[0002] With the rapid development of port engineering construction and port building technology, coastal wharves are developing towards offshore and deep-water opening, and the tonnage of berthing ships is becoming increasingly larger. As a common wharf structure, high-pile wharves have been continuously optimized in their development process. Prestressed concrete pipe piles are widely used in the pile foundations of high-pile wharves because they have advantages such as good adaptability to complex geological conditions, meeting various load requirements, good seismic performance, and short construction period.

[0003] PHC pile top elevation is typically located at the mean tide level. In projects with regular diurnal tides (one rise and one fall per day), PHC piles cannot be constructed during high tide, leading to limited daily working time, low utilization of piling vessels, uncontrollable project schedules, and increased costs. Therefore, there is a need to develop a piling device for underwater pile driving that features a simple installation process and a robust structure. Utility Model Content

[0027] like Figures 1 to 3 As shown, in this embodiment, the present invention includes a pile body 1 for a pile driver. The pile body 1 is provided with a lifting lug 2, a jaw structure 3, and a vent hole 5. The upper end of the pile body 1 is provided with a first pad 6 and a first connecting port 7. The first pad 6 is disposed on the first connecting port 7 and has a first opening 8 communicating with the first connecting port 7. The lower end of the pile body 1 is provided with a second pad 9 and a second connecting port 10. The second pad 9 is disposed on the second connecting port 10 and has a second opening 11 communicating with the second connecting port 10. The pile body 1 is a steel pipe pile with a length of 1000mm and a thickness of 30mm; the first pad 6 and the second pad 9 are both 100mm thick and are both welded to the pile body 1.

[0028] During the installation of the pile driver, the jaw structure 3 is aligned with the bottom rail of the pile driving vessel. The pile body 1 of the pile driver is lifted and slowly slid in for installation, connecting the pile driver to the pile driving vessel. The jaw structure 3 is mainly used to control the coaxial perpendicularity of the pipe pile and the second connection port 10 and the smoothness of lifting, and to prevent the pipe pile from detaching from the second connection port 10 during pile slippage. Further, a rubber tube is threaded through the steel wire rope and tied to the pile lifting point. The friction between the rubber tube and the pile body is used to tighten the pipe pile, while also protecting the pile body. The pile body is manually pulled at both ends using a swaying rope. Further, the pipe pile is lifted using the auxiliary hook of the pile driving vessel, and the vessel is moved to the vicinity of the pile position using the vessel's positioning system. Finally, the clamp is opened... The pile driver adjusts the main and auxiliary hooks of the pile driving vessel to make the pipe pile stand upright in the second connection port 10 of the pile driver and fit the back plate, thus completing the connection between the pipe pile and the pile driver. Next, the positioning system of the pile driving vessel first determines the pile position and the angle of the pile frame. Then, two instruments on shore use the forward intersection method (tangent method) to adjust the pile position and the angle of the pile frame, thereby completing the precise positioning of the pipe pile. The small hook of the sling is untied, and under the guidance of the surveyors, the inclination of the pile frame is adjusted to accurately position the pile. After completion, the pipe pile is allowed to sink by itself. After the pile tip penetrates 2 to 3 meters into the soil, the sinking is paused for further correction and adjustment of the pile body. Then, the sinking continues until the pile body no longer sinks under its own weight. Based on this, press the hammer to make the pipe pile continue to sink under the gravity of the pile hammer; after the pipe pile stops sinking, keep the hull balanced, and require the pile hammer, the replacement hammer, the pile feeder and the pipe pile to be on the same axis. After checking that there are no problems, unhook the hook sling, open the pile gripper and the back plate, start the pile hammer to start hammering. When you start hammering, control the throttle a little and use a small stroke. Gradually increase the throttle until it meets the design requirements; finally, record 10 hammer blows as a set.

[0029] In contrast to the shortcomings of existing technologies, in this invention, the pile body 1 of the pile driver is connected to the pile driving vessel via the first connection port 7, and the pile body 1 is connected to the pipe pile via the second connection port 10. The lifting lug 2 is used for lifting the pile driver; the jaw structure 3 is used to cooperate with the bottom slide rail of the pile driving vessel, enabling the pile driver to be lifted smoothly and allowing control of the pile body's verticality during operation; the vent hole 5 is used to vent air during underwater pile driving, ensuring the quality of the underwater PHC pipe pile. Therefore, this invention can solve the problem of constructing PHC piles at water levels higher than the design pile top elevation, achieving underwater pile driving, increasing construction time, and solving the underwater pile driving quality problems such as eccentricity, tilting, and damage of PHC piles caused by traditional pile drivers. This invention also has the advantages of simple installation procedures and a stable structure.

