Description

Technical Field

[0001] The invention relates to the technical field of reinforcement structures, and in particular to a road bridge crack reinforcement structure and a reinforcement method. Background Art

[0002] After the roads and bridges are laid, they will gradually become fragile after being subjected to high temperatures, severe cold and rain during the process of being put into use. If they are subjected to large loads, they will crack, causing cracks in the roads and bridges. If they are not repaired in time, the original cracks will gradually increase until the roads and bridges are damaged.

[0003] The most commonly used method for repairing road and bridge cracks is the filling and repair method. When repairing, a deep groove is first chiseled along the crack, and then cement mortar, epoxy mortar, asphalt, reinforcing agent and other bonding materials are embedded in the groove. The repair is completed after the bonding material solidifies, but the interior does not support the structure. It only relies on the strength of the bonding material itself to support the rolling pressure of vehicles. However, if the traffic volume on the repaired section is too large or there are too many heavy-loaded vehicles, especially at night when engineering vehicles often pass by, the engineering vehicles carrying engineering materials will exert greater pressure on the joint between the filler and the original roadbed. Only relying on the strength of the bonding material itself to support the rolling pressure of engineering vehicles can easily cause it to be damaged or fall off, and it needs to be repaired again. Therefore, a road and bridge crack reinforcement structure and reinforcement method are needed. Summary of the invention

The two semicircular blocks push the two fixing columns into the inner walls of the two through holes under pressure and compress the two springs;

[0020] Among them, when the two semicircular blocks contact the inner walls of the two second fixing holes, under the action of the two springs, the two semicircular blocks and the two fixing columns are clamped into the inner walls of the two second fixing holes to complete the fixing of the fourth reinforcement column.

The installation method of the other multiple fourth reinforcement columns (21) is the same; After the other plurality of fourth reinforcement columns (21) are installed, the third reinforcement column (17) is taken out; S3: Then, the lower end of the third reinforcing column (17) is passed through the inner wall of the third fixing hole (20) on the fourth reinforcing column (21), and the lower end of the third reinforcing column (17) is clamped into the inner wall of the first fixing hole (9) on the second rectangular groove (10), and the lower surface of the circular plate (18) is in contact with the upper surface of the fourth reinforcing column (21), and then concrete is poured on the inner wall of the second rectangular groove (10) by an external tool to fix the plurality of fourth reinforcing columns (21) and the plurality of third reinforcing columns (17); By arranging a plurality of fourth reinforcement columns (21) and a plurality of third reinforcement columns (17), the plurality of fourth reinforcement columns (21) and the plurality of third reinforcement columns (17) are arranged in a cross shape, and after the concrete is hardened, a concrete block (5) is formed, so that the structural strength of the lower end of the entire reinforcement structure can be improved, and the stability of the bottom of the reinforcement structure can be improved; S4: After the concrete hardens to form a concrete block (5), the concave frame (4) is then taken up and installed on the upper surface of the concrete block (5) through the plurality of circular holes (25) and the plurality of third reinforcement columns (17), and then fixed by a plurality of fixing nuts, and then the clamping plate (16) is taken up as a whole, and the two concave clamping plates (15) and the two clamping plates (16) are clamped together to complete the installation of the protective cover (6); After the protective cover (6) is installed, the reinforcing steel plate (2) is taken out; S5: Then, the lower ends of the plurality of second reinforcing columns (12) on the lower surface of the reinforcing steel plate (2) are sequentially inserted through the inner walls of the first clamping holes (13) on the corresponding first reinforcing columns (3), and finally, the lower ends of the plurality of second reinforcing columns (12) are respectively clamped into the inner walls of the second fixing holes (14) on the corresponding concave frames (4) and the protective covers (6), and the lower surface of the reinforcing steel plate (2) is in contact with the inner walls of the two first rectangular grooves (8); S6: Finally, concrete is poured into the interior of the concave frame (4) through the grouting holes (7) to fix the plurality of first reinforcement columns (3), the plurality of second reinforcement columns (12) and the reinforcement steel plate (2). After the poured concrete hardens, the installation of the reinforcement structure is completed.
