Bridge pier anti-collision device of metal hollow ball potting resin matrix composite material

Abstract

The invention discloses a bridge pier anti-collision device of a metal hollow ball potting resin matrix composite material and relates to the bridge pier anti-collision device. The problems are solvedthat in the prior art, a bridge pier is damaged by an impact object and the energy absorption and protection effects of an anti-collision device are poor. The bridge pier anti-collision device of themetal hollow ball potting resin matrix composite material comprises an inner-layer stress steel plate layer, an outer-layer stress steel plate layer, upper-layer steel plates, lower-layer steel plates and a metal hollow ball potting resin matrix composite material structural layer; the inner-layer stress steel plate layer, the metal hollow ball potting resin matrix composite material structural layer and the outer-layer stress steel plate layer are fixedly arranged on the outer circumference of the bridge pier from inside to outside in sequence; the upper-layer steel plates are fixedly arranged at the upper ends of the inner-layer stress steel plate layer, the metal hollow ball potting resin matrix composite material structural layer and the outer-layer stress steel plate layer; the lower-layer steel plates are fixedly arranged at the lower ends of the inner-layer stress steel plate layer, the metal hollow ball potting resin matrix composite material structural layer and the outer-layer stress steel plate layer.

Description

technical field [0001] The invention relates to a bridge pier anti-collision device. Background technique [0002] The impact of vehicles or ships on the pier is the main factor causing damage to the lower structure of the bridge. Generally speaking, although the mass of the vehicle is smaller than that of the ship, its speed is very high, and the kinetic energy when it hits the pier is also very large. In the design of pier anti-collision facilities, fundamentally speaking, the basic principles are based on the energy absorption and momentum buffer mechanism to protect the pier. Comprehensively inspecting the material selection and structural design strategies of existing devices, it can be found that most of the research focuses on high-strength materials in material selection, so that the stiffness of the impactor and the protective device tend to be at the same level. In terms of structure, flexible objects such as rubber have been used to optimize the structure to redu...
