Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind power pile foundation construction, and in particular to a construction device and a construction method for an offshore wind power pile foundation anti-scour solidified soil pile foundation. Background Art

[0002] The anti-scouring solidified soil pile foundation construction device for offshore wind power pile foundation plays an important role in offshore wind power projects. It aims to effectively prevent the scouring of the seabed around the pile foundation through solidified soil technology, and ensure the stability and safety of wind power facilities.

[0003] After searching, the Chinese patent with publication number CN118257263A discloses an offshore wind power pile foundation anti-scour solidification soil construction device and construction method, which includes a flow rate measuring device, a moisture meter, a host computer, a feeding device, and a curing agent pre-mixing device, a mud stirring device and a pumping and blowing filling device connected in sequence; the feeding device conveys the curing agent and water to the curing agent pre-mixing device, and conveys the soil and water to the mud stirring device; the host computer calculates the ratio of curing agent to water and the ratio of soil to water according to the soil moisture content and water flow rate, and controls the conveying amount of curing agent, soil and water in the feeding device; the curing agent pre-mixing device stirs the curing agent and water to obtain a mixed liquid; the mud stirring device stirs the water and soil to obtain an initial mud, and then stirs the mixed liquid and the initial mud to obtain mud; the pumping and blowing filling device pumps the mud to the construction site. The above scheme not only achieves a better stirring effect, but also can accurately control the proportion of materials. However, the above scheme still has the following shortcomings when used in practice:

[0004] The above solution uses the excavator bucket to mix water, curing agent and soil. Since the bucket was not originally designed for mixing operations, its mixing space is limited, making it difficult to ensure that the water, curing agent and soil are fully and evenly mixed throughout the mixing process. This insufficient mixing may lead to unstable quality of the cured soil, which in turn affects the scour resistance of the offshore wind turbine pile foundation and increases project risks and maintenance costs.

The two fixed frames are respectively fixed on the sides of the two baffles. Each of the fixed frames is a U-shaped structure, and the two ends of the rotating rod are respectively located in the two fixed frames.

The rotating shaft will only rotate when the operator controls the bucket to press down the connecting rod. This design improves the reliability of the mixing operation and helps to accurately control the flow direction and mixing effect of the mud, thereby improving the efficiency and quality of the entire mud solidification process.

[0031] 3. The gear and two racks are arranged inside the partition box, which provides a relatively sealed space for them to block the contact between the mud and the components. On the one hand, it avoids the corrosion and wear of the components by impurities, chemicals and moisture in the mud, extends the service life of the components and reduces the maintenance cost of the equipment. On the other hand, it prevents the viscosity of the mud and particulate matter from adhering to and accumulating on the surface of the components, ensuring that the gear and rack can mesh and transmit smoothly and accurately, ensuring the accuracy and reliability of the mixing operation, and ensuring the stability and accuracy of the entire mixing system.

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0042] Reference Figure 1-8 , a construction device for offshore wind power pile foundation anti-scour solidified soil pile foundation, including a curing box 1, two first guide rods 2 are fixed inside the curing box 1, and the two first guide rods 2 are arranged at the inner top position of the curing box 1. A sliding assembly is provided inside the curing box 1, and the sliding assembly includes a sliding plate 31, and the sliding plate 31 has two guide openings 32. The two first guide rods 2 pass through the two guide openings 32 respectively. The sliding plate 31 has two openings 33, and the two openings 33 are arranged in an upper and lower direction. A top rod 34 is fixed to the top of the sliding plate 31, and the top rod 34 extends to the outside of the curing box 1 at one end away from the sliding plate 31.

[0043] When the anti-scour solidified soil pile foundation construction device for offshore wind power pile foundation proposed by the present invention is in use, the staff puts water, silt and curing agent into the curing box 1, so that the curing agent solidifies the silt. After the curing is completed, the mixed solidified soil is transported to the underwater pile foundation position using a delivery pump and a delivery pipe. The grouting module continues to work during this process to ensure that the solidified soil can fit tightly to the covering soil layer around the pile. After the solidified soil solidifies around the pile foundation, it forms a solid protective layer that effectively resists the scouring of seawater.

