Description

Technical Field

[0001] This application belongs to the field of offshore wind power piling construction technology, specifically relating to a piling positioning guide frame and construction method. Background Technology

[0002] With the implementation of the national dual-carbon development goals, offshore wind power development in deep-sea areas has become a trend. Currently, pile foundations remain the primary foundation type for offshore wind power. During offshore pile foundation driving, positioning guide frames are required for the installation and positioning of the pile foundations to facilitate precise construction. Existing positioning guide frames mainly use an auxiliary pile plus a positioning frame for construction, with the guide cylinders installed underwater near the mud surface. After the pile foundation enters the water, it is manually or by unmanned underwater vehicle (UAV) to guide and insert the guide cylinder, a complex and time-consuming operation. Therefore, there is a need to develop a pile driving positioning frame that facilitates pile foundation insertion and positioning, allowing the pile foundation to be positioned before entering the water, reducing underwater operations and improving pile driving accuracy and efficiency. Summary of the Invention

[0003] The purpose of this application is to provide a pile driving positioning guide frame and construction method, which facilitates the penetration and positioning of pile foundations, enabling the pile foundations to be positioned before entering the water, reducing underwater operations, and improving pile driving accuracy and efficiency.

[0004] In a first aspect, embodiments of this application provide a piling positioning guide frame, which includes: a positioning frame, a fixed foundation, a support platform, a fixed guide platform, and a sliding guide platform;

[0005] The fixed base is connected to one end of the positioning frame. The support platform and the fixed guide platform are both fixedly connected to the positioning frame. The sliding guide platform is slidably connected to the positioning frame. The support platform and the fixed guide platform are distributed at intervals along the axial direction of the positioning frame. The sliding guide platform is located between the support platform and the fixed guide platform.

[0006] A drive motor is provided on the support platform. The sliding guide platform includes a connected sliding bracket and an upper positioning cylinder. The sliding bracket is slidably connected to the positioning frame and is also connected to the drive motor. The drive motor is configured to drive the sliding bracket to slide relative to the positioning frame. The fixed guide platform includes a connected fixed bracket and a lower positioning cylinder. The fixed bracket is fixedly connected to the positioning frame. The upper positioning cylinder is coaxial with the lower positioning cylinder and parallel to the axial direction of the positioning frame. The lower positioning cylinder is positioned below the sea level, and the upper positioning cylinder is positioned above the sea level.

[0007] Optionally, the piling positioning guide frame further includes an upper connecting frame and a lower connecting frame;

[0008] One end of the upper connecting frame is detachably connected to the upper positioning cylinder, and the other end of the upper connecting frame is detachably connected to the sliding bracket;

[0010] Optionally, there are multiple upper connecting frames, and the multiple upper connecting frames have different sizes. One of the upper connecting frames is detachably connected to the sliding bracket.

[0011] The number of lower connecting frames is multiple, and the multiple lower connecting frames are of different sizes. One of the lower connecting frames is detachably connected to the fixed bracket.

[0012] Optionally, the drive component is a motor, which is connected to a traction rope. The traction rope is connected to the sliding bracket, and the drive component drives the traction rope to move relative to the positioning frame, so that the traction rope drives the sliding bracket to slide relative to the positioning frame.

[0013] Optionally, the output end of the motor is connected to a lead screw, and the extension direction of the lead screw is parallel to the axial direction of the positioning frame. A slider is provided on the lead screw, and the traction rope is connected to the slider.

[0014] Optionally, the output end of the drive motor is connected to a rope winder, and part of the traction rope is wound around the rope winder. The axis of the rope winder intersects with the axis of the positioning frame and forms an angle.

[0015] Optionally, the driving component is an electric hoist, which is connected to the sliding bracket to drive the sliding bracket to move relative to the positioning frame.

[0016] Optionally, the upper positioning cylinder is connected to an upper flared structure at its upper end, and the lower end of the upper flared structure is aligned with the upper positioning cylinder; the lower positioning cylinder is connected to a lower flared structure, and the lower end of the lower flared structure is aligned with the lower positioning cylinder; the openings of the upper and lower flared structures are both upward and coaxial.

[0017] Optionally, the positioning frame comprises multiple uprights and multiple crossbeams. The lower ends of the uprights are connected to a fixed foundation. The multiple uprights are spaced apart. The lines connecting the projections of the multiple uprights along the axis of the positioning frame form a closed shape. Along the circumferential direction of the closed shape, at least two adjacent uprights are provided with crossbeams, and the crossbeams connect two uprights respectively. The axis of the crossbeams is perpendicular to the axis of the uprights.

[0018] The column is connected to a hoisting assembly, which facilitates the transportation and movement of the entire positioning guide frame.

[0019] Optionally, the number of columns is four, and the line connecting the projections of the four columns along the axis of the positioning frame forms a square;

[0020] Alternatively, the number of columns is three, and the line connecting the projections of the three columns along the axis of the positioning frame forms an equilateral triangle.

[0021] Optionally, the fixed foundation consists of a single-cylinder multi-compartment cylindrical foundation or multiple single-cylinder single-compartment cylindrical foundations, with the multiple single-cylinder single-compartment cylindrical foundations simultaneously connected to one end of the positioning frame.

[0022] Optionally, the positioning frame is provided with a sliding groove, and the sliding bracket is connected to a pulley, the pulley being embedded in the sliding groove so that the sliding bracket is slidably connected to the positioning frame.

[0023] Secondly, embodiments of this application provide a construction method applied to the piling positioning guide frame described in any one of the first aspects above, the construction method comprising:

[0024] The piling positioning guide frame is transported to the construction sea area, and the position of the sliding guide platform relative to the positioning frame is adjusted according to the water depth so that the sliding guide platform is above the sea level;

[0025] The piling positioning guide frame is placed on the seabed surface by hoisting, and the fixed foundation is installed in place by suction installation.

[0026] One or more steel piles to be installed will be driven into the seabed sequentially through the upper positioning cylinder and the lower positioning cylinder. After the steel piles have sank to the bottom under their own weight, the pile hammer and pile driver will be installed and the pile driving construction will begin.

[0027] Optionally, one or more steel piles to be installed are sequentially driven into the seabed through the upper positioning cylinder and the lower positioning cylinder. After the piles have settled under their own weight, the pile hammer and pile driver are installed, and pile driving construction begins, including:

[0028] One or more steel piles to be installed will be driven into the seabed sequentially through the upper positioning cylinder and the lower positioning cylinder;

[0029] After the steel pile has sank under its own weight, the sliding guide platform is adjusted by the drive component to move the sliding guide platform downward until the sliding guide platform is away from the end of the steel pile that is above sea level.

