The existing deep water pile stabilizing platform is mainly of a truss type, and different pile stabilizing platforms corresponding to different water depths are needed, and several pile stabilizing platforms of different specifications are needed for a wind farm with a large water depth coverage, which leads to a large resource occupation. The planar position accuracy of an offshore wind turbine foundation is relatively high, generally 300-500mm, but it is difficult to control the accuracy after the pile stabilizing platform is positioned in the sea by a floating crane, which makes it difficult to control the final position of the steel pipe pile. Moreover, the truss has a tendency to tilt forward due to the heavy clamp on the front side of the truss, which makes it difficult to keep the clamp at a horizontal angle, causing certain difficulties in leveling. Therefore, the above problems need to be solved. SUMMARY

Then, freely choose to combine the elevating frame and the main frame according to different water depths to assemble a single pile stabilizing platform or a four pile stabilizing platform. Place the single pile stabilizing platform or the four pile stabilizing platform vertically on the outboard platform of the crane vessel.

[0017] Step 3: The crane on the crane ship places the anti-sinking plate of the monopile stabilizing platform or the four-pile stabilizing platform on the seabed, then lifts the vibratory hammer, and positions and stabilizes the monopile stabilizing platform or the four-pile stabilizing platform through four positioning piles.

Detailed Implementation

[0053] The technical solution of the present invention will be clearly and completely described below through specific embodiments.

[0054] This invention discloses a steel pipe pile construction system based on a modular pile stabilization platform, comprising a crane vessel 11, a top frame I1, a top frame II2, a heightening frame 3, a main frame 4, an anti-sinking plate 5, a first pile gripper 9, a first adjustment mechanism 6, a second pile gripper 10, a second adjustment mechanism 7, and a guide pipe 8; the specific structure is as follows: Figures 1-13As shown, the top frame I1, top frame II2, elevated frame 3, and main frame 4 are all truss structures welded and spliced ​​together from four vertical main guide pipes, several inclined reinforcing pipes, and several horizontal reinforcing pipes, and their horizontal sections are matched respectively. The height of elevated frame 3 is less than the height of main frame 4, and the inner diameter of the main guide pipes of top frame I1, top frame II2, elevated frame 3, main frame 4, and anti-sinking plate 5 are all matched with the positioning pile 14. On the upper surface of the corresponding main guide pipes of elevated frame 3, main frame 4, and anti-sinking plate 5, upper flanges 41 are respectively provided in a rectangular horizontal symmetrical manner. Furthermore, the lower surface of the corresponding main pipe of the main frame 4 is also provided with a rectangular horizontally symmetrical lower flange 42 that matches the upper flange 41; each upper flange 41 and lower flange 42 is a ring-shaped structure that matches the positioning pile 14, and its setting position corresponds to the insertion position of the corresponding positioning pile 14. Thus, through the screw connection of the upper flange 41 and the corresponding lower flange 42, the top frame I1, the heightening frame 3, the main frame 4 and the anti-sinking plate 5 can be screwed together to form a single pile stabilizing platform, or the top frame II2, the heightening frame 3, the main frame 4 and the anti-sinking plate 5 can be screwed together to form a four pile stabilizing platform.

[0055] In this invention, several first stiffening plates 43 are vertically and evenly distributed along the circumference of each upper flange 41 between its lower surface and the corresponding main guide pipe of the corresponding heightening frame 3, main frame 4, and anti-sinking plate 5, and the corresponding upper flange 41 is reinforced and fixed by the stiffening plates; for example Figure 7 , Figure 8 As shown, several second stiffening plates 47 are evenly distributed vertically along the circumference between the upper surface of each lower flange 42 and the corresponding main pipes of the corresponding top frame I1, top frame II2, elevating frame 3, and main frame 4, and the corresponding lower flange 42 is reinforced and fixed by the second stiffening plates 47; several limiting plates 44 are evenly distributed vertically along the circumference of the upper surface of each upper flange 41, each limiting plate 44 is set vertically along the radial direction of the corresponding upper flange 41, and all the limiting plates 44 on the same upper flange 41 form a circular area that matches the outer diameter of the corresponding lower flange 42, thereby positioning the lower flange 42 when it is connected to the corresponding upper flange 41 by the limiting plates 44; each upper flange 41 and each lower flange 42 are coaxially arranged with the corresponding positioning pile 14, and the positioning pile 14 passes through the corresponding upper flange 41 plate and lower flange 42 plate from top to bottom, thereby positioning the single pile stabilizing platform or the four pile stabilizing platform.

