Description

Technical Field

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

[0002] With the implementation of the national dual-carbon strategy, 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, 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.

[0016] Optionally, both the upper telescopic member and the lower telescopic member are hydraulic telescopic members.

[0017] Optionally, the piling positioning guide frame further includes a support platform, which is connected to the positioning frame and spaced apart from the upper support.

The driving component is configured to drive the upper support to slide relative to the positioning frame.

[0018] Optionally, the drive assembly is connected to a traction rope, which is connected to the upper support. The drive assembly drives the traction rope to move relative to the positioning frame, so that the traction rope causes the upper support to slide relative to the positioning frame.

[0023] 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.

[0024] 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, wherein the upper support is slidably connected to the positioning frame, and the construction method includes:

[0025] The piling positioning guide frame is transported to the construction sea area, and the position of the upper guide platform relative to the positioning frame is adjusted according to the water depth so that the upper guide platform is above the sea level;

[0026] The piling positioning guide frame is placed on the seabed surface by hoisting, and the fixed foundation is installed in place by suction installation.

[0027] 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.

[0028] 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:

[0029] 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;

[0030] After the steel pile has sank to its final depth under its own weight, the upper guide platform is adjusted by the drive assembly to move it downwards until it moves away from the end of the steel pile that is above sea level.

[0031] The installation of the pile hammer and pile driver began, and pile driving construction commenced.

[0032] 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 and ensure its stability. Furthermore, both the upper and lower guide platforms are connected to the positioning frame and are spaced apart along the axial direction of the positioning frame. Therefore, when using the piling positioning guide frame, the lower guide platform can be positioned below the sea level, and the upper guide platform above the sea level; that is, the lower guide platform is below the sea level, and the upper guide platform is above the sea level. In addition, the upper guide platform includes an upper support and an upper positioning cylinder, and the lower guide platform includes a lower support and a lower positioning cylinder. The upper support is connected to the positioning frame, and the upper positioning cylinder is telescopically connected to the upper support. The lower support is connected to the positioning frame, and the lower positioning cylinder is telescopically connected to the lower support. Thus, when positioning the steel pile, the position of the upper positioning cylinder relative to the upper support and the position of the lower guide platform relative to the lower support can be adjusted to ensure that the upper and lower positioning cylinders are in the appropriate positions. Then, the steel pile is first inserted into the upper positioning cylinder, which can then position the steel pile. Even if the steel pile extends below the sea surface, 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 affected by ocean currents or waves. With the upper and lower positioning cylinders facing each other, the steel pile can then enter the lower positioning cylinder.

[0033] In other words, by setting up an upper guide platform and a lower guide platform, with the upper positioning cylinder of the upper guide platform being telescopically connected to the upper support, and the lower positioning cylinder of the lower guide platform being telescopically connected to the lower support, the steel pile can be hoisted to the piling positioning guide frame by a hoisting device during piling. By adjusting the positions of the upper and lower positioning cylinders, the upper positioning cylinder is moved to a suitable position, and then the steel pile is inserted through the upper positioning cylinder. The upper positioning cylinder is located above the sea surface, so it will not be affected by ocean currents or waves, and the steel pile will also not be affected by ocean currents or waves, making it easy for the steel pile to be inserted through the upper positioning cylinder. After the steel pile extends below the sea surface, it is limited by the upper positioning cylinder. The upper and lower positioning cylinders are positioned opposite each other, so the steel pile is effectively limited, making it easy for the steel pile to extend into the lower positioning cylinder. The upper and lower positioning cylinders simultaneously limit the steel pile, facilitating subsequent piling and thus effectively improving piling efficiency. Attached Figure Description

Furthermore, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0047] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0048] 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.

[0049] like Figures 1 to 8 As shown, the piling positioning guide frame includes: a positioning frame 10, a fixed foundation 20, an upper guide platform 30, and a lower guide platform 40.

[0050] A fixed base 20 is connected to one end of the positioning frame 10. The upper guide platform 30 and the lower guide platform 40 are both connected to the positioning frame 10. The upper guide platform 30 and the lower guide platform 40 are distributed at intervals along the axial direction of the positioning frame 10. The upper guide platform 30 includes an upper support 31 and an upper positioning cylinder 32. The lower guide platform 40 includes a lower support 41 and a lower positioning cylinder 42. The upper support 31 is connected to the positioning frame 10. The upper positioning cylinder 32 is telescopically connected to the upper support 31. The lower support 41 is connected to the positioning frame 10. The lower positioning cylinder 42 is telescopically connected to the lower support 41. The upper positioning cylinder 32 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 32 is used to be located above the sea level.

[0051] 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 level to fix the positioning frame 10, ensuring its stability. Furthermore, both the upper guide platform 30 and the lower guide platform 40 are connected to the positioning frame 10, and are spaced apart along the axial direction of the positioning frame 10. Therefore, when using the piling positioning guide frame, the lower guide platform 40 can be positioned below the sea level, and the upper guide platform 30 above the sea level; that is, the lower guide platform 40 is below the sea level, and the upper guide platform 30 is above the sea level. In addition, the upper guide platform 30 includes an upper support 31 and an upper positioning cylinder 32, and the lower guide platform 40 includes a lower support 41 and a lower positioning cylinder 42. The upper support 31 is connected to the positioning frame 10, and the upper positioning cylinder 32 is telescopically connected to the upper support 31. The lower support 41 is connected to the positioning frame 10, and the lower positioning cylinder 42 is telescopically connected to the lower support 41. Therefore, when positioning the steel pile, the position of the upper positioning cylinder 32 relative to the upper support 31 can be adjusted, and the position of the lower guide platform 40 relative to the lower support 31 can also be adjusted. The position of the frame 41 ensures that the upper positioning cylinder 32 and the lower positioning cylinder 42 are in suitable positions. Then, the steel pile is first inserted into the upper positioning cylinder 32, which can position the steel pile. Even if the steel pile extends below the sea surface, part of the steel pile is still located in the upper positioning cylinder 32. Thus, the upper positioning cylinder 32 can ensure that the steel pile is stably positioned by the upper positioning cylinder 32 when it is affected by ocean currents or waves. Since the upper positioning cylinder 32 is opposite to the lower positioning cylinder 42, the steel pile can enter the lower positioning cylinder 42.

