The scour prevention measures adopt soft connection, avoid the adverse effect of construction on exposed cables around the single pile foundation 1, adapt to different foundation types, and are suitable for the bottom protection repair after the scour prevention measures of the original offshore single pile foundation 1 fail.

The tires 3 have a diameter of 60-150cm, and the distance between two adjacent sets of tires 3 is the radius of one set of tires 3 close to the monopile foundation 1. The tires 3 are connected in series through flexible connecting pieces 8, and the number of the tires 3 connected in series in the same straight line direction of the same horizontal plane is 5-8. The sole guard is arranged mainly within 10m around the mono pile structure in plan view. And when the tire strings are staggered and overlapped on the vertical surface, the thickness elevation is about 50cm higher than the original mud surface, so that a stable anti-scouring structure is formed.
At least 3 groups of support rods 5 are arranged between the buoyancy circular ring 7 and the substrate 2, one end of each group of support rods 5 is fixedly connected with the buoyancy circular ring 7, and the other end of each support rod 5 is fixedly connected with the substrate 2; the buoyancy ring 7 comprises two groups of semicircular buoyancy blocks 71, the two groups of buoyancy blocks 71 are detachably connected, and locking pieces 10 are arranged at the connecting positions of the two groups of buoyancy blocks 71; a plurality of groups of connecting rings are fixedly arranged on the circumference of the buoyancy circular ring 7. The diameter of the buoyancy circular ring 7 is larger than that of the single pile foundation 1, and the buoyancy circular ring 7 cannot collide with the single pile foundation 1 under the condition of large seawater scouring force due to the support of the support rods 5; the buoyancy ring 7 can be made of compressed foam plates, plastic plates or light materials. The locking piece 10 can be fixed by bolts, or can be fixed by nylon ropes or double buckles. The support rod 5 may be steel bars, corrosion-resistant steel pipes, etc. The support rods 5 support the anti-scouring net, so that the anti-scouring net can be prevented from being greatly sunken when the anti-scouring net is scoured by seawater, and the practicability of the anti-scouring net is improved. Wherein the buoyancy ring 7 comprises a first buoyancy ring 701, a second buoyancy ring 702 and a third buoyancy ring 703, the scour protection net comprises a first scour protection net 401, a second scour protection net 402 and a third scour protection net 403, wherein the first buoyancy ring 701 is connected with the first scour protection net 401, the second buoyancy ring 702 is connected with the second scour protection net 402, and the third buoyancy ring 703 is connected with the third scour protection net 403; the three-layer anti-scouring net can effectively play a role in anti-scouring, and the design of the multi-layer anti-scouring net is also beneficial to improving the anti-scouring degree, and the arrangement of the first anti-scouring net 401 is the most inclined, and the inclination degree of the third anti-scouring net 403 is the least, but can bear seawater scouring of different degrees.
One side of the anti-scouring net 4, which is close to the buoyancy circular ring 7, is detachably connected with the connecting ring, and one side of the anti-scouring net 4, which is close to the substrate 2, is fixedly connected with the substrate 2 through the anchoring piece 6; the energy dissipation balls 9 are rotatably connected on the net wires 12 of the adjacent meshes on the anti-scouring net 4; the energy dissipation balls 9 are rotatably connected on the flexible connecting pieces 8 between the adjacent tires 3.

when the tire is assembled, the number of the tires 3 in each string is 5-8 in plan view, the diameters of the tires 3 are 60-150cm, the distance between the adjacent tires 3 is about the radius of the tires 3, and the total length is not more than 10m. The tire strings are overlapped in a staggered manner from the vertical face, and the thickness elevation is about 50cm higher than the base 2 (the original mud surface), so that a stable anti-scouring structure is formed; the tyre 3 close to the single pile foundation 1 is fixed by a fixing rod 11; the tires 3 of different layers do not need to be connected, and the tires 3 of different layers only need to be lapped.
After the tire 3 is placed, an anti-scouring net is placed; the two matched buoyancy blocks 71 are separated, then the buoyancy blocks are buckled around the single pile foundation 1, one end of the anti-scour net is tightly bound with the connecting ring of the buoyancy ring 7, the other end of the anti-scour net is connected with the base 2 through the anchoring piece 6 and the base 2, the anchoring piece 6 is required to be inserted into the base 2 from a gap between the tires 3, and the contact part of the anti-scour net and the tires 3 is only needed to be overlapped or contacted without additional fixing pieces for fixing.
Embodiment two: the difference between this embodiment and the first embodiment is only that: in the embodiment, the tires 3 with different heights are connected through nylon ropes or steel wires, and the tire 3 nets in the plane close to the base 2 are all fixedly connected with the base 2 through the fixing rods 11, so that the tires 3 are more fixed, and the method is suitable for the uneven sea area of the base 2; by changing the connection mode of the tire 3 and the substrate 2, the practicability of the substrate 2 can be effectively improved.
