[0024] Example:

[0025] like Figures 1 to 4As shown, this utility model proposes a guided positioning and pile driving system for underwater full-casing cast-in-place piles, including a steel casing 5 and multiple auxiliary piles 1. A guide frame 4 is provided at the top of each auxiliary pile 1. The guide frame 4 serves as the working surface, supporting the total station 7 and guiding the steel casing 5 through limiting holes 6, while also providing the installation foundation for the entire system. Multiple limiting holes 6 are arranged linearly on the guide frame 4, serving to guide and limit the steel casing 5, preventing significant displacement during the initial sinking stage. A vibratory hammer 8, corresponding vertically to the limiting holes 6, is installed at the top of the steel casing 5. The vibratory hammer 8 generates vibration force that is transmitted to the steel casing 5, allowing it to sink smoothly into the foundation. The vibratory hammer 8 is a construction device used in geological exploration and infrastructure construction, primarily used to drive piles into soil or rock through vibration. It is commonly used in pile driving operations to help drive piles into harder soil or rock layers to ensure the stability of the structure. The guide frame 4 is also equipped with a pair of protective railings 9 that block the limiting hole 6. The protective railings 9 are set on the guide frame 4 to block the area around the limiting hole 6, which plays a safety protection role and prevents construction personnel or tools from falling from the edge of the guide frame 4.

[0026] Among them, such as Figures 1 to 3 As shown, the top of each auxiliary pile 1 is movably fitted with a steel clamp assembly 2 supporting the guide frame 4. The steel clamp assembly 2 holds the auxiliary pile 1 through the first arc-shaped clamping plate 21 and the second arc-shaped clamping plate 22, and is fixed with the first ear plate 23, the second ear plate 24 and bolts and nuts, supporting and fixing the guide frame 4. A total station 7 is placed on the upper surface of one end of the guide frame 4. The total station 7 is placed on the upper surface of one end of the guide frame 4 to monitor the position and verticality of the steel casing 5 in real time to ensure accurate pile driving. The total station 7 is a precision instrument used to measure distance, angle, and coordinate geographic data, and is widely used in surveying, engineering surveying, and construction. It combines the technology of electronic distance measuring instruments, electronic theodolites, and computer processing systems, and can efficiently measure angles and distances and calculate the three-dimensional coordinates of points. Several positioning holes 41 are opened on the guide frame 4, and the threaded rods 32 on the steel clamp assembly 2 are inserted into them, and the guide frame 4 is fixed to the steel clamp assembly 2 with the third nut 33.

[0027] Secondly, such as Figures 1 to 3As shown, the steel clamp assembly 2 includes a first arc-shaped clamping plate 21 and a second arc-shaped clamping plate 22 that interlock. The first arc-shaped clamping plate 21 and the second arc-shaped clamping plate 22 cooperate to clamp the auxiliary pile 1, forming the main body of the steel clamp assembly 2 and providing a supporting foundation for the guide frame 4. The second arc-shaped clamping plate 22 and the first arc-shaped clamping plate 21 cooperate to clamp the auxiliary pile 1, together forming the main body of the steel clamp assembly 2 and supporting the guide frame 4. Both ends of the first arc-shaped clamping plate 21 and the second arc-shaped clamping plate 22 are fixedly connected to corresponding first ear plates 23 and second ear plates 24. The first ear plates 23 are fixed to the ends of the first arc-shaped clamping plate 21 and the second arc-shaped clamping plate 22, allowing the second bolt 27 to pass through. The second bolt 27 and the second nut 28 work together to connect and fix the first arc-shaped clamping plate 21 and the second arc-shaped clamping plate 22. The second ear plate 24 is fixed to the ends of the first arc-shaped clamping plate 21 and the second arc-shaped clamping plate 22, through which the first bolt 25 passes. The first bolt 25 and the first nut 26 reinforce the connection between the first arc-shaped clamping plate 21 and the second arc-shaped clamping plate 22, and at the same time provide a clamping position for the clamping sleeve assembly 3.

