Description

Technical Field

[0001] This application relates to the field of offshore construction equipment technology, and in particular to a pile stabilization platform that can be quickly positioned. Background Technology

[0002] As my country's social standards continue to improve and people's lives become richer, the demand for various resources, such as electricity and natural gas, is increasing. Due to the limited land resources, the development of marine energy has become the main way to meet the growing demand.

[0003] Modern society's development of marine resources includes numerous marine engineering projects such as the construction of offshore photovoltaic power stations, the extraction of seabed natural gas, and the utilization of offshore wind power. Whether building an offshore photovoltaic power station or constructing an offshore resource extraction platform, the construction of steel pipe pile foundations is required. Due to the instability of ocean currents, high-strength pipe piles are needed to improve stability. In existing technologies, the installation of offshore steel pipe piles is carried out through offshore working platforms. After the construction team erects the offshore working platform, the pipe piles are transported to the platform by ship for driving. This effectively improves the problem of ocean currents causing the pipe piles to deviate from the preset driving point during the driving process. After driving piles at one construction site, the offshore working platform needs to be dismantled and transported to the next construction site for reassembly to construct another offshore steel pipe pile foundation.

[0004] Regarding the aforementioned technologies, the inventors have found that the existing technology for the construction of offshore steel pipe piles is rather cumbersome, requiring repeated assembly and disassembly of the offshore operation platform, resulting in high labor intensity, long construction period, and significantly reduced construction efficiency, thus requiring improvement. Summary of the Invention

[0005] To simplify the construction process of offshore steel pipe piles, improve pile driving efficiency, reduce labor intensity, and shorten the construction cycle, this application provides a pile stabilization platform that can be quickly positioned.

[0006] The pile stabilization platform that can be quickly positioned according to this application adopts the following technical solution: A rapidly positioning stabilizing platform includes a platform body. Each side edge of the platform body is equipped with a stabilizer. Each stabilizer includes a positioning tube, a first hydraulic cylinder, a support pile, a second hydraulic cylinder, and a connecting pile. The positioning tube is vertically connected to the side edge of the platform body. The first hydraulic cylinder is connected to the inner wall of the positioning tube. The support pile is connected to the piston rod of the first hydraulic cylinder. The first hydraulic cylinder drives the support pile to slide along the length of the positioning tube. The support pile is used to abut against the seabed. The second hydraulic cylinder is positioned above the first hydraulic cylinder. The connecting pile is connected to the piston rod of the second hydraulic cylinder. The support pile has a passage hole along its height for the connecting pile to pass through. The second hydraulic cylinder drives the connecting pile through the passage hole and inserts it into the seabed sediment. Each side wall of the platform body is equipped with a vertically positioned lower pile tube.

[0007] By adopting the above technical solution, the platform body is propelled by a vessel carrying pipe piles and positioned at the bottom of the vessel. Upon arrival at the construction site, the vessel lowers the platform body until it sinks to the bottom of the water. The first hydraulic cylinder drives the support piles to contact the seabed. After contact is completed, the second hydraulic cylinder drives the insertion piles to be inserted into the seabed sediment, thus positioning the platform body. Subsequently, the pipe piles can be aligned with the lowering pipe to carry out the pile driving. After construction is completed, the platform body can be quickly recovered by simply using the second hydraulic cylinder to drive the insertion piles to detach from the seabed sediment. This saves the time of repeatedly building offshore operating platforms in existing technologies, reduces workload, shortens the construction cycle, and greatly improves the efficiency of offshore steel pipe construction.

[0008] Optionally, the platform body has several ballast water inlets on its sidewalls, each ballast water inlet is equipped with a filter screen, and the platform body has several ballast water tanks inside, each ballast water tank being connected to at least one ballast water inlet. The platform body is equipped with a control module, and the several ballast water inlets are controlled by the control module. The bottom wall of the platform body is equipped with a buoyancy detection module for detecting the buoyancy force on the platform body. The buoyancy detection module is electrically connected to the control module. The buoyancy detection module is used to detect the buoyancy force on the platform body in real time and send the buoyancy value to the control module. The control module opens the ballast water inlets based on the buoyancy value to balance the buoyancy force on the platform body.

