1.What is a crash pad?
With the increase in highway mileage and the characteristics of high speed limits and large traffic volumes, highway accidents are becoming more frequent. In highway accidents, collision with guardrails is a common accident form among many accident forms. Especially at the diverging end of the main line exit of the expressway, the diverging end of the ramp, etc., anti-collision mats came into being.
At present, there is no unified standard for the definition of crash pads in the transportation sector industry standards.
Crash pads can effectively absorb collision energy and reduce the hazards of frontal collisions. In side collisions, they can change the collision angle of the vehicle and guide the vehicle in the correct direction.
2.Our Company
Qingdao Taicheng has the qualification certificate for highway engineering construction enterprise issued by the Ministry of Construction and the Ministry of Communications, and passed the ISO9001 standard quality system certification in June 2010. Since its establishment, the company has experienced rapid and steady development, and its business has expanded to India, Brazil, the United States, Bangladesh and other countries, with assets increasing at a rate of 20% per year.
3.How anti-collision pad work?
The anti-collision pad is a facility that absorbs the collision energy of the vehicle to stop the vehicle safely and changes the direction of the vehicle to avoid serious injury to the occupants. Its main function is to reduce the severity of accidents. On the other hand, it also serves as a warning and inducement through its surface color and graphic symbols.
The principle of conservation of momentum is generally composed of sand-filled or water-filled anti-collision tubes (piers) of different masses arranged in a certain order. After the vehicle collides with the anti-collision pad, the momentum of the vehicle is transferred to the anti-collision tube in turn, which reduces the speed of the vehicle and the anti-collision tube, and finally reduces the speed of the vehicle to less than 15km/h.
Practice has proven that the existing standard section of highway guardrails can basically effectively reduce the severity of traffic accidents. However, collision accidents at the ends of guardrails at highway traffic diversions often cause serious injuries to the accident vehicles and drivers and passengers. Therefore, it is necessary to install anti-collision pads at the highway traffic diversions or in front of obstacles. When a vehicle collides, the crash pad deforms to absorb the collision energy, thereby reducing the degree of injury to the occupants.

5.The structure of the crash pad
Guideable crash pads generally consist of ends, energy-absorbing materials, side beams, diaphragms and back supports. After the vehicle collides with the crash pad, the energy of the collision vehicle is absorbed through the deformation and energy-absorbing material of the end part, and the back support is used to resist the impact of the vehicle. Energy-absorbing materials are generally foam materials or rubber materials. Anti-collision pads based on this principle have good energy-absorbing effects and guiding effects for front and side collisions of vehicles. Moreover, after the system is collided, the main components can be reused, making maintenance convenient, fast and low-cost. The disadvantage is that the initial installation is slightly complicated and costly.
