One, Floating 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 FeaturesFloating along the pier piers axis with the water level, always matching the collision height of the ship; the inner damping element can prevent long-term fatigue from water flow, and is easy for transportation, installation, and replacement 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 turn, providing protection for both the bridge and the vessel in both directions, and is compatible with navigation channel pier protection.

II. Fixed Collision Protection Device

1. Structural compositionBased on steel or composite materials, internally filled with high-performance closed-cell energy-absorbing material. Some parts utilize steel-clad composite structures for enhanced rigidity, and are fixed at specific locations with bolts or rebated dowels.
2. Core FeaturesSturdy installation with no risk of displacement, made of 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 levels or key protection areas; such as bridge pier protection on highways, 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 Cladding

1. Structural CompositionAt the core, "steel base + composite coating," including steel-clad composite shells, reinforced web plates, 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, weather, and impact resistance; weighing only 1/4 of pure steel equipment, it supports self-floating or fixed installation. Modular connections facilitate disassembly and require no painting 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, suitable for long-term protection in complex aquatic environments.
