Automatic grouting device for concrete crack defects with high adhesion strength

Abstract

The invention discloses an automatic slurry filling device for a concrete crack defect with high adhesion strength, which comprises a slurry filling pipe, wherein the concrete slurry is injected intothe concrete crack through the slurry filling pipe; and also comprises a machine frame, an electric sliding element, an electric lifting element, a rubber sleeve, a trowel, a first supporting rod, a first sucking disc, a second supporting rod and a abutted element; the electric sliding element is in sliding fit with the machine frame, the electric lifting element is arranged on the electric sliding element, the lifting end of the electric lifting element is connected with the slurry filling pipe, and the trowel is sleeved at the periphery of the slurry filling pipe through the rubber sleeve. The first sucking disc is arranged on the end part of the first supporting rod; the connecting end of the abutted element is slidably mounted on the end part of the second supporting rod, and the abutted end of the abutted element can be contacted with the trowel. The device has the advantages that the crack can be fully filled, the slurry leakage condition is reduced, the flatness of the surface after filling the slurry is high, the slurry filling pipe can achieve sliding and grouting in the crack, and the installation stability of a bracket is high, no damage is caused on a wall body or the adhesion strength of a plate body is high.

Description

technical field [0001] The invention relates to the technical field of concrete reinforcement, in particular to a concrete crack defect automatic grouting device with high adhesion strength. 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 considere...

AI Technical Summary

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
