An anti-scouring concrete repair device

Abstract

The invention discloses an anti-scouring concrete repairing device. The anti-scouring concrete repairing device comprises a mixing and stirring device and a slurry supplement pipe. The mixing and stirring device is used for stirring concrete slurry, and the concrete slurry is injected into concrete cracks through the slurry supplement pipe. The anti-scouring concrete repairing device is characterized in that the mixing and stirring device can cyclically work to prepare materials first and then to discharge the materials, and a plurality of pipelines arranged between the mixing and stirring device and the slurry supplement pipe. The anti-scouring concrete repairing device has the advantages that the cracks are fully filled, the probability of slurry leakage is lowered, the surface flatnessis high after reinforcement, and a grouting pipe can slide in the cracks to achieve slurry supplement; the mounting stability of a support is high, and a wall is not likely to be damaged, or the adhesion strength of a plate body is high; intermittent material supplement and quantitative stirring are conducted, so that raw material waste is reduced, the cracks are fully filled, the probability of slurry leakage is lowered, the surface flatness is high after reinforcement, the grouting pipe can slide in the cracks to achieve slurry supplementation; and the mounting stability of the support is high, and the wall is not likely to be damaged, or the adhesion strength of the plate body is high.

Description

technical field [0001] The invention relates to the technical field of concrete reinforcement, in particular to an abrasion-resistant concrete repair device. Background technique [0002] Concrete pouring refers to the process of pouring concrete into the mold until it is plasticized. In civil engineering, concrete and other materials are put into the mold to make a predetermined shape. Usually, concrete defects include the following situations. First, the interior of the concrete has voids and voids, which are commonly known as "two skins"; The surface of the concrete is not cleaned properly, and the concrete surface is stuck when the formwork is removed; or, the formwork release agent is not evenly applied, and some parts are missing or invalid, and the concrete surface and the formwork are bonded to cause pockmarks; third, cracks and cracks appear on the concrete surface The problem. The general mechanism of cracks is generally believed to be due to the fact that the in...

Problems solved by technology

The crack defect reinforcement of the prior art has the following deficiencies: First, for cracks in the vertical direction or cracks on the inclined surface, the problem of grout leakage is likely to occur when using the traditional grouting method; When the concrete slurry is injected into the crack in the direction of gravity, the slurry will flow down under the action of gravity, and it is difficult to fill the depth of the crack, resulting in low reinforcement efficiency; second, when the crack is long, only through the concrete itself Leveling, it is difficult to ensure that it can fill the entire crack. At this time, it is necessary to move the position of the grouting pipe to realize the filling of the crack. In the existing technology, the grouting is often completed by manually moving the grouting pipe Third, after the crack is reinforced, there will be a large repair mark between the reinforced area and the non-reinforced area. From the surface, the reinforced area will bulge a little compared to the non-reinforced area, which is Because the reinforced concrete is naturally solidified in the cracks, its surface smoothness is poor; Fourth, when actually reinforcing, it is usually necessary to install a bracket to fix the position of the grouting pipe, because it is for repairing vertical cracks or oblique Cracks on the drape; in the prior art, the grouting pipe is usually fastened by riveting or manual holding. Although the riveting method has a better fastening effect and saves labor, this method is to destroy the wall or plate. achieved at the expense of the body
