In this case, first, in excavation of the vertical hole, the upper end of the screw auger 5f is gripped by the chuck device of the auger driving device 5 pulled up to the upper part of the leader 2, and the rope 20 is operated by the operation of the winch 21 while rotating the screw auger 5f. The auger driving device 5 is extended while the screw auger 5f is pushed in with another rope or the like as necessary. After the drilling operation, in the case of a rotary type leader, the leader 2 is rotated 90 degrees about its axis (in the case of a fixed type two-sided leader, the pile driver is moved), and the guide member 4b is With the hammer device 6 installed, a pile driving operation is performed.

う。[0009] As shown in FIG. 9, in a general-scale pile driver, a guide member 4 a (a rail diameter φa and a rail width Wa are large) to which a large-sized working device with a large output can be attached;
Guide member 4b (rail diameter φ
b and the rail width Wb are small) are set as standard readers. Thus, the guide member 4
The reason why the sizes of a and 4b are provided for the large working device and the small working device is that, in order to prevent the pile driver body 1 from overturning, in general, the main body 1 is attached to the leader 2 and the leader 2. This is because the ability to support a working device is limited by the size of the pile driver. When drilling in hard ground in pile driving work, a large digging force is required. Therefore, a large output large auger driving device 5 guided by a large guide member 4a is used. In the case of (1), a pile having a diameter substantially equal to the hole diameter is used as a pile to be buried in the excavated vertical hole, and the driving force of the pile is small, so that the pile is guided by the small guide member 4b as the hammer device 6. The pile is driven by using a small hammer device 6.

(See FIG. 2 (B)) is mounted on the small guide member 4b to perform a vertical hole excavation work, and it is necessary to increase the driving force of the pile in order to use a pile having a diameter larger than the excavated vertical hole. Therefore, a large hammer device is mounted on the large guide member 4a to drive the pile.

打作業装置は使用できない。The pile driving operation includes not only the vertical driving of a vertical pile but also the vertical driving of a leader by inclining piles as a pile driving operation mainly performed on a ship. However, such an oblique pile driving operation is performed by the cylindrical rail 4
If the mounting is performed using a reader having guide members 4a and 4b of c and 4d, the mounting portions 5a and 6a
c, 4d, the cylindrical rail 4
It is not possible to use a leader having c and 4d and a pile driving device for vertical piles having mounting portions 5a and 6a of the arc-shaped slide portions 5s and 6s corresponding thereto.

Vibration causes repeated noise between the mounting portions 5a, 6a and the rails 4c, 4d to generate noise, and the mounting portions 5a, 6a and the rails 4c, 4d are worn away. A non-vibration type pile driving device having attachment portions 5a and 6a having cylindrical rails 4c and 4d and arc-shaped slide portions 5s and 6s cannot be used as the device.

用意する必要がある。Therefore, in order to perform such slanted pile driving or to enable the use of the vibratory pile driving device, in addition to the standard leader 2 having the cylindrical rails 4c and 4d, the leader is inclined. Even if the mounting part of the working device is prevented from coming off the rail, a leader for slanted pile driving with a guide member with a structure and a roller type mounting part that can absorb vibration and a guide member with a structure are provided. It is necessary to prepare various dedicated readers, such as a dedicated reader for a vibratory pile driving device.

業能率が悪いという問題点もあった。In recent years, the size of the pile driver has also been increasing, and the guide members 4a and 4b can be both large in some cases. In this case, however, a large and small guide such as a conventional leader is used. According to the configuration in which the members 4a and 4b are fixedly provided, two sets of the large auger driving device 5 or the large hammer device 6 cannot be mounted on the reader 2 at the same time. In addition work,
After raising the auger driving device 5 or the hammer device 6, the next divided auger or pile must be suspended and suspended in the same auger driving device 5 or the hammer device 6 to perform the work. there were.
