of the pile to the ground can be shortened by moving the sandwiching portion of the pile by the chuck in a stepwise manner from the lower or central portion. As a result, the pile does not easily swing, and the work can be performed properly.Because the main body can be located outside the building than the pile, it is possible to drive the pile into a part close to the building, etc. By sandwiching the middle part of the pile with a chuck, the height position of the entire vibrating pile driver will be low during pile driving / pulling-out work, so a large space above the pile is not required. Pile driving / pulling-out work can be performed in buildings, tunnels, etc.

When the pile K is clamped by the chuck 30 having such a structure, as shown by the solid line in FIG.
The piston rod 41a of the cylinder 41 is pulled in advance to separate the tip end portion of the swing lever 45 and the movable tooth 37 from the fixed tooth 36, and an appropriate portion (not limited to the upper end portion) of the pile K is used as the fixed tooth 36. It is inserted between the movable teeth 37 and then the cylinder 41 is actuated to move the piston rod 4
1a is projected. As a result, the swing lever 45 and the movable teeth 37 move to the positions shown by the alternate long and short dash line in the figure, and the specific portion of the pile K is sandwiched between the fixed teeth 66 and the movable teeth 67. When actuated, the pile K vibrates in the vertical direction together with the chuck 30, which reduces the frictional resistance between the pile K and the ground. As a result, the pile K is driven into the ground by applying a downward load to the pile K. In addition, the pile K is pulled out from the ground by applying an upward pulling force to the pile K.

As described above, in the vibrating pile driving machine 10 of this embodiment, the pile holding portion 30A of the chuck 30 is laid sideways, and the pile K is fixed to the outer peripheral surface 20a of the main body 20.
Since it can be clamped more laterally, the chuck 30 can also clamp parts other than the upper end of the pile K. Therefore, for example, when driving a relatively long pile into the ground,
If the gripping portion of the pile K by the chuck 30 is gradually moved upward from the lower portion or the central portion, the distance from the gripping portion of the pile K to the ground can be shortened, and as a result, the pile is less likely to swing. , Work can be done properly.

Further, since the main body 20 can be located outside the pile K from the building, it is possible to drive the pile into a portion close to the building or the like. Further, if the chuck 30 clamps the middle portion of the pile, the height position of the entire vibrating pile driving machine 10 is lowered during the pile driving / pulling-out work, so that a large space above the pile K is not required, and accordingly, For example, pile driving / pulling work can be performed in an existing building or in a tunnel.

FIG. 6 shows an example of another mode of the mounting portion used when the main body 20 and the chuck 30 are rotatably connected to each other. In this mounting portion 80, a first cylindrical body 83 having a mounting flange 82 is fitted to a support shaft 81 in a non-rotatable state, and a second cylindrical body 85 having a mounting flange 84 is attached to the above. It is attached to the support shaft 81 in a freely rotatable state. That is, the thrust bearing 86 is fitted to the opposing surfaces of the first cylindrical body 83 and the second cylindrical body 85, and the second cylindrical body 85 is further fitted.
Has an enlarged diameter portion 87 on the side of the flange 84. The enlarged diameter portion 87 has a thrust bearing 88 and an upper portion of the thrust bearing 88 that is not rotatable with respect to the support shaft 81, but has a large diameter portion 87. Cylindrical body 8 for locking with the inner surface being rotatable
9 is inserted. As a result, in the mounting portion 80, the first cylindrical body 83 and the second cylindrical body 85 are mounted on the support shaft 81 in a mutually rotatable state. Further, each flange 82, 84 is formed with a mounting hole 90 as shown in FIG. 6a.

By using this mounting portion 80, the main body 20 and the chuck 30 can be connected in a rotatable manner. That is, one flange 82 (84) is fixed to the side of the pile 30 of the chuck 30 by a suitable fixing means such as a bolt, and the other flange 84 (84) is similarly fixed by a suitable fixing means. It should be fixed to the side. Although not shown in the figure, an appropriate positioning means or a forced turning means such as a hydraulic motor, an electric motor and a gear mechanism is provided between the first cylindrical body 83 and the second cylindrical body 85 in the mounting portion 80. It is also possible to intervene.

As can be understood from the above description, according to the vibrating pile driving machine of the present invention, since the chuck can clamp the portion other than the upper end portion of the pile, the pile driving / pulling operation can be performed. It is extremely advantageous in practical use that it is possible to drive the piles hard to swing, and it is possible to drive the piles into the parts close to buildings, etc., and further, the above work can be performed without requiring a large space above the piles. Is obtained.
