Description

Technical Field

[0001] The present invention relates to the field of marine engineering technology, and in particular to a pile driving system and method. Background Art

[0002] The offshore wind power installation platform is generally composed of an upper platform structure, a lifting device, pile legs, and pile shoes. The pile shoes are connected to the pile legs and inserted into the seabed foundation to bear the deadweight and load of the entire platform to ensure the stable and safe operation of the platform. Usually, the pile shoes need to be inserted into the seabed foundation to a depth of more than ten meters or even deeper. When the work in this area is completed, the pile shoes need to be pulled up and moved to the next work point. However, due to the large surface area of ​​the pile shoes, the seabed soil layer is all adsorbed on the pile shoes, which increases the resistance to pile pulling. Therefore, the offshore wind power installation platform will be equipped with a pile flushing system to destroy the adsorption force of the seabed soil layer on the pile shoes, flush away the mud on the pile shoes, reduce the resistance to pile pulling, and make the pile pulling process go smoothly.

[0003] The pile driving system of traditional offshore wind power installation platforms is almost always composed of a main pile driving pipeline connected in series with multiple pile driving pipeline branches, and the pile driving pipeline branches are used to discharge water and drive piles at the corresponding positions of the corresponding pile shoes. However, during the pile driving process, the resistance of each pile driving pipeline branch is different. Some water outlet positions have smaller resistance and are flushed first. At this time, due to the appearance of the drainage channel, the water pressure in other pile driving pipeline branches will inevitably decrease, and the water outlet positions with greater soil resistance cannot be flushed. Therefore, the traditional pile driving system may fail to discharge water at some water outlet positions of the pile shoes, or the pile driving time may be too long, thereby affecting the work efficiency of the construction of offshore wind power installation platforms. Even when the positions that cannot discharge water are concentrated on the same side, it may cause serious overloading of the piles, resulting in the inability to pull out the pile shoes or other accidents and delays. Summary of the invention

[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0045] In the description of the present invention, it should be understood that the positive direction of "X" in the drawings represents the right, and correspondingly, the reverse direction of "X" represents the left; the positive direction of "Y" represents the front, and correspondingly, the reverse direction of "Y" represents the back; the positive direction of "Z" represents the top, and correspondingly, the reverse direction of "Z" represents the bottom. The orientation or position relationship indicated by the terms "X", "Y", "Z", etc. is based on the orientation or position relationship shown in the drawings of the specification, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0046] At present, the pile punching system at the pile shoe 1 is mostly composed of a pile punching pipeline main line connected in series with multiple pile punching pipeline branches, and the pile punching pipeline branches are used to discharge water at the corresponding positions of the pile shoe 1. However, during the pile punching process, the resistance of each pile punching pipeline branch is different, and the resistance of some water outlet positions is relatively small, so they are flushed first. At this time, due to the appearance of the drainage channel, the water pressure in other pile punching pipeline branches will inevitably decrease, and the water outlet positions with relatively large soil resistance cannot be flushed.

[0047] like Figure 1 As shown, an embodiment of the present invention provides a pile driving system, including a pile shoe 1, a detection device 8 and a water diversion assembly 2, wherein the pile shoe 1 is provided with a plurality of first water outlets 11; the detection device 8 is used to detect the water output of each of the first water outlets 11; the water diversion assembly 2 is arranged in the pile shoe 1, and the water diversion assembly 2 is provided with a first water inlet 21 and a plurality of second water outlets 22; each of the second water outlets 22 is suitable for being connected with one of the first water outlets 11 through a pipeline; the water diversion assembly 2 includes an adjusting mechanism, and the adjusting mechanism is used to cause the first water inlet 21 to communicate with at least one of the second water outlets 22.

