Description

Technical Field

[0002] During the long-term use of bridges and roads, cracks of varying degrees will occur due to local overpressure or long-term direct sunlight. In order to ensure the safety of bridges and roads, it is necessary to reinforce the cracks on the bridges in a timely manner.

[0003] Generally, the bridge crack reinforcement structure includes a reinforcement steel plate, on which bolts are arranged, and a groove is opened along the circumference of the crack. The reinforcement steel plate is connected to the groove by bolts, and a casting hole is opened on the reinforcement steel plate. When in use, the crack is first cleaned, a groove is opened along the circumference of the crack, and then the reinforcement steel plate is placed on the groove, bolts are connected to the bottom wall of the groove, and slurry is poured from the casting hole on the reinforcement steel plate, so that the slurry fills the space between the reinforcement steel plate and the crack, and fills the groove to make the road surface smooth.

[0004] Although this can improve the bearing capacity and durability of the bridge to a certain extent, in actual applications, the crack reinforcement effect may still be not durable and long-lasting.