[0028] In addition, such as Figures 1 to 3 As shown, a pair of first ear plates 23 are provided with second bolts 27. The second bolts 27 pass through the pair of first ear plates 23 and are tightened with second nuts 28 to achieve the initial connection and fixation of the first arc-shaped clamping plate 21 and the second arc-shaped clamping plate 22. The end of the second bolt 27 is screwed with a second nut 28 that clamps the first ear plate 23. The second nut 28 is screwed onto the end of the second bolt 27. By tightening the first ear plate 23, the second bolt 27 completes the connection and fixation of the first arc-shaped clamping plate 21 and the second arc-shaped clamping plate 22. A pair of second ear plates 24 are provided with first bolts 25. The first bolts 25 pass through the pair of second ear plates 24 and are tightened with first nuts 26 to further fix the first arc-shaped clamping plate 21 and the second arc-shaped clamping plate 22 to the auxiliary pile 1. The end of the first bolt 25 is screwed with a first nut 26. The first nut 26 is screwed onto the end of the first bolt 25. By tightening, the first bolt 25 fixes the first arc-shaped clamping plate 21 and the second arc-shaped clamping plate 22.

[0029] It is worth noting that, such as Figures 2 to 4As shown, each steel clamp assembly 2 is equipped with a fixing mechanism that locks into the positioning hole 41. The fixing mechanism includes a retaining sleeve assembly 3 that is snapped onto the second ear plate 24. The retaining sleeve assembly 3 is snapped onto the second ear plate 24 and, through a threaded rod 32 inserted into the positioning hole 41 of the guide frame 4 and engaging with a third nut 33, secures the guide frame 4 to the steel clamp assembly 2. The steel clamp assembly 2 has a fixing hole 31 for the first bolt 25 to pass through, ensuring that the first bolt 25 can pass smoothly and secure the retaining sleeve assembly 3 to the steel clamp assembly 2. The top of the retaining sleeve assembly 3 is fixedly connected to a threaded rod 32 that passes through the positioning hole 41. The threaded rod 32 is also located on the steel clamp assembly 2, allowing the first bolt 25 to pass through smoothly and secure the steel clamp assembly 2. A third nut 33 is screwed onto the threaded rod 32 to lock the guide frame 4. The third nut 33 is screwed onto the threaded rod 32 and, by tightening, locks the guide frame 4, thus fixing the guide frame 4 onto the steel clamp assembly 2.

[0030] In this embodiment, when using the underwater full-casing cast-in-place pile guiding and positioning pile driving system, the auxiliary pile 1 is first driven into the foundation of the construction water area as the basic support for the entire system. Then, the first arc-shaped clamping plate 21 and the second arc-shaped clamping plate 22 of the steel clamp assembly 2 are respectively attached to the top two sides of the auxiliary pile 1, so that they hold the auxiliary pile 1 together. At this time, the first ear plates 23 and the second ear plates 24 at both ends of the first arc-shaped clamping plate 21 and the second arc-shaped clamping plate 22 are aligned with each other. The second bolt 27 is passed through a pair of first ear plates 23, and the second nut 28 is screwed on and tightened. At the same time, the first bolt 25 is passed through a pair of second ear plates 24, and the first nut 26 is screwed on and tightened, thus completing the fixation of the steel clamp assembly 2 on the auxiliary pile 1.

[0031] Next, the guide frame 4 is placed on the steel clamp assembly 2 on top of the multiple auxiliary piles 1, so that the steel clamp assembly 2 supports the guide frame 4. Before this, the ferrule assembly 3 is clamped onto the second ear plate 24 and locked using the first bolt 25 and the first nut 26. Then, the threaded rod 32 of the ferrule assembly 3 is passed through the positioning hole 41 on the guide frame 4, and the third nut 33 is screwed onto the threaded rod 32 and tightened, thereby fixing the guide frame 4 to the steel clamp assembly 2 and ensuring the stability of the guide frame 4.

[0032] Next, the total station 7 is placed on the upper surface of one end of the guide frame 4 to monitor the positioning and verticality of the subsequent steel casing 5. The steel casing 5 is initially positioned through the limiting holes 6 on the guide frame 4. The limiting holes 6 guide the steel casing 5 and prevent it from shifting significantly in the early stages of placement. At the same time, the guardrails 9 on the guide frame 4 provide safety protection to prevent construction personnel or tools from falling off the edge of the guide frame 4.

[0033] Finally, the vibratory hammer 8 is installed on top of the steel casing 5, and the vibratory hammer 8 is started. The vibration force generated by the vibratory hammer 8 is transmitted to the steel casing 5, causing the steel casing 5 to gradually sink into the foundation under the guidance and limiting action of the guide frame 4. During the pile driving process, the position and verticality of the steel casing 5 can be monitored in real time by the total station 7. If any deviation is found, it can be adjusted in time.

[0034] Through the cooperation of the above components, the system can achieve precise guidance, positioning and pile driving of the steel casing 5 on water, without the need to build a traditional steel platform. This effectively solves the problems of high cost, long construction period and limited space in the construction of scattered independent piles using traditional methods.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