[0048] After adopting the pile driving system of the present invention, at the beginning of the pile driving work, the regulating mechanism is used to cause the first water inlet 21 to communicate with all the second water outlets 22, and the detection device 8 can be used to detect the water output of each first water outlet 11, so as to determine whether the water output of each first water outlet 11 is qualified; when the water output of at least one first water outlet 11 is less than the preset water output, the regulating mechanism is used to cause the first water inlet 21 to communicate with the first water outlet 11 that needs to be unblocked in sequence, and finally achieve that the water output of all the first water outlets 11 is greater than or equal to the preset water output, that is, the pile driving of the pile shoe 1 is successfully completed, thereby improving the work efficiency of constructing the offshore wind power installation platform, avoiding serious pile pulling eccentricity, the inability to pull out the pile shoe 1 and other accidents and delays.

[0049] In this embodiment, the regulating mechanism first causes the first water inlet 21 to communicate with all the second water outlets 22, and can screen out the first water outlet 11 (hereinafter referred to as the unqualified first water outlet 11) whose water output is less than the preset water output through the detection device 8, and then causes the first water inlet 21 to communicate with the second water outlet 22 corresponding to the unqualified first water outlet 11, and concentrates the water pressure to flush the unqualified first water outlet 11, thereby causing the water output of the unqualified first water outlet 11 to be greater than or equal to the preset water output.

[0050] In this embodiment, Figure 1As shown, the water distribution component 2 is arranged at the center of the pile shoe 1. The pile driving main pipe of the traditional pile driving system needs to be laid along the longitudinal and transverse directions of the pile shoe 1. The main pipe is long and heavy, which is inconvenient to arrange. After the water distribution component 2 is arranged at the center of the pile shoe 1, the length of the pile driving main pipe can be effectively reduced, the weight of the pipe can be reduced, and the arrangement can be convenient.

[0051] Optionally, the water distribution component 2 further includes a shell 24, the shell 24 is provided with a cavity 25, the first water inlet 21 and the plurality of second water outlets 22 are all connected to the cavity 25; the regulating mechanism is located in the cavity 25. Thus, the regulating mechanism adjusts the communication state of the first water inlet 21 and the plurality of second water outlets 22 from the inside of the shell 24, and the structure is more reasonable.

[0052] In one embodiment, if Figure 2 As shown, the housing 24 includes a first shell 241 and a second shell 242 . The first shell 241 is suitable for being detachably connected to the second shell 242 . The cavity 25 is formed between the first shell 241 and the second shell 242 .

[0053] In one embodiment, the first shell 241 is provided with a hollow groove structure. After the first shell 241 and the second shell 242 are assembled, a cavity 25 is formed on the upper surface of the hollow groove structure and the second shell 242 .

[0054] In another embodiment, the first shell 241 is provided with a first groove structure, and the second shell 242 is provided with a second groove structure. After the first shell 241 and the second shell 242 are assembled, the first groove structure and the second groove structure form a cavity 25.

[0055] In the two embodiments of the above-mentioned shell 24, a first plate 2411 with holes is provided on the outer wall of the first shell 241, and a second plate 2421 with holes is provided at corresponding positions on the outer wall of the second shell 242. The holes of the first plate 2411 and the second plate 2421 are fixed by a connecting member 27. Specifically, the connecting member 27 is a bolt assembly, and the bolts of the bolt assembly pass through the holes of the first plate 2411 and the second plate 2421 in sequence and are locked by the nuts of the bolt assembly.

[0056] In this embodiment, the first water inlet 21 is located on the first housing 241. Figure 1 , 4 As shown, the upper end surface of the first shell 241 is square, the first water inlet 21 is located at the center of the first shell 241, and the first water inlet 21 is connected to the first water injection pipe 4.

[0057] In this embodiment, the second water outlet 22 is located on the second housing 242. Figure 1 , 6As shown, the lower end surface of the second shell 242 is square, and a plurality of second water outlets 22 are distributed in a circle on the second shell 242 and communicate with the first water outlet 11 through a pipeline.

[0058] Alternatively, if Figure 2 As shown, the adjusting mechanism includes a wheel disc 23, a lifting device 26, and a power device 28; the wheel disc 23 is provided with a through hole 231; the fixed end of the lifting device 26 is connected to the cavity 25, and the telescopic end of the lifting device 26 is suitable for being detachably connected to the wheel disc 23; the power device 28 is suitable for driving the wheel disc 23; when the telescopic end is connected to the wheel disc 23, the lifting device 26 is suitable for driving the wheel disc 23 to rise and fall, so as to cause the wheel disc 23 to contact or separate from a side of the cavity 25 where the second water outlet 22 is provided; when the telescopic end is separated from the wheel disc 23, the power device 28 is suitable for driving the wheel disc 23 to rotate.

