Anti-collision structure of submerged floating tunnel
The invention discloses an anti-collision structure of a submerged floating tunnel. The anti-collision structure of the submerged floating tunnel is characterized in that the anti-collision structure is composed of anti-collision energy dissipation casing pipes covering the outer wall of the floating tunnel, anti-collision pipe sections capable of being disassembled and assembled independently are arranged on the axial section of the anti-collision energy dissipation casing pipes, the anti-collision pipe sections are pipe pieces arranged on the outer wall of the floating tunnel in the periphery direction in a sectioned mode, all the pipe pieces are fixedly connected to the outer wall of the floating tunnel through high-strength bolts, and the axial direction is the passage direction of the submerged floating tunnel. All the pipe pieces are in a multi-layer composite structure which comprises a polyurethane elastic panel located on the surface and an energy dissipation cushion layer located in the inner layer, a closed pressure-bearing water cavity is formed between the polyurethane elastic panel and the energy dissipation cushion layer, and the pressure-bearing water cavity is filled with pressure-bearing water. The anti-collision structure is applied to the submerged floating tunnel, is large in elasticity, resistant to corrosion and capable of bearing collision of large-tonnage ships and sufficiently absorbing impact energy.
