Description

Technical Field

[0001] This invention relates to the field of offshore wind power foundation construction technology, and more specifically, to an offshore wind power foundation construction organization. Background Technology

[0002] Offshore wind turbine foundation solidification technology essentially transforms unreliable natural soft foundations into solid and reliable artificial foundations through "soil modification," thereby providing a more stable "foothold" for the wind turbine. In the prior art, for example, the document with application number CN202311657063.X, the prior art uses the circular motion of a ship around the pile foundation to drive the horizontal arm to move around the pile foundation; during the movement of the horizontal arm around the pile foundation, the moving unloading vehicle moves along the horizontal arm, causing the bracket to drive the limiting net to move outward in a spiral shape, and the limiting net is spirally arranged on the seabed around the pile foundation to form an anti-scouring spiral; although it can complete the solidification of the pile foundation root, it has the following defects; Since the surrounding vessel, cross arm, bracket, and discharge pipe need to make continuous circular motion during operation, and because of their large size, they generate significant convection in the surrounding water, especially causing significant disturbance to the solidified soil slurry and affecting its solidification, it is necessary to design a pile filling mechanism that avoids causing significant disturbance to the water.

Detailed Implementation

[0016] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] This application provides a construction organization for offshore wind power foundations. Please refer to [the relevant documentation / reference]. Figures 1-6 The structure includes: 1. Solidified soil slurry; 2. Foundation piles; 3. Foundation pit; 4. Sea surface; 5. Seabed; and 6. Winch 6 is installed on the upper end of foundation piles 2. The structure also includes: Positioning ring 7 and positioning wheel 8: Positioning ring 7 is fitted on foundation pile 2 and is coaxial with foundation pile 2; Positioning ring 7 is slidably connected to foundation pile 2 through positioning wheel 8; Positioning wheel 8 moves in the radial direction of positioning ring 7 to adapt to foundation piles 2 of different diameters. The dispersion box 9 and the main pipeline 10 are connected to the dispersion box 9. Multiple main pipelines 10 are provided and arranged in a ring. The main pipeline 10 is hinged to the dispersion box 9 and swings along the hinge point. The drive assembly 11 and the secondary pipe 12 are located on the side wall of the main pipe 10 and are connected to the main pipe 10. The drive assembly 11 drives the secondary pipe 12 to swing synchronously. The solidified soil slurry 1 is discharged through multiple main pipes 10 and secondary pipes 12, and the solidified soil slurry 1 covers a circular area. The reinforcing mesh 13 swings in a Z-shape as it adheres to the foundation pit 3 along with the solidified soil slurry 1.

[0018] In practical applications, the solidified soil slurry 1 is transported to the construction site by a transport ship. The winch 6 and the transport ship are existing technologies and will not be described in detail. After the foundation pile 2 and the foundation pit 3 reach the predetermined target, the solidified soil slurry 1 can be filled. First, the positioning ring 7 and positioning wheel 8 are put on the foundation pile 2 and fixed with external supports to prevent them from falling. Then, a pair of winches 6 are symmetrically fixed on the foundation pile 2, and the traction end of the winch 6 is fixedly connected to the positioning ring 7. At this time, the operation of the winch 6 can pull the positioning ring 7 up or down. Finally, the main pipe 10, the auxiliary pipe 12 and the drive assembly 11 are installed. A connecting channel is provided between the dispersion box 9 and the transport ship. The transport ship is equipped with equipment for actively conveying solidified soil slurry 1. The winch 6 is controlled to extend its traction end, and the positioning ring 7, main pipe 10 and auxiliary pipe 12 are in the lowest position. At this time, the main pipe 10 and auxiliary pipe 12 are in a retracted state, and the openings of the main pipe 10 and auxiliary pipe 12 face the root of the foundation pile 2. At this time, the solidified soil slurry 1 enters the main pipe 10 and auxiliary pipe 12 through the first hose 92, the dispersion box 9 and the second hose 93, and is finally discharged through the main pipe 10 and auxiliary pipe 12. At the same time, the main pipe 10 is slowly oscillating, the angle between the main pipe 10 and the foundation pile 2 gradually increases, the angle between the secondary pipe 12 and the main pipe 10 also gradually increases, and the discharge range of the solidified soil slurry 1 gradually increases. Through the setting of multiple secondary pipes 12 and main pipes 10, the secondary pipes 12 and main pipes 10 can discharge the solidified soil slurry 1 around the foundation pile 2 in one oscillation, and the solidified soil slurry 1 will fill the surrounding circular area. Afterwards, the main pipe 10 and the secondary pipe 12 shrink, and a second filling is carried out. Repeating the above operation can fill the foundation pit 3. In the above filling process, in order to improve the structural strength of the solidified soil slurry 1 after solidification, the reinforcing mesh 13 can be added to the filling work of the solidified soil slurry 1, so as to cover the solidified soil slurry 1 and strengthen the strength of the solidified soil slurry 1.