[0059] Specifically, if Figure 3 , 5 As shown, the outer circumferential edge of the wheel disc 23 is provided with a first latching tooth 232, and the power device 28 includes a motor and a matching piece with a second latching tooth arranged at the motor shaft of the motor, and the first latching tooth 232 is meshed with the second latching tooth. Therefore, when the motor moves, the wheel disc 23 will follow it to make a circular motion because the first latching tooth 232 and the second latching tooth are in a meshing relationship.

[0060] In this embodiment, the matching part is a plate structure, and the motor is fixed on the second shell 242. In one implementation, the motor is provided with a motor seat, and the motor seat is fixedly connected to the second shell 242 by screws. The motor is fixed on the motor seat, thereby achieving the stability of the motor on the second shell 242.

[0061] In this embodiment, the second housing 242 includes a first positioning member 251, and the wheel disc 23 includes a second positioning member 233 that cooperates with the first positioning member 251. The second housing 242 is suitable for positioning the rotation position of the wheel disc 23 through the first positioning member 251 and the second positioning member 233. Thus, it is convenient for the power device 28 to drive the wheel disc 23 to perform circular motion.

[0062] In this embodiment, the first positioning member 251 is located at the center of the second housing 242. Therefore, when the first positioning member 251 is set at the center of the second housing 242, the wheel 23 can make a circular motion, and will not be out of engagement with the motor due to eccentricity.

[0063] Specifically, the first positioning member 251 is a positioning pin, and the second positioning member 233 is a positioning hole; or, the first positioning member 251 is a positioning hole, and the second positioning member 233 is a positioning pin, and the positioning pin is inserted into the positioning hole; the above two implementation modes are determined according to actual needs, preferably, as Figure 4 , 5 As shown, the first positioning member 251 is a positioning pin, and the second positioning member 233 is a positioning hole. The positioning pin is inserted into the positioning hole. Therefore, when the motor drives the wheel 23 to move, the wheel 23 moves in a circle around the positioning pin to prevent the wheel 23 from being offset.

[0064] In other embodiments, an electric cylinder is embedded in the second shell 242, and the telescopic end of the electric cylinder is connected to the wheel disc 23. Specifically, the wheel disc 23 is provided with a socket, and the telescopic end of the electric cylinder is inserted into the socket. The socket limits the axial displacement of the telescopic end of the electric cylinder on the wheel disc 23, but the wheel disc 23 can rotate around the telescopic end of the electric cylinder.

[0065] Optionally, the wheel disc 23 is provided with an ear plate structure 234 with a first hole structure, and the telescopic end of the lifting device 26 is provided with a second hole structure; the pile punching system further comprises a driving assembly 7 and a plug-in pin 6, and the driving assembly 7 is adapted to drive the plug-in pin 6 to move so as to pass through the first hole structure and the second hole structure. Thus, the driving assembly 7 drives the plug-in pin 6 to move, and the locking and unlocking between the wheel disc 23 and the power device 28 can be realized, so that the movement mode of the wheel disc 23 can be selected according to the working requirements.

[0066] In this embodiment, the ear plate structure 234 includes a base plate and two support plates, the two support plates are provided with first hole structures of equal height, and the two support plates are spaced apart on the base plate; the telescopic end of the drive assembly 7 is provided with a matching block 261 with a second hole structure, and the matching block 261 can extend between the two support plates, so that the two first hole structures and one second hole structure are coaxially arranged, which is convenient for the insertion of the plug-in pin 6.