[0030] The installation of the pile hammer and pile driver began, and pile driving construction commenced.

[0031] In this embodiment, since the fixed foundation is connected to one end of the positioning frame, when using the piling positioning guide frame, the fixed foundation can be placed on the seabed surface below the sea level to fix the positioning frame, ensuring its stability. Additionally, the support platform and the fixed guide platform are both fixedly connected to the positioning frame, while the sliding guide platform is slidably connected to the positioning frame. The support platform and the fixed guide platform are spaced apart along the axial direction of the positioning frame, with the sliding guide platform located between them. Therefore, force can be applied to the sliding guide platform, allowing it to slide relative to the axial direction of the positioning frame, thus changing its position relative to the positioning frame. Furthermore, a drive motor is installed on the support platform. The sliding guide platform includes a connected sliding bracket and an upper positioning cylinder. The sliding bracket is slidably connected to the positioning frame and connected to the drive motor. Therefore, the drive motor can move the sliding bracket, causing it to move the upper positioning cylinder relative to the positioning frame. In other words, by applying force to the sliding bracket with the drive motor, the sliding bracket moves relative to the positioning frame, thereby causing the upper positioning cylinder to move along the axial direction of the positioning frame. In addition, the fixed positioning component includes a connected fixed bracket and a lower positioning cylinder. The fixed bracket is fixedly connected to the positioning frame, and the upper and lower positioning cylinders are positioned opposite each other along the axial direction of the positioning frame. Therefore, when using the pile driving positioning guide frame, the fixed guide platform can be located below the sea level, and the sliding guide platform can be located above the sea level. That is, the fixed guide platform is below the sea level, and the sliding guide platform is above the sea level. Thus, when positioning the steel pile, the sliding bracket can be moved to a suitable position relative to the positioning frame by the drive motor. Then, the steel pile is first inserted into the upper positioning cylinder, which can then position the steel pile. Even if the steel pile penetrates below the sea level, part of the steel pile will still be located in the upper positioning cylinder. Thus, the upper positioning cylinder can ensure that the steel pile is stably positioned by the upper positioning cylinder when it is subjected to ocean currents or waves. Since the upper and lower positioning cylinders are opposite each other, the steel pile can enter the lower positioning cylinder.

[0032] In other words, by setting up a sliding guide platform and connecting the drive motor to the sliding guide platform, during piling, the steel pile can be hoisted to the piling positioning guide frame by a hoisting device, and the drive motor drives the sliding component to move, so that the upper positioning cylinder of the sliding component moves to a suitable position. Then, the steel pile is inserted into the upper positioning cylinder. The upper positioning cylinder is above the sea surface, so the upper positioning cylinder will not be affected by the ocean current or waves, and the steel pile is above the sea surface, so it is not affected by the ocean current or waves, which facilitates the steel pile to pass through the upper positioning cylinder. After the steel pile is driven into the sea, the steel pile is limited by the upper positioning cylinder. The upper positioning cylinder and the lower positioning cylinder are positioned opposite each other, so the steel pile is effectively limited, which facilitates the steel pile to penetrate into the lower positioning cylinder. The upper positioning cylinder and the lower positioning cylinder simultaneously limit the steel pile, which facilitates subsequent piling, thereby effectively improving the piling efficiency.

Detailed Implementation

[0040] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0041] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] Before explaining the piling positioning guide frame provided in the embodiments of this application, let's first describe the application scenario of the piling positioning guide frame provided in the embodiments of this application: During piling, the positioning cylinder of the piling positioning guide frame is located below the sea surface. The steel pile is driven into the sea surface, so that the steel pile is embedded in the positioning cylinder. The positioning cylinder positions the steel pile, and then the steel pile is driven into the seabed surface. However, in related technologies, when guiding the steel pile with the piling positioning guide frame, after the steel pile enters the sea surface, the flow of seawater or the movement of waves can cause the steel pile to shift in position, making it difficult for the steel pile to enter the guide cylinder, thus resulting in low piling construction efficiency.

[0043] like Figures 1 to 4 As shown, the piling positioning guide frame includes: a positioning frame 10, a fixed foundation 20, a support platform 30, a fixed guide platform 40, and a sliding guide platform 50.

[0044] A fixed base 20 is connected to one end of the positioning frame 10. A support platform 30 and a fixed guide platform 40 are both fixedly connected to the positioning frame 10. A sliding guide platform 50 is slidably connected to the positioning frame 10. The support platform 30 and the fixed guide platform 40 are spaced apart along the axial direction of the positioning frame 10. The sliding guide platform 50 is located between the support platform 30 and the fixed guide platform 40. A drive assembly 60 is provided on the support platform 30. The sliding guide platform 50 includes a connected sliding bracket 51 and an upper positioning cylinder 52. The sliding bracket 51 is slidably connected to the positioning frame 10 and is also connected to the drive assembly 60. The drive assembly 60 is configured to drive the sliding bracket 51 to slide relative to the positioning frame 10. The fixed guide platform 40 includes a connected fixed bracket 41 and a lower positioning cylinder 42. The fixed bracket 41 is fixedly connected to the positioning frame 10. The upper positioning cylinder 52 and the lower positioning cylinder 42 are coaxial and parallel to the axial direction of the positioning frame 10. The lower positioning cylinder 42 is used to be located below the sea level, and the upper positioning cylinder 52 is used to be located above the sea level.

