Description

Technical Field

[0001] The utility model relates to the technical field of bridge maintenance, and in particular to a municipal road bridge crack reinforcement structure. Background Art

[0002] Most municipal road bridges are made of cast cement. With the increase of bridge construction time and the increasing traffic volume, cement cast bridges will inevitably produce a small number of cracks. Therefore, the cracks in the bridges need to be reinforced. Bridge reinforcement generally refers to restoring or improving the bearing capacity of existing bridges by strengthening components and improving structural performance, so as to extend their service life and meet the requirements of modern transportation.

[0003] Most of the existing cracks on bridges are on the bridge deck, and the cracks on the bridge deck are easy to repair, but there are columnar connecting columns on the bridge. If cracks appear on the columnar connecting columns, when the staff repair the cracks on the columnar connecting columns, the cement used for repair cannot adhere to the columnar connecting columns before solidifying, and it is easy to fall off the columnar connecting columns. In addition, it is difficult to repair the cracks below the columnar connecting columns, and the staff need to hold them up with a pallet, which is easy to fall off the columnar connecting columns. At the same time, a supporting device is required to assist in the repair process of the columnar connecting columns to prevent the columnar connecting columns from breaking during the repair process.