[0009] By adopting the above technical solution, the salinity of the seawater varies in different construction sites, resulting in slight deviations in the buoyancy of the seawater. To improve the construction convenience of the stabilizing platform of this application, the stabilizing platform is made of lightweight materials. Since the buoyancy of seawater varies in different sea areas, the stabilizing platform may not be able to sink to the seabed. By setting up ballast water tanks and using ballast water to increase the self-weight of the platform body, the platform body can sink to the seabed. After the construction is completed, the ballast water is discharged, and the platform body can float to the surface, further improving the construction efficiency and applicability of the stabilizing platform of this application.

[0010] Optionally, each side wall of the platform body is provided with a plurality of balancing propellers, and the plurality of balancing propellers are controlled by a control module. The top wall of the platform body is provided with a level detection module for monitoring the levelness of the platform body. The level detection module is electrically connected to the control module. The level detection module is used to monitor the levelness of the platform body in real time and send the detection value to the control module. The control module activates the corresponding balancing propellers based on the detection value to balance the platform body.

[0011] By adopting the above technical solution, the platform body will deviate to a certain extent in the direction of ocean current movement during the process of sinking into the seabed, which will prevent the platform body from being set vertically. At this time, the level detection module detects the levelness of the platform body, and after analysis by the control module, the corresponding balancing propeller is selected to be started to counteract the force of the ocean current in that direction. Thus, by using different rotation speeds of multiple balancing propellers, the platform body can maintain balance during the descent, so that the subsequent pipe piles can also be driven vertically. It has high precision and practicality.

[0012] Optionally, the support pile includes a movable part and several abutting parts. The movable part is connected to the piston rod of the first hydraulic cylinder. A clearance slope is provided on the side wall of one end of the movable part extending out of the positioning tube. Several abutting parts are hinged to the clearance slope. Several hidden holes are provided on the surface of the clearance slope corresponding to the abutting parts. A third hydraulic cylinder is provided in each hidden hole. The third hydraulic cylinder is controlled by a control module. The base of the third hydraulic cylinder is hinged to the bottom wall of the hidden hole. The piston rod of the third hydraulic cylinder is hinged to the side wall of the corresponding abutting part. A pressure detection module is provided on the bottom wall of each abutting part. The pressure detection module is electrically connected to the control module. The pressure detection module is used to detect the pressure value on the bottom wall of the abutting part in real time and send it to the control module. The control module controls the corresponding third hydraulic cylinder to start based on the pressure value, so as to drive the abutting part to abut against the seabed.

[0013] By adopting the above technical solution, when the support pile abuts against the seabed, the unevenness of the seabed can cause the support pile to not be firmly connected, which can easily lead to the platform body sliding or even collapsing. By setting an abutment part at the bottom of the support pile, and using a pressure detection module on the abutment part to detect the pressure on the bottom wall of the abutment part in real time, if the pressure value is too high, it means that the abutment part is over-attached, and the third hydraulic cylinder can drive the abutment part to rotate away from the seabed; if the pressure value is too low, it means that the abutment part is not fully abutted, and the third hydraulic cylinder can drive the abutment part to rotate towards the seabed until it is firmly abutted, so that the support pile of this application can fully abut against the seabed, improving the stability of the platform body.

[0014] Optionally, the bottom wall of the plug-in pile is provided with a driving hole, a lifting component is provided in the driving hole, the movable end of the lifting component moves along the depth direction of the driving hole, the movable end of the lifting component is connected to a rotating component, and the output shaft of the rotating component is connected to a hole-reaming drill bit.

[0015] By adopting the above technical solution, when the seabed soil is relatively hard and the splice pile cannot be inserted into the mud and sand, the lifting component drives the rotating component and the reaming drill bit to extend out of the drive hole. The rotating component drives the reaming drill bit to rotate, thereby breaking the soil and allowing the splice pile to be inserted into the mud and sand, thus improving the stability of the platform body.

