Embodiment 1

[0087] Embodiment 1: In this embodiment, as Figure 4 As shown, the bionic grass 4 is arranged on the partition rib 31 .

[0088] The partition rib 31 constitutes the installation guide of the bionic grass 7, and the bionic grass 7 is arranged at intervals along the extension direction of the partition rib 31, so that the arrangement of the bionic grass 7 is more orderly, and it is convenient to use mechanized equipment Automatic processing, improve processing efficiency.

Embodiment 2

[0089] Embodiment 2: In this embodiment, as Figure 5 As shown, the bionic grass 7 is set in the deposition tank 32 .

[0090] The bionic grass 7 is arranged in the sedimentation tank 32. When sediment is deposited in the sedimentation tank 32, the sediment can further press the roots of the bionic grass 7, so that the bionic grass 7 and the The connection of the grid frame 3 is more stable, preventing the bionic grass 7 from detaching from the grid frame 3 under the push of the waves.

[0091] As a preferred embodiment of this application, such as Figure 4 , Figure 9 As shown, the anchor body 6 includes a rod body 61, an upper nut 62, a lower nut 63, an upper anchor plate 64 and a lower anchor plate 65, the upper nut 62 is arranged on the upper end of the rod body 61, and the lower The nut 63 is arranged at the lower end of the rod body 61; the first fastening portion 66 is formed between the upper anchor plate 64 and the lower anchor plate 65, and the lower anchor plate...

Abstract

The application discloses a modular marine foundation scour protection device and its installation method, belonging to the technical field of marine foundation protection. The device includes a plurality of protection units, and the protection units include a first shaped net, a geotextile, a second shaped net, The grid frame, the bionic grass and the anchoring body, the first shaping net, the geotextile, the second shaping net, the grid frame and the bionic grass are stacked sequentially from bottom to top, and the anchoring body has a first fastening part and a second fastening part The first fastening part penetrates the protection unit, and the second fastening part extends into the seabed soil to securely connect the protection unit with the seabed soil. This application realizes the combination of active and passive protection methods. The geotextile covering method is passive protection, and the geotextile is used to resist the impact of waves, thereby reducing the erosion of seabed soil near the ocean foundation by waves. The grid frame and bionic grass constitute active protection against waves, disturbing the water flow around the foundation of the ocean, and achieving the purpose of reducing the brush.

Description

technical field [0001] The application belongs to the technical field of marine foundation protection, and in particular relates to a modular marine foundation scour protection device and an installation method thereof. Background technique [0002] The offshore foundation is the carrier of offshore wind power structures and offshore oil and gas platforms. The stability of the offshore foundation is related to the safe operation of the entire life cycle of the superstructure. However, the existence of the marine foundation will disturb the initial three-dimensional flow field structure at the installation position of the foundation, the flow velocity of the water around the foundation will increase, and the soil in the vicinity of the foundation will be washed away, resulting in the growth of the exposed section of the foundation, which will seriously reduce the bearing capacity of the foundation force, threatening the safety and stability of marine structures. In order to ...
