Highway bridge protection pier with high anti-collision performance

Abstract

The invention discloses a highway bridge protection pier with high anti-collision performance. The protective pier is characterized by comprising supporting column pieces, a bearing beam frame, a protective base, a side anti-collision compression-resistant assembly and a peripheral protection assembly; one end of each supporting column piece extends and is buried in the ground surface, and the multiple supporting column pieces are evenly arranged at intervals and form a supporting main shaft of the highway bridge; the bearing beam frame is coaxially fixed to the upper end of the supporting column piece, abuts against and makes contact with the highway bridge and is used for stably bearing a highway bridge body; the protective base is used for stably supporting the end part of the supporting column piece; and the side anti-collision compression-resistant assembly is arranged outside the supporting column pieces in an umbrella-shaped circumferential array mode, and one end of the side anti-collision and pressure-resistant assembly penetrates through the protection base and extends into the ground surface synchronously with the supporting column piece to be buried in the ground surface, and the peripheral protection assembly sleeves and is fixed in the side, close to the protective base, of the supporting column piece.

Description

technical field [0001] The invention relates to the technical field of highway bridge equipment, in particular to a protective pier for highway bridges with high anti-collision performance. Background technique [0002] In the construction of ordinary roads and expressways, bridges are an important part of road construction. With the development of the transportation industry, more and more overpasses are designed, and the number of bridge piers exposed on both sides of the road is gradually increasing. With the rise of the automobile industry, the tonnage of trucks is getting higher and higher, and the speed is getting faster and faster. The threat of vehicles to the safe operation of bridges is increasing. In addition, in recent years, it is not uncommon for bridge piers to be damaged and collapsed due to vehicles and ships hitting bridge piers, which affects traffic safety; the road bridge piers in the prior art have poor impact resistance and lack external protection.

Problems solved by technology

In addition, in recent years, it is not uncommon for bridge piers to be damaged and collapsed due to vehicles and ships hitting bridge piers, which affects traffic safety; the road bridge piers in the prior art have poor impact resistance and lack external protection. The fracture of the column will cause the overall instability of the bridge, loss of transportation capacity, and incalculable economic losses. Therefore, it is necessary to propose a protective pier for highway bridges with high anti-collision performance to solve the above problems