[0045] In this embodiment, since the fixed foundation 20 is connected to one end of the positioning frame 10, when using the piling positioning guide frame, the fixed foundation 20 can be placed on the seabed surface below the sea surface to fix the positioning frame 10, ensuring its stability. Additionally, the support platform 30 and the fixed guide platform 40 are both fixedly connected to the positioning frame 10, and the sliding guide platform 50 is slidably connected to the positioning frame 10. The support platform 30 and the fixed guide platform 40 are spaced apart along the axial direction of the positioning frame 10, and the sliding guide platform 50 is located between the support platform 30 and the fixed guide platform 40. Therefore, force can be applied to the sliding guide platform 50, allowing it to slide relative to the axial direction of the positioning frame 10, thus changing its position relative to the positioning frame 10. In addition, a drive assembly 60 is provided on the support platform 30. The sliding guide platform 50 includes a connected sliding bracket 51 and an upper positioning cylinder 52. The sliding bracket 51 is slidably connected to the positioning frame 10 and is connected to the drive assembly 60. Therefore, the drive assembly 60 can drive the sliding bracket 51 to move, so that the sliding bracket 51 drives the upper positioning cylinder 52 to move relative to the positioning frame 10. That is, the drive assembly 60 applies force to the sliding bracket 51, so that the sliding bracket 51 moves relative to the positioning frame 10. In this way, the sliding bracket 51 can drive the upper positioning cylinder 52 to move along the axial direction of the positioning frame 10. In addition, the fixed positioning assembly includes a connected fixed bracket 41 and a lower positioning cylinder 42. The fixed bracket 41 is fixedly connected to the positioning frame 10. The upper positioning cylinder 52 is coaxial with the lower positioning cylinder 42 and parallel to the axial direction of the positioning frame 10. Therefore, when using the pile driving positioning guide frame, the fixed guide platform 40 can be positioned below the sea level, and the sliding guide platform 50 can be positioned above the sea level. That is, the fixed guide platform 40 is below the sea level, and the sliding guide platform 50 is above the sea level, thus enabling precise positioning of the steel pile. The drive assembly 60 drives the sliding bracket 51 to move relative to the positioning frame 10 to a suitable position. Then, the steel pile is first inserted into the upper positioning cylinder 52. The upper positioning cylinder 52 can then position the steel pile. Even if the steel pile penetrates below the sea surface, part of the steel pile will still be located in the upper positioning cylinder 52. Thus, the upper positioning cylinder 52 can ensure that the steel pile is stably positioned by the upper positioning cylinder 52 when it is subjected to ocean currents or waves. The upper positioning cylinder 52 is opposite to the lower positioning cylinder 42, so the steel pile can enter the lower positioning cylinder 42.

[0046] In other words, by setting up a sliding guide platform 50 and connecting the drive component 60 to the sliding guide platform 50, during piling, the steel pile can be hoisted to the piling positioning guide frame by a hoisting device, and the sliding component is moved by the drive component 60, so that the upper positioning cylinder 52 of the sliding component moves to a suitable position. Then the steel pile is inserted into the upper positioning cylinder 52. The upper positioning cylinder 52 is above the sea surface, so the upper positioning cylinder 52 will not be affected by the sea current or waves, and the steel pile is above the sea surface and will not be affected by the sea current or waves, which facilitates the steel pile to be inserted into the upper positioning cylinder 52. After the steel pile penetrates below the sea surface, the steel pile is limited by the upper positioning cylinder 52. The upper positioning cylinder 52 and the lower positioning cylinder 42 are positioned opposite each other, so the steel pile is effectively limited, which facilitates the steel pile to penetrate into the lower positioning cylinder 42. The upper positioning cylinder 52 and the lower positioning cylinder 42 simultaneously limit the steel pile, which facilitates subsequent piling and can effectively improve the piling efficiency.

[0047] It should be noted that, in this embodiment, the inner diameter of the upper positioning cylinder 52 is equal to the inner diameter of the lower positioning cylinder 42, and the axis of the upper positioning cylinder 52 is collinear with the axis of the lower positioning cylinder 42, that is, the axis of the upper positioning cylinder 52 and the axis of the lower positioning cylinder 42 are on the same straight line. Furthermore, in this embodiment, both the upper positioning cylinder 52 and the lower positioning cylinder 42 can be made of metal, and an anti-corrosion layer can be provided on both the upper positioning cylinder 52 and the lower positioning cylinder 42 to prevent them from easily rusting.

[0048] In addition, in this embodiment of the application, when driving piles, the steel piles are hoisted to the pile driving positioning guide frame by a hoisting device, and the steel piles are located above the sea surface, and the steel piles need to be driven into the seabed surface below the sea surface.

[0049] In addition, in this embodiment, a control component (not shown in the figure) can be installed on the support platform 30. The control component is electrically connected to the drive component 60. The control component controls the drive component 60, causing it to operate. This causes the drive component 60 to apply force to the sliding bracket 51, making the sliding bracket 51 slide relative to the positioning frame 10. That is, the sliding bracket 51 slides along the axis of the positioning frame 10. The sliding bracket 51 can then drive the upper positioning cylinder 52 to move along the axis of the positioning frame 10, adjusting the position of the upper positioning cylinder 52. The control component can be a programmable logic controller (PLC). The control component and the drive component 60 are electrically connected via wires, allowing the control component to send control signals to the drive component 60 to start or stop it. Alternatively, the control component can be other components with control functions, such as an electronic terminal with control functions, including but not limited to laptops and mobile phones. In this case, the control component and the drive component 60 can be connected via Bluetooth.

[0050] Furthermore, in this embodiment, the number of upper positioning cylinders 52 can be set according to actual needs. For example, there can be four upper positioning cylinders 52, which are spaced apart along the circumferential direction of the sliding bracket 51. Alternatively, there can be six upper positioning cylinders 52, which are spaced apart along the circumferential direction of the sliding bracket 51. That is, when there are multiple upper positioning cylinders 52, they are spaced apart along the circumferential direction of the sliding bracket 51. The specific number of upper positioning cylinders 52 is not limited in this embodiment.

[0051] Furthermore, the number of lower positioning cylinders 42 can be set according to actual needs. For example, there can be four lower positioning cylinders 42, which are spaced apart along the circumferential direction of the fixed bracket 41. Alternatively, there can be six lower positioning cylinders 42, which are spaced apart along the circumferential direction of the fixed bracket 41. In other words, when there are multiple lower positioning cylinders 42, they are spaced apart along the circumferential direction of the fixed bracket 41. The specific number of lower positioning cylinders 42 is not limited in this embodiment.

[0052] In addition, in this embodiment, the number of upper positioning cylinders 52 is equal to the number of lower positioning cylinders 42, and one upper positioning cylinder 52 corresponds to one lower positioning cylinder 42.

[0053] Furthermore, in this embodiment, the drive component 60 can be a drive component, which can be a servo motor or a stepper motor. The specific type of drive component is not limited in this embodiment.

[0054] Furthermore, in this embodiment, the number of driving components 60 can be set according to actual needs. For example, if there are two driving components 60, they can be connected at different positions on the sliding component to ensure that the sliding component is subjected to balanced forces during sliding, allowing it to slide smoothly. Alternatively, if there are four driving components 60, they can be connected at different positions on the sliding component to ensure that the sliding component is subjected to balanced forces during sliding, allowing it to slide smoothly. The specific number of driving components 60 is not limited in this embodiment.

[0055] In addition, in this embodiment, the drive assembly 60 can be bolted to the support platform 30. Of course, the housing of the drive assembly 60 can also be welded to the support platform 30. This embodiment does not limit the scope of the application.

[0056] In addition, in this embodiment, the edge of the support platform 30 may have a protrusion that protrudes from the positioning frame 10, and the drive component 60 may be disposed on the protrusion.