[0056] The present invention also provides two first pile grippers 9 for positioning the steel pipe piles 15 by horizontal symmetry at vertical intervals on one outer side of the top frame I1, as shown below. Figures 1-13As shown, each first pile gripper 9 is connected to the top frame I1 via a first adjustment mechanism 6, and its posture is corrected by the first adjustment mechanism 6. At the four right angles on the outer side of the top frame II2, second pile grippers 10 are horizontally symmetrically arranged for positioning the steel pipe piles 15. Furthermore, guide cylinders are vertically and coaxially arranged on the outer side of the main frame 4, directly below the second pile grippers 10. Each guide cylinder is screwed to the main frame 4 via a second adjustment mechanism 7, and its posture is corrected by the second adjustment mechanism 7. This invention selects either the top frame I1 or the top frame II2 according to the needs of single or four pile applications. Then, depending on the water depth, the raising frame 3 and the main frame 4 are freely selected for combination, thereby assembling a single-pile stabilizing platform or a four-pile stabilizing platform. Then, through the cooperation of the crane 12 and vibratory hammer 13 on the crane vessel 11, the single-pile stabilizing platform or the four-pile stabilizing platform is first positioned, and then the steel pipe pile 15 is driven.

[0057] A hollow area for installing the second adjustment mechanism 7 is provided at the center of the main frame 4 relative to the guide tube 8, and fixing plates 45 are respectively attached and fixed to the inner side of the corresponding main guide tube of the main frame 4 at the installation position of the guide tube 8; Figure 7 , Figure 9 , Figure 12 , Figure 13 As shown, a connecting block 81 is vertically provided on the outer circumferential surface of each guide tube 8 at a position slightly above the main frame 4, and a hinge frame 82 is vertically provided on the outer circumferential surface of each guide tube 8 at a position slightly below the main frame 4. A connecting seat 46 is also vertically provided on the outer side of the main frame 4 at the position of the hinge frame 82 corresponding to the guide tube 8. Each second adjustment mechanism 7 is supported on the bottom horizontal reinforcing tube of the hollow area of ​​the main frame 4, and its fixed end is screwed to the corresponding fixed plate 45 of the main frame 4. The adjustment end of each second adjustment mechanism 7 extends horizontally out of the main frame 4 and is screwed to the connecting block 81 of the corresponding guide tube 8. The hinge frame 82 of each guide tube 8 is vertically hinged to the corresponding connecting seat 46 of the main frame 4, thereby correcting the posture of the corresponding guide tube 8 through the second adjustment mechanism 7.

[0058] Each of the second adjusting mechanisms 7 in this invention includes a fixed frame 701, a fourth hydraulic cylinder 707, a fifth hydraulic cylinder 709, a first connecting flange 705, a third connecting flange 702, a cylinder base 706, a cylinder 708, a first reinforcing plate 711, a second connecting flange 710, a first connecting piece 713, a telescopic rod 712, a second connecting piece 714, a second reinforcing plate 704, and a third reinforcing plate 703; as shown Figures 11-13As shown, each fixing frame 701 is a cuboid truss structure, and each is matched with the installation position in the hollow area inside the main frame 4. On one side of each fixing frame 701, at a position relative to the fixing plate 45, a third connecting flange 702 matching the fixing plate 45 is vertically fixed, and each third connecting flange 702 is fixedly connected to the corresponding position of the corresponding fixing frame 701. Each fixing frame 701 is installed in the hollow area inside the main frame 4, and is screwed to the corresponding fixing plate 45 of the main frame 4 via the third connecting flange 702, and supported on the horizontal reinforcing tube of the bottom plate 605 in the central area of ​​the main frame 4. A fourth hydraulic cylinder 707 is horizontally installed on the upper surface of each fixing frame 701 away from the guide tube 8, and each fourth hydraulic cylinder 707 is horizontally fixed to the corresponding fixing frame. On 701, its movable ends are respectively set towards the center of the corresponding guide tube 8, and a fifth hydraulic cylinder 709 is also coaxially and horizontally linked at its movable end. Under the push of the corresponding fourth hydraulic cylinder 707, each fifth hydraulic cylinder 709 performs horizontal reciprocating motion along the radial direction of the guide tube 8 on the upper surface of the corresponding fixed frame 701, and its movable end extends out of the main frame 4 towards the center of the guide tube 8, and is screwed to the connecting block 81 of the corresponding guide tube 8 through the first connecting flange 705. Each guide tube 8 is vertically hinged to the corresponding connecting seat 46 of the main frame 4 through the hinge frame 82. Then, under the drive of the fifth hydraulic cylinder 709, the guide tube 8 rotates vertically around the corresponding connecting seat 46 of the main frame 4 to correct the posture of the guide tube 8 and ensure that the main frame 4 does not interfere with the adjustment action of the second adjustment mechanism 7.