[0016] Optionally, the platform body has an adjustment groove on its side wall in the horizontal direction. An adjustment plate is slidably connected in the adjustment groove. A fourth hydraulic cylinder is installed in the adjustment groove. The piston rod of the fourth hydraulic cylinder is connected to the adjustment plate. The fourth hydraulic cylinder drives the adjustment plate to slide along the length of the adjustment groove. The lower pile pipe is located on the side of the adjustment plate away from the platform body. An adjustment component is provided on the surface of the adjustment plate. The lower pile pipe is connected to the adjustment component. The adjustment component drives the lower pile pipe to move in a direction away from or closer to the platform body.

[0017] By adopting the above technical solution, the fourth oil cylinder drives the adjusting plate to slide along the length of the adjusting groove, thereby effectively adjusting the orientation of the lower pile pipe, enabling the lower pile pipe to move laterally left and right. In coordination with the adjusting components, the lower pile pipe can be adjusted in more directions within the plane, increasing the range of pile lowering that the pile stabilizing platform of this application can perform, and has high flexibility and practicality.

[0018] Optionally, the adjustment assembly includes a center plate, two side plates, two adjustment motors, two adjustment screws, and two adjustment blocks, with each of the side plates, adjustment motors, adjustment screws, and adjustment blocks corresponding to the other. The center plate is vertically mounted on the side wall of the adjustment plate away from the platform body. The center plate includes a fixed part and a sliding part. The fixed part is connected to the adjustment plate, and the sliding part is located on the side of the fixed part away from the adjustment plate. The lower pile pipe is connected to the sliding part. The side wall of the sliding part is provided with a sliding plate, and the side wall of the fixed part has a sliding opening for sliding. A sliding groove for inserting and sliding the shift plate; two drive grooves are opened on the side wall of the adjustment plate corresponding to the side plate; the center plate is located between the two drive grooves; the adjustment motor is set in the corresponding drive groove; one end of the adjustment screw is connected to the output shaft of the adjustment motor, and the other end is rotatably connected to the inner wall of the drive groove; the adjustment block is threadedly connected to the peripheral wall of the corresponding adjustment screw; the side wall of the adjustment block abuts against the inner wall of the drive groove; the adjustment block extends out of the drive groove and is hinged to the corresponding side plate; the side wall of the side plate away from the adjustment block is hinged to the side wall of the lower pile pipe.

[0019] By adopting the above technical solution, the motor is started and the adjusting screw is rotated. Since the side wall of the adjusting block abuts against the inner wall of the drive groove, the adjusting block will drive the side plate to slide along the length of the drive groove under the action of the adjusting screw. When the side plates on both sides approach each other, since the side plates and the lower pile pipe are hinged, the side plates on both sides can push the lower pile pipe away from the adjusting plate. At this time, the sliding part and the fixed part will gradually separate, thereby adjusting the position of the pile. Conversely, when the side plates on both sides move away from each other, the lower pile pipe gradually moves closer to the platform body. The adjusting component of this application cooperates with the fourth oil cylinder to further expand the range of pile lowering of the pile stabilizing platform of this application, further improve the working efficiency, and improve the practicality and convenience of the pile stabilizing platform of this application.

[0020] Optionally, the lower pile pipe includes a first pipe, a second pipe, and a third pipe arranged from top to bottom. The first pipe and the third pipe are both connected to the sliding part and are hinged to the side plate. The sliding part has a separation groove on the side wall facing the second pipe. A rotating component is arranged in the separation groove. The output shaft of the rotating component is arranged in the vertical direction. A telescopic component is connected to the output shaft of the rotating component. The movable end of the telescopic component is connected to the side wall of the second pipe. Both side walls have clearance grooves through the corresponding separation grooves to allow the telescopic component to pass through.

[0021] By adopting the above technical solution, when multiple pipe piles need to be driven on the same side of the platform body, the rotating component can drive the second pipe to separate from the first and third pipes, and the telescopic component can flexibly adjust the position of the second pipe, so that during construction, piles can be driven through the first and second pipes at the same time, which further improves the construction efficiency of pile driving and the wide applicability of the pile stabilization platform of this application.

