It should be understood that 64 precast piles 12 can be placed in the pile piling area 7, so that the pile repairing can be performed after the pile driving ship finishes driving eight groups, and the construction time is saved. The U-shaped cross sections at the two sides of the bracket 11 are opposite to the side of the ship body 1, so that the transportation ship is convenient to repair piles close to the side of the ship; and simultaneously, the double-hook crane 5 is convenient to take and put.

The piling ship is provided with a pipe pile piling area 7, and can store the components such as the positioning pile 9, the precast pile 12 and the like, thereby saving the construction time and facilitating the taking and placing of the double-hook crane 5. The cross sections of the positioning piles 9 and the precast piles 12 are round, so that the precast piles are easy to roll; the bracket 11 can limit the rolling range of the positioning pile 9 and the precast pile 12, and reduces the probability of the situation that the positioning pile 9 and the precast pile 12 roll to damage other equipment and roll out of the picking and placing range of the double-hook crane 5 due to shaking of a piling ship.

As shown in fig. 2, in some embodiments, a piling component storage area 8 is also included; the piling component storage area 8 is arranged on the deck of the ship body 1; the pile member storage zone 8 is located on the side remote from the outriggers 13.

The main hook 55 is a gable hook, the main hook 55 of the gable hook can hoist the precast pile 12 on one side, and the other side is connected with a pile hammer; when the pile driving device is lifted, the precast pile 12 and the pile driving hammer are lifted at the same time, so that the construction efficiency of the pile driving ship is improved.

Through the double-hook arrangement of the main hook 55 and the auxiliary hook 56, not only can multi-point hoisting be carried out simultaneously, but also the translation and turnover functions of the precast pile 12 can be realized, and the construction efficiency of a piling ship is improved.

In some embodiments, the laser positioning device is further included; the laser positioning device is arranged on the pile gripper 6; the pile hammer and the double-hook crane 5 can be clamped.

For example, when the double hook crane 5 lifts up the precast pile, two hooks of the main hook 55 can be simultaneously used for clamping with the pile hammer; when piling is completed, the two hooks of the main hook 55 can be opened and detached from the piling hammer.

The laser positioning device can accurately position the pile center of the precast pile 12, and monitors whether the precast pile 12 is inclined or not in real time when a pile driving hammer is used for driving.

s230: detecting the sinking position of the precast pile 12;

It should be understood that if the position of the sinking of the precast pile 12 does not deviate from the preset precast pile position, the sinking of the precast pile 12 is continued. In addition, because the pile clasping devices 6 are in one-to-one correspondence with the precast pile positions, the pile clasping devices 6 can be positioned by accurately positioning the precast piles 12.

In some embodiments, one end of the precast pile 12 is self-contained with a pile driving head, without additional installation; in other embodiments, where there is no pile driving head at one end of the precast pile 12, it is desirable to install the pile driving head at one end of the precast pile 12 before the double hook crane 5 places the precast pile 12 on the pile gripper 6.

As shown in fig. 7, in some embodiments, the outrigger 13 is a hydraulic outrigger including a hydraulic device and a bracket; one end of the bracket is fixedly connected with the ship body 1; during piling operation, the support can be opened through the hydraulic device, and the precast pile 12 is placed above the pile gripper 6 through the double-hook crane 5, so that the precast pile 12 penetrates through the pile gripper 6 until the pile head part of the precast pile 12 contacts the sea floor to lock, and pile feeding is completed.

According to the method, the double-hook crane 5, the outriggers 13 and the pile gripper 6 are controlled simultaneously, so that the precast piles 12 are accurately positioned at the preset precast pile positions, and meanwhile, the pile is fed to solve the problem of low construction efficiency of a piling ship.

The hull 1 is driven into the construction area, and in some embodiments, is positioned into the construction area by GPS mounted on the hull 1, and the hull 1 is towed into the construction area by a tow boat. In the towing process, the positioning pile 9 is not connected with the trolley positioning equipment 4, and after the positioning pile 9 reaches a construction water area, the positioning pile 9 is connected with the trolley positioning equipment 4 through a floating crane.

As shown in fig. 2, two trolley positioning devices 4 can be selected and respectively placed at the positions of the ship body 1 close to the bow and the stern; the positioning of the ship body 1 is more accurate.

When the ship is moved, the control trolley positioning equipment 4 lifts the positioning pile 9 and uses a positioning device to fix the positioning pile; the anchoring equipment 2 and the mooring equipment 3 are controlled to loosen the connection with the ship body 1, the ship body 1 is pulled to move to the next pile position through the oil cylinder, and then the positioning pile 9 is lowered to the seabed by the control trolley equipment; the mooring device 2 and the mooring device 3 are controlled again to tighten the connection with the hull 1.

According to the method, the anchoring equipment 2, the mooring equipment 3 and the trolley positioning equipment 4 are controlled by the positioning controller 10, so that the positioning accuracy can be improved, the probability of repeated positioning due to positioning deviation of the piling ship is reduced, and the construction efficiency of the piling ship is further improved.

In some embodiments, the hull 1 is driven to displace transversely or longitudinally according to a preset construction route; the preset construction route is an S-shaped route.

As shown in fig. 8 to 9, in order to facilitate site construction and to realize simultaneous operation of multiple vessels, the hull 1 may adopt two modes of lateral displacement and longitudinal displacement, respectively. The ship body 1 can transversely or longitudinally displace according to the S-shaped route, can move more quickly and improves the construction efficiency of the piling ship.

s340: the precast pile 12 is driven to a preset depth by a pile driving hammer.

It will be appreciated that in some embodiments, draft measuring devices and inclinometers may also be optional to monitor whether the hull 1 is held horizontally, reducing the chance of affecting pile accuracy due to buoyancy of the hull 1. When piling is completed, the outriggers 13 are retracted by hydraulic means. The position of the preset pile core and the preset depth are determined according to a construction drawing designed by a designer.

The method is characterized in that the precast pile 12 is positioned through the pile gripper 6 and the overhanging bracket 13, and then whether the precast pile 12 is inclined or not is monitored in real time when a pile hammer is driven through a laser positioning device.
