Large-diameter wheel disc type gravity anchor on seabed

Abstract

The application provides a submarine large-diameter wheel disc type gravity anchor, which is used for solving the technical problems that the existing ring-shaped anchor has poor integrity and is difficult to manufacture and install due to large size and weight. The submarine large-diameter wheel disc type gravity anchor comprises a plurality of prefabricated box girder segments arranged in a ring-shaped array, and the plurality of prefabricated box girder segments are sequentially spliced into a ring. The prefabricated box girder segment is a fan-shaped ring segment, the two ends of the prefabricated box girder segment are respectively provided with a first mortise-tenon structure and a second mortise-tenon structure, and the first mortise-tenon structure of the prefabricated box girder segment is connected with the second mortise-tenon structure of the adjacent prefabricated box girder segment. The two side bottom ends of the prefabricated box girder segment are provided with flange edges, and the bottom ground end faces of the flange edges are flush with the bottom ground end face of the prefabricated box girder segment. The mortise-tenon structures arranged at the two ends of the prefabricated box girder segment are used for connecting the adjacent prefabricated box girder segments, the ring-shaped anchor formed by splicing the plurality of prefabricated box girder segments, and the prestressed cable is further used for strengthening the integrity of the ring-shaped anchor.
