This invention discloses a submarine cable anti-scouring device and its construction method, applicable to the field of submarine cable protection technology. The invention includes a filter layer and a flexible protective layer. The filter layer comprises multiple filter pads arranged sequentially along the axial direction of the submarine cable on the surface of the cable and / or the seabed, with adjacent filter pads overlapping. The flexible protective layer comprises multiple flexible protective pads arranged sequentially along the axial direction of the cable on the filter layer. At least one flexible protective pad is provided at the overlap of any two adjacent filter pads to press the filter layer firmly against the surface of the cable and / or the seabed. This application, through the cooperation of the filter layer and the flexible protective layer, improves the stability of the submarine cable anti-scouring device to reduce inter-segment displacement and possesses adaptive capability to seabed subsidence deformation, effectively enhancing the anti-scouring effect of the submarine cable.

The invention belongs to the technical field of vibration isolation, and particularly relates to an integrated carbon fiber composite material damping filling sandwich structure raft frame and a preparation method. The raft frame comprises two supporting plates and a support arranged between the two supporting plates. The supporting plate comprises an upper panel and a lower panel; the metal honeycomb interlayer is provided with a plurality of filling holes and is arranged between the upper panel and the lower panel; the surface of the whole supporting plate is made of the carbon fiber composite material, damping of the raft frame is increased, the middle layer is provided with the metal material, the rigidity of the raft frame is increased, and the damping effect of the raft frame is improved. Meanwhile, the filling holes of the metal honeycomb interlayer are filled with the damping material filling blocks, so that the overall weight of the raft frame is reduced, the damping of the raft frame is further increased, and the problems that in the prior art, a metal raft frame is small in damping, and a pure carbon fiber material raft frame is insufficient in rigidity, large in weight and limited in vibration reduction effect are solved.
