Rotating type self-reset bridge pier anti-collision guardrail structure

Abstract

The invention discloses a rotating type self-reset bridge pier anti-collision guardrail structure which comprises a collision resisting mechanism and a buffering mechanism. The buffering mechanism comprises an inner rubber air cushion floating block, a grooved steel block and a fixing steel plate which sleeve the outer portion of a bridge pier. The fixing steel plate is annularly fixed to the inner end of the top of the inner rubber air cushion floating block. The inner wall of the fixing steel plate is arranged outside the bridge pier, and a gap is formed between the inner wall of the fixingsteel plate and the bridge pier. The collision resisting mechanism comprises an anti-collision steel plate of an annular structure and an annular slider. The inner wall of the anti-collision steel plate is connected with the outer wall of the slider through a plurality of steel columns. The slider is in sliding fit with a slide groove in the outer wall of the fixing steel plate. The collision resisting mechanism on the outer portion and the buffering mechanism on the inner portion can rotate, so the anti-collision guardrail structure has high capacity of absorbing energy and can push away a nose and still keep most of energy on a ship.

Description

technical field [0001] The invention relates to the technical field of bridge pier anti-collision technology, in particular to a rotary self-resetting bridge pier anti-collision guardrail structure. Background technique [0002] In recent years, my country's economy has developed rapidly, and the country has vigorously developed transportation resources. With the improvement of bridge construction technology in our country, more and more bridges have been built, including large-scale cross-sea bridges, and many inland areas provide urban areas on both sides of the river. Bridge across the river for transportation path. In order to improve the efficiency of freight transport between regions and save transportation time and costs, more and more bridges across the river will be built. However, while the bridge provides land traffic, it must also have a water navigation channel. When the ship is navigating on the water, due to the lack of indicators in the channel, the ship may ...

AI Technical Summary

Problems solved by technology

[0003] However, the research on the anti-collision of bridge piers in our country is relatively late. Most of the anti-collision devices use direct structural crush deformation, which will generate a large amount of energy during collisions and cause damage to the anti-collision facilities. Frequent maintenance is required, and the damage to the ship is also serious. bigger
