Highway bridge pier anti-collision structure combined with non-Newtonian fluid

Abstract

The invention relates to a highway bridge pier anti-collision structure combined with a non-Newtonian fluid. The highway bridge pier anti-collision structure comprises an energy dissipation buffer layer, an anti-collision layer and a filling material layer, wherein the energy dissipation buffer layer is arranged around the outer wall of a bridge pier in a covering manner; the anti-collision layeris arranged outside the energy dissipation buffer layer in a sleeving manner; the inner side wall of the anti-collision layer is connected to the side wall of the energy dissipation buffer layer; thefilling material layer is vertically arranged and supported between the inner side wall of the anti-collision layer and the outer side wall of the anti-collision layer; energy-absorbing materials arefilled in the gap between the filling material layer and the inner side wall of the anti-collision layer and the gap between the filling material layer and the outer side wall of the anti-collision layer; the filling material layer comprises a plurality of anti-collision units; the anti-collision units are closely distributed in an array manner; every two adjacent anti-collision units are integrally connected; and each of the anti-collision units comprises a first connecting piece, a second connecting piece, a third connecting piece and a fourth connecting piece. The highway bridge pier anti-collision structure combined with the non-Newtonian fluid is stable in structure; and the highway bridge pier anti-collision structure greatly improves the overall rigidity and effectively protects thebridge pier which is impacted.

Description

technical field [0001] The invention relates to the field of bridge pier anti-collision, in particular to a highway pier anti-collision structure combined with non-Newtonian fluid. Background technique [0002] With the vigorous development of the transportation industry and economic construction, a large number of bridges have been built and the number of vehicles has continued to increase, making the probability of vehicles hitting bridge piers increasing. The impact of a vehicle on a bridge pier is not only likely to cause tragedies such as vehicle crashes and deaths, but also reduces the bearing capacity and durability of the bridge structure to a certain extent during the design life. The excessive displacement of the pier top caused by the collision will directly affect the safety of the bridge support As well as the stability of the upper beam body, it may even cause the upper structure to fall off in severe cases. [0003] At present, for the protection of bridge pi...