[0057] Additionally, in some embodiments, such as Figure 1 or Figure 2 As shown, the piling positioning guide frame also includes an upper connecting frame 70 and a lower connecting frame 80; one end of the upper connecting frame 70 is detachably connected to the upper positioning cylinder 52, and the other end of the upper connecting frame 70 is detachably connected to the sliding bracket 51; one end of the lower connecting frame 80 is detachably connected to the lower positioning cylinder 42, and the other end of the lower connecting frame 80 is detachably connected to the fixed bracket 41.

[0058] Since one end of the upper connecting frame 70 is detachably connected to the upper positioning cylinder 52, and the other end of the upper connecting frame 70 is detachably connected to the sliding bracket 51, when it is necessary to disassemble or replace the upper connecting frame 70, the upper connecting frame 70 can be directly separated from the sliding bracket 51 and the upper connecting frame 70 can be directly separated from the upper positioning cylinder 52, thus facilitating the replacement or maintenance of the upper connecting frame 70. Similarly, since one end of the lower connecting frame 80 is detachably connected to the lower positioning cylinder 42, and the other end of the lower connecting frame 80 is detachably connected to the fixed bracket 41, when it is necessary to disassemble or replace the lower connecting frame 80, the lower connecting frame 80 can be directly separated from the fixed bracket 41 and the lower connecting frame 80 can be directly separated from the lower positioning cylinder 42, thus facilitating the replacement or maintenance of the lower connecting frame 80.

[0059] It should be noted that the upper connecting frame 70 and the upper positioning cylinder 52 can be connected by bolts, making them detachably connected. Alternatively, the upper connecting frame 70 and the upper positioning cylinder 52 can also be detachably connected in other ways. For example, the upper connecting frame 70 can be connected with a buckle, and the upper positioning cylinder 52 can be provided with a matching slot or engaging piece. The upper connecting frame 70 and the upper positioning cylinder 52 can be detachably connected by engaging the buckle with the slot or engaging the buckle with the engaging piece. The specific connection method for the detachable connection of the upper connecting frame 70 and the upper positioning cylinder 52 is not limited in this embodiment. Similarly, the detachable connection method between the upper connecting frame 70 and the sliding bracket 51 can refer to the detachable connection method between the upper connecting frame 70 and the upper positioning cylinder 52, and will not be repeated here.

[0060] Furthermore, the lower connecting frame 80 and the lower positioning cylinder 42 can be connected by bolts, allowing for a detachable connection. Alternatively, the lower connecting frame 80 and the lower positioning cylinder 42 can also be detachably connected in other ways. For example, the lower connecting frame 80 can be connected with a buckle, and the lower positioning cylinder 42 can be provided with a matching slot or engaging component. The lower connecting frame 80 and the lower positioning cylinder 42 can be detachably connected by engaging the buckle with the slot or engaging the engaging component. The specific connection method for the detachable connection of the lower connecting frame 80 and the lower positioning cylinder 42 is not limited in this embodiment. Similarly, the detachable connection method between the lower connecting frame 80 and the fixed bracket 41 can refer to the detachable connection method between the lower connecting frame 80 and the lower positioning cylinder 42, and will not be elaborated further here.

[0061] In addition, in this embodiment, the upper connecting frame 70 may include two upper connecting rods. The first end of one upper connecting rod is connected to the first end of the other upper connecting rod, and the axes of the two upper connecting rods are at an included angle. The second ends of the two upper connecting rods are respectively connected to buckles. The sliding bracket 51 is provided with a slot or a snap-fit ​​component. The buckles at the second ends of the two upper connecting rods engage with the slot or the snap-fit ​​component, so that the second ends of the two upper connecting rods are detachably connected to the sliding bracket 51. A buckle is provided at the connection point of the first ends of the two upper connecting rods. The upper positioning cylinder 52 is provided with a slot or snap-fit ​​component that matches the buckle. The buckle at the connection point of the first ends of the two upper connecting rods engages with the slot or the snap-fit ​​component, so that the first ends of the two upper connecting rods are detachably connected to the upper positioning cylinder 52. Of course, the upper connecting frame 70 may also include at least three upper connecting rods. When the connecting frame includes at least three upper connecting rods, the specific connection method can refer to the connection method of the upper connecting frame 70 including two upper connecting rods, and is not limited here. In addition, the number of upper connecting frames 70 can be set according to actual needs.

[0062] Additionally, the lower connecting frame 80 may include two lower connecting rods, with the first end of one lower connecting rod connected to the first end of the other lower connecting rod, and the axes of the two lower connecting rods forming an angle. The second ends of the two lower connecting rods are respectively connected to buckles. The sliding bracket 51 is provided with a slot or a snap-fit ​​component. The buckles at the second ends of the two lower connecting rods engage with the slot or the snap-fit ​​component, allowing the second ends of the two lower connecting rods to be detachably connected to the sliding bracket 51. A buckle is provided at the connection point of the first ends of the two lower connecting rods, and the upper positioning cylinder 52 is provided with a slot or snap-fit ​​component that matches the buckle. The buckles at the connection point of the first ends of the two lower connecting rods engage with the slot or the snap-fit ​​component, allowing the first ends of the two lower connecting rods to be detachably connected to the upper positioning cylinder 52. Of course, the lower connecting frame 80 may also include at least three lower connecting rods. When the connecting frame includes at least three lower connecting rods, the specific connection method can refer to the connection method of the lower connecting frame 80 including two lower connecting rods, and is not limited here. In addition, the number of lower connecting frames 80 can be set according to actual needs.

[0063] In addition, in some embodiments, there are multiple upper connecting frames 70, and the multiple upper connecting frames 70 have different sizes. One upper connecting frame 70 is detachably connected to the sliding bracket 51. There are multiple lower connecting frames 80, and the multiple lower connecting frames 80 have different sizes. One lower connecting frame 80 is detachably connected to the fixed bracket 41.

[0064] Since there are multiple upper connecting frames 70, and each upper connecting frame 70 has a different size, and each upper connecting frame 70 is detachably connected to the sliding bracket 51, the upper connecting frame 70 can be replaced as needed. Because different upper connecting frames 70 have different sizes, replacing an upper connecting frame 70 is equivalent to adjusting the distance between the upper positioning cylinder 52 and the sliding bracket 51. This change in distance allows for adaptation to different installation requirements, thus improving the adaptability of the piling positioning guide bracket. In other words, by setting multiple upper connecting frames 70, the distance between the upper positioning cylinder 52 and the sliding bracket 51 can be adjusted by replacing the upper connecting frame 70, making the application range of the piling positioning guide bracket wider. Similarly, there are multiple lower connecting frames 80, each with different dimensions. Each lower connecting frame 80 is detachably connected to the sliding bracket 51. Therefore, the lower connecting frames 80 can be replaced as needed. Since the different lower connecting frames 80 have different dimensions, replacing one is equivalent to adjusting the distance between the lower positioning cylinder 42 and the sliding bracket 51. This change in distance allows for adaptation to different installation requirements, improving the adaptability of the piling positioning guide bracket. In other words, by setting multiple lower connecting frames 80, the distance between the lower positioning cylinder 42 and the sliding bracket 51 can be adjusted by replacing the lower connecting frames 80, thus broadening the application range of the piling positioning guide bracket.

