A. Buoyant Collision Protection Device

1. Structural compositionThe core is composed of a fiber-reinforced shell, internal energy-dissipating lattice, closed-cell energy-absorbing material, and damping elements. It is assembled in sections using mortise and tenon joints or bolts, with each section weighing less than 10 tons.
2. Core FeaturesFloating along the pier piling axis with the water level using its own buoyancy, it always matches the ship collision height; the internal damping element can prevent long-term fatigue from water flow, with convenient transportation, installation, and easy replacement after damage.
3. Protection Effect and Application ScenariosThe shell deforms and the material crushes progressively upon impact to absorb energy, reducing the impact force by 25% to 35%. Simultaneously, the rounded corner structure guides the vessel's转向, providing dual protection for the bridge and the vessel, and is compatible with the protection of piers in navigable waterways.

II. Fixed Anti-Collision Device

1. Structural compositionBased on steel or composite materials, internally filled with high-performance closed-cell energy-absorbing material, with some sections utilizing steel-clad composite structures for increased rigidity, and secured in specific locations with bolts or rebated rebars.
2. Core FeaturesSturdy installation with no risk of displacement, made from high-strength materials to withstand water flow and harsh weather erosion, durable with low maintenance requirements, and customizable for specific environments.
3. Protection Effect and Applicable ScenariosSuitable for stable water level or key protection areas, such as highway pier protection, which can reduce the impact force of vehicles by over 60%, ideal for long-term fixed-point protection.

Section 3: Collision Protection Equipment with Steel Composite Materials

1. Structural compositionCored with "Steel Base + Composite Coating," it includes steel-clad composite shells, reinforced webbing, closed-cell energy-absorbing cores, and damping elements, with UV absorbers added to the surface.
2. Core FeaturesThe steel substrate ensures rigidity, while the outer composite material offers corrosion resistance, weather resistance, and impact resistance; weighing only 1/4 of pure steel equipment, it supports self-floating or fixed installation. Modular connections facilitate easy assembly and disassembly, and require no painting or maintenance.
3. Protection Effect and Application ScenariosDuring impact, energy is gradually dissipated through shell deformation, core material crushing, and damping buffering. The fiber-reinforced structure can distribute loads and recover deformation, making it suitable for long-term protection in complex aquatic environments.