[0019] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The positioning ring 7 is a hollow structure. The traction end of the winch 6 is fixedly connected to the positioning ring 7. A rectangular tube 71 is installed on the inner wall of the positioning ring 7. A telescopic rod 72 is installed inside the rectangular tube 71. The telescopic rod 72 and the rectangular tube 71 have rectangular cross-sections. The positioning wheel 8 is installed at one end of the telescopic rod 72. A bearing 73 is installed on the positioning ring 7. A rotating shaft 74 is installed on the inner ring of the bearing 73. A bevel gear 75 is installed at one end of the rotating shaft 74. The other end of the rotating shaft 74 is provided with an external thread 76. A threaded hole 77 that meshes with the external thread 76 is opened on the rectangular tube 71. A bearing 78 is installed on the inner side of the positioning ring 7. A support ring 79 is installed on the outer ring of the bearing 78. A gear ring 791 that meshes with the bevel gear 75 is installed on the outer side of the support ring 79. A driver 792 is installed on the inner side of the positioning ring 7. A gear set 793 is installed on the rotating end of the driver 792. The driver 792 is connected to the gear ring 791 through the gear set 793.

[0020] In practical applications, during operation, the positioning wheel 8 is in close contact with the foundation pile 2. In order to accommodate foundation piles 2 of different diameters, the positioning wheel 8 is in a retractable state. The driver 792 rotates forward, which drives the support ring 79 and gear ring 791 to rotate through the transmission of the gear set 793. The gear ring 791 drives four pairs of bevel gears 75 to rotate, and the bevel gears 75 drive the rotating shaft 74 and the external thread 76 to rotate. The rotating shaft 74 rotates stably through the action of bearing 73, and the support ring 79 rotates stably through the action of bearing 78. The rotating shaft 74 drives the positioning wheel 8 and the telescopic rod 72 to extend out of the rectangular tube 7 through the threaded hole 77 and the external thread 76. This is suitable for foundation piles 2 with small diameters. When the control driver 792 reverses, the positioning wheel 8 and the telescopic rod 72 retract into the rectangular tube 7, at which point a large-diameter foundation pile 2 is applicable.

[0021] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4One end of the telescopic rod 72 is equipped with a sealing sleeve 721. One end of the sealing sleeve 721 is fixedly connected to the telescopic rod 72, and the other end of the sealing sleeve 721 is fixedly connected to the positioning ring 7. There are four pairs of rectangular tubes 71, which are evenly distributed on the four quadrant points of the positioning ring 7. Each pair of rectangular tubes 71 has two tubes and they are arranged in the vertical direction.

[0022] In practical applications, the sealing sleeve 721 prevents seawater from flowing into the positioning ring 7 through the position of the telescopic rod 72. The rectangular tube 71 has four pairs of positioning wheels, and four pairs of positioning wheels 8 are also provided to make the positioning ring 7 move up and down stably.

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The dispersion box 9 is installed below the positioning ring 7. The dispersion box 9 has an annular cavity 91 inside. The upper end of the dispersion box 9 is provided with a first hose 92, and the lower end of the dispersion box 9 is provided with a second hose 93. There are multiple second hoses 93 arranged in a ring. An input pipe 94 is installed on the first hose 92. The main pipeline 10 is connected to the dispersion box 9 through the second hose 93. The lower end of the dispersion box 9 is provided with a hinge rod 95, which is hinged to the main pipeline 10. The main pipeline 10 swings along the hinge point. A hydraulic rod 96 is installed between the hinge rod 95 and the main pipeline 10.

