Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the anti-scour effect of the existing protective measures is not good, so as to provide a gridded cemented riprap with stronger anti-scour ability formed on the periphery of the offshore structure. Anti-scouring structure; the anti-scouring structure can also reduce the thickness and range of riprap around offshore structures, thereby reducing the comprehensive cost of anti-scour protection

Embodiment 1

[0042] A gridded cemented riprap anti-scouring structure, such as Figure 1-Figure 3 As shown, it includes: riprap particles 12, uniformly distributed around the periphery of the structure 2; gel 13, filled between the riprap particles 12 to connect part of the riprap particles 12 from top to bottom to form a cemented stalagmite 11: There are several cemented stalagmites 11 distributed around the structure 2 in a grid pattern, and the cemented stalagmites 11 have a structure of small top and large bottom, and the periphery of cemented stalagmites 11 is surrounded by riprap particles 12 .

[0043] A gridded cemented riprap anti-scouring structure provided by the present invention is composed of cemented stalagmites 11 and surrounding riprap particles 12, wherein the cemented stalagmites 11 are used as the core structure to play the role of rigid skeleton support and effectively resist wave water erosion , and ensure the stability of the surrounding riprap particles 12; as an au...

Abstract

The invention discloses a gridding cementation riprap anti-scour structure which comprises riprap particles evenly distributed on the periphery of a structure by a circle. The gelling material is filled among part of the riprap particles and is used for connecting the riprap particles into a whole from top to bottom to form a cemented gelling; the plurality of cemented gulcottes are distributed around the structure in a gridding manner, and the cemented gulcottes are of a structure with a small upper part and a large lower part. The invention overcomes the defect that the anti-scour effect of the existing protective measures is poor, and provides the gridding cemented riprap anti-scour structure which has stronger anti-scour capacity and is formed on the periphery of an offshore structure. The anti-scour structure can also reduce the riprap thickness and the riprap range around the offshore structure, so that the anti-scour protection comprehensive cost is reduced.

Description

technical field [0001] The invention relates to the technical field of anti-scour of marine engineering basic structures, in particular to a gridded and cemented riprap anti-scour structure. Background technique [0002] The ocean is rich in resources and is an important area for future development. Offshore wind power has the advantage of being clean and efficient, and is an important part of new energy. The basic structure of offshore wind power is an important supporting structure for the development and utilization of wind energy resources, and it is also an extremely important offshore structure. The layout of offshore structures will change the current flow field, resulting in the formation of local scour pits around the structures, which will affect the bearing capacity of offshore structures and seriously threaten the safety of the upper wind turbine and other structures and the stability of the overall structure. [0003] At present, protective measures such as ri...