[0022] Optionally, both ends of the second pipe are provided with expansion grooves, and an electric telescopic rod is provided in the expansion groove. The movable end of the electric telescopic rod slides along the depth direction of the expansion groove. The movable end of the electric telescopic rod is connected to a plug-in piece. The end walls of the first pipe and the third pipe facing the second pipe are provided with positioning grooves for the plug-in piece to be inserted.

[0023] By adopting the above technical solution, when the second pipe does not need to be separated from the first and third pipes, the electric telescopic rod drives the plug-in piece to abut into the positioning groove, so that the second pipe can be connected with the first and third pipes, maintaining the consistency of movement, thereby improving the coaxiality and stability among the three, making the pipe pile driving more stable and smooth.

[0024] Optionally, the inner walls of the first, second, and third pipes are all provided with filling grooves in the circumferential direction, and an inflatable airbag is provided in the filling groove.

[0025] By adopting the above technical solution, an external fan can be used to inflate or deflate the airbag. When the airbag is inflated, it gradually expands, thereby changing the inner diameter of the pile tube that allows the pipe pile to pass through. This ensures that different types of tubular structures can fully contact the airbag during pile driving, guaranteeing the vertical driving of pipes of different diameters. This allows the pile stabilization platform of this application to adapt to the construction of pipe piles of different diameters, improving applicability and flexibility, and enhancing construction quality.

[0026] In summary, this application includes at least one of the following beneficial technical effects: The platform body is propelled by a vessel carrying pipe piles and positioned at the bottom of the vessel. Upon arrival at the construction site, the vessel lowers the platform body until it sinks to the bottom of the water. The first hydraulic cylinder drives the support piles to contact the seabed. After contact is completed, the second hydraulic cylinder drives the insertion piles to be inserted into the seabed sediment, thus positioning the platform body. Afterward, the pipe piles can be aligned with the lowering pipe to carry out the pile driving. After construction is completed, the platform body can be quickly recovered by simply using the second hydraulic cylinder to drive the insertion piles to detach from the seabed sediment. This saves the time of repeatedly building offshore operating platforms in existing technologies, reduces workload, shortens the construction cycle, and greatly improves the efficiency of offshore steel pipe construction. The stabilizing platform is made of lightweight materials. The buoyancy of seawater varies in different sea areas, which may prevent the stabilizing platform from sinking to the seabed. By setting up ballast water tanks and using ballast water to increase the self-weight of the platform body, the platform body can sink to the seabed. After the construction is completed, the ballast water is discharged, and the platform body can float to the surface, which further improves the construction efficiency and applicability of the stabilizing platform of this application. The platform's levelness is detected by the level detection module. After analysis by the control module, the appropriate balance propeller is selected and activated to counteract the force of the ocean current. By using different rotation speeds of the balance propellers at multiple locations, the platform can maintain its balance during descent, allowing subsequent pipe piles to be driven vertically. This method has high precision and practicality. The fourth hydraulic cylinder drives the adjusting plate to slide along the length of the adjusting groove, thereby effectively adjusting the orientation of the lower pile pipe, allowing the lower pile pipe to move laterally left and right. In conjunction with the adjusting components, the lower pile pipe can be adjusted in more directions within the plane, increasing the range of pile lowering that the pile stabilizing platform of this application can perform, and has high flexibility and practicality.

[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0036] This application discloses a pile stabilization platform that can be quickly positioned. (Refer to...) Figure 1 The system includes a platform body 1, which is located below the ship and is driven by the ship's winch mechanism to sink to the seabed. In this embodiment, the platform body 1 is square, and each of its four side edges is provided with a stabilizer 2 for stabilizing the platform body 1 on the seabed.