[0052] That is, by setting up an upper guide platform 30 and a lower guide platform 40, with the upper positioning cylinder 32 of the upper guide platform 30 being telescopically connected to the upper support 31, and the lower positioning cylinder 42 of the lower guide platform 40 being telescopically connected to the lower support 41, the steel pile can be hoisted to the piling positioning guide frame by a hoisting device during piling. By adjusting the positions of the upper positioning cylinder 32 and the lower positioning cylinder 42, the upper positioning cylinder 32 is moved to a suitable position, and then the steel pile is inserted through the upper positioning cylinder 32. Located above the sea surface, the upper positioning cylinder 32 is not affected by ocean currents or waves, and the steel pile is also unaffected by ocean currents or waves above the sea surface. This facilitates the insertion of the steel pile through the upper positioning cylinder 32. After the steel pile extends below the sea surface, it is limited by the upper positioning cylinder 32. The upper positioning cylinder 32 and the lower positioning cylinder 42 are positioned opposite each other, thus the steel pile is effectively limited, facilitating its insertion into the lower positioning cylinder 42. The upper positioning cylinder 32 and the lower positioning cylinder 42 simultaneously limit the steel pile, facilitating subsequent pile driving and effectively improving pile driving efficiency.

[0053] 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.

[0054] Furthermore, in this embodiment, the number of upper positioning cylinders 32 can be set according to actual needs. For example, there can be four upper positioning cylinders 32, which are spaced apart along the circumferential direction of the upper support 31. Alternatively, there can be six upper positioning cylinders 32, which are spaced apart along the circumferential direction of the upper support 31. That is, when there are multiple upper positioning cylinders 32, they are spaced apart along the circumferential direction of the upper support 31. The specific number of upper positioning cylinders 32 is not limited in this embodiment.

[0055] 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 lower support 41. Alternatively, there can be six lower positioning cylinders 42, which are spaced apart along the circumferential direction of the lower support 41. In other words, when there are multiple lower positioning cylinders 42, they are spaced apart along the circumferential direction of the lower support 41. The specific number of lower positioning cylinders 42 is not limited in this embodiment.

[0056] In addition, in this embodiment, the number of upper positioning cylinders 32 is equal to the number of lower positioning cylinders 42, and one upper positioning cylinder 32 corresponds to one lower positioning cylinder 42.

[0057] Additionally, in some embodiments, such as Figure 1 or Figure 2 As shown, the piling positioning guide frame may further include an upper telescopic member 50 and a lower telescopic member 60; one end of the upper telescopic member 50 is connected to the upper support 31, and the other end of the upper telescopic member 50 is connected to the upper positioning cylinder 32. The upper telescopic member 50 is telescopic, so that the distance between the upper positioning cylinder 32 and the upper support 31 can be adjusted; one end of the lower telescopic member 60 is connected to the lower support 41, and the other end of the lower telescopic member 60 is connected to the lower positioning cylinder 42. The lower telescopic member 60 is telescopic, so that the distance between the lower positioning cylinder 42 and the lower support 41 can be adjusted.

[0058] Since one end of the upper telescopic member 50 is connected to the upper bracket 31 and the other end is connected to the upper positioning cylinder 32, the upper telescopic member 50 can be extended or shortened to adjust the distance between the upper positioning cylinder 32 and the upper bracket 31. Specifically, when the upper telescopic member 50 extends, the distance between the upper positioning cylinder 32 and the upper bracket 31 increases; when the upper telescopic member 50 shortens, the distance between the upper positioning cylinder 32 and the upper bracket 31 decreases. In other words, by providing the upper telescopic member 50, the distance between the upper positioning cylinder 32 and the upper bracket 31 can be easily adjusted. Similarly, since one end of the lower telescopic member 60 is connected to the lower support 41 and the other end is connected to the lower positioning cylinder 42, the lower telescopic member 60 can be extended or shortened to adjust the distance between the lower positioning cylinder 42 and the lower support 41. Specifically, when the lower telescopic member 60 extends, the distance between the lower positioning cylinder 42 and the lower support 41 increases; when the lower telescopic member 60 shortens, the distance between the lower positioning cylinder 42 and the lower support 41 decreases. In other words, by providing the lower telescopic member 60, the distance between the lower positioning cylinder 42 and the lower support 41 can be easily adjusted.

[0059] It should be noted that when adjusting the length of the upper telescopic component 50, once the length of the upper telescopic component 50 is adjusted to a suitable length, the length of the lower telescopic component 60 can be adjusted to ensure that the upper positioning cylinder 32 and the lower positioning cylinder 42 are positioned opposite each other along the axial direction of the positioning frame 10, and that the axis of the upper positioning cylinder 32 is collinear with the axis of the lower positioning cylinder 42. Alternatively, the lengths of the upper telescopic component 50 and the lower telescopic component 60 can be adjusted simultaneously to ensure that the axis of the upper positioning cylinder 32 is collinear with the axis of the lower positioning cylinder 42.