A cylinder 708 is coaxially sleeved and slidably mounted on each fifth hydraulic cylinder 709, and the interior of each cylinder 708 matches the cylinder body of the corresponding fifth hydraulic cylinder 709 and the movable end of the corresponding fourth hydraulic cylinder 707, thereby allowing each fifth hydraulic cylinder 709 to reciprocate horizontally along the guide tube 8 within the corresponding cylinder 708. One end of each cylinder 708 near the corresponding guide tube 8 extends horizontally and vertically out of the corresponding fixed frame 701, and is respectively connected to the corresponding fixed frame 701.

[0060] like Figures 11-13As shown, the length of each cylinder 708 is less than the cylinder length of the corresponding fifth hydraulic cylinder 709. A telescopic rod 712 is vertically inclined on the side of the fifth hydraulic cylinder 709 extending beyond the center of the corresponding cylinder 708, near the center of the fixing frame 701. The tail of each telescopic rod 712 is vertically hinged to the corresponding side of the fixing frame 701 at the middle position via a first connecting member 713. The telescopic ends are inclined towards the corresponding fifth hydraulic cylinder 709 and vertically hinged to the corresponding position of the cylinder body of the fifth hydraulic cylinder 709 via second connecting members 714. Each second connecting member 714 is fixedly installed at the corresponding position of the portion of the cylinder body of the fifth hydraulic cylinder 709 extending beyond the corresponding cylinder 708. Each of the first connecting rods 712 is positioned so as not to interfere with the corresponding cylinder 708. Under the drive of the fifth hydraulic cylinder 709, each telescopic rod 712 rotates vertically, thereby supporting and reinforcing the corresponding fifth hydraulic cylinder 709. Each first connecting rod 713 is fixedly connected to the corresponding side of the fixed frame 701, and a second reinforcing plate 704 is vertically provided between its lower surface and the fixed frame 701, and the second reinforcing plate 704 supports and reinforces the corresponding first connecting rod 713.

[0061] The first adjustment mechanism 6 of this invention does not interfere with the insertion action of the positioning pile 14, and includes a first frame plate 601, a second frame plate 602, a first rotating shaft 603, a base 604, a first hydraulic cylinder 608, a jacking block 609, a base plate 605, a second rotating shaft 606, a second hydraulic cylinder, a moving plate 611, a connecting plate 612, a third hydraulic cylinder, and rollers 607; Figures 1-4As shown, two first frame plates 601 are horizontally spaced at intervals on the upper surface of the top frame I1, and two second frame plates 602 are horizontally spaced at intervals between the two first frame plates 601. The height of each first frame plate 601 is greater than the height of the corresponding second frame plate 602, and the left ends of the two first frame plates 601 extend horizontally and vertically to form a second frame plate 602 on the left side, which is then spliced ​​together to form a horizontally set first support. Bases 604 are respectively provided on the outer left ends of the two first frame plates 601. Each base 604 is vertically fixed to a corresponding position on the upper surface of the top frame I1, and a first rotating shaft 603 passes horizontally and vertically through the two bases 604 and the two first frame plates 601, thereby allowing the first support to be vertically rotatably connected to the corresponding base 604. The right end of the frame is also provided with a first hydraulic cylinder 608 in a horizontal and longitudinal direction. Each first hydraulic cylinder 608 is fixed at a corresponding position on the upper surface of the top frame I1, and its piston rod extends horizontally toward the corresponding first frame plate 601 and is screwed to the corresponding push block 609. Each push block 609 is a right-angled triangular structure, and its inclined surface is set toward the corresponding first frame plate 601. A triangular groove matching the push block 609 is also embedded on the outer side of each first frame plate 601 at the position relative to the push block 609. Then, through the cooperation of the push block 609 and the triangular groove, under the drive of the first hydraulic cylinder 608, the first bracket rotates vertically around the base 604, thereby driving the first pile gripper 9 to rotate vertically and perform a posture correction on the first pile gripper 9.

Each roller 607 is coaxially aligned with the second rotating shaft 606 and is independently connected to the second hydraulic cylinder 610. Each roller 607 is conical, with a smaller end near the second rotating shaft 606 and a larger end, to accommodate a lower linear velocity near the second rotating shaft 606 when the base plate 605 rotates, thereby ensuring the stability of the horizontal rotation of the base plate 605.