[0037] Reference Figure 1 and Figure 2 The stabilizer 2 includes a positioning tube 21, several first hydraulic cylinders 22, support piles 23, several second hydraulic cylinders 24, and plug-in piles 25. The positioning tube 21 is welded to the side edge of the platform body 1 and is vertically arranged. Several first hydraulic cylinders 22 are all connected to the inner wall of the end of the positioning tube 21 near the seabed. Several first hydraulic cylinders 22 are evenly distributed along the circumferential direction of the inner wall of the positioning tube 21. The support piles 23 are connected to the piston rods of the first hydraulic cylinders 22. The first hydraulic cylinders 22 can drive the support piles 23 to slide along the length direction of the positioning tube 21 until they come into contact with the seabed.

[0038] Reference Figure 2 and Figure 3The support pile 23 includes a movable part 231 and two abutting parts 232. The movable part 231 is connected to the piston rod of the first hydraulic cylinder 22 by welding. The side wall of the end of the movable part 231 extending out of the positioning tube 21 is provided with a clearance slope 234. The two abutting parts 232 are hinged to the clearance slope 234. The abutting parts 232 can rotate in a direction away from or close to the seabed. The surface of the clearance slope 234 is provided with two hidden holes 235 corresponding to the abutting parts 232. A third hydraulic cylinder 236 is provided in each hidden hole 235. The base of the third hydraulic cylinder 236 is hinged to the bottom wall of the hidden hole 235. The piston rod of the third hydraulic cylinder 236 is hinged to the side wall of the corresponding abutting part 232. The third hydraulic cylinder 236 can drive the abutting part 232 to rotate.

[0039] Reference Figure 3 and Figure 4 The platform body 1 is equipped with a control module 4. In this embodiment, the control module 4 can be a PLC controller. All third hydraulic cylinders 236 are controlled by the control module 4. Each contact part 232 has a pressure detection module 237 on its bottom wall. The pressure detection module 237 uses a pressure sensor and is electrically connected to the control module 4. The pressure detection module 237 is used to detect the pressure value on the bottom wall of the contact part 232 in real time and send it to the control module 4. The control module 4 has a preset pressure value (such as 10000N). If the actual detected pressure is... If the pressure value is less than the preset pressure value, it means that the abutment part 232 is not fully abutted. In this case, the control module 4 controls the corresponding third cylinder 236 to start, driving the abutment part 232 to rotate towards the seabed until it abuts the seabed. Conversely, if the actual pressure value is greater than the preset pressure value, it means that the abutment part 232 is over-abutting. In this case, the control module 4 controls the third cylinder 236 to start, driving the abutment part 232 to rotate away from the seabed, so that the abutment part 232 abuts the seabed, improving the tightness of the abutment between the support pile 23 and the seabed, and improving stability.

[0040] Reference Figure 2 and Figure 3Several second hydraulic cylinders 24 are positioned above the first hydraulic cylinder 22. These second hydraulic cylinders 24 are evenly distributed along the circumferential direction of the inner wall of the positioning tube 21. The insertion pile 25 is connected to the piston rod of the second hydraulic cylinder 24. A support pile 23 has a passage hole 233 through which the insertion pile 25 passes. The second hydraulic cylinder 24 drives the insertion pile 25 through the passage hole 233 and inserts it into the seabed sediment. A driving hole 251 is provided on the bottom wall of the insertion pile 25. The driving hole 251 contains a... There is a lifting component 252. The movable end of the lifting component 252 moves along the depth direction of the drive hole 251. The movable end of the lifting component 252 is connected to a rotating component 253. The output shaft of the rotating component 253 is connected to a reaming drill bit 254. In this embodiment, the lifting component 252 is a cylinder or a hydraulic cylinder, and the rotating component 253 is a waterproof motor. This allows the reaming drill bit 254 to expand the soil when the seabed mud and sand are relatively hard, thereby facilitating the insertion of the pile 25 and improving the stability of the platform body 1.