[0044] A shielding assembly is provided on the sliding plate 31, which consists of two shielding structures. The two shielding structures are used to shield the two openings 33 respectively. The shielding structure includes a baffle 41, two second guide rods 42 and two guide blocks 43. The two second guide rods 42 are fixed to the side of the sliding plate 31. Each second guide rod 42 has a U-shaped structure. The two guide blocks 43 are respectively fixed to the upper and lower ends of the baffle 41. The two guide blocks 43 are respectively slidably mounted on the two second guide rods 42. The side of the baffle 41 is in contact with the side of the sliding plate 31, and the moving path of the baffle 41 completely covers the corresponding opening 33.

[0045] A rotating assembly is provided on the sliding plate 31, and the rotating assembly is used to control the operation of the two shielding structures. The rotating assembly includes a rotating shaft 51, a rotating rod 52 and two fixed frames 53. The rotating shaft 51 is rotatably installed in the middle position of the side of the sliding plate 31. The end of the rotating shaft 51 away from the sliding plate 31 passes through the first hole and extends to the inside of the partition box 81. The rotating rod 52 is fixedly sleeved on the rotating shaft 51. The two fixed frames 53 are respectively fixed on the sides of the two baffles 41. Each fixed frame 53 has a U-shaped structure, and the two ends of the rotating rod 52 are respectively located in the two fixed frames 53.

[0046] A driving assembly is provided on the sliding plate 31, and the driving assembly is used to drive the rotating assembly to operate. The driving assembly includes a gear 61 and two racks 62. The gear 61 is fixedly mounted on the rotating shaft 51, and the two racks 62 are respectively arranged on both sides of the gear 61, and the two racks 62 are mirror-imaged. The two racks 62 are both engaged with the gear 61, and the tops of the two racks 62 are fixed with connecting rods 63. The ends of the two connecting rods 63 away from the corresponding racks 62 respectively pass through the two second holes and extend to the outside of the curing box 1. The gear 61 and the two racks 62 are both located inside the partition box 81.

[0047] During the curing process, the staff can use the sliding assembly to stir the mud in the curing box 1. Specifically, the staff can control the excavator and use the excavator bucket to push the top rod 34, so that the top rod 34 drives the sliding plate 31 to move inside the curing box 1. Figure 7As shown, in the initial state, the baffle plate 41 at the upper end is opposite to the opening 33 at the upper end, and the baffle plate 41 at the lower end is staggered with the opening 33 at the lower end. At this time, the opening 33 at the upper end is blocked by the upper baffle plate 41, and the opening 33 at the lower end is not blocked. In this case, when the sliding plate 31 moves inside the solidifying box 1, the upper half of the sliding plate 31 will squeeze the mud in the solidifying box 1, so that the mud passes through the opening 33 at the lower end. Under the pushing action of the sliding plate 31, the mud in the upper half of the solidifying box 1 will surge toward the lower half of the solidifying box 1. When the sliding plate 31 moves to one end of the solidifying box 1, the staff controls the bucket to press the higher connecting rod 63 downward. When the connecting rod 63 is pressed down, it can move downward and drive the corresponding rack 62 to move downward. When the rack 62 moves downward, it can drive the gear 61 to rotate, causing the rotating shaft 51 to rotate. When the rotating shaft 51 rotates, it will drive the rotating rod 52 to rotate. Figure 7 and Figure 8 As shown, the two ends of the rotating rod 52 extend into the two fixing frames 53 respectively. Therefore, when the rotating rod 52 rotates, its two ends can push the two fixing frames 53 respectively, so that the two baffles 41 move synchronously in opposite directions. When the rack 62 moves down to the extreme position, the positions of the two baffles 41 are just swapped. In this state, the opening 33 at the lower end is blocked by the lower baffle 41, and the opening 33 at the upper end is not blocked, that is, Figure 8 The status shown.

