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 connected in sections with mortise and tenon or bolt joints, with each section weighing less than 10 tons.
2. Core Features: Floating along the pier pylon axis with the water level, always matching the collision height of ships; the inner damping element can prevent long-term fatigue from water flow, with easy transportation, installation, and replacement after damage.
3. Protection Effect and Application ScenariosThe shell deforms and the material crushes progressively upon impact to absorb energy in stages, reducing 25% to 35% of the impact force. Simultaneously, the rounded corner structure guides the ship's direction, providing双向 protection for both 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. Some sections feature steel-clad composite structures for enhanced rigidity, secured in specific locations with bolts or rebated dowels.
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 various scenarios.
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. Structure CompositionCored around "steel base + composite coating," it includes steel-clad composite shells, reinforced webbing, closed-cell energy-absorbing cores, and damping elements, with ultraviolet absorbers added to the surface.
2. Core FeaturesThe steel-based matrix ensures rigidity, while the outer composite material offers corrosion, weathering, and impact resistance; weighing just 1/4 of pure steel equipment, it supports both floating and fixed installations. Modular joints facilitate easy disassembly and require no painting maintenance.
3. Protection Effect and Application ScenariosThe shell deforms, the core material crushes, and damping is applied to dissipate energy gradually during impact. The fiber-reinforced structure disperses loads and can recover deformation, suitable for long-term protection in complex aquatic environments.