[0067] In one embodiment, the driving component 7 is an electric cylinder, which is fixed on the wheel disc 23. The telescopic end of the electric cylinder is connected to the plug-in pin 6, and the plug-in pin 6 faces the first hole structure and the second hole structure. Therefore, when the wheel disc 23 needs to be lifted, the electric cylinder drives the plug-in pin 6 to move, and the plug-in pin 6 passes through the first hole structure and the second hole structure to connect the wheel disc 23 and the driving component 7 together; when the wheel disc 23 needs to be rotated, the electric cylinder drives the plug-in pin 6 to move, and the plug-in pin 6 disengages from the second hole structure. After the telescopic end of the driving component 7 moves up a certain distance, it can avoid affecting the rotation of the wheel disc 23.

[0068] In this embodiment, the lifting device 26 is disposed on the first housing 241, and can be rotatably connected to the first housing 241 or fixedly connected to the first housing 241, depending on actual needs. Since the first water inlet 21 is disposed at the center of the first housing 241, in order to facilitate the stable lifting of the wheel 23, a plurality of lifting devices 26 are provided, and are symmetrically disposed along the first water inlet 21, such as Figure 2 As shown, two lifting devices 26 are provided, and the two lifting devices 26 are symmetrically arranged along the first water inlet 21 .

[0069] Optionally, the detection device 8 is a flow meter, and the detection device 8 is disposed at the first water outlet 11. Thus, the water flow at the first water outlet 11 can be determined by the flow meter, thereby determining the resistance at the first water outlet 11.

[0070] Optionally, the pile driving system further comprises a first nozzle 12, a plurality of the first water outlets 11 are evenly distributed on the pile shoe 1, and the first nozzle 12 is arranged at the first water outlet 11. Thus, the first water outlets 11 are evenly distributed, so that the pile shoe 1 discharges water evenly, and at the same time, the first water outlet 11 is provided with the first nozzle 12, so that the first water outlet 11 can be protected and soil can be prevented from entering the first water outlet 11.

[0071] In this embodiment, the first nozzles 12 are evenly distributed on the upper and lower surfaces of the pile shoe 1 in a ring-shaped distribution, and the total area of ​​all the first nozzles 12 is 1%-10% of the surface area of ​​the pile shoe 1.

[0072] Optionally, the pile driving system further comprises a pile leg 3, the pile shoe 1 is arranged at the lower end of the pile leg 3; the pile leg 3 is provided with a second water inlet and a plurality of third water outlets 31, and the second water inlet and the plurality of third water outlets 31 are suitable for being connected through a pipeline. Thus, the arrangement of the pile leg 3 can flush away the soil attached to the cylinder of the pile leg 3, reduce the pile pulling resistance, shorten the pile pulling time, and improve the working efficiency of the wind power installation platform.

[0073] In this embodiment, a second water injection pipe connected to the second water inlet is provided on the outside of the pile leg 3, and a water distribution main pipe 5 connected to the second water inlet is provided on the inside of the pile leg 3. The water distribution main pipe 5 is connected to each third water outlet 31 through a branch pipe. Therefore, when water is injected through the second water injection pipe, it flows through the water distribution main pipe 5 and then flows to each third water outlet 31 through the branch pipe.

[0074] Optionally, the pile driving system further comprises a second nozzle 32, a plurality of the third water outlets 31 are evenly distributed on the pile leg 3, and the second nozzle 32 is arranged at the third water outlet 31. Thus, the third water outlets 31 are evenly distributed, which facilitates the uniform water discharge of the pile shoe 1. Meanwhile, the third water outlet 31 is provided with the second nozzle 32, which can protect the third water outlet 31 and prevent soil from entering the third water outlet 31.

[0075] Optionally, the pile driving system also includes a controller 9, which is electrically connected to the detection device 8, the power device 28, the lifting device 26 and the drive assembly 7 respectively, and is used to receive water output information transmitted by the detection device 8, control the movement of the power device 28, control the lifting of the lifting device 26 and the movement of the drive assembly 7.

[0076] It should be noted that the controller 9 is only used in an optional implementation. Since the detection device can be a flow meter with a digital display, in other implementations, the operator can also perform corresponding operations according to the flow meter reading.