[0041] Reference Figure 1 , Figure 2 and Figure 4 The platform body 1 has four ballast water inlets 11 on each side wall, and the four ballast water inlets 11 are located at the corners of the side wall. Each ballast water inlet 11 is equipped with a filter screen 12. All ballast water inlets 11 are controlled by the control module 4. The platform body 1 has eight ballast water tanks 13 inside, and each ballast water tank 13 is connected to two of the ballast water inlets 11. The bottom wall of the platform body 1 is equipped with a buoyancy detection module 14 for detecting the buoyancy of the platform body 1. The buoyancy detection module 14 is electrically connected to the control module 4. In this embodiment, the buoyancy detection module 14 uses a buoyancy meter to detect the buoyancy of the platform body 1 in real time and send the buoyancy value to the control module 4. The control module 4 opens a corresponding number of ballast water inlets 11 based on the magnitude of the buoyancy value to introduce ballast water into the ballast water tanks 13 to balance the buoyancy of the platform body 1, so that the platform body 1 can overcome the buoyancy and sink to the seabed.

[0042] Reference Figure 2 and Figure 4Each side wall of the platform body 1 is equipped with four balancing propellers 15, which are located at the four corners of the side wall. All balancing propellers 15 are controlled by the control module 4. The top wall of the platform body 1 is equipped with a level detection module 16 for monitoring the levelness of the platform body 1. The level detection module 16 is electrically connected to the control module 4. In this embodiment, the level detection module 16 is a level instrument, which is used to monitor the levelness of the platform body 1 in real time and send the detection value to the control module 4. When the platform body 1 is affected by the ocean current and shifts in a certain direction, the control module 4 activates the corresponding balancing propeller 15 based on the detection value and adjusts the rotation speed of the corresponding balancing propeller 15 to counteract the force of the ocean current and balance the platform body 1, so that the platform body 1 can be set vertically and maintain the verticality of the subsequent pile driving.

[0043] Reference Figure 2 and Figure 5 Each side wall of the platform body 1 is provided with an adjustment groove 17 in the horizontal direction. An adjustment plate 18 is slidably connected in the adjustment groove 17. A fourth hydraulic cylinder 19 is provided in both ends of the adjustment groove 17. The piston rod of the fourth hydraulic cylinder 19 is connected to the adjustment plate 18 to drive the adjustment plate 18 to slide along the length of the adjustment groove 17. A pile lowering pipe 3 is provided on the side of each adjustment plate 18 away from the platform body 1. The pile lowering pipe 3 is set vertically and is used to drive the pipe pile. The adjustment plate 18 can drive the pile lowering pipe 3 to move left and right to adjust the orientation, so that the pile lowering pipe 3 can drive the pile lowering pipe 3 to ...

[0044] Reference Figure 1 and Figure 6 The adjustment plate 18 is provided with an adjustment component 5. The lower pile pipe 3 is connected to the adjustment component 5. The adjustment component 5 drives the lower pile pipe 3 to move away from or towards the platform body 1 for further orientation adjustment. The adjustment component 5 includes a center plate 51, two side plates 52, two adjustment motors 53, two adjustment screws 54 and two adjustment blocks 55. The side plates 52, adjustment motors 53, adjustment screws 54 and adjustment blocks 55 are arranged in a one-to-one correspondence.

[0045] Reference Figure 1 , Figure 5 and Figure 6The center plate 51 is vertically disposed on the side wall of the adjusting plate 18 away from the platform body 1. The center plate 51 includes a fixed part 511 and a sliding part 512. The fixed part 511 is connected to the adjusting plate 18 by welding. The sliding part 512 is disposed on the side of the fixed part 511 away from the adjusting plate 18. The lower pile pipe 3 is connected to the sliding part 512 by welding. Two sliding pieces 513 are welded to the side wall of the sliding part 512. The two sliding pieces 513 are distributed along the height direction of the sliding part 512. The side wall of the fixed part 511 is provided with a sliding groove 514 for the sliding pieces 513 to be inserted and slide. In this embodiment, the maximum sliding distance of the sliding part 512 is less than the length of the sliding piece 513.

