Description

Technical Field

[0001] The present invention belongs to the technical field of road traffic facility protection, and in particular relates to an assembled highway traffic anti-collision protection pier. Background Art

[0002] Isolation piers are an important type of traffic facility, which mainly play the role of isolation and protection, and are used to limit the driving or parking area of ​​cars. Ordinary isolation piers do not have a shock-absorbing and energy-consuming effect, and are prone to cause double damage to vehicles and isolation piers in the event of danger. Isolation piers, also known as water horses, are a major type of traffic facility. At present, isolation piers are mainly set up on highways and urban roads where vehicles are prone to collide with fixed facilities in the middle of the road, such as: road turns, road booths, toll booths and entrances and exits of elevated roads, parking lots, communities, gardens, gas stations, etc., which play an isolation role, not only preventing traffic accidents, but also maintaining smooth traffic. However, the existing isolation piers do not have a significant shock-absorbing and energy-consuming effect, nor do they have a certain anti-collision ability. After a collision, the piers are damaged by the Due to the poor anti-collision and shock absorption ability, it is easy to cause harm to vehicles and passengers. With the development of the economy, the construction of highway infrastructure will develop rapidly. In recent years, with the development of highway construction, the application and types of isolation facilities have also been greatly developed. Isolation facilities have also increasingly shown their important role in traffic safety and environmental protection. Most of the isolation piers set up at the turning points of the road, the roadside booths, toll stations and the entrances and exits of the elevated roads have poor buffering and energy consumption. When a car loses control and hits, it often causes car damage and death, especially the broken debris and fragments that injure people more seriously. Its poor anti-collision and shock absorption characteristics cannot effectively prevent the occurrence of danger. With the large-scale construction of highways, urban interchanges, etc. and the substantial increase in the number of cars in the world, the incidence of traffic accidents has also shown an upward trend. At present, the existing isolation piers on the market do not have sufficient buffering and shock absorption when in use. After the car hits, it can only rely on its own deformation damage to absorb energy. Its deformation and energy absorption capabilities are limited, and the isolation piers are easy to break under the impact of the car, resulting in inability to use normally, and it is also easy to cause secondary damage to the safety of vehicles and crew members.
