Bridge deck crack repairing device for bridge reinforcement

Abstract

The invention discloses a bridge deck crack repairing device for bridge reinforcement and relates to the technical field of bridge reinforcement. The bridge deck crack repairing device for the bridgereinforcement comprises a plate body, a handle, moving wheels, steel plates, a concrete stirrer, a cement pump and a joint filling mechanism, wherein a left end and a right end of the bottom of the handle are fixedly connected to a left side and a right side of a rear side of the top of the plate body respectively; the number of the moving wheels is four; the four moving wheels are movably connected with convex parts on four sides of the top of the plate body through pin shafts; and a horizontal height of the bottom of the plate body is higher than the horizontal height of the bottom of the moving wheels. By the adoption of the bridge deck crack repairing device for the bridge reinforcement, two discharging mechanisms are respectively close to two sides of an inner wall of a crack under anacting force of a return spring, and concrete is discharged from the discharging mechanisms through work of the concrete stirrer and the cement pump, so that the concrete is close to the inner wall of the crack when being discharged into the crack through the discharging mechanisms, and occurrence of a large number of air holes in joint filling concrete is avoided.

Description

technical field [0001] The invention relates to the technical field of bridge reinforcement, in particular to a bridge deck crack repairing device for bridge reinforcement. Background technique [0002] The bridge deck part of the bridge is an important path for driving. After long-term use, since the modern bridge technology has not yet reached a high level, it is inevitable that bridge deck cracks and other damage will occur during the bridge’s completion and use. When cracks occur on the bridge surface, the cracks are usually repaired by filling them with concrete. The current commonly used repairing method basically involves the construction team arriving at the position where the cracks appear on the bridge deck, mixing cement on site and filling the cracks. During the filling process, a large amount of air will inevitably be filled into the cracks along with the cement, which affects the cracks. The quality of the filled concrete has the hidden danger of low strength ...

The current commonly used repairing method basically involves the construction team arriving at the position where the cracks appear on the bridge deck, mixing cement on site and filling the cracks. During the filling process, a large amount of air will inevitably be filled into the cracks along with the cement, which affects the cracks. The quality of the filled concrete, which has a low strength, may easily lead to the hidden danger of cracking again in a short time