[0060] Additionally, in some embodiments, such as Figure 3 and Figure 4As shown, the upper telescopic component 50 may include an upper telescopic cylinder 51, an upper telescopic rod 52, and an upper fixing component 53. One end of the upper telescopic cylinder 51 is connected to the upper bracket 31. Multiple upper positioning holes 511 are spaced apart on the cylinder wall of the upper telescopic cylinder 51 along its axial direction. An upper positioning groove is provided on the outer wall of the upper telescopic rod 52. The upper telescopic rod 52 is embedded in the upper telescopic cylinder 51, and one end of the upper telescopic rod 52 is connected to the upper positioning cylinder 32. The upper fixing component 53 passes through the upper positioning holes 511 and is embedded in the upper positioning groove. The lower telescopic component 60 may include a lower telescopic cylinder 61, a lower telescopic rod 62, and a lower fixing component 63. One end of the lower telescopic cylinder 61 is connected to the lower bracket 41. Multiple lower positioning holes 611 are provided at intervals along the axial direction of the lower telescopic cylinder 61 on the cylinder wall. A lower positioning groove is provided on the outer wall of the lower telescopic rod 62. The lower telescopic rod 62 is embedded in the lower telescopic cylinder 61. One end of the lower telescopic rod 62 is connected to the lower positioning cylinder 42. The lower fixing component 63 passes through the lower positioning hole 611 and is embedded in the lower positioning groove.

[0061] Since one end of the upper telescopic cylinder 51 is connected to the upper support 31, and multiple upper positioning holes 511 are spaced apart on the cylinder wall of the upper telescopic cylinder 51 along the axial direction of the upper telescopic cylinder 51, and an upper positioning groove is provided on the outer wall of the upper telescopic rod 52, the upper telescopic rod 52 is embedded in the upper telescopic cylinder 51, and one end of the upper telescopic rod 52 is connected to the upper positioning cylinder 32, so when it is necessary to adjust the distance between the upper positioning cylinder 32 and the upper support 31, force can be applied to the upper telescopic rod 52 to make the length of the upper telescopic rod 52 extending into the upper telescopic cylinder 51 different, and then the upper positioning hole 511 is aligned with the upper positioning groove. The upper fixing member 53 is passed through the upper positioning hole 511 and embedded in the upper positioning groove to fix the position of the upper telescopic rod 52 and the upper positioning cylinder 32. Specifically, when it is necessary to increase the distance between the upper positioning cylinder 32 and the upper bracket 31, force is applied to the upper telescopic rod 52, causing the upper telescopic rod 52 to move away from the upper telescopic cylinder 51. This reduces the length of the upper telescopic rod 52 extending into the upper telescopic cylinder 51, moving the upper telescopic rod 52 to a suitable position where the upper positioning hole 511 aligns with the upper positioning groove. The upper fixing member 53 passes through the upper positioning hole 511 and is embedded in the upper positioning groove, limiting the upper telescopic rod 52 and ensuring that the upper telescopic rod 52 does not move relative to the upper telescopic cylinder 51. When it is necessary to reduce the distance between the upper positioning cylinder 32 and the upper support 31, force is applied to the upper telescopic rod 52, causing the upper telescopic rod 52 to move closer to the upper telescopic cylinder 51. This increases the length of the upper telescopic rod 52 extending into the upper telescopic cylinder 51, moving the upper telescopic rod 52 to a suitable position. The upper positioning hole 511 aligns with the upper positioning groove. The upper fixing member 53 passes through the upper positioning hole 511 and is embedded in the upper positioning groove, limiting the movement of the upper telescopic rod 52 and ensuring that it does not move relative to the upper telescopic cylinder 51. In other words, by setting the upper telescopic cylinder 51 and the upper telescopic rod 52, the distance between the upper positioning cylinder 32 and the upper support 31 can be easily adjusted.

[0062] Similarly, since one end of the lower telescopic cylinder 61 is connected to the lower support 41, and multiple lower positioning holes 611 are spaced apart on the cylinder wall of the lower telescopic cylinder 61 along the axial direction of the lower telescopic cylinder 61, and a lower positioning groove is provided on the outer wall of the lower telescopic rod 62, the lower telescopic rod 62 is embedded in the lower telescopic cylinder 61, and one end of the lower telescopic rod 62 is connected to the lower positioning cylinder 42, so when it is necessary to adjust the distance between the lower positioning cylinder 42 and the lower support 41, force can be applied to the lower telescopic rod 62 to make the length of the lower telescopic rod 62 extending into the lower telescopic cylinder 61 different, and then the lower positioning hole 611 is aligned with the lower positioning groove. The lower fixing member 63 is passed through the lower positioning hole 611 and embedded in the lower positioning groove to fix the position of the lower telescopic rod 62 and the lower positioning cylinder 42. Specifically, when it is necessary to increase the distance between the lower positioning cylinder 42 and the lower support 41, force is applied to the lower telescopic rod 62, causing the lower telescopic rod 62 to move away from the lower telescopic cylinder 61. This reduces the length of the lower telescopic rod 62 extending into the lower telescopic cylinder 61, moving the lower telescopic rod 62 to a suitable position where the lower positioning hole 611 aligns with the lower positioning groove. The lower fixing member 63 passes through the lower positioning hole 611 and is embedded in the lower positioning groove, limiting the lower telescopic rod 62 and ensuring that the lower telescopic rod 62 does not move relative to the lower telescopic cylinder 61. When it is necessary to reduce the distance between the lower positioning cylinder 42 and the lower support 41, force is applied to the lower telescopic rod 62, causing the lower telescopic rod 62 to move closer to the lower telescopic cylinder 61. This increases the length of the lower telescopic rod 62 extending into the lower telescopic cylinder 61, moving the lower telescopic rod 62 to a suitable position. The lower positioning hole 611 aligns with the lower positioning groove. The lower fixing member 63 passes through the lower positioning hole 611 and is embedded in the lower positioning groove, limiting the movement of the lower telescopic rod 62 and ensuring that it does not move relative to the lower telescopic cylinder 61. In other words, by setting the lower telescopic cylinder 61 and the lower telescopic rod 62, the distance between the lower positioning cylinder 42 and the lower support 41 can be easily adjusted.

