Technical Field

[0001] The present invention belongs to the field of offshore engineering technology, and in particular relates to a shared anchor point type anchor foundation connection structure. Background Art

[0002] As ocean development moves toward deep seas, various floating structures are emerging. These floating structures usually need to be positioned in a certain water area for a long time or for a considerable period of time for operation or waiting for operation. The mooring system is an important component for controlling the range of motion of such floating structures. The mooring system is mainly composed of mooring cables and seabed anchor foundations, which need to provide sufficient horizontal and vertical restoring forces.

[0003] The climate conditions in deepwater areas are harsh, and floating production facilities are large in size and need to be suspended for a long time for convenient operation, which requires facing the problem of mooring positioning under harsh sea conditions. Traditional catenary mooring is difficult to apply to deepwater areas above 1000m due to factors such as insufficient positioning ability, occupying a large amount of platform reserve buoyancy, and difficulty in offshore installation. In recent years, with the gradual maturity of mooring cable materials and technologies, deepwater mooring design technology has developed rapidly.

[0004] In most coastal waters of my country, the physical and mechanical indicators of the shallow seabed soil layer are poor and often cannot directly meet the design requirements. Moreover, with the increase of offshore distance and water depth, the marine engineering environment becomes more severe. Although the anchor piles have a greater depth in the mud and are more suitable for geological conditions and are easier to meet the design requirements of the mooring system, they are also equipped with related connection structures.

[0005] Therefore, it is urgent to design a shared anchor point anchor foundation connection structure to solve the above-mentioned problems. Summary of the invention

[0009] Furthermore, a connecting rib plate is fixedly connected inside the connecting cylinder, and one end of the connecting rib plate away from the connecting cylinder is fixedly connected to the steel pipe pile.

[0010] Furthermore, the specific number of the connecting rib plates is the same as the number of the ear plate groups.

[0011] Furthermore, each connecting rib plate is located between the gaps between every two adjacent ear plate groups.

[0012] Furthermore, it also includes a reinforcing ring plate, which is sleeved outside the steel pipe pile and fixedly connected to the steel pipe pile.

[0013] Furthermore, the reinforcing ring plate is located between the steel pipe pile and the connecting cylinder.

[0014] Furthermore, the reinforcing ring plate is fixedly connected to the ear plate group and the connecting rib plate.

[0015] Furthermore, the reinforcing ring plate is provided with a first opening and a second opening, the first opening is for the ear plate group to be plugged in, and the second opening is for the reinforcing rib plate to be plugged in.

[0021] Please refer to the attached Figure 1 To Attachment Figure 4 A shared anchor point anchoring foundation connection structure of the present invention is described.

[0022] At present, the climate conditions in deepwater areas are harsh, and floating production facilities are large in size and need to be suspended for a long time for convenient operation, which requires facing the problem of mooring positioning under harsh sea conditions. Traditional catenary mooring is difficult to apply to deepwater areas above 1000m due to factors such as insufficient positioning ability, occupying a large amount of platform reserve buoyancy, and difficulty in offshore installation. In recent years, with the gradual maturity of mooring cable materials and technologies, deepwater mooring design technology has developed rapidly.

[0023] In most coastal waters of my country, the physical and mechanical indicators of the shallow seabed soil layer are poor and often cannot directly meet the design requirements. Moreover, with the increase of offshore distance and water depth, the marine engineering environment becomes more severe. Although the anchor piles have a greater depth in the mud and are more suitable for geological conditions and are easier to meet the design requirements of the mooring system, they are also equipped with related connection structures.

[0024] Therefore, the shared anchor point type anchor foundation connection structure includes a ring plate assembly 2 which is sleeved on the outside of the steel pipe pile 1, and a plurality of ear plate groups 3 are connected to the ring plate assembly 2. The plurality of ear plate groups 3 are fixedly connected to the steel pipe pile 1, and the plurality of ear plate groups 3 are arranged in an array with equal spacing with the connecting cylinder 21 as the center. A mooring point 31 is provided on each ear plate 32, and can be connected to the anchor chain through the mooring point 31.

[0025] Preferably, the specific number of ear plate groups 3 is three, and the distance between every two adjacent ear plate groups 3 is 120 degrees, so that the upper load is evenly transferred to the steel pipe pile 1, reducing the torsion of the steel pipe pile 1, and the force is reasonably transferred to the steel pipe pile 1. The steel pipe pile 1 becomes the force-bearing body and resists all-directional loads, preventing damage to components caused by excessive local force concentration, thereby preventing accidents. In other embodiments of the present invention, the ear plate groups 3 can also be other numbers, as long as the ear plate groups 3 can be distributed in an equidistant array and the force is evenly distributed.

[0026] Specifically, each ear plate group 3 includes two ear plates 32 , and mooring points 31 are provided on the two ear plates 32 .

[0027] Furthermore, the annular plate assembly 2 includes a connecting cylinder 21, which is sleeved outside the steel pipe pile 1, and a plurality of ear plate groups 3 are fixedly connected to the connecting cylinder 21, one end of the plurality of ear plate groups 3 is fixedly connected to the steel pipe pile 1, and the plurality of ear plate groups 3 extend outside the connecting cylinder 21 away from one end of the steel pipe pile 1.

[0028] Regarding the fixed connection method between the connecting cylinder 21 and the plurality of ear plate groups 3 and between the plurality of ear plate groups 3 and the steel pipe pile 1, welding is preferred.

The first opening is for the ear plate group 3 to be plugged in, and the second opening is for the reinforcing rib plate to be plugged in. Specifically, the ring plate assembly 2 is formed by welding the connecting cylinder 21, the connecting rib plate 22 and the ear plate group 3 to form a whole. Then, the reinforcing ring plate 4 is inserted into the ear plate group 3 and the connecting rib plate 22 through the first opening and the second opening, so that the reinforcing ring plate 4 is fully inserted.