[0065] It should be noted that the upper connecting frame 70 has the same dimensions as the lower connecting frame 80. That is, different upper connecting frames 70 correspond to different lower connecting frames 80. Thus, when replacing the upper connecting frame 70, the lower connecting frame 80 is replaced simultaneously, ensuring that the upper positioning cylinder 52 and the lower positioning cylinder 42 are always axially opposite each other in the positioning frame 10, and that the axis of the upper positioning cylinder 52 is collinear with the axis of the lower positioning cylinder 42.

[0066] For example, there are three upper connecting frames 70, namely upper connecting frame A, upper connecting frame B, and upper connecting frame C, and three lower connecting frames 80, namely lower connecting frame A, lower connecting frame B, and lower connecting frame C. The dimensions of upper connecting frame A and lower connecting frame B are the same, the dimensions of upper connecting frame B and lower connecting frame C are the same, and the dimensions of upper connecting frame C and lower connecting frame C are the same. Therefore, if upper connecting frame A is connected to upper positioning cylinder 52 and sliding bracket 51 respectively, and lower connecting frame A is connected to lower positioning cylinder 42 and fixed bracket 41 respectively, when it is necessary to replace upper connecting frame A with upper connecting frame B, it is necessary to simultaneously replace lower connecting frame A with lower connecting frame B to ensure that the upper positioning cylinder 52 and lower positioning cylinder 42 are in relative positions.

[0067] In addition, in the embodiments of this application, when the upper connecting frame 70 includes two or at least three upper connecting rods, the lengths of the upper connecting rods included in different upper connecting frames 70 are different, thereby making the sizes of different upper connecting frames 70 different; when the lower connecting frame 80 includes two or at least three lower connecting rods, the lengths of the lower connecting rods included in different lower connecting frames 80 are different, thereby making the sizes of different lower connecting frames 80 different.

[0068] Additionally, in some embodiments, such as Figure 1 or Figure 2 As shown, the drive component 60 is a motor, and the motor is connected to a traction rope 61. The traction rope 61 is connected to the sliding bracket 51. The drive component 60 drives the traction rope 61 to move relative to the positioning frame 10, so that the traction rope 61 drives the sliding bracket 51 to slide relative to the positioning frame 10.

[0069] Since the drive assembly 60 is connected to the traction rope 61, and the traction rope 61 is connected to the sliding bracket 51, once the drive assembly 60 is running, it can apply force to the traction rope 61, causing the traction rope 61 to move relative to the positioning frame 10. Once the traction rope 61 moves, it can drive the sliding bracket 51 to slide relative to the positioning frame 10, causing the sliding bracket 51 to drive the upper positioning cylinder 52 to move relative to the positioning frame 10. Furthermore, by setting the traction rope 61, it is ensured that the drive assembly 60 can drive the sliding bracket 51 to move relative to the positioning frame 10, provided that there is a certain distance between the drive assembly 60 and the sliding assembly.

[0070] It should be noted that the traction rope 61 can be a steel wire rope to ensure that the traction rope 61 has greater strength and greater traction force. In addition, in this embodiment of the application, the traction rope 61 can also be formed of an iron chain, that is, the iron chain is equivalent to the traction rope 61, so that the sliding component can move relative to the positioning frame 10.

[0071] Additionally, in some embodiments, such as Figure 3 As shown, the output end of the motor is connected to a lead screw 62, and the extension direction of the lead screw 62 is parallel to the axis of the positioning frame 10. A slider 63 is provided on the lead screw 62, and the traction rope 61 is connected to the slider 63.

[0072] With this setup, once the motor starts, the output of the drive assembly 60 can drive the lead screw 62 to rotate. The slider 63 on the lead screw 62 can then move along the extension direction of the lead screw 62. Essentially, using the principle of the lead screw 62 and nut, the rotational motion of the lead screw 62 is converted into the linear motion of the slider 63. Since the extension direction of the lead screw 62 is parallel to the axis of the positioning frame 10, when the slider 63 moves relative to the lead screw 62, it can move along the axis of the positioning frame 10. Furthermore, the traction rope 61 is connected to the slider 63. Therefore, after the slider 63 moves, it can drive the traction rope 61 to move along the axis of the positioning frame 10, causing the traction rope 61 to move the sliding bracket 51 along the axis of the positioning frame 10. In other words, by setting up the lead screw 62, the drive assembly 60 can easily operate, allowing the sliding bracket 51 to move relative to the positioning frame 10.

[0073] It should be noted that when the motor output rotates and the lead screw 62 rotates in the first rotation direction, the slider 63 moves away from the drive assembly 60, which is equivalent to causing the sliding bracket 51 to descend relative to the positioning frame 10. When the lead screw 62 rotates in the second rotation direction, the slider 63 moves closer to the drive assembly 60, which is equivalent to causing the sliding bracket 51 to rise relative to the positioning frame 10. The first and second rotation directions are opposite; the first rotation direction can be clockwise, and the second rotation direction can be counterclockwise.

[0074] Additionally, in some embodiments, such as Figure 4 As shown, the output end of the motor is connected to a rope winder 64, and part of the traction rope 61 is wound around the rope winder 64. The axis of the rope winder 64 intersects the axis of the positioning frame 10 and has an angle.

[0075] With this configuration, once the motor is running, the output of the drive assembly 60 can drive the rope winder 64 to rotate, and part of the traction rope 61 is wound around the rope winder 64. Thus, as the rope winder 64 rotates, the traction rope 61 continues to wind around it, effectively applying force to the sliding bracket 51, causing the sliding bracket 51 to move upward relative to the positioning frame 10. Alternatively, as the rope winder 64 rotates, the traction rope 61 can separate from it, effectively causing the sliding bracket 51 to move downward relative to the positioning frame 10. In short, by configuring the rope winder 64, the movement of the sliding bracket 51 relative to the positioning frame 10 can be facilitated during the operation of the drive assembly 60.

[0076] It should be noted that the angle between the axis of the rope winder 64 and the axis of the positioning frame 10 can be 90 degrees, that is, the axis of the rope winder 64 is perpendicular to the axis of the positioning frame 10. Of course, the angle between the axis of the rope winder 64 and the axis of the positioning frame 10 can also be other angles, for example, 85 degrees, or even 93 degrees. This embodiment of the application does not limit this to any particular angle.

