1. Made of flexible composite materials, filled with high-performance closed-cell energy-absorbing materials, which can greatly reduce the impact force, multi-level energy absorption, step-by-step buffering, effectively reduce the impact force of the vehicle by more than 60, prolong the impact time, and reduce the damage of the vehicle, so as to achieve the purpose of protecting personnel, bridge piers and vehicles.
2. Compared with steel anti-collision facilities, composite anti-collision facilities are corrosion-resistant, anti-aging, and have a service life of more than 30 years under normal use without being hit by external forces, and do not require maintenance during use.
3. Good structural performance, high toughness, high energy absorption, strong fatigue resistance, good elasticity, can be recovered after deformation, and can achieve "small collision is not broken, medium collision can be repaired, and large collision is easy to replace".
4. The connection form is simple and convenient, the disassembly and assembly are convenient, the transportation and installation are convenient and fast, and the anti-collision facilities are composed of multiple independent units, which are convenient and efficient to disassemble and assemble, and easy to maintain and replace.
5. Small size and light weight.
The specific gravity of the composite shell is 1 4 of the steel shell, and the specific gravity of the high-performance closed-cell energy-absorbing material is lighter, the overall weight is light and the volume is small, which not only does not require any mechanical equipment for installation and replacement, but also can minimize the occupation of vehicle traffic area and reduce traffic safety hazards.
6. Strong plasticity, according to the specific pier form, combined with the installation position and conditions of the vehicle, various anti-collision structures and types such as rectangular, circular, square, polygonal, special-shaped, fixed, self-floating and so on can be designed.
7. It has a beautiful appearance and night reflection function, which can play a certain role in the early warning and warning of passing vehicles.