[0048] After adjusting the positions of the two baffles 41, the staff uses the bucket to push the top rod 34 to move in the opposite direction, causing the sliding plate 31 to move in the opposite direction. In this process, since the opening 33 at the upper end is not blocked, the lower half of the sliding plate 31 will squeeze the mud in the solidification box 1, causing the mud to pass through the opening 33 at the upper end. Under the pushing action of the sliding plate 31, the mud in the lower half of the solidification box 1 will surge toward the upper half of the solidification box 1. Further, when one of the racks 62 drives the gear 61 to rotate, the rotation of the gear 61 can drive the other rack 62 to move upward, which makes it possible for one of the connecting rods 63 to be dug. When the bucket is pressed down, the other connecting rod 63 can be pushed out. Therefore, every time the sliding plate 31 moves to the end position of the curing box 1, the staff can continuously adjust the position of the two baffles 41 by pressing down the connecting rod 63, and repeat this process. The movement of the sliding plate 31 inside the mud is used to stir the mud. Traditional excavator bucket stirring can often only perform simple and local turning of the mud, and it is difficult to ensure the overall uniformity of the mud. This special stirring method can respectively squeeze and push the mud in the upper and lower parts of the curing box 1, so that the mud can fully surge and mix in different areas, which significantly improves the uniformity of stirring.

[0049] A partition box 81 is arranged on one side of the sliding plate 31, and the partition box 81 is connected to the sliding plate 31 through two L-shaped rods 82. A first hole is opened on the side of the partition box 81, and two second holes are opened on the top surface of the partition box 81. As for the gear 61 and the two racks 62, these components are arranged inside the partition box 81, and the partition box 81 provides a relatively sealed space for them and blocks the mud from contacting these components. First, in the environment of mud solidification treatment, the mud often contains various impurities, chemicals and moisture. If these substances come into direct contact with components such as the gear 61 and the rack 62, they can easily cause corrosion and wear to them, reducing the service life and reliability of the components. Reliability, and the presence of the partition box 81 effectively isolates the mud and components, avoiding such direct contact, thereby greatly reducing the risk of corrosion and wear, extending the service life of the components, and reducing the maintenance cost of the equipment. Secondly, the viscosity and particulate matter of the mud may adhere to and accumulate on the surface of the component, affecting the normal operation of the component, resulting in poor engagement between the gear 61 and the rack 62, jamming, slipping and other phenomena, which in turn affects the accuracy and stability of the entire mixing system. The partition box 81 separates the component from the mud, prevents the mud from interfering with the component, ensures that the gear 61 and the rack 62 can engage and transmit smoothly and accurately, and ensures the accuracy and reliability of the mixing operation.

[0050] A damping assembly is provided inside the partition box 81, and the damping assembly includes a fixed rod 71, a slot 72, a movable rod 73, a damping plate 75 and a damping wheel 76. The fixed rod 71 is fixed to the inner bottom surface of the partition box 81, and the slot 72 is opened at the top end of the fixed rod 71. The movable rod 73 is movably inserted into the slot 72. The groove wall of the slot 72 and the outer surface of the movable rod 73 fit each other. The top end of the movable rod 73 extends to the outside of the slot 72 and is fixedly connected to the damping plate 75. The damping wheel 76 is fixedly sleeved on the rotating shaft 51. The damping plate 75 and the damping wheel 76 are in contact with each other. The top surface of the damping plate 75 is provided with an arc surface adapted to the damping wheel 76. The damping plate 75 and the damping wheel 76 are both made of rubber material.

[0051] For the rotating shaft 51, the damping assembly arranged in the partition box 81 provides a damping effect thereon. Specifically, under the elastic force of the connecting spring 74, the movable rod 73 always tends to move upward, so that the damping plate 75 always tends to press the damping wheel 76. Under the pressing action of the damping plate 75, a large friction force can be generated between the damping plate 75 and the damping wheel 76. This friction force can prevent the damping wheel 76 and the rotating shaft 51 from rotating easily. The rotating shaft 51 will only rotate when the staff controls the bucket to press down the connecting rod 63. This design improves the reliability of the stirring operation, helps to control the flow direction and stirring effect of the mud, and thus improves the efficiency and quality of the entire mud solidification process.

[0052] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