[0077] In addition, in this embodiment, the motor can also be connected to the sliding bracket 51 via a traction rod. In this case, the drive assembly 60 drives the traction rod to move relative to the positioning frame 10, thereby causing the traction rod to drive the sliding bracket 51 to slide relative to the positioning frame 10. When the drive assembly 60 is connected to the sliding bracket 51 via the traction rod, the traction rod can be connected to a slider 63 on a lead screw 62 connected to the output end of the drive assembly 60. This causes the slider 63 to move relative to the lead screw 62, thereby driving the traction rod to move relative to the positioning frame 10.

[0078] In some embodiments, the drive assembly 60 is an electric hoist connected to the sliding bracket 51 to move the sliding bracket 51 relative to the positioning frame 10. This configuration allows for direct access to the electric hoist, which has a simpler structure, avoiding the need for additional devices and making the installation of the piling positioning guide frame more convenient.

[0079] Additionally, in some embodiments, such as Figure 1 or Figure 2 As shown, the upper positioning cylinder 52 is connected to an upper flared structure 521 at its upper end, and the lower end of the upper flared structure 521 is consistent with the upper positioning cylinder 52; the lower positioning cylinder 42 is connected to a lower flared structure 421, and the lower end of the lower flared structure 421 is consistent with the lower positioning cylinder 42. The openings of the upper flared structure 521 and the lower flared structure 421 are both upward and coaxial.

[0080] Because the upper positioning cylinder 52 is connected to the upper flared structure 521, and the lower end of the upper flared structure 521 is aligned with the upper positioning cylinder 52, during the piling process, once the steel pile is moved to the upper flared structure 521 by the hoisting device, the larger opening of the upper flared structure 521 facilitates the steel pile's entry into the upper flared structure 521. The steel pile can then proceed along the upper flared structure 521 into the upper positioning cylinder 52. In other words, by setting up the upper flared structure 521, it is easier for the steel pile to enter the upper positioning cylinder 52 during piling, thus facilitating the steel pile's penetration through the upper positioning cylinder 52. Similarly, since the lower positioning cylinder 42 is connected to the lower flared structure 421, and the lower end of the lower flared structure 421 is aligned with the lower positioning cylinder 42, during the piling process, once the steel pile passes through the upper positioning cylinder 52 and moves to the lower flared structure 421, the larger opening of the lower flared structure 421 facilitates the steel pile's entry into the lower flared structure 421. The steel pile can then proceed along the lower flared structure 421 into the lower positioning cylinder 42. In other words, by setting the lower flared structure 421, it is easier for the steel pile to enter the lower positioning cylinder 42 during piling, thus facilitating the piling process.

[0081] It should be noted that the upper flared structure 521 can be welded to one end of the upper positioning cylinder 52; of course, the upper flared structure 521 and the upper positioning cylinder 52 can also be an integral structure. This embodiment of the application does not limit this aspect. Additionally, the lower flared structure 421 can be welded to one end of the lower positioning cylinder 42; of course, the lower flared structure 421 and the lower positioning cylinder 42 can also be an integral structure. This embodiment of the application does not limit this aspect.

[0082] Additionally, in some embodiments, such as Figure 1 or Figure 2 As shown, the positioning frame 10 may include multiple columns 11 and multiple crossbeams 12; the lower end of the column 11 is connected to the fixed foundation 20, the multiple columns 11 are spaced apart, and the line connecting the projections of the multiple columns 11 along the axis of the positioning frame 10 forms a closed shape. Along the circumferential direction of the closed shape, at least two adjacent columns 11 are provided with crossbeams 12, and the crossbeams 12 are respectively connected to two columns 11. The axis of the crossbeams 12 is perpendicular to the axis of the columns 11.

[0083] Since multiple columns 11 are distributed at intervals, a crossbeam 12 is provided between at least two adjacent columns 11 along the circumferential direction of the closed shape, and the crossbeam 12 connects the two columns 11 respectively. Therefore, the crossbeam 12 is equivalent to connecting the two columns 11, and the crossbeam 12 can play a reinforcing role, thereby increasing the strength of the positioning frame 10 and making the structure of the positioning frame 10 more stable, that is, ensuring that the structural stability of the positioning frame 10 is high.

[0084] It should be noted that, in this embodiment, a crossbeam 12 can be provided between any two adjacent columns 11 along the circumferential direction of the closed shape, and the number of crossbeams 12 between two adjacent columns 11 can be set according to actual needs. For example, the number of crossbeams 12 between two adjacent columns 11 is 5, and the 5 crossbeams 12 are distributed at intervals along the axial direction of the columns 11. As another example, the number of crossbeams 12 between two adjacent columns 11 is 3, and the 3 crossbeams 12 are distributed at intervals along the axial direction of the columns 11. This embodiment does not limit the specific number of crossbeams 12 in this application.

[0085] Furthermore, in this embodiment, the number of columns 11 can be set according to actual needs. In some embodiments, the number of columns 11 is four. In this case, the line connecting the projections of the four columns 11 along the axis of the positioning frame 10 forms a closed shape, which can be a square. This arrangement makes the structure of the positioning frame 10 simpler. In some embodiments, the number of columns 11 is three. In this case, the line connecting the projections of the three columns 11 along the axis of the positioning frame 10 forms a closed shape, which can be an equilateral triangle. This arrangement makes the structure of the positioning frame 10 simpler.

[0086] Of course, the number of columns 11 can also be other numbers, for example, the number of columns 11 can be 6. The specific number of columns 11 is not limited in this embodiment.

[0087] Additionally, in some embodiments, such as Figure 1 or Figure 2 As shown, a hoisting assembly 13 is connected above the column 11. The hoisting assembly 13 is used to connect the hoisting device to facilitate the transportation and movement of the entire positioning guide frame.

[0088] Since at least two of the columns 11 are connected to the other end of the hoisting assembly 13, when it is necessary to move the piling positioning guide frame, it can be connected to the hoisting assembly 13 by the hoisting device, so that the hoisting device can lift the piling positioning guide frame with the support, making it easy to move the piling positioning guide frame. That is, by connecting the hoisting assembly 13 to the other end of at least two of the columns 11, it is easy to move the piling positioning guide frame.

[0089] It should be noted that the lifting assembly 13 can be a lifting ring, that is, the lifting assembly 13 has a ring-shaped structure. Of course, the lifting assembly 13 can also be a hook, that is, the lifting assembly 13 has a hook-shaped structure. The specific type of the lifting assembly 13 is not limited in this embodiment.