[0024] In practical applications, the input pipe 94 and hose 92 are used to connect the transport ship. The dispersion box 9 delivers the solidified soil slurry 1 into multiple hoses 93. The main pipe 10 is supported by the hinge rod 95. The main pipe 10 rotates along the hinge point of the hinge rod 95. The specific angle of the main pipe 10 can be controlled by the extension and retraction of the hydraulic rod 96.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The cross-section of the annular cavity 91 is trapezoidal, with the acute angle of the trapezoid facing downwards.

[0026] In practical applications, the trapezoidal acute angle is positioned downwards to facilitate the flow of the solidified soil slurry 1 to the second hose 9, thus preventing the solidified soil slurry 1 from remaining in the annular cavity 91.

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5The drive assembly 11 includes a sliding ring 111, which is mounted on the main pipe 10. A hydraulic rod 112 is installed between the sliding ring 111 and the main pipe 10. A flexible pipe 113 is installed on the lower side wall of the main pipe 10. Multiple flexible pipes 113 are provided. A secondary pipe 12 is connected to the main pipe 10 through the flexible pipe 113. A fixed rod 114 is installed at the lower end of the main pipe 10. The two sides of the secondary pipe 12 are hinged to the fixed rod 114. A connecting rod 115 is installed between the secondary pipe 12 and the sliding ring 111.

[0028] In practical applications, the extension and retraction of hydraulic rod 112 can drive sliding ring 111 to slide on main pipe 10. When sliding ring 111 slides upward, it pulls secondary pipe 12 upward through connecting rod 115, which can increase the discharge area of ​​solidified soil slurry 1. When sliding ring 111 slides downward, it can reduce the discharge area of ​​solidified soil slurry 1.

[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 A mesh basket 101 is installed on the side wall of the main pipe 10. A main shaft 102 is located at the center of the mesh basket 101. An opening 103 is located below the mesh basket 101. A reinforcing mesh 13 is wound around the main shaft 102. The reinforcing mesh 13 can extend and retract through the opening 103. One end of the reinforcing mesh 13 is connected to the main shaft 102. An electrically controlled clamp 104 is installed on one side of the lower end of the secondary pipe 12. The other end of the reinforcing mesh 13 is connected to the electrically controlled clamp 104.

[0030] In practical applications, to enhance the strength of the solidified soil slurry 1, the reinforcing net 13 is actively released when filling the solidified soil slurry 1. Initially, one end of the reinforcing net 13 needs to be manually fixed to the electrically controlled clamp 104. At this time, the reinforcing net 13 covers the main pipe 10 and the secondary pipe 12. As the solidified soil slurry 1 is discharged, the reinforcing net 13 is gradually released, and the solidified soil slurry 1 presses the reinforcing net 13 into the foundation pit 3. As the main pipe 10 and the secondary pipe 12 swing back and forth, the reinforcing net 13 is stacked in a Z-shape in the foundation pit 3. After the first filling, the control electric clamp 104 releases the reinforcing net 13.

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 Electrically controlled valves 121 are installed on the main pipe 10 and the secondary pipe 12.

[0032] In practical applications, the flow rate of the solidified soil slurry 1 at the corresponding location can be controlled by setting the electrically controlled valve 121.

[0033] Reference Figure 1 , Figure 2 , Figure 3and Figure 6 The positioning ring 7 is divided into a left ring 701 and a right ring 702. The left ring 701 and the right ring 702 are in a connected state. A flange 703 is installed on each of the left ring 701 and the right ring 702. A connecting bolt 704 is installed on the flange 703.

[0034] In practical applications, the positioning ring 7 can be divided into two parts by setting the left ring 701 and the right ring 702. Although it needs to be connected later by connecting bolts 704, it has good flexibility in transportation.

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A lifting ring 705 is installed on the positioning ring 7, and the traction end of the winch 6 is connected to the lifting ring 705.

[0036] In practical applications, the lifting ring 705 facilitates the connection between the traction end of the winch 6 and the positioning ring 7.
