Description

Technical Field

[0001] This application relates to the field of bridge deck pavement repair, and in particular to a hinge joint and bridge deck pavement repair device for hollow slab beam bridges. Background Technology

[0002] Bridge deck pavement repair refers to the maintenance, repair, or replacement of the pavement layer of the bridge superstructure to restore its function and extend the bridge's service life. The main function of bridge deck pavement is to protect the bridge deck from direct damage from vehicle loads and environmental factors, while providing a smooth and non-slip driving surface for vehicles. The hinge joint of a hollow slab beam bridge is the connection structure between adjacent precast slab beams in a prefabricated hollow slab beam bridge. It is usually formed by filling with post-cast concrete or adhesive materials. The pavement at the top of the hinge joint of a hollow slab beam bridge is prone to cracking. Cracks in both the bridge deck pavement and the hinge joint of a hollow slab beam bridge are usually repaired by grouting with molten asphalt.

[0003] Based on the above, the following problems were found: Current bridge deck pavement repair devices usually consist of a trolley carrying molten asphalt and a nozzle. When in use, it usually requires two people to operate, one person pushes the trolley forward and the other person controls the nozzle to pour the molten asphalt onto the cleaned cracks, which is inconvenient to use.
