A cutting and grouting device for wall crack repair

Abstract

The invention provides a cutting and grouting device used for repairing wall surface cracks. The cutting and grouting device comprises an air pump, a grouting tank, a vacuum tank, a motor, a controller and a grouting head. The grouting head comprises a drill bit and a dust collection grouting portion, wherein the drill bit is arranged at one end of the dust collection grouting portion and connected with the motor through a soft shaft. The dust collection grouting portion comprises a grouting cavity and a dust collection cavity. Grouting holes and a dust collection hole are formed in the connecting end surface of the dust collection grouting portion and the grouting head, wherein the grouting holes are in communication with the grouting cavity, and the dust collection hole is in communication with the dust collection cavity. The other end of the grouting cavity is connected with the grouting tank through a grouting pipe. The other end of the dust collection cavity is connected with thevacuum dust collection tank through a dust collection pipe. The air pump is provided with two air inlets and two air outlets, wherein magnetic valves are arranged on the two air inlets and the two airoutlets correspondingly. One of the air inlets is connected to the vacuum dust collection tank, and the other air outlet is connected to the grouting tank. The controller is correspondingly and independently connected with all the magnetic valves, and the controller is connected with the motor.

Description

technical field [0001] The invention relates to the construction field, in particular to a cutting and grouting device for repairing wall cracks. Background technique [0002] Chemical grouting is an important means of repairing concrete cracks, and has been widely used in crack repairing, mainly for repairing deep and penetrating cracks. Grouting is to prepare a certain material into a slurry, and use pressure equipment to pour it into the gap or cavity to make it fill, diffuse, gel, and solidify, so as to achieve the purpose of anti-seepage and reinforcement. [0003] In the prior art, the technological process is as follows: Drilling—clearing holes—burying grouting nails (grouting nozzles)—sealing surface sealing—leakage testing—grouting—removing grouting nails—sealing holes—checking the effect after grouting— Seam treatment. Among them, the steps of burying the grouting nails are relatively cumbersome. After drilling, the high-pressure air generated by the air compress...