[0063] like Figures 1-4 As shown, a movable plate 611 is horizontally and laterally slidably connected to the upper surface of the base plate 605, and the right end of the movable plate 611 is connected to the fixed end of the horizontally set first pile gripper 9. Connecting plates 612 are horizontally fixed on both the front and rear sides of the middle position of the base plate 605, and a third hydraulic cylinder 613 is horizontally and laterally arranged on the side of each connecting plate 612 near the first pile gripper 9. The tail of each third hydraulic cylinder 613 is fixedly connected to the upper surface of the base plate 605, and its piston rod is screwed to the corresponding connecting plate 612, thereby pushing the movable plate 611 to move horizontally and laterally, and performing the third posture correction of the first pile gripper 9.

[0064] The construction process of a steel pipe pile construction system based on a modular pile stabilization platform, as described in this invention, is innovative in that it includes the following steps:

[0065] Step 1: First, the crane vessel 11 transports the top frame I1, top frame II2, heightening frame 3, main frame 4, anti-sinking plate 5, first adjustment mechanism 6, first pile gripper 9, second pile gripper 10, second adjustment mechanism 7, and guide pipe 8 to the site.

[0066] Step 2: Select either top frame I1 or top frame II2 according to the usage requirements of single pile and four pile, and then freely select the heightening frame 3 and main frame 4 according to different water depths to combine them, thereby assembling a single pile stabilizing platform or a four pile stabilizing platform, and placing the single pile stabilizing platform or the four pile stabilizing platform vertically on the outer platform 16 of the crane vessel 11.

[0067] In the above steps, if a single pile is required, the first pile gripper 9 is first connected to the top frame I1 through the first adjusting mechanism 6. Then, through the cooperation of the upper flange 41 and the lower flange 42, the top frame I1, the elevating frame 3, the main frame 4, and the anti-sinking plate 5 are screwed together to form a single pile stabilizing platform. If four piles are required, the second pile gripper 10 is first connected to the top frame II2. The guide pipe 8 is connected to the main frame 4 through the second adjusting mechanism 7. Then, through the cooperation of the upper flange 41 and the lower flange 42, the top frame II2, the elevating frame 3, the main frame 4, and the anti-sinking plate 5 are screwed together to form a four pile stabilizing platform.

[0068] Step 3: The crane 12 on the crane vessel 11 places the anti-sinking plate 5 of the single-pile stabilizing platform or the four-pile stabilizing platform on the seabed, then lifts the vibratory hammer 13, and uses four positioning piles 14 to position and stabilize the single-pile stabilizing platform or the four-pile stabilizing platform.

[0069] Step 4: Then, the crane 12 on the crane ship 11 lifts the vibratory hammer 13 to press and drive the steel pipe pile 15. During this process, the first pile gripper 9 is triple-positioned through the first adjustment mechanism 6, or the guide tube 8 is positioned through the second adjustment mechanism 7, so as to ensure the guidance and positioning of the steel pipe pile 15.

[0070] Step 5: After the steel pipe piles 15 are driven into the ground, the vibratory hammer 13 is retrieved by the crane 12 of the crane vessel 11, and then the single pile stabilizing platform or the four pile stabilizing platform is retrieved. Then the crane vessel 11 leaves the site.

[0071] The beneficial effects of this invention are:

[0072] (1) The present invention uses the upper flange 41 plate and the lower flange 42 plate together to adjust the truss height according to different water depths, and can also be combined and replaced according to the use requirements of single pile and four piles, which saves time and effort, saves costs, and has a wide range of applications.

[0073] (2) By setting the first adjustment mechanism 6, the first pile holder 9 has the ability to correct posture, which can compensate for the horizontal deviation caused by the positioning of the single pile stabilizing platform, and can also compensate for the tilt angle deviation of the single pile stabilizing platform, thereby improving construction efficiency and construction quality.

[0074] (3) By setting the second adjustment mechanism 7, the present invention enables the guide tube 8 to have posture correction capability, which can compensate for the horizontal deviation caused by the positioning of the four-pile stabilizing platform, and can also compensate for the tilt angle deviation of the four-pile stabilizing platform, thereby improving construction efficiency and construction quality.

[0075] (4) By setting a limiting plate 44, the present invention plays a limiting role in the process of combined screw connection, thereby improving the screw connection fixing accuracy and construction efficiency.
