Bridge pier capable of reducing vehicle impact force

Abstract

The invention discloses a bridge pier capable of reducing a vehicle impact force. The bridge pier comprises a ground and a sliding cavity located in the ground; a movable buffer device is arranged inthe sliding cavity; a moving groove is formed between an upper end wall of the sliding cavity and an upper end surface of the ground in a communicating mode; the movable buffer device comprises longitudinal sliding grooves located in the left end wall and the right end wall of the sliding cavity; a sliding block is connected into the longitudinal sliding groove in a sliding manner; a transverse sliding rod is fixedly connected between the two sliding blocks; and the transverse sliding rod is connected with a sliding shell in a sliding manner. According to the device, when a vehicle sideslips,the impacted bridge pier generates a section of displacement along the direction of the road and the direction vertical to the road; and under the action of the buffer springs, the speed of the vehicle is rapidly reduced, possible harm to the vehicle and personnel in the vehicle is decreased, meanwhile, rollers are arranged on the surface, facing the road, of the bridge pier, the vehicle can be prevented from rushing out of the road to the maximum extent, and the speed of the vehicle can be rapidly reduced.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a bridge pier for reducing vehicle impact force. Background technique [0002] During the driving process of the vehicle, due to a series of factors such as vehicle speed, weather, driver, etc., the vehicle loses control and rushes out of the road or hits the bridge pier on the road surface, causing vehicle damage and casualties. The bridge piers on both sides of the existing road cannot be moved. A direct impact has too much impact on vehicles and people, without a buffer function. At the same time, when the vehicle deviates along the road, it may fly out of the road along the roadbed. Contents of the invention [0003] In view of the deficiencies of the above-mentioned technologies, the present invention proposes a bridge pier for reducing the impact force of vehicles, which can overcome the above-mentioned deficiencies. [0004] A bridge pier for reducing the impa...
