A. Self浮漂防撞装置

1. Structure CompositionThe core is composed of a fiber-reinforced shell, internal energy-dissipating lattice, closed-cell energy-absorbing material, and damping elements. It is connected in sections using mortise and tenon joints or bolts, with each section weighing less than 10 tons.
2. Core FeaturesWith its buoyancy, it floats along the pier piers' axis with water levels, always matching the ship's collision height; the internal damping element prevents long-term fatigue from water flow, and it is easy to transport, install, and replace after damage.
3. Protection Effect and Applicable ScenariosDuring impact, energy is progressively absorbed through shell deformation and material crush, reducing 25% to 35% of the impact force. Simultaneously, rounded structures guide ship转向, providing bidirectional protection for both the bridge and the ship, and are compatible with navigation waterway pier protection.

II. Fixed Collision Protection Device

1. Structural compositionBased on steel or composite materials, internally filled with high-performance closed-cell energy-absorbing material, partially utilizing steel-clad composite structures for enhanced rigidity, and secured to specific locations with bolts or rebated rebars.
2. Key FeaturesSturdy installation with no risk of displacement, constructed with high-strength materials to withstand water flow and harsh weather erosion, durable with low maintenance requirements, and customizable for specific application scenarios.
3. Protection Effect and Application ScenariosIdeal for stable water level areas or key protection zones, such as highway pier protection that can reduce vehicle impact force by over 60%, suitable for long-term fixed-point protection.

Section 3: Collision Protection Equipment with Steel Cladding

1. Structure compositionAt the core, "Steel Substrate + Composite Coating," featuring steel-clad composite shells, reinforced webs, closed-cell energy-absorbing cores, and damping elements, with UV absorbents added to the surface.
2. Core FeaturesThe steel base ensures rigidity, while the outer composite material offers corrosion, weather, and impact resistance; weighing only 1/4 of pure steel equipment, it supports either floating or fixed installation, and modular joints facilitate disassembly and require no painting maintenance.
3. Protection Effect and Applicable ScenariosDuring impact, energy is progressively dissipated through shell deformation, core material crush, and damping cushioning. The fiber-reinforced structure can distribute loads and recover deformation, suitable for long-term protection in complex aquatic environments.