[0063] It should be noted that both the upper fixing member 53 and the lower fixing member 63 can be pins. Of course, the upper fixing member 53 and the lower fixing member 63 can also be other types, such as screws. In this case, the walls of both the upper and lower positioning grooves can be threaded. When the upper fixing member 53 is inserted into the upper positioning groove, it can be threadedly connected to the upper positioning groove. When the lower fixing member 63 is inserted into the lower positioning groove, it can be threadedly connected to the lower positioning groove. The specific types of the upper fixing member 53 and the lower fixing member 63 are not limited in this embodiment.

[0064] Furthermore, in this embodiment, the specific number of upper positioning holes 511 and lower positioning holes 611 can be set according to design requirements. For example, the number of upper positioning holes 511 can be 5, and the number of lower positioning holes 611 can be 5; or, for another example, the number of upper positioning holes 511 can be 8, and the number of lower positioning holes 611 can be 8. This embodiment does not limit the specific number of positioning holes in this regard.

[0065] It should be noted that, in this embodiment of the application, the upper telescopic cylinder 51 is a hollow cylindrical structure.

[0066] Additionally, in some embodiments, such as Figure 5 and Figure 6 As shown, the upper telescopic component 50 includes an upper telescopic cylinder 51, an upper telescopic rod 52, and an upper locking member 54. One end of the upper telescopic cylinder 51 is connected to the upper bracket 31. The outer wall of the upper telescopic rod 52 is provided with multiple upper locking slots 521 at intervals along the axial direction of the upper telescopic rod 52. The upper telescopic rod 52 is embedded in the upper telescopic cylinder 51. One end of the upper telescopic rod 52 is connected to the upper positioning cylinder 32. The upper locking member 54 is rotatably connected to the end of the upper telescopic cylinder 51 away from the upper bracket 31. The upper locking member 54 is locked into one upper locking slot 52. 1; The lower telescopic component 60 includes a lower telescopic cylinder 61, a lower telescopic rod 62, and a lower locking component 64. One end of the lower telescopic cylinder 61 is connected to the lower bracket 41. The outer wall of the lower telescopic rod 62 is provided with a plurality of lower locking slots 621 at intervals along the axial direction of the lower telescopic rod 62. The lower telescopic rod 62 is embedded in the lower telescopic cylinder 61. One end of the lower telescopic rod 62 is connected to the lower positioning cylinder 42. The lower locking component 64 is rotatably connected to the end of the lower telescopic cylinder 61 away from the lower bracket 41. The lower locking component 64 is locked into a lower locking slot 621.

[0067] Since one end of the upper telescopic cylinder 51 is connected to the upper bracket 31, and the outer wall of the upper telescopic rod 52 is provided with multiple upper slots 521 at intervals along the axial direction of the upper telescopic rod 52, the upper telescopic rod 52 is embedded in the upper telescopic cylinder 51, and one end of the upper telescopic rod 52 is connected to the upper positioning cylinder 32. The upper locking member 54 is rotatably connected to the end of the upper telescopic cylinder 51 away from the upper bracket 31. Therefore, when it is necessary to adjust the distance between the upper positioning cylinder 32 and the upper bracket 31, force can be applied to the upper telescopic rod 52 to make the length of the upper telescopic rod 52 extending into the upper telescopic cylinder 51 different. Then, the upper telescopic rod 52 is moved to a suitable position, and the upper slot 521 is located at the end of the upper telescopic cylinder 51. The upper locking member 54 at the end of the upper telescopic cylinder 51 can be locked into the upper slot 521, so that the upper locking member 54 limits the upper telescopic rod 52. Specifically, when it is necessary to increase the distance between the upper positioning cylinder 32 and the upper bracket 31, force is applied to the upper telescopic rod 52, causing the upper telescopic rod 52 to move away from the upper telescopic cylinder 51. This reduces the length of the upper telescopic rod 52 extending into the upper telescopic cylinder 51, moving the upper telescopic rod 52 to a suitable position. With the upper slot 521 located at the end of the upper telescopic cylinder 51, the upper locking member 54 is engaged with the upper slot 521 to limit the movement of the upper telescopic rod 52, ensuring that the upper telescopic rod 52 does not move relative to the upper telescopic cylinder 51. When it is necessary to reduce the distance between the upper positioning cylinder 32 and the upper support 31, force is applied to the upper telescopic rod 52, causing the upper telescopic rod 52 to move closer to the upper telescopic cylinder 51. This increases the length of the upper telescopic rod 52 extending into the upper telescopic cylinder 51, moving the upper telescopic rod 52 to a suitable position. With the upper slot 521 located at the end of the upper telescopic cylinder 51, the upper locking member 54 is engaged with the upper slot 521, limiting the upper telescopic rod 52 and ensuring it does not move relative to the upper telescopic cylinder 51. In other words, by providing the upper telescopic cylinder 51, the upper telescopic rod 52, and the upper locking member 54, the distance between the upper positioning cylinder 32 and the upper support 31 can be easily adjusted.

