Embodiment 1

[0026] A concrete broken slab repair grouting device, comprising a slurry mixing tank 1, a pedestal 29 is arranged below it, and a high-pressure grouting pump 2 connected to the bottom of the slurry mixing tank 1 through a pipeline, the slurry mixing tank 1 is connected to the high-pressure A slurry storage tank 20 is also provided between the grouting pumps 2, and a screen 27 is arranged on the top of the slurry storage tank 20. The upper side of the slurry storage tank 20 is connected with the bottom of the slurry mixing tank 1 through the slurry outlet pipeline 21, and the other side The lower part is connected with the slurry inlet head 10 of the high-pressure grouting pump 2 through the slurry outlet pipeline 21; the slurry mixing tank 1 and the slurry storage tank 20 are respectively provided with a bracket 22, and a motor 23 is fixed on the bracket 22, and the output shaft end of the motor is connected to There is an agitator; the high-pressure grouting pump 2 includes a...

Embodiment 2

[0030] The concrete broken slab repair grouting device and its grouting process are shown in Example 1.

[0031] Adopt the above-mentioned device to complete the method for repairing broken concrete slabs, comprising the following steps: (1) adopt drilling equipment to punch holes in the cracks of the concrete slabs, then bury the grouting nozzles in the holes one by one, the number and positions of the holes should be According to the crack width and depth of the concrete slab, the grout nozzle should be sealed with the hole to prevent the grout from leaking during high-pressure grouting; Control the valve so that the grouting flow rate is 2.5L / min, and it can be injected several times until the grouting pressure and diffusion radius meet the requirements. The grout is made by mixing cement and water in a ratio of 1:1.4; when grouting, When the diffusion radius reaches 1.5m and the pressure of the high-pressure grouting pump in the above device reaches 1.0MPa, stop the grouti...

Abstract

The invention relates to the concrete technical field, in particular to a repairing grouting device of a concrete breaking plate and a method thereof, which solves the problems of prior art which adopts a demolishing and remaking technology requiring much time and work, wasting source, etc. The device consists of a grout mixture stirring barrel, a grout storing barrel, a high-pressure grouting pump which are connected with a piping in sequence, wherein, the high-pressure grouting pump is connected with a grouting piping, and the grouting piping is connected with a grouting nozzle. The method comprises the steps that: the grouting nozzle is arranged after being punched; the grout mixture is compounded and grouted; a groove is made along two sides of a gap by a cutting machine after the grout mixture being solidified and polymer mortar is filled into the groove and a repairing surface is polished and sprayed by grout, etc. The grouting device of the invention has simple structure, reasonable design, low cost, and being capable of meeting the requirements of spot construction, high efficiency, and stable operation with small and exquisite and portable characterizes. The grouting device is matched with a concrete breaking plate through the repairing method, thus greatly improving repairing quality of the concrete breaking plate, reducing construction cost and having certain popularization value.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a concrete broken slab repair grouting device and method. Background technique [0002] After the concrete construction of the white pavement of the expressway, the airport runway, the overall track bed of the railway tunnel, etc., due to the lack of early maintenance of the concrete slab and other reasons, cracks appear on the surface of the concrete slab. Once a heavy or overweight vehicle runs over, it will cause the slab to break. Phenomenon, if the rolling is continued, the good concrete slab will also break and continue to extend, causing devastating damage, so repairing the broken slab in time without affecting the normal traffic is the first issue that the operating unit and the construction unit must consider, so At present, people's common practice is to remove all the concrete slabs at the fracture, and then re-construct, which is labor-intensive and time-consuming, a...
