Problems solved by technology

Although the ice-breaking edge has played the role of breaking the ice row to a certain extent, but because there is no isolation and shock absorption effect, the mobile ice row directly collides with the bridge pier. The long-term impact has caused damage to the bridge pier and buried safety hazards

Embodiment Construction

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] It should be noted that, if there are directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention, they are only used to explain the difference between the various components in a certain posture If the specific posture changes, the directional indication also changes accordingly.

[0027] In addition, if the description of "first", "second", etc. is involved in the pr...

Abstract

The invention discloses an anti-drift ice impact device for a bridge, comprising a bridge pier, a buffer mechanism is arranged on the outside of the bridge pier, and the buffer mechanism includes a plurality of arc corrugated steel plates arranged on the outside of the bridge pier and a plurality of corrugated steel plates arranged between the corrugated steel plates and the bridge pier. There are several elastic shafts fixed on the inner side of the transition ring, the free end of the elastic shaft is provided with a porous rubber buffer pad, and a first buffer spring is provided between the corrugated steel plate and the transition ring, A second buffer spring is arranged between the transition ring and the porous rubber buffer pad; an ice breaking mechanism is also arranged on the transition ring; a trigger mechanism is also arranged between the transition ring and the corrugated steel plate. Compared with the traditional treatment method of preventing drift ice from hitting the bridge, the device has better buffering and shock absorption effect, and can effectively reduce the damage to the bridge pier caused by the impact of floating ice.

Description

technical field [0001] The invention relates to the technical field of bridge anti-collision, in particular to a bridge drift ice anti-collision device. Background technique [0002] More and more bridges are erected on the navigable waterways, and they are getting bigger and bigger, and there are also super-long sea-crossing or island-connected bridges. [0003] Bridges are important buildings in the production and life of human society and an important part of transportation infrastructure, especially bridges in some key positions, which are often called lifeline projects. my country is a country with a lot of ice damage. It is located in the rivers, lakes and seas in the north of China. There are ice conditions in winter, involving 16 provinces and regions and the northern part of the Bohai Sea and the Yellow Sea. The rivers, lakes and seas that flow through these provinces open up each year when the temperature rises, and the ice sheet cracks into huge ice sheets that c...
