One, Floating Collision Prevention 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 piers' axis with water levels, always matching the collision height of ships; the inner damping element can prevent long-term abrasion fatigue caused by water flow, and transportation, installation are convenient, and it's easy to replace after damage.
3. Protection Effect and Applicable ScenariosThe shell deforms and the material crushes progressively upon impact, absorbing energy step by step to reduce 25% to 35% of the impact force. Meanwhile, the rounded corner 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 bridge piers in navigable waterways.

Fixed Anti-Collision Device

1. Structure compositionBased on steel or composite materials, internally filled with high-performance closed-cell energy-absorbing material, partially utilizing steel-clad composite structures for increased rigidity, and secured in specific locations with bolts or rebated anchors.
2. Key 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 application scenarios.
3. Protection Effect and Applicable 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 with Steel Composite Materials

1. Structural compositionAt the core, "steel base + composite coating," featuring steel-clad composite shells, reinforced webbing, closed-cell energy-absorbing cores, and damping elements, with added ultraviolet absorbers to the surface.
2. Core FeaturesThe steel-based body ensures rigidity, while the outer composite material offers corrosion resistance, weather resistance, and impact resistance; weighing just one-fourth of pure steel equipment, it supports either floating or fixed installation, with modular joints for easy disassembly and without the need for painting maintenance.
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, making it suitable for long-term protection in complex aquatic environments.
