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 application discloses a deep-water rapid-flow strong-tide cofferdam outer ring anti-scour device, which comprises a buffer assembly, a mud surface protection mechanism and an energy dissipation mechanism, the mud surface protection mechanism comprises a guide fin, a segmentation cage, a connecting rib plate, a cavitation tube, a guide rod, a translation screw rod and a gas outlet end, the guide fin is in threaded connection with the translation screw rod, and the outer contour of the segmentation cage is in close fit with the inner contour of the guide fin. The mud surface protection mechanism is arranged, so that the device can avoid the problems that the mud surface is washed away by water flow or the mud surface is washed downward due to insufficient protection of the mud surface, and further the bearing capacity of the cofferdam is caused, the cofferdam is inclined and collapsed, and quality and safety accidents are caused.