[0068] Similarly, since one end of the lower telescopic cylinder 61 is connected to the lower support 41, the outer wall of the lower telescopic rod 62 is provided with multiple lower slots 621 at intervals along the axial direction of the lower telescopic rod 62. The lower telescopic rod 62 is embedded in the lower telescopic cylinder 61, and one end of the lower telescopic rod 62 is connected to the lower positioning cylinder 42. The lower locking member 64 is rotatably connected to the end of the lower telescopic cylinder 61 away from the lower support 41. Therefore, when it is necessary to adjust the distance between the lower positioning cylinder 42 and the lower support 41, force can be applied to the lower telescopic rod 62 to make the length of the lower telescopic rod 62 extending into the lower telescopic cylinder 61 different. Then, the lower telescopic rod 62 moves to a suitable position, and the lower slot 621 is located at the end of the lower telescopic cylinder 61. The lower locking member 64 at the end of the lower telescopic cylinder 61 can be locked into the lower slot 621, so that the lower locking member 64 limits the lower telescopic rod 62. Specifically, when it is necessary to increase the distance between the lower positioning cylinder 42 and the lower support 41, force is applied to the lower telescopic rod 62, causing the lower telescopic rod 62 to move away from the lower telescopic cylinder 61. This reduces the length of the lower telescopic rod 62 extending into the lower telescopic cylinder 61, moving the lower telescopic rod 62 to a suitable position. With the lower slot 621 located at the end of the lower telescopic cylinder 61, the lower locking piece 64 is engaged with the lower slot 621 to limit the lower telescopic rod 62, ensuring that the lower telescopic rod 62 does not move relative to the lower telescopic cylinder 61. When it is necessary to reduce the distance between the lower positioning cylinder 42 and the lower support 41, force is applied to the lower telescopic rod 62, causing the lower telescopic rod 62 to move closer to the lower telescopic cylinder 61. This increases the length of the lower telescopic rod 62 extending into the lower telescopic cylinder 61, moving the lower telescopic rod 62 to a suitable position. With the lower locking groove 621 located at the end of the lower telescopic cylinder 61, the lower locking member 64 is engaged with the lower locking groove 621, limiting the lower telescopic rod 62 and ensuring that it does not move relative to the lower telescopic cylinder 61. In other words, by providing the lower telescopic cylinder 61, the lower telescopic rod 62, and the lower locking member 64, the distance between the lower positioning cylinder 42 and the lower support 41 can be easily adjusted.

[0069] It should be noted that the upper telescopic cylinder 51 can be welded to the upper support 31. Alternatively, the upper telescopic cylinder 51 and the upper support 31 can be threaded together. That is, the upper support 31 has a threaded hole, and the outer wall of the upper telescopic cylinder 51 has threads. The upper telescopic cylinder 51 is then fitted into the threaded hole to achieve a threaded connection. The specific connection method between the upper telescopic cylinder 51 and the upper support 31 is not limited in this embodiment. Furthermore, the connection method between the lower telescopic cylinder 61 and the lower support 41 can be referenced from the connection method between the upper telescopic cylinder 51 and the upper support 31, and will not be repeated here.

[0070] Furthermore, the upper telescopic rod 52 and the upper positioning cylinder 32 can be welded together. Alternatively, they can be threaded together. The outer wall of the upper telescopic rod 52 is threaded, and the upper positioning cylinder 32 has a threaded hole. The upper telescopic rod 52 is fitted into the threaded hole to achieve the threaded connection. The specific connection method between the upper telescopic rod 52 and the upper positioning cylinder 32 is not limited in this embodiment. Additionally, the connection method between the lower telescopic rod 62 and the lower positioning cylinder 42 can be referenced from the connection method between the upper telescopic rod 52 and the upper positioning cylinder 32, and will not be repeated here.

[0071] Furthermore, in this embodiment, the number of upper slots 521 on the upper telescopic rod 52 can be set according to actual needs. For example, there can be 5 upper slots 521, spaced apart along the axial direction of the upper telescopic rod 52; or, for another example, there can be 8 upper slots 521, spaced apart along the axial direction of the upper telescopic rod 52. The specific number of upper slots 521 is not limited in this embodiment. Additionally, the number of lower slots 621 on the lower telescopic rod 62 can be set according to actual needs.

[0072] In addition, in this embodiment, the upper buckle and the end of the upper telescopic cylinder 51 can be movably connected by a pivot, so that the upper buckle can rotate relative to the upper telescopic cylinder 51; the lower buckle and the end of the lower telescopic cylinder 61 can be movably connected by a pivot, so that the lower buckle can rotate relative to the lower telescopic cylinder 61.

