Description

Road and bridge crack reinforced structure

Technical Field

The invention relates to the technical field of road and bridge construction, in particular to a road and bridge crack reinforcing structure.

Background

Along with the rapid development of cities, roads and bridges are built more and more, but after the roads and bridges are used for a long time, cracks are generated due to damage caused by impact of hard objects or expansion caused by heat and contraction caused by cold, the strength of the damaged part is reduced after the cracks are generated, the bearing capacity is greatly reduced, the roads and bridges are more easily corroded by rainwater, if the cracks are not treated, the damage is continuously enlarged, and finally the roads or bridges need to be rebuilt or even scrapped.

With the continuous installation and use of the road and bridge crack reinforcing structure, the following problems are found in the use process:

1. traditional road and bridge crack reinforced structure does not have waterproof construction, and the fracture takes place once more easily after receiving the erosion of rainwater or ponding after restoreing.

2. The traditional road and bridge crack reinforcing structure only repairs cracks simply and does not enhance the stability between the device and a road surface or a bridge.