[0077] The principle of the pile punching system of the present invention is as follows:

[0078] During the working process, high-pressure water is introduced into the first water injection pipe 4 and the second water injection pipe at the same time. The high-pressure water enters the water distribution assembly 2 in the pile shoe 1 through the first water injection pipe 4, and the lifting device 26 lifts the wheel disc 23 to separate the wheel disc 23 from the second shell 242. The high-pressure water flows from the second water outlet 22 through the pipeline to each first water outlet 11, and then punches the pile through the first nozzle 12, and the value change of the flow meter at each first nozzle 12 is recorded. At this time, some flow meters show that the first nozzle 12 has discharged water, and some flow meters show that the first nozzle 12 has not discharged water, and the number of the first nozzle 12 that has not discharged water is recorded. The wheel disc 23 is dropped by the lifting device 26 to close the wheel disc 23 and the second shell 242. According to the recorded number of the first nozzle 12 that has not discharged water, the through hole 231 of the wheel disc 23 is aligned with the corresponding second water outlet 22 in turn by the driving component 7, and the first nozzle 12 that has not discharged water is flushed separately until the flow meter shows that the nozzle has discharged water. The reciprocating operation is performed to ensure that all the first nozzles 12 of the pile shoe 1 are flushed; at the same time, high-pressure water enters the water distribution main pipe 5 in the pile leg 3 through the second water injection pipe, and after passing through the water distribution main pipe 5, it flows to each third water outlet 31 through the branch pipe, and then flushes the pile through the second nozzle 32.

[0079] An embodiment of the present invention further provides a pile driving method, comprising:

[0080] S1, controlling the regulating mechanism of the pile driving system so that the first water inlet 21 of the pile shoe 1 of the pile driving system is connected with all the second water outlets 22 of the pile driving system;

[0081] S2, controlling water inlet of the first water inlet 21, and detecting water output of each of the first water outlets 11;

[0082] S3. When the water output of at least one of the first water outlets 11 is less than a preset water output, the regulating mechanism is adjusted to make the water output of all the first water outlets 11 greater than or equal to the preset water output.

[0083] Step S1 includes: controlling the lifting device 26 of the adjusting mechanism to lift the wheel disc 23 of the adjusting mechanism, so that the wheel disc 23 is separated from the second shell 242 of the pile driving system, so that the first water inlet 21 of the pile driving system is connected with all the second water outlets 22 of the pile driving system.

[0084] Step S2 includes: after the first water outlets 11 continue to impact the pile for a preset time, controlling the detection device 8 of each first water outlet 11 to work and detecting the water output of each first water outlet 11 .

[0085] In this step, the preset time is generally 5-10 minutes.

[0086] In step S3, for the convenience of description, the following defines water output less than the preset water output as unqualified water output, and water output greater than or equal to the preset water output as qualified water output. When the water output of the first water outlet 11 is unqualified, the first water outlet 11 with unqualified water output is prioritized, and the wheel 23 is dropped by the lifting device 26 to close the wheel 23 and the second shell 242. According to the order of priority sorting, the through hole 231 of the wheel 23 is aligned with the corresponding second water outlet 22 in sequence by the driving component 7, and the first water outlet 11 with unqualified water output is flushed separately until the flow meter shows that the water output of the first water outlet 11 is qualified, and the reciprocating operation is performed to ensure that the water output of the first water outlet 11 with unqualified water output is qualified.

[0087] In this embodiment, the first water outlet 11 with unqualified water output can be classified according to the criticality of the position, that is, the critical position and the non-critical position. When the second operation is executed, the key position is given priority, and the piles are flushed in sequence according to the principle of large to small flow rate, and the proportion of water outlet nozzles in the key position must reach 100%. Then the non-critical position nozzles are flushed, and the principle of large to small flow rate is followed, and the proportion of water outlet nozzles in the non-critical position can reach 80%.

[0088] Meanwhile, if it is detected that the water output of a first water outlet 11 with unqualified water output is still unqualified after a period of continuous pile flushing, the next first water outlet 11 with unqualified water output is flushed with reference to the priority sorting.

[0089] Although the disclosure is disclosed as above, the protection scope of the disclosure is not limited thereto.
