2. Description of the Related Art A pile driving apparatus currently used is a crane mounted on a pile driving work vessel, a hammer and piles are mounted together, and the pile driving work vessel is moved to move the piles to a driving position. The fine adjustment of the pouring position is centered at the pouring position while turning the crane and raising and lowering the crane boom.
This device lacks accuracy in centering at the setting position because the pile driving ship sways due to waves. This is because, when the pile driving work ship sways, a long crane boom oscillates, and the piles hung on the crane boom sway. In particular, there are many piles that are placed on the seabed and have a length of about 80 meters, and it is extremely difficult to center accurately because long piles sway. Furthermore, there is a drawback that the centering work requires a long time.

Therefore, even if the pile driving work vessel 5 is shaken by a wave, the pile 4 can be prevented from swaying. The present inventors actually manufactured this device and placed the pile 4 on the seabed. However, this device was not so efficient and could not be accurately centered and the piles 4 could be driven. The reason is that the crane 1 and the telescopic boom 3 are used for fine adjustment for centering the pile 4. This device can extend and retract the telescopic boom 3 to make fine adjustments in the Y direction of the piles 4, but it is necessary to rotate the crane 1 for fine adjustments in the X direction. Difficult to do.

The pile driving device for driving a pile on the seabed according to the present invention has the following excellent features. There is a feature that the fine adjustment range for positioning the piles is widened so that the piles can be accurately positioned easily, accurately, and efficiently in a short time. This is because the telescopic cylinder can be projected from the pile driving work vessel for a long time, and the pile driving work vessel can be remarkably approached to the quay and the like. The telescopic cylinder, the rear end of which is connected to a rotatable turntable and the middle of which is supported by a support boom, can stably project long from the pile driving work ship and hold the pile. Therefore, the adjustment range between the pile driving work ship and the pile is wide, the moving range of the pile driving work ship is reduced, and the pile can be accurately positioned.
Furthermore, since the positioning means is arranged on the port side of the pile driving work ship, the pile driving work ship can be brought extremely close to the quay or the like and the piles can be finely adjusted and positioned.

The structure is simple and can be manufactured at low cost. The pile driving device for driving a pile on the seabed of the present invention connects the telescopic cylinder to a pile driving work ship so that the telescopic cylinder can rotate in a horizontal plane, and horizontally supports the telescopic cylinder to support the telescopic cylinder. This is because the Y-direction position can be adjusted and the telescopic cylinder can be rotated to adjust the X-direction position. The telescopic cylinder, which is rotatably arranged on the pile work boat in the horizontal plane, can be mounted on the pile work boat with an extremely simple structure in which the rear end is connected to the rotary table and the lower surface is supported by the support boom. Unlike the conventional pile driving device, it is not necessary to mount a heavy rail support or the like on the pile driving work ship so as to be able to move in parallel. Further, it is not necessary to provide a holder support so that it can be moved to this rail support. This is because the extensible cylinder can be expanded and contracted and rotated to finely adjust the XY directions for holding the pile.
