Description

Technical Field

[0001] The utility model relates to the field of bridges, and more specifically to a single-column pier reinforcement device for bridges. Background Art

[0002] A single-column pier bridge refers to a bridge supported by a single row of piers. This type of structure is widely used in the construction of bridges, subway stations, high-rise buildings, etc. It has the advantages of small footprint, small visual interference, strong spatial adaptability, beautiful bridge shape, smaller span, and greater economy. However, single-column pier bridges also have some potential problems, such as weak torsional resistance at the pier top and insufficient lateral anti-overturning capacity. In some extreme cases, such as multiple heavily loaded large trucks driving on the same lane on the same side of the bridge at the same time, the bridge may be in danger of overturning. In order to improve the performance of single-column pier bridges, people usually take a series of reinforcement measures.

[0003] In order to improve the performance of single-column pier bridges, the existing technology is to install steel cap beams and rubber bearings on the top of the piers to improve their stability. However, single-column piers of bridges still have certain safety hazards. On the one hand, with the passage of time, the rubber bearings will age, crack, become hollow, etc., resulting in a decrease in the bearing capacity of the bearings, which in turn affects the stability of the entire bridge. On the other hand, if overloaded vehicles or special load conditions act on the bridge, the connection between the steel cap beam and the pier will become loose or cracked, resulting in the steel cap beam being unable to effectively play its reinforcement role.
