Anti-collision wall structure

Abstract

The invention discloses an anti-collision wall structure which comprises a wall body, a support, a pipeline groove and a dustproof panel. The wall body is arranged on a bridge, the support is arrangedon the side, away from the bridge, of the wall body, the pipeline groove is formed in the support, and the pipeline groove can be used for bridge pipeline laying. According to the anti-collision wallstructure, the support is arranged on the side, away from the bridge, of the wall body and the pipeline groove is formed in the support and used for pipeline arrangement, so that a problem that the wind load of the bridge is increased because the pipeline is arranged below the sidewalk is solved; the wall body can prevent vehicles from rushing down the bridge and the anti-collision effect is achieved; the pipeline is arranged on the side, away from the bridge, of the wall body, the dustproof panel can shield the pipeline groove and the support, the dustproof effect is achieved; meanwhile, theattractiveness of the bridge is enhanced; the phenomenon that the pipelines are damaged due to inconsistent stress can be avoided when the anti-collision device is applied to a double-width bridge structure, and the service life of the pipeline is prolonged.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an anti-collision wall structure. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. [0003] In the design and construction of the bridge, the layout of the bridge pipeline needs to be considered. Some bridges raise the sidewalk, and the pipeline trough is arranged under the sidewalk slab. This method of pipeline layout increases the overall vertical height of the bridge, increases the area of ​​the windward side of the bridge, and increases the wind load; the entire bridge shape looks heavy, which affects the beauty of the bridge; s...

AI Technical Summary

Problems solved by technology

For double-width expressway viaducts, there is usually a gap of 0.5m to 2m between the left and right sides, and the bridge crossing pipeline is usually laid between the two bridges through hangers, such as figure 1 As shown, the bridge pipeline bracket 1 is set between the two bridges for laying pipelines, but under the action of temperature load, traffic load or earthquake load, the horizontal deformation between the two bridges is likely to be inconsistent In turn, the bridge pipeline bracket 1 is damaged, which affects the normal use of the bridge and increases the maintenance cost of the bridge.