[0090] In addition, in this embodiment, a hoisting assembly 13 can be connected to the other end of each column 11, so that when the piling positioning guide frame needs to be moved, the hoisting assembly 13 on each column 11 can be connected to the hoisting device, so that the piling positioning guide frame is subjected to more uniform force and ensures that the piling positioning guide frame is not easily tilted when it is hoisted.

[0091] Additionally, in some embodiments, such as Figure 1 or Figure 2 As shown, the positioning frame 10 may also include multiple reinforcing beams 14; along the circumferential direction of the closed shape, at least one reinforcing beam 14 is provided between at least two adjacent columns 11, and the reinforcing beam 14 connects the two columns 11 respectively, and the axis of the reinforcing beam 14 intersects the axis of the column 11.

[0092] Since at least one reinforcing beam 14 is provided between at least two adjacent columns 11, and the reinforcing beam 14 connects the two columns 11 respectively, and the axis of the reinforcing beam 14 intersects the axis of the column 11, it is equivalent to the reinforcing beam 14 being inclined relative to the column 11. Thus, the reinforcing beam 14 can effectively strengthen the structure of the pile driving positioning guide frame, further ensuring the high structural stability of the pile driving positioning guide frame.

[0093] It should be noted that, in this embodiment, reinforcing beams 14 can be provided between any two adjacent columns 11 along the circumferential direction of the closed shape. The number of reinforcing beams 14 between two adjacent columns 11 can be set according to actual needs. For example, there can be five reinforcing beams 14 between two adjacent columns 11, spaced apart along the axial direction of the columns 11, or the five reinforcing beams 14 can intersect. As another example, there can be three reinforcing beams 14 between two adjacent columns 11, spaced apart along the axial direction of the columns 11, or the three reinforcing beams 14 can intersect. This embodiment does not limit the specific number of reinforcing beams 14 in this regard.

[0094] Additionally, in some embodiments, such as Figure 2 As shown, the fixed foundation 20 may include a single monotube multi-compartment cylindrical foundation 21, that is, the fixed foundation 20 is composed of monotube multi-compartment cylindrical foundations 21; the positioning frame 10 is connected to the monotube multi-compartment cylindrical foundation 21.

[0095] Since the positioning frame 10 is connected to the single-tube multi-compartment cylindrical foundation 21, it is equivalent to positioning the positioning frame 10 through a single single-tube multi-compartment cylindrical foundation 21. This saves on the number of fixing cylinders and allows for faster installation of the single-tube multi-compartment cylindrical foundation 21 in a suitable position, improving the installation efficiency of the piling positioning guide frame. In other words, by setting up the single-tube multi-compartment cylindrical foundation 21, the installation efficiency of the piling positioning guide frame can be effectively improved.

[0096] It should be noted that the single-tube multi-compartment cylindrical foundation 21 is provided with a partition to divide the interior of the single-tube multi-compartment cylindrical foundation 21 into multiple compartments. The partition can divide the single-tube multi-compartment cylindrical foundation into 6 compartments, or it can be divided into other numbers of compartments. This embodiment of the application does not limit the specific division in this regard.

[0097] Additionally, in some embodiments, such as Figure 1 As shown, the fixed foundation 20 can be composed of multiple single-cylinder, single-compartment cylindrical foundations 22, which are simultaneously connected to one end of the positioning frame 10. The multiple single-cylinder, single-compartment cylindrical foundations are respectively connected to the columns 11 to fix the positioning frame 10.

[0098] Since multiple single-tube, single-compartment cylindrical foundations 22 are simultaneously connected to one end of the positioning frame 10, and these foundations are spaced apart, the positioning frame 10 is effectively fixed by these foundations. This multiple fixed cylinders ensure a more balanced force distribution on the positioning frame 10, thus guaranteeing its stability. In other words, by setting multiple single-tube, single-compartment cylindrical foundations 22, the stability of the positioning frame 10 can be improved.

[0099] It should be noted that, in this embodiment, a water pump needs to be placed on the support platform 30. The water pump can draw water into the single-cylinder multi-compartment cylindrical foundation 21 for installation, thereby fixing the positioning frame 10 to the single-cylinder multi-compartment cylindrical foundation 21. Of course, when the fixed foundation 20 includes multiple single-cylinder single-compartment cylindrical foundations 22, water can also be drawn into the single-cylinder single-compartment cylindrical foundations 22 for installation, thereby fixing the positioning frame 10 to the single-cylinder single-compartment cylindrical foundation 22. The number of water pumps can be equal to the number of single-cylinder single-compartment cylindrical foundations 22, that is, one water pump corresponds to one single-cylinder single-compartment cylindrical foundation 22. This allows multiple water pumps to simultaneously draw water from multiple single-cylinder single-compartment cylindrical foundations 22, ensuring that multiple single-cylinder single-compartment cylindrical foundations 22 can be quickly installed, thereby fixing the positioning frame 10.

[0100] In addition, in this embodiment, when the positioning frame 10 includes multiple columns 11, one end of each column 11 can be simultaneously connected to a single-tube multi-compartment cylindrical foundation 21, which is equivalent to fixing multiple columns 11 through a single tube; of course, one end of each column 11 can also be connected to multiple single-tube single-compartment cylindrical foundations 22 respectively, which is equivalent to one end of one column 11 being connected to one single-tube single-compartment cylindrical foundation 22, which is equivalent to fixing multiple columns 11 through multiple tubes.

[0101] In addition, in the implementation of this application, the level of the positioning frame 10 can be adjusted by pumping water into multiple single-cylinder single-chamber cylindrical foundations 22 to ensure that the positioning frame 10 is level and to avoid tilting of the positioning frame 10.

[0102] Additionally, in some embodiments, such as Figure 1 or Figure 2 As shown, the positioning frame 10 is provided with a sliding groove, and the sliding bracket 51 is connected to a pulley 511. The pulley 511 is embedded in the sliding groove, so that the sliding bracket 51 and the positioning frame 10 are slidably connected. With this arrangement, once the sliding bracket 51 is subjected to force, it can apply force to the pulley 511, so that the pulley 511 can slide in the sliding groove, causing the position of the sliding bracket 51 relative to the positioning frame 10 to change. That is, by setting the sliding bracket and the pulley 511, the sliding bracket 51 can be easily slid relative to the positioning frame 10.

[0103] It should be noted that the extension of the slide groove is in the same direction as the axis of the positioning frame 10. When the positioning frame 10 includes multiple columns 11, a slide groove can be provided on the outer wall of the column 11, and the extension direction of the slide groove is in the same direction as the axis of the column 11.

