One, 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 or bolt connections, with each section weighing less than 10 tons.
2. Core FeaturesFloating along the pier pier axis with the water level using its own buoyancy, always matching the collision height of the ship; the internal damping element can avoid long-term abrasion fatigue caused by water flow, and it is convenient for transportation, installation, and easy to 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, the rounded structure guides the vessel's转向, providing protection for both the bridge and the vessel in both directions, and is compatible with navigation waterway pier protection.

II. Fixed Anti-Collision Device

1. Structure compositionBased on steel or composite materials, internally filled with high-performance closed-cell energy-absorbing material. Partially utilizes steel-clad composite structures for increased rigidity and secured to specific locations with bolts or rebars.
2. Core 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 scenarios.
3. Protection Effect and Application ScenariosSuitable for stable water level areas or key protection zones; such as road bridge pier protection, which can reduce vehicle impact force by over 60%, ideal for long-term fixed-point protection.

Section 3: Collision Protection for Steel Composite Materials

1. Structure CompositionAt the core is a "Steel Substrate + Composite Coating" design, featuring steel-coated composite shells, reinforced webs, closed-cell energy-absorbing cores, and damping elements, with added ultraviolet absorbents 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 either floating or fixed installation, modular connection for easy assembly and disassembly, and requires no painting maintenance.
3. Protection Effect and Application ScenariosDuring impact, energy is gradually 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.