[0073] Additionally, in some embodiments, such as Figure 2 As shown, the upper telescopic member 50 also includes an upper support member 55, and the lower telescopic member 60 also includes a lower support member 65. One end of the upper support member 55 is connected to the upper bracket 31, and the other end of the upper support member 55 is connected to the upper telescopic cylinder 51. The axial direction of the upper support member 55 intersects with the axial direction of the upper telescopic cylinder 51 at an angle. One end of the lower support member 65 is connected to the lower bracket 41, and the other end of the lower support member 65 is connected to the lower telescopic cylinder 61. The axial direction of the lower support member 65 intersects with the axial direction of the lower telescopic cylinder 61 at an angle. With this arrangement, the upper support member 55, the upper telescopic cylinder 51, and the upper bracket 31 can form a triangle. The triangle has stability, which effectively stabilizes the upper telescopic cylinder 51 and avoids the problem of possible deformation of the upper telescopic cylinder 51. Similarly, the lower support 65, the lower telescopic cylinder 61, and the lower bracket 41 can form a triangle, which effectively stabilizes the lower telescopic cylinder 6 and prevents the lower telescopic cylinder 61 from deforming.

[0074] The upper support member 55 can be welded to the upper telescopic cylinder 51 and the upper bracket 31 respectively, and the lower support member 55 can be welded to the lower telescopic cylinder 61 and the lower bracket 41 respectively. Alternatively, the upper support member 55 can be bolted to the upper telescopic cylinder 51 and the upper bracket 31 respectively, and the lower support member 55 can be bolted to the lower telescopic cylinder 61 and the lower bracket 41 respectively. This embodiment of the application does not limit the specific implementation of this method.

[0075] In some embodiments, both the upper telescopic member 50 and the lower telescopic member 60 are hydraulic telescopic members. This arrangement avoids manual underwater installation and facilitates adjustment of the distance between the upper positioning cylinder 32 and the upper support 31, as well as the distance between the lower positioning cylinder 42 and the lower support 41.

[0076] It should be noted that hydraulic telescopic components can be jacks, but of course, they can also be other types, such as hydraulic cylinders.

[0077] Additionally, in some embodiments, such as Figure 1 or Figure 2 As shown, the piling positioning guide frame also includes a support platform 70, which is connected to the positioning frame 10 and is spaced apart from the upper support 31. The support platform 70 is located on the side of the upper guide platform 30 away from the lower guide platform 40. A drive assembly 80 is provided on the support platform 70. The upper support 31 is slidably connected to the positioning frame 10, and the drive assembly 80 is connected to the upper support 31. The drive assembly 80 is configured to drive the upper support 31 to slide relative to the positioning frame 10.

[0078] Since the support platform 70 is equipped with a drive assembly 80, the upper bracket 31 is slidably connected to the positioning frame 10, and the upper bracket 31 is connected to the drive assembly 80, the drive assembly 80 can drive the upper bracket 31 to move, causing the upper bracket 31 to move the upper positioning cylinder 32 relative to the positioning frame 10. That is, by applying force to the upper bracket 31 through the drive assembly 80, the upper bracket 31 moves relative to the positioning frame 10, and the upper bracket 31 can then drive the upper positioning cylinder 32 to move along the axial direction of the positioning frame 10. This allows the position of the upper positioning cylinder 32 in the axial direction of the positioning frame 10 to change. Furthermore, the upper positioning cylinder 32 and the upper bracket 31 are telescopically connected, allowing the position of the upper positioning cylinder 32 in the radial direction of the positioning frame 10 to change. This is equivalent to the upper positioning cylinder 32 being able to change position in two directions, allowing the position of the upper positioning cylinder 32 to be better adjusted as needed during piling, which is beneficial for piling. That is, by setting the drive component 80, the position of the upper positioning cylinder 32 can be easily adjusted in the axial direction of the positioning frame 10.

[0079] In addition, in this embodiment, a control component (not shown in the figure) can be installed on the support platform 70. The control component is electrically connected to the drive component 80. The control component controls the drive component 80, causing it to run. This causes the drive component 80 to exert force on the upper bracket 31, making the upper bracket 31 slide relative to the positioning frame 10. That is, the upper bracket 31 slides along the axis of the positioning frame 10. The upper bracket 31 can then drive the upper positioning cylinder 32 to move along the axis of the positioning frame 10, adjusting the position of the upper positioning cylinder 32. The control component can be a programmable logic controller (PLC). The control component and the drive component 80 are electrically connected via wires, allowing the control component to send control signals to the drive component 80 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 80 can be connected via Bluetooth.

[0080] In addition, in this embodiment, the drive component 80 can be a drive motor, which can be a servo motor or a stepper motor. The specific type of drive motor is not limited in this embodiment.

[0081] Furthermore, in this embodiment, the number of driving components 80 can be set according to actual needs. For example, if there are two driving components 80, 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 80, 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 80 is not limited in this embodiment.

[0082] In addition, in this embodiment, the drive assembly 80 can be bolted to the support platform 70. Of course, the housing of the drive assembly 80 can also be welded to the support platform 70. This embodiment does not limit the scope of the application.

[0083] Additionally, in some embodiments, such as Figure 1 or Figure 2 As shown, the drive component 80 is a motor, and the motor is connected to a traction rope 81. The traction rope 81 is connected to the upper bracket 31. The drive component 80 drives the traction rope 81 to move relative to the positioning frame 10, so that the traction rope 81 drives the upper bracket 31 to slide relative to the positioning frame 10.

