A complete set of grouting device and method for non-invasive repair of concrete cracks

technical field

The invention relates to the technical field of polymer grouting repair in geotechnical engineering, in particular to a complete set of grouting device and method for non-invasive repair of concrete cracks.

Background technique

Concrete structure is the most widely used structure in civil engineering, and now my country's annual construction consumption of concrete accounts for about half of the world's total. However, under the influence of various factors such as improper construction and pouring, too little steel reinforcement, concrete shrinkage and aging, and overweight loads, cracks usually appear in concrete structures. The existence of cracks will cause substances such as water vapor, acid, and alkali to penetrate into the structure, causing destructive damage to the structure such as steel bar corrosion and concrete peeling, and affecting the appearance of the building and the bearing capacity and service life of the concrete structure. Structure crack repair work.

At present, in the repair work of concrete cracks, the commonly used methods include surface repair method, surface grouting repair method and perforated grouting method. The surface repair method is to apply material on the surface of the crack to seal the crack opening, thereby isolating the internal contact with the outside world. This method can prevent the infiltration of water vapor to a certain extent in the early stage. As time goes by, the surface material substance gradually ages and the protection ability The surface grouting repair method is to use pressure feeding equipment to press the repairing grout into the crack from the crack surface with a relatively large pressure. Due to the complexity of the internal structure of the crack, it can only be pressed into the crack The shallow depth cannot completely fill the cracks, so it is impossible to fundamentally solve the problem of cracks, and sometimes due to excessive pressure, it will cause secondary damage to the cracks and further damage the structural safety. The application number is 201922275707.4. driller. The perforated grouting method is to drill holes obliquely from both sides of the crack to the crack, and then perform grouting. However, this method has relatively large disadvantages. It is impossible to accurately judge whether the hole is drilled into the crack, so it often leads to over-drilling, which causes secondary damage to the structure. Therefore, accurate and compact complete repair of cracks is very important to the safety characteristics of concrete structures.

The concrete crack non-invasive repair grouting set according to any one of claims 1-4, characterized in that the concrete crack non-invasive repair grouting set further comprises a grouting device (6), the grouting device (6) comprises a slurry tank (61), a feed pipe (62) and a grouting pipe (63), an outlet of the slurry tank (61) is connected with one end of the feed pipe (62), the other end of the feed pipe (62) is butted with the grouting pipe (63) through a reducer (64), and the grouting pipe (63) is used for grouting a grouting hole (5).

9. A method of repairing a concrete crack non-invasive repair grouting set according to any one of claims 1-8, comprising the steps of:

step S1: detecting the width and the depth of the crack by adopting a crack detector, calculating the volume of the crack in a segmented manner at equal intervals, and selecting a drill rod (41) to be installed on the head of a drilling machine (4) according to the detected crack width data;

step S2: placing a drilling machine (4) at the upper part of the crack, carrying out position calibration to ensure that a drill rod (41) is positioned right above the crack, then starting the drilling machine (4), simultaneously starting a lifting device to drill downwards, and drilling a grouting hole (5);

and step S3: cleaning hole slag and crack periphery by adopting ethanol spirit, and then filling a grouting pipe (63) into a grouting hole (5);

and step S4: adding a repairing material into the grouting equipment (6), adjusting grouting pressure according to the detection data, starting the grouting equipment (6) to start grouting, removing the grouting guide pipe after grouting is finished when the amount of injected grout exceeds the calculation result, and cleaning the periphery of the opening of the grouting hole (5);

step S5: and repeating the steps, and performing grouting repair on the next crack section at a distance from the last grouting hole (5) until the non-invasive grouting repair of the whole crack is finally completed.

10. The method for repairing a grouting set for non-invasive repair of concrete cracks according to claim 9, wherein step S3 further comprises attaching a special transparent adhesive tape to the cracks around the grouting pipes.
