Bridge anti-collision device and bridge

Abstract

The invention provides a bridge anti-collision device. The bridge anti-collision device comprises an inner side coating structure (1), and outer side coating structure (2), an energy absorption shockproof module and a shockproof spring (3), wherein the energy absorption shockproof module is arranged in a space between the outer side coating structure (2) and the inner side coating structure (1); the energy absorption shockproof module comprises an energy absorption buffering material (4), the energy absorption buffering material (4) surrounds the outer side of the inner side coating structure(1), and meanwhile, the energy absorption buffering material (4) is located on the inner side of the outer side coating structure (2) and is separated from the inner side of the outer side coating structure (2); and the shockproof spring (3) is arranged in a channel of the radial direction of the inner side coating structure (1) extending outwards formed in the energy absorption buffering material(4).

Description

technical field [0001] The invention relates to the technical field of bridge protection, in particular to a bridge anti-collision device and a bridge. Background technique [0002] With the improvement of highway coverage in our country, three-dimensional traffic engineering has also developed rapidly, which has led to a rapid increase in the number of bridge structures, spans, seismic grade requirements, and pier heights. [0003] A widely used form of bridge is the road overpass bridge, which is designed to relieve traffic pressure, but it also brings many uncertainties. At present, if the bridge structure of the highway overpass bridge designed according to the traditional method encounters collision, it may not only cause damage to the vehicle, but even cause casualties in severe cases. Traffic paralysis, directly or indirectly lead to huge economic losses. According to current reports, it has been found that domestic and foreign vehicles collide with expressway bridg...

Problems solved by technology

Although the structural design of the outer ring layer is convenient for assembly and maintenance, it is unfavorable for non-positive external impacts, and it is easy to cause structural damage.

[0009] However, the current flexible protective structures either use a single layer of rubber to form an anti-collision cushion, or use expensive new materials to form a complex deformation connection mechanism. The protection efficiency of a single layer of rubber is limited, and the protection effect on the pier column is not good. However, the anti-collision measures of the deformation mechanism constructed of new materials are often costly. Although they can better achieve the purpose of deformation and energy absorption to protect the pier column, the high cost makes it difficult for these devices to be used for small and medium-sized bridge pier columns.