[0084] Since the drive assembly 80 is connected to the traction rope 81, and the traction rope 81 is connected to the upper support 31, once the drive assembly 80 is running, it can apply force to the traction rope 81, causing the traction rope 81 to move relative to the positioning frame 10. Once the traction rope 81 moves, it can drive the upper support 31 to slide relative to the positioning frame 10, causing the upper support 31 to move the upper positioning cylinder 32 relative to the positioning frame 10. Furthermore, by setting the traction rope 81, while maintaining a certain distance between the drive assembly 80 and the sliding assembly, it is ensured that the drive assembly 80 can drive the upper support 31 to move relative to the positioning frame 10.

[0085] It should be noted that the traction rope 81 can be a steel wire rope to ensure that the traction rope 81 has greater strength and greater traction force. In addition, in this embodiment of the application, the traction rope 81 can also be formed of an iron chain, that is, the iron chain is equivalent to the traction rope 81, so that the sliding component can move relative to the positioning frame 10.

[0086] Additionally, in some embodiments, such as Figure 7 As shown, the output end of the motor is connected to a lead screw 82, and the extension direction of the lead screw 82 is parallel to the axis of the positioning frame 10. A slider 83 is provided on the lead screw 82, and the traction rope 81 is connected to the slider 83.

[0087] With this setup, once the motor starts, the output of the drive assembly 80 can drive the lead screw 82 to rotate. The slider 83 on the lead screw 82 can then move along the extension direction of the lead screw 82. Essentially, using the principle of the lead screw 82 and nut, the rotational motion of the lead screw 82 is converted into the linear motion of the slider 83. Since the extension direction of the lead screw 82 is parallel to the axis of the positioning frame 10, when the slider 83 moves relative to the lead screw 82, it can move along the axis of the positioning frame 10. Furthermore, the traction rope 81 is connected to the slider 83. Therefore, after the slider 83 moves, it can drive the traction rope 81 to move along the axis of the positioning frame 10, causing the traction rope 81 to move the upper support 31 along the axis of the positioning frame 10. In other words, by setting up the lead screw 82, the drive assembly 80 can be easily operated to move the upper support 31 relative to the positioning frame 10.

[0088] It should be noted that when the output end of the drive assembly 80 rotates and the lead screw 82 rotates in the first rotation direction, the slider 83 moves away from the drive assembly 80, which is equivalent to causing the upper support 31 to descend relative to the positioning frame 10. When the lead screw 82 rotates in the second rotation direction, the slider 83 moves closer to the drive assembly 80, which is equivalent to causing the upper support 31 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.

[0089] Additionally, in some embodiments, such as Figure 8 As shown, the output end of the motor is connected to a rope winder 84, and part of the traction rope 81 is wound around the rope winder 84. The axis of the rope winder 84 intersects the axis of the positioning frame 10 and has an angle.

[0090] With this configuration, once the motor is running, the output of the drive assembly 80 can drive the rope winder 84 to rotate, and part of the traction rope 81 is wound around the rope winder 84. Thus, as the rope winder 84 rotates, the traction rope 81 continues to wind around it, effectively applying force to the upper support 31, causing the upper support 31 to rise relative to the positioning frame 10, i.e., the upper support 31 slides upward relative to the positioning frame 10. Alternatively, as the rope winder 84 rotates, the traction rope 81 can separate from the rope winder 84, effectively causing the upper support 31 to descend relative to the positioning frame 10, i.e., the upper support 31 slides downward relative to the positioning frame 10. In short, by configuring the rope winder 84, the upper support 31 can move relative to the positioning frame 10 easily during the operation of the drive assembly 80.

[0091] It should be noted that the angle between the axis of the rope winder 84 and the axis of the positioning frame 10 can be 90 degrees, that is, the axis of the rope winder 84 is perpendicular to the axis of the positioning frame 10. Of course, the angle between the axis of the rope winder 84 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.

[0092] In addition, in this embodiment, the drive assembly 80 can also be connected to the upper bracket 31 via a traction rod. In this case, the drive assembly 80 drives the traction rod to move relative to the positioning frame 10, thereby causing the traction rod to cause the upper bracket 31 to slide relative to the positioning frame 10. Specifically, when the drive assembly 80 is connected to the upper bracket 31 via the traction rod, the traction rod can be connected to a slider 83 on a lead screw 82 connected to the output end of the drive assembly 80. This causes the slider 83 to move relative to the lead screw 82, thereby causing the traction rod to move relative to the positioning frame 10.

[0093] In some embodiments, the drive assembly 80 is an electric hoist connected to the upper support 31 to move the upper support 31 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 facilitating the installation of the piling positioning guide frame.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] Additionally, in some embodiments, such as Figure 1 or Figure 2As shown, the positioning frame 10 includes multiple columns 11 and multiple crossbeams 12; the multiple columns 11 are spaced apart, and the lines connecting the projections of the multiple columns 11 along the axis of the positioning frame 10 form 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 connect two columns 11 respectively. The axis of the crossbeams 12 is perpendicular to the axis of the columns 11; wherein, one end of the column 11 is connected to the fixed foundation 20.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] Additionally, in some embodiments, such as Figure 1 or Figure 2 As shown, at least two columns 11 are connected to the other end of a hoisting assembly 13, which is used to connect a hoisting device to hoist the positioning frame 10.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] Additionally, in some embodiments, such as Figure 1 or Figure 2 As shown, the positioning frame 10 also includes a plurality of 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.

[0107] 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.

[0108] 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.

[0109] Additionally, in some embodiments, such as Figure 2As 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.

[0110] 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.

