Abstract

The invention discloses a multi-axial crack reinforcement device for road bridges, which comprises a shell and a first filling cavity, a second filling cavity and an injection cavity respectively opened in the shell, an irregular spherical cavity is opened on the top of the shell, and the The first filling cavity and the second filling cavity communicate with the irregular spherical cavity through the first through hole and the second through hole respectively, and the injection cavity communicates with the first filling cavity and the second filling cavity through the communication groove and the fixing hole respectively, The inner wall of the irregular spherical cavity is rotatably connected with a first rotating shaft. In the present invention, under the mutual cooperation of the first filling cavity, the second filling cavity, the injection cavity, the irregular spherical cavity, the arc block, the electric cylinder, the moving block, the communication mechanism and the transmission device, the concrete is injected into the first filling cavity The crack repair fluid is injected into the second filling cavity. The crack repair fluid has good adhesion and can be used as a fixing medium between the concrete and the gap, and can also make the concrete stronger.

Description

technical field [0001] The invention relates to the technical field of bridge gap repair, in particular to a multi-axial crack reinforcement device for road bridges. Background technique [0002] Road bridges are generally composed of several parts such as roadbed, road surface, bridge, tunnel engineering and traffic engineering facilities. The traffic load transmitted by the road surface is an important part of the entire road structure. After the road bridge is laid, it will gradually become fragile after being damaged by high temperature, severe cold and rain for a long time during the process of being put into use. Cracks will appear when a large load exceeds its bearing capacity. If it is not repaired in time, it will gradually increase on the basis of the original cracks until the road bridge is damaged. At this time, it needs to be refurbished, resulting in additional economic costs Spending is a waste of money. [0003] At present, there are many repair methods for...