[0030] In some embodiments, a first reinforcing structure is provided at the upper end of the pile body 1 of the pile driver. The first reinforcing structure is located in the first opening 8 and the first connecting port 7. The first reinforcing structure includes a first reinforcing plate 12, a first annular reinforcing plate 13, and a first inner ring reinforcing plate 15. The first annular reinforcing plate 13 is located at the bottom of the first connecting port 7, and the first inner ring reinforcing plate 15 is located on the inner wall of the first connecting port 7. The first reinforcing plate 12 is located in the first opening 8 and the first connecting port 7, and is disposed on the first annular reinforcing plate 13 and the first inner ring reinforcing plate 15. Specifically, by setting the first reinforcing plate 12, the first annular reinforcing plate 13, and the first inner ring reinforcing plate 15, transverse and longitudinal reinforcing ribs can be provided in the inner wall of the upper end of the pile body 1 of the pile driver, effectively improving the pile driver's resistance to hammering, reducing water pressure, and reducing torsional deformation.

[0031] In some embodiments, a second reinforcing structure is provided at the lower end of the pile body 1 of the pile driver. The second reinforcing structure is located in the second opening 11 and the second connecting port 10. The second reinforcing structure includes a second reinforcing plate 16, a second annular reinforcing plate 17, and a second inner ring reinforcing plate 18. The second annular reinforcing plate 17 is disposed at the bottom of the second connecting port 10, and the second inner ring reinforcing plate 18 is disposed on the inner wall of the second connecting port 10. The second reinforcing plate 16 is located on the second opening 11 and the second connecting port 10, and is disposed between the second annular reinforcing plate 17 and the second inner ring reinforcing plate 18. The second pad 9 has a connecting structure 19 on its lower end face. The connecting structure 19 has an inner limiting port reinforcing plate 20. The inner limiting port reinforcing plate 20 has an inner limiting port 21 that communicates with the second opening 11. The connecting structure 19 has a first outer ring reinforcing plate 22 and an outer guide portion 23 on its outer side. The first outer ring reinforcing plate 22 is disposed on the second pad 9. The outer guide portion 23 is located at the lower end of the connecting structure 19. The second pad 9 has a second outer ring reinforcing plate 25, which is disposed on the pile body 1 of the pile driver. Specifically, by setting the second reinforcing plate 16, the second annular reinforcing plate 17, and the second inner ring reinforcing plate 18, transverse and longitudinal reinforcing ribs can be set in the inner wall of the lower end of the pile body 1 of the pile driver, which effectively improves the pile driver's resistance to hammering, reduces water pressure, and reduces torsional deformation. In addition, when the second connection port 10 is connected to the pipe pile, the outer guide part 23 can play a guiding role, and the inner limiting port 21 can ensure the stability of the second connection port 10 when connected to the pipe pile, so that it is not easy to fall off.

[0032] In some embodiments, there are multiple lifting lugs 2, all located on the upper part of the pile body 1 of the pile driver and symmetrically arranged on both sides of the pile body 1. Specifically, there are four lifting lugs 2.

[0033] In some embodiments, there are multiple jaw structures 3, distributed on the upper and lower parts of the pile body 1 of the pile driver; each jaw structure 3 includes a jaw seat with jaws provided thereon, and the jaw seat is slidably fitted onto the bottom slide rail of the pile driving vessel via the jaws. Specifically, there are four jaw structures 3.

[0034] In some embodiments, there are multiple vent holes 5, which are symmetrically arranged on both sides of the pile body 1 of the pile driver. Specifically, there are two vent holes 5.

[0035] It should be noted that, in this utility model, for projects with regular diurnal tides (one rise and one fall daily), a pile driver is specifically designed to address the problem of constructing PHC piles at water levels higher than the designed pile top elevation. This design meets the operational requirements for underwater pile driving, enabling all-weather operation under tidal variations and significantly improving construction efficiency. When implementing underwater pile driving, this utility model solves key quality problems such as verticality and planar position deviations that are prone to occur in underwater PHC pile driving by setting the first connection port 7 and the second connection port 10 at the upper and lower ends of the pile driver.