[0104] Of course, in this embodiment, a slide rail can also be provided on the positioning frame 10, and the sliding bracket 51 is connected to the pulley 511, with the pulley 511 embedded in the slide rail, so that the sliding bracket 51 and the positioning frame 10 are slidably connected. Alternatively, a sliding groove can be provided on the positioning frame 10, and the sliding bracket 51 is connected to the slider 63, with the slider 63 embedded in the sliding groove, so that the sliding bracket 51 and the positioning frame 10 are slidably connected. The specific connection method of the sliding bracket 51 and the positioning frame 10 is not limited in this embodiment.

[0105] In this embodiment, since the fixed foundation 20 is connected to one end of the positioning frame 10, when using the piling positioning guide frame, the fixed foundation 20 can be placed on the seabed surface below the sea surface to fix the positioning frame 10, ensuring its stability. Additionally, the support platform 30 and the fixed guide platform 40 are both fixedly connected to the positioning frame 10, and the sliding guide platform 50 is slidably connected to the positioning frame 10. The support platform 30 and the fixed guide platform 40 are spaced apart along the axial direction of the positioning frame 10, and the sliding guide platform 50 is located between the support platform 30 and the fixed guide platform 40. Therefore, force can be applied to the sliding guide platform 50, allowing it to slide relative to the axial direction of the positioning frame 10, thus changing its position relative to the positioning frame 10. In addition, a drive assembly 60 is provided on the support platform 30. The sliding guide platform 50 includes a connected sliding bracket 51 and an upper positioning cylinder 52. The sliding bracket 51 is slidably connected to the positioning frame 10 and is connected to the drive assembly 60. Therefore, the drive assembly 60 can drive the sliding bracket 51 to move, so that the sliding bracket 51 drives the upper positioning cylinder 52 to move relative to the positioning frame 10. That is, the drive assembly 60 applies force to the sliding bracket 51, so that the sliding bracket 51 moves relative to the positioning frame 10. In this way, the sliding bracket 51 can drive the upper positioning cylinder 52 to move along the axial direction of the positioning frame 10. In addition, the fixed positioning assembly includes a connected fixed bracket 41 and a lower positioning cylinder 42. The fixed bracket 41 is fixedly connected to the positioning frame 10. The upper positioning cylinder 52 is coaxial with the lower positioning cylinder 42 and parallel to the axial direction of the positioning frame 10. Therefore, when using the pile driving positioning guide frame, the fixed guide platform 40 can be positioned below the sea level, and the sliding guide platform 50 can be positioned above the sea level. That is, the fixed guide platform 40 is below the sea level, and the sliding guide platform 50 is above the sea level, thus enabling precise positioning of the steel pile. The sliding bracket 51 is moved relative to the positioning frame 10 to a suitable position by the drive component 60. Then, the steel pile is first inserted into the upper positioning cylinder 52. The upper positioning cylinder 52 can then position the steel pile. Even if the steel pile penetrates below the sea surface, part of the steel pile is still located in the upper positioning cylinder 52. Thus, the upper positioning cylinder 52 can ensure that the steel pile is stably positioned by the upper positioning cylinder 52 when it is subjected to ocean currents or waves. The upper positioning cylinder 52 is opposite to the lower positioning cylinder 42, so the steel pile can enter the lower positioning cylinder 42.

[0106] In other words, by setting up a sliding guide platform 50 and connecting the drive component 60 to the sliding guide platform 50, during piling, the steel pile can be hoisted to the piling positioning guide frame by a hoisting device, and the sliding component is moved by the drive component 60, so that the upper positioning cylinder 52 of the sliding component moves to a suitable position. Then the steel pile is inserted into the upper positioning cylinder 52. The upper positioning cylinder 52 is above the sea surface, so the upper positioning cylinder 52 will not be affected by the sea current or waves, and the steel pile is above the sea surface and will not be affected by the sea current or waves, which facilitates the steel pile to be inserted into the upper positioning cylinder 52. After the steel pile penetrates below the sea surface, the steel pile is limited by the upper positioning cylinder 52. The upper positioning cylinder 52 and the lower positioning cylinder 42 are coaxial, so the steel pile is effectively limited, which facilitates the steel pile to penetrate into the lower positioning cylinder 42. The upper positioning cylinder 52 and the lower positioning cylinder 42 simultaneously limit the steel pile, which facilitates subsequent piling and can effectively improve the piling efficiency.

[0107] This application provides a construction method applicable to the piling positioning guide frame in any of the above embodiments, such as... Figure 5 As shown, the construction method includes:

[0108] Step 501: Transport the piling positioning guide frame to the construction sea area, and adjust the position of the sliding guide platform relative to the positioning frame according to the water depth so that the sliding guide platform is above the sea level.

[0109] In this way, the drive component can be controlled to make the sliding guide platform slide relative to the positioning frame, which is equivalent to making the sliding support slide to the set position. The sliding support is located above the sea surface, so that the upper positioning cylinder is located above the sea surface.

[0110] It should be noted that a control component can be installed on the support platform. The control component is electrically connected to the drive component, and the drive component is controlled to operate through the control component.

[0111] In addition, when transporting the piling positioning guide frame, the piling positioning guide frame can be placed horizontally, or it can be placed vertically.

[0112] Step 502: Place the piling positioning guide frame on the seabed surface by hoisting, and install the fixed foundation in place by suction installation.

[0113] The hoisting components on the positioning frame can be hoisted using a hoisting device, which will lift the piling positioning guide frame. The piling positioning guide frame will then be placed in the seawater, with the fixed foundation positioned on the seabed surface. Finally, the fixed foundation will be installed using a suction installation method, ensuring that the fixed foundation is in place.

[0114] Step 503: Insert one or more steel piles to be installed into the seabed through the upper positioning cylinder and the lower positioning cylinder in sequence. After the steel piles have sank to the bottom by their own weight, install the pile hammer and pile driver, and begin the pile driving construction.

[0115] In some implementations, step 503 can be implemented as follows: one or more steel piles to be installed are sequentially driven into the seabed through the upper positioning cylinder and the lower positioning cylinder; after the steel piles have sunk under their own weight, the sliding guide platform is adjusted by the drive component to move it downwards until it is away from the end of the steel pile above sea level; then the pile hammer and pile driver are installed, and pile driving begins. That is, during construction, the height of the sliding guide platform, i.e., the height of the upper positioning cylinder, is adjusted according to the depth of the steel piles in the mud, causing the upper positioning cylinder to move downwards, avoiding any impact on pile driving and facilitating precise construction.

[0116] In addition, in this embodiment of the application, after all the steel piles are constructed, water is injected into the fixed foundation to cause vertical displacement, and at the same time the pile driving positioning guide frame is hoisted and retrieved. The entire installation and retrieval process of the pile driving positioning guide frame is completed through the above construction.
