[0016] The floating energy-dissipating and noise-reducing device of the present invention is composed of a noise-reducing honeycomb panel 1, a supporting frame 2, a floating body 3 and a tightening hoop 4, and the supporting frame 2 is composed of several FRP I-shaped profiles 21, connecting rods 22 and the spacers 23 are equidistantly connected into a grid structure; the floating body 3 is a sealed tubular body, and the tubular floating body 3 is fixed below the support frame 2 by tightening the tie 4; the noise-reducing honeycomb panel 1. It is formed by splicing and bonding several pieces of PVC plastic molding boards 16. There are several special-shaped pipes with open ends on it. Each special-shaped pipe is provided with a vertical collection pipe 11 from top to bottom. Tube 12, curved surface energy dissipation tube 13, multi-stage energy dissipation groove 14 and diversion groove 15 are arranged on the curved surface energy dissipation tube 13; the cross-sectional shape ...
