[0037] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.
[0038] like Figure 1-Figure 3 As shown, the present invention provides an underwater pile driving guide device for underwater pile driving operation. The underwater pile driving guide device comprises a guide structure 1, a plurality of adjustment cylinders 2, a plurality of support assemblies 3, a plurality of first limit members 4 and a plurality of second limit members 5. Among them, the guide structure 1 includes a guide cylinder 11, and the pipe pile can pass through the guide cylinder 11 along the penetration direction of the guide cylinder 11; multiple adjustment cylinders 2 are symmetrically distributed about the center of the guide cylinder 11 and are fixedly arranged relative to the guide cylinder 11, and the penetration direction of the adjustment cylinder 2 is parallel to the penetration direction of the guide cylinder 11; the supporting assembly 3 includes an adjusting rod 31 and a support plate 32, the adjusting rod 31 is fixedly arranged on the support plate 32, the adjusting rod 31 can pass through the adjusting cylinder 2, and a plurality of limiting holes 310 are spaced apart in the vertical direction on the adjusting rod 31, the support plate 32 can be pressed against the seabed, and the supporting assembly 3 corresponds to the adjusting cylinder 2 one by one; a first limiting member 4 can extend into any limiting hole 310 and abut against the bottom end of the adjusting cylinder 2, and the first limiting member 4 corresponds to the adjusting rod 31 one by one; a second limiting member 5 can extend into any limiting hole 310 and abut against the top end of the adjusting cylinder 2, and the second limiting member 5 corresponds to the adjusting rod 31 one by one.
[0039] The adjusting cylinder 2 and the supporting assembly 3 cooperate with each other. When the slope of the seabed is large, the relative positions of the adjusting cylinder 2 and the adjusting rod 31 can be adjusted by the first limit member 4 and the second limit member 5 to ensure that the pipe piles in the guide cylinder 11 are in a vertical state while the support plate 32 can still be pressed against the seabed. The adjustment range is large and it can be suitable for seabeds with large slopes. At the same time, the structure is simple and the manufacturing cost is low.
[0040] It should be noted that the support plate 32 can be partially buried in the mud and sand on the seabed as long as the stability of the guide structure 1 can be guaranteed.
[0041] For example, in this embodiment, four supporting assemblies 3 are provided, and correspondingly, four adjusting cylinders 2 are provided, and eight first stoppers 4 and second stoppers 5 are provided. In other embodiments, the number of supporting assemblies 3 can be adjusted according to actual needs, and is not specifically limited here.
[0042] For example, in this embodiment, 14 limiting holes 310 are spaced apart on one adjusting rod 31 , the distance between two adjacent limiting holes 310 is 200 mm, and the diameter of each limiting hole 310 is 89 mm.
[0043] In this embodiment, when the position of the first limiting member 4 rises or falls by one limiting hole 310 , the guide cylinder 11 can rotate 0.86° relative to the vertical direction.
[0044] Illustratively, in this embodiment, both the first position-limiting member 4 and the second position-limiting member 5 are pin structures commonly used in the art, and both are provided with handles for easy holding.
[0045] Specifically, the guide structure 1 further includes a connecting frame 12 , and the connecting frame 12 is fixedly disposed between the guide cylinder 11 and the adjustment cylinder 2 .
[0046] For example, in this embodiment, the connecting frame 12 is a triangular truss structure commonly used in the art.
[0047] Specifically, the underwater pile driving guide device further includes a connecting rod 6, which is disposed between two adjacent support plates 32, one end of the connecting rod 6 being rotatably connected to one support plate 32, and the other end being rotatably connected to the other support plate 32. The arrangement of the connecting rod 6 can prevent the two adjacent support plates 32 from moving relative to each other in the horizontal direction under the action of the water flow, thereby improving the stability of the support plates 32.
[0048] Specifically, a plurality of connecting rods 6 are arranged between two adjacent support plates 32. The above arrangement makes the force on the support plates 32 more balanced, thereby further improving the stability of the support plates 32.
[0049] Specifically, the underwater pile driving guide device further includes a locking assembly 7, which includes a locking rod 71 and two locking blocks 72. The supporting assembly 3 further includes an adapter seat 33, which is provided with an adapter groove 331 and a first adapter hole 332. The first adapter hole 332 is connected to the adapter groove 331. The end of the connecting rod 6 is provided with a second adapter hole. When the end of the connecting rod 6 extends into the adapter groove 331, the first adapter hole 332 is connected to the second adapter hole. The locking rod 71 can pass through the first adapter hole 332 and the second adapter hole at the same time. The two locking blocks 72 are screwed to the two ends of the locking rod 71 in a one-to-one correspondence. The locking blocks 72 can abut against the outer wall of the adapter seat 33. The above-mentioned setting of the locking assembly 7 can realize the rotational connection between the support plate 32 and the connecting rod 6, and the locking rod 71 can be rotationally connected to the adapter seat 33 or separated from the adapter seat 33 by rotating the locking block 72, which is simple and convenient to operate.
