One, Floating Collision Avoidance 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 FeaturesWith its buoyancy, it floats along the pier pylon axis with water levels, always matching the ship's collision height; the internal damping element prevents long-term fatigue from water flow, and transportation, installation are convenient, and replacement is easy after damage.
3. Protection Effect and Application 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 bidirectional protection for both the bridge and the vessel, and is compatible with the protection of bridge piers in navigable waterways.

II. Fixed Anti-Collision Device

1. Composition StructureBased 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 fixed at specific locations with bolts or rebars.
2. Core FeaturesSturdy installation with no risk of displacement, made with high-strength materials to withstand water and harsh weather erosion, durable with low maintenance requirements, and customizable for specific scenarios.
3. Protection Effect and Application ScenariosSuited for stable water level or key protection areas, such as highway pier protection that can reduce vehicle impact force by over 60%, ideal for long-term fixed point protection.

Section 3: Collision Protection Equipment with Steel Cladding

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