[0046] Reference Figure 6 The side wall of the adjusting plate 18 has two drive grooves 181 corresponding to the side plate 52. The drive grooves 181 are horizontally opened, and the center plate 51 is located between the two drive grooves 181. The base of the adjusting motor 53 is welded into the corresponding drive groove 181. One end of the adjusting screw 54 is connected to the output shaft of the adjusting motor 53 through a coupling, and the other end is rotatably connected to the inner wall of the drive groove 181 through a bearing. The adjusting block 55 is sleeved on the periphery of the adjusting screw 54, and the adjusting block 55 and the adjusting screw 54 are threaded together. When the adjustment block 55 is closed, its side wall abuts against the inner wall of the drive groove 181. The adjustment block 55 extends out of the drive groove 181 and is hinged to the corresponding side plate 52. The side plate 52 is hinged to the side wall of the lower pile pipe 3 away from the adjustment block 55. When the two side plates 52 move toward each other, they will push the lower pile pipe 3 toward the direction away from the platform body 1. Conversely, when the two side plates 52 move away from each other, they will drive the lower pile pipe 3 toward the direction closer to the platform body 1, thereby flexibly adjusting the orientation of the lower pile pipe 3.

[0047] Reference Figure 6 and Figure 7 The lower pile pipe 3 includes a first pipe 31, a second pipe 32, and a third pipe 33 arranged from top to bottom. The first pipe 31 and the third pipe 33 are both welded to the sliding part 512 and hinged to the side plate 52. The end walls of both ends of the second pipe 32 are provided with expansion grooves 321. The depth direction of the expansion grooves 321 is consistent with the length direction of the second pipe 32. The expansion grooves 321 are opened along the circumferential direction of the second pipe 32. Several electric expansion rods 322 are provided in the expansion grooves 321. The movable end of the electric expansion rods 322 slides along the depth direction of the expansion grooves 321. The movable end of the electric expansion rods 322 is connected to a plug-in piece 323. The plug-in piece 323 is annular. The end walls of the first pipe 31 and the third pipe 33 facing the second pipe 32 are provided with positioning grooves 34 for the plug-in piece 323 to be inserted, so that the second pipe 32 can be stably connected to the first pipe 31 and the third pipe 33, thereby improving stability.

[0048] Reference Figure 5 and Figure 6 The sliding part 512 has a separation groove 515 on the side wall facing the second pipe 32. A rotating part 516 is provided in the separation groove 515. The output shaft of the rotating part 516 is arranged in the vertical direction. A telescopic part 517 is connected to the output shaft of the rotating part 516. The movable end of the telescopic part 517 is connected to the side wall of the second pipe 32. Both side walls are provided with clearance grooves 521 through the separation groove 515 to allow the telescopic part 517 to pass through. In this embodiment, the rotating part 516 is a motor and the telescopic part 517 is a cylinder or hydraulic cylinder. This allows the platform body 1 to adjust the position of the second pipe 32 without adjusting the platform body 1 when more pipe piles (such as 5 / 6 / 7 / 8 / 9 / 10 / 11 / 12 pipe piles) need to be driven. This improves convenience and flexibility.

[0049] Reference Figure 5 and Figure 7 The inner walls of the first pipe 31, the second pipe 32 and the third pipe 33 are all provided with filling grooves 35 in the circumferential direction. An inflatable airbag 36 is provided in the filling groove 35. When driving pipe piles of different diameters, the inflatable airbag 36 can abut against the outer wall of the pipe pile, thereby maintaining the verticality of the pipe pile, improving the accuracy of driving the pile and the applicability of the platform body 1 of this application.

[0050] The implementation principle of a rapidly positioning stabilizing platform according to an embodiment of this application is as follows: A vessel transports the platform body 1 to the sea area where construction is required. The platform body 1 is lowered by a winch mechanism on the vessel. During the lowering process, a ballast water system and a balance propeller 15 are used to lower the platform body 1, so that the platform body 1 can remain vertical. After the platform body 1 is lowered to the seabed, it is stabilized by a stabilizer 2. The support pile 23 is abutted against the seabed, and the insertion pile 25 is inserted into the mud and sand on the seabed. Subsequently, the orientation of the pile pipe 3 is adjusted by adjusting the adjustment component 5 and the fourth hydraulic cylinder 19 according to the required pile position to realize the construction of offshore steel pipe piles. After the construction is completed, the platform body 1 can be quickly recovered simply by releasing the stabilizer 2.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
