Description

Technical Field

[0001] The invention belongs to the field of traffic safety facilities, and in particular relates to an inner-outer combined highway crash bucket. Background Art

[0002] Crash barrels are a very common road traffic safety device, mainly installed in places where cars are prone to collide with fixed facilities on highways and urban roads. For example, at road bends, entrances and exits of roads and elevated roads, they can play a role in isolation, warning and collision prevention. They can buffer accidental collisions with vehicles, effectively reduce the impact force, and greatly reduce the damage to vehicles and people. Therefore, it can significantly reduce the damage to vehicles and personnel. The reflective material on its surface can be affixed with an indication label as needed. The plastic anti-collision barrel can be filled with water or yellow sand. After being filled with water and yellow sand, it will have the ability to buffer the impact force. The plastic anti-collision barrel has a good buffering effect on traffic impact force after being filled with water or yellow sand, but when it is not needed, the water and yellow sand can be poured out and it can be easily and flexibly moved away. The anti-collision barrel is made of materials with good elasticity, high strength and strong performance. Reflective materials will be affixed to the surface. When the light shines on it, a reflective effect can be achieved. It is clearly visible day and night. In some more dangerous areas, such as road turns, exits and entrances, and highways with faster speeds, it has been widely used in places where there are safety risks. On the one hand, the reflective material set on the anti-collision barrel can effectively play the role of traffic prompts. On the other hand, when a vehicle collides with the anti-collision barrel, a anti-collision barrel with buffering performance is set, which can greatly buffer the huge impact force generated by the collision, thereby greatly reducing the severity of traffic collision accidents. Heavy consequences, and the existing crash barrels are generally made of plastic and other materials, which are not strong enough and have poor buffering performance. At the same time, the current crash barrels are generally light in weight, and are easily moved under the action of external force impact, and are easy to scratch passing vehicles and pedestrians, causing great safety hazards and easily causing secondary injuries. Under the action of huge impact force, due to its insufficient strength in design, weak impact resistance and poor buffering performance, the existing crash barrels are generally prone to deformation of the crash barrel structure. Crash barrels are very necessary traffic safety infrastructure. my country's highways have been developed since the 1980s, and they play an important role in the development of the national economy and society. Crash barrels are very important safety protection facilities for highways. Crash barrels can effectively play a role of prevention, warning and safety protection, and can effectively reduce the losses caused by accidents, effectively reduce the probability of vehicle damage caused by accidental collisions, reduce the probability of property losses and casualties, and protect people's lives and property from infringement to the greatest extent.