[0111] 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 application embodiment does not limit this.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] In some embodiments, the positioning frame 10 is provided with a sliding groove, and the upper support 31 is connected to a pulley, which is embedded in the sliding groove, so that the upper support 31 is slidably connected to the positioning frame 10. With this arrangement, once the upper support 31 is subjected to force, it can apply force to the pulley, so that the pulley can slide in the sliding groove, causing the position of the upper support 31 relative to the positioning frame 10 to change. That is, by providing a sliding groove and a pulley, the upper support 31 can be easily slid relative to the positioning frame 10.

[0118] 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.

[0119] Of course, in this embodiment, a slide rail can also be provided on the positioning frame 10, and a pulley can be connected to the upper support 31, with the pulley embedded in the slide rail, so that the upper support 31 and the positioning frame 10 are slidably connected. Alternatively, a sliding groove can be provided on the positioning frame 10, and a slider 83 can be connected to the upper support 31, with the slider 83 embedded in the sliding groove, so that the upper support 31 and the positioning frame 10 are slidably connected. The specific connection method of the upper support 31 and the positioning frame 10 is not limited in this embodiment.

[0120] 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 level to fix the positioning frame 10, ensuring its stability. Furthermore, both the upper guide platform 30 and the lower guide platform 40 are connected to the positioning frame 10, and are spaced apart along the axial direction of the positioning frame 10. Therefore, when using the piling positioning guide frame, the lower guide platform 40 can be positioned below the sea level, and the upper guide platform 30 above the sea level; that is, the lower guide platform 40 is below the sea level, and the upper guide platform 30 is above the sea level. In addition, the upper guide platform 30 includes an upper support 31 and an upper positioning cylinder 32, and the lower guide platform 40 includes a lower support 41 and a lower positioning cylinder 42. The upper support 31 is connected to the positioning frame 10, and the upper positioning cylinder 32 is telescopically connected to the upper support 31. The lower support 41 is connected to the positioning frame 10, and the lower positioning cylinder 42 is telescopically connected to the lower support 41. Therefore, when positioning the steel pile, the position of the upper positioning cylinder 32 relative to the upper support 31 can be adjusted, and the position of the lower guide platform 40 relative to the lower support 31 can also be adjusted. The position of the frame 41 ensures that the upper positioning cylinder 32 and the lower positioning cylinder 42 are in suitable positions. Then, the steel pile is first inserted into the upper positioning cylinder 32, which can position the steel pile. Even if the steel pile extends below the sea surface, part of the steel pile is still located in the upper positioning cylinder 32. Thus, the upper positioning cylinder 32 can ensure that the steel pile is stably positioned by the upper positioning cylinder 32 when it is affected by ocean currents or waves. Since the upper positioning cylinder 32 is opposite to the lower positioning cylinder 42, the steel pile can enter the lower positioning cylinder 42.

[0121] That is, by setting up an upper guide platform 30 and a lower guide platform 40, with the upper positioning cylinder 32 of the upper guide platform 30 being telescopically connected to the upper support 31, and the lower positioning cylinder 42 of the lower guide platform 40 being telescopically connected to the lower support 41, the steel pile can be hoisted to the piling positioning guide frame by a hoisting device during piling. By adjusting the positions of the upper positioning cylinder 32 and the lower positioning cylinder 42, the upper positioning cylinder 32 is moved to a suitable position, and then the steel pile is inserted through the upper positioning cylinder 32. Located above the sea surface, the upper positioning cylinder 32 is not affected by ocean currents or waves, and the steel pile is also unaffected by ocean currents or waves above the sea surface. This facilitates the insertion of the steel pile through the upper positioning cylinder 32. After the steel pile extends below the sea surface, it is limited by the upper positioning cylinder 32. The upper positioning cylinder 32 and the lower positioning cylinder 42 are positioned opposite each other, thus the steel pile is effectively limited, facilitating its insertion into the lower positioning cylinder 42. The upper positioning cylinder 32 and the lower positioning cylinder 42 simultaneously limit the steel pile, facilitating subsequent pile driving and effectively improving pile driving efficiency.

[0122] This application provides a construction method applicable to the piling positioning guide frame in any of the above embodiments, such as... Figure 9 As shown, the construction method includes:

[0123] Step 901: Transport the piling positioning guide frame to the construction sea area, and adjust the position of the upper guide platform relative to the positioning frame according to the water depth so that the upper guide platform is above the sea level.

[0124] In this way, the drive component can be controlled to make the upper guide platform slide relative to the positioning frame, which is equivalent to making the sliding bracket slide to the set position. The sliding bracket is located above the sea surface, so that the upper positioning cylinder is located above the sea surface.

[0125] 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.

[0126] In addition, when transporting the piling positioning guide frame, the piling positioning guide frame can be placed horizontally, or it can be placed vertically.

[0127] Step 902: Place the piling positioning guide frame on the seabed surface by hoisting, and install the fixed foundation in place by suction installation.

[0128] The hoisting components on the positioning frame can be hoisted by a hoisting device, so that the piling positioning guide frame is lifted. Then, the piling positioning guide frame is placed in the seawater, so that the fixed foundation is located on the seabed surface. Then, the fixed foundation is installed by suction installation, so that the fixed foundation is installed in place.

[0129] Step 903: Insert one or more steel piles to be installed 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, install the pile hammer and pile driver, and begin the pile driving construction.

[0130] In some implementations, step 903 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 then the lower positioning cylinder; after the steel piles have sunk under their own weight, the upper guide platform is adjusted by the drive component to move it downwards until it is far 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 upper 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.

[0131] 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.
