Viaduct pier detachable anti-collision device based on non-Newtonian fluid

Abstract

A viaduct pier detachable anti-collision device based on non-Newtonian fluid comprises a strip-shaped anti-collision body and high-strength studs used for fixing, the strip-shaped anti-collision bodycomprises a deformable hard layer, a buffer layer, a rubber bag and a non-Newtonian fluid filler, wherein the deformable hard layer is of a strip-shaped closed structure with a cavity; the buffer layer is arranged between the rubber bag and the deformable hard outer layer, and the buffer layer is filled with rubber; the rubber bag is a closed bag of which the upper end and the lower end are respectively provided with a fluid inlet and a fluid outlet, the fluid inlet and the fluid outlet are led to the exterior of the deformable hard layer, and the interior of the rubber bag is filled with thenon-Newtonian fluid filler; and the strip-shaped closed structure is fixed to a viaduct pier on the pier face of one side deviating from the driving direction through high-strength studs, and meanwhile the strip-shaped anti-collision body and a pier foundation are fixed through the high-strength studs. The beneficial effects are that the anti-collision performance of the non-Newtonian fluid anti-collision device is guaranteed by utilizing the non-Newtonian fluid mechanical property, and the impact force of a vehicle load is effectively buffered.

Description

technical field [0001] The invention relates to a detachable anti-collision device for viaduct piers based on non-Newtonian fluid. Background technique [0002] With the continuous development of science and technology and social economy, infrastructure construction such as roads, railways, and rail transit has developed rapidly. In order to ensure the safety of vehicles and pedestrians as much as possible and reduce the use of land resources, viaducts are used to replace traditional roadbeds. The structure has been widely used in our country, and it has shown outstanding technical advantages in alleviating traffic congestion and improving transportation efficiency. [0003] As an important part of the viaduct, bridge piers play a vital role in the stability and safety of the overall structure. With the increasing traffic flow in cities, traffic safety accidents are very likely to occur at multi-route intersections, especially when vehicles hit bridge piers, which are the m...

AI Technical Summary

Problems solved by technology

In recent years, there have been many traffic accidents in which trucks hit viaduct piers. Because bridge piers are usually made of concrete, although they have high strength, they are relatively brittle. Severe cases cause the viaduct to collapse, causing serious personal and property safety
