Problems solved by technology

The increase of the vertical load on the roof of the bridge and the cantilever, as well as the force and bending moment generated by the wind load on the sound barrier, will easily lead to the calculation of the bearing capacity at the root of the bridge cantilever and the corner of the side box room, which cannot meet the requirements of the code, and may also cause cracks have adverse effects on the durability and safety of the bridge structure

Abstract

The invention discloses a base device for adding a sound barrier to a bridge. The upper end is connected, the upper part of the main support is provided with a hoop, the hoop is connected with the roadway anti-collision guardrail of the bridge, the sound barrier column base is set on the base bracket, and the sound barrier column base is used to install the sound barrier. Adding a sound barrier to the existing bridge is beneficial to the safety of the bridge structure. In addition, the base is set on the outside of the bridge, which does not affect the traffic, and the construction is more convenient.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a base device for adding a sound barrier to a bridge. Background technique [0002] At present, a large number of elevated and overpass structures in urban construction usually take precedence over the development of urban plots. After the transportation network is formed, commercial and residential facilities will be implemented accordingly. On the one hand, these viaducts have made great contributions to urban traffic, and on the other hand, they have also brought serious noise pollution to the lives of residents living nearby. The addition of bridge sound barriers in the later period can effectively solve the noise problem. However, for the current bridges that have been put into operation, the increased load of the sound barrier will have an impact on the lateral calculation of the structure. The lateral force is more sensitive than the longitudinal force o...