[0050] More specifically, each end of the connecting rod 6 is provided with two connecting parts, and two transfer grooves 331 are provided on an adapter seat 33 at intervals. The connecting parts can be inserted into the transfer grooves 331 one by one to improve the connection strength between the connecting rod 6 and the adapter seat 33.
[0051] Illustratively, in this embodiment, the locking block 72 is a nut structure commonly used in the art, so as to facilitate local material acquisition.
[0052] More specifically, the first adapter hole 332 is long and narrow in the length direction of the connecting rod 6. When encountering water flow impact, the connecting rod 6 can slide along the length direction of the first adapter hole 332 driven by the locking rod 71 to buffer the impact force of the water flow and improve the durability of the structure.
[0053] Specifically, the top of the guide tube 11 is in a trumpet shape. The above arrangement facilitates the insertion of the pipe pile into the guide tube 11.
[0054] Specifically, the outer circumference of the guide tube 11 is provided with an extension opening 10, which is connected to the guide tube 11 and extends in the vertical direction, so that the anchor chain of the pile can pass through the guide tube 11 from the extension opening 10. The above arrangement facilitates the extension of the anchor chain.
[0055] It should be noted that if the extension opening 10 is directly opposite to between the two support plates 32 , then the connecting rod 6 may not be provided between the two support plates 32 to prevent the connecting rod 6 from interfering with the anchor chain.
[0056] More specifically, a limit plate is provided on the pipe pile, and the limit plate can pass through the extension opening 10 and abut against the guide cylinder 11. The provision of the limit plate can prevent the pipe pile from self-rotating during the piling process.
[0057] Specifically, the support plate 32 is provided with a lifting lug 321. The provision of the lifting lug 321 facilitates the lifting of the support plate 32.
[0058] More specifically, the plurality of lifting ears 321 are distributed symmetrically about the guide tube 11 so that the support plate 32 will not be skewed during the lifting process.
[0059] Specifically, the support plate 32 is provided with a plurality of mud discharge holes 322 extending vertically therethrough. When the support plate 32 is pressed against the seabed, loose mud on the seabed can be discharged through the mud discharge holes 322 to improve the stability of the support plate 32.
[0060] Optionally, the support plate 32 is provided with a high-pressure water injection device. When the support plate 32 is pressed against the seabed, the high-pressure water injection device can inject high-pressure water into the seabed to facilitate the discharge of silt from the mud discharge hole 322. The above-mentioned high-pressure water injection device is a prior art in this field, and its specific structure and principle are not repeated here.
[0061] The specific implementation method of the underwater pile driving guide device is described in detail below. The use method includes the following steps:
[0062] S1. Insert the first limiting members 4 into the limiting holes 310 on the adjusting rod 31 one by one, and the heights of the first limiting members 4 are equal.
[0063] S2, sleeve the plurality of adjusting cylinders 2 on the adjusting rod 31 in a one-to-one correspondence, so that the bottom of the adjusting cylinder 2 abuts against the first limiting member 4.
[0064] S3, inserting the second limiting members 5 into the limiting holes 310 on the adjusting rods 31 one by one, so that the second limiting members 5 abut against the top of the adjusting tube 2.
[0065] S4. Hoist the support plate 32 so that the support plate 32 abuts against the seabed surface.
[0066] S5. Measure the inclination angle of the guide tube 11 relative to the vertical direction.
[0067] S6. Adjust the height of the guide tube 11 relative to the adjustment rod 31 so that the guide tube 11 extends in the vertical direction.
[0068] In the above steps, the support plate 32 can be lifted out of the water first, and the corresponding limiting hole 310 can be changed by extracting and inserting the first limiting member 4 and the second limiting member 5 to achieve height adjustment of the adjusting tube 2 relative to the adjusting rod 31.
[0069] The above steps S4 to S6 may be repeated multiple times until the inclination angle of the guide tube 11 relative to the vertical direction meets the actual demand.
[0070] S7, passing the pipe pile through the guide tube 11 to carry out subsequent piling operations.
[0071] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
