1、 Self floating collision avoidance device

1. structural compositionThe core consists of a fiber-reinforced shell, an internal energy dissipation lattice, closed cell energy absorbing materials, and damping elements. It is connected in sections using mortise and tenon or bolt joints, with a single section weight of less than 10 tons. ​
2. Core FeaturesUsing its own buoyancy to float along the axis of the bridge pier with the water level, always matching the height of the ship's impact; The inner damping element can avoid long-term collision fatigue caused by water flow, and is easy to transport and install. It is also easy to replace after damage. ​
3. Protective effect and applicable scenariosDuring impact, energy is gradually absorbed through shell deformation and material crushing, reducing the impact force by 25% to 35%. At the same time, the rounded corner structure guides the ship to turn, providing bidirectional protection for bridges and ships, and adapting to the protection of bridge piers in navigable waters. ​

2、 Fixed anti-collision device

1. structural compositionUsing steel or composite materials as the matrix, filled with high-performance closed cell energy absorbing materials, partially reinforced with steel covered composite structures to enhance rigidity, and fixed to specific locations through bolts or planted reinforcement. ​
2. Core FeaturesThe installation is firm and there is no risk of displacement. High strength materials are used to resist water flow and severe weather erosion. It has strong durability and low maintenance requirements, and can be designed specifically for different scenarios. ​
3. Protective effect and applicable scenariosSuitable for water level stability or key protection areas, such as highway bridge pier protection, which can reduce vehicle impact force by more than 60%, suitable for long-term fixed point protection. ​

3、 Steel clad material anti-collision facilities

1. structural compositionBased on the core of "steel based+composite material coating", it includes a steel coated composite shell, reinforced web plate, closed cell energy absorbing core material, and damping element, with the addition of ultraviolet absorbers on the surface. ​
2. Core FeaturesThe steel matrix ensures rigidity, while the outer composite material combines corrosion resistance, weather resistance, and impact resistance; Weighing only 1/4 of pure steel facilities, it supports self floating or fixed installation, with segmented connections for easy disassembly and maintenance without painting. ​
3. Protective effect and applicable scenariosDuring impact, energy is gradually dissipated through shell deformation, core material crushing, and damping buffering. Fiber reinforced structures can disperse loads and restore deformation, making them suitable for long-term protection in complex water environments.
