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, connected in sections with mortise and tenon or bolt joints, with each section weighing less than 10 tons.
2. Core FeaturesWith its buoyancy, it floats along the pier piling axis with water levels, always matching the collision height of ships; the inner 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 ScenariosThe shell deforms and the material crushes progressively during impact to absorb energy in stages, reducing 25% to 35% of the impact force. Meanwhile, the rounded structure guides the ship's转向, offering双向 protection to both the bridge and the vessel, and is compatible with the protection of piers in navigable waterways.

II. Fixed Collision Protection Device

1. Structure 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 by bolts or rebated reinforcement.
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 Scenarios: Suitable 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 for Steel Composite Materials

1. Structure CompositionCored around "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. Key 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 joints facilitate disassembly and require no painting or maintenance.
3. Protection Effect and Applicable ScenariosDuring impact, energy is progressively dissipated through shell deformation, core material crushing, and damping cushioning. The fiber-reinforced structure can distribute loads and recover deformation, suitable for long-term protection in complex aquatic environments.
