Description

Technical Field

[0001] The utility model belongs to the technical field of isolation piers, and in particular relates to an impact-resistant and restorable central isolation pier for a highway. Background Art

[0002] Isolation piers are facilities that isolate vehicles and pedestrians and protect safety. They can effectively eliminate vehicles occupying sidewalks, walkways, and fire passages, and can also manage the random entry and exit of vehicles. They have a simple structure and are affixed with yellow reflective film. Traditional isolation piers are cast with concrete, which is not convenient for buffering impact forces. Therefore, some hollow plastic anti-collision barrels have appeared on the market for use in isolation piers. Anti-collision barrels are mainly set on highways and urban roads where cars are prone to collide with fixed facilities in the middle of the road to play an isolating role. Anti-collision barrels are made of highly elastic and high-strength modified plastics. When a car collides with the equipment, the impact force can be effectively reduced. Therefore, the damage to the car and people can be significantly reduced. The anti-collision barrel is hollow, and fillers such as water or sand can be injected into the interior to increase the counterweight.

[0003] However, traditional crash barrels do not have impact-resistant reinforcement mechanisms inside. When the impact force is large, the crash barrel's own elasticity is not enough to effectively buffer the impact. If the deformation of the crash barrel is too large, there is a risk of damage due to dislocation and pulling. In addition, traditional crash barrels are not easy to repair quickly after being dented. It is difficult and labor-intensive to manually repair the dented parts of the barrel.

[0004] Therefore, there is a need for a highway impact-resistant and recoverable central isolation pier to solve the problems in the prior art that the anti-collision barrel cannot effectively buffer the impact force by relying on its own elasticity when the impact force is large, and it is difficult to repair the barrel body after it is dented.
