Description
Technical Field
The invention relates to the technical field of geotechnical engineering high polymer grouting repair, in particular to a concrete crack non-invasive repair grouting complete device and method.
Background
The concrete structure is the most applied structure in civil engineering, and the consumption of concrete in the engineering construction of China accounts for half of the total amount of the world every year. However, cracks often appear in concrete structures under the influence of various factors such as improper construction pouring, too little steel bar preparation, concrete shrinkage aging, overweight load and the like. The existence of cracks can cause the infiltration of moisture, acid, alkali substances and the like into the structure, cause the destructive damage of the structure such as the corrosion of steel bars, the peeling of concrete and the like, and influence the appearance of buildings and the bearing capacity and service life of concrete structures, so that the crack repairing work is required for the concrete structures.
At present, in the repair work of concrete cracks, methods which are commonly adopted include a surface repair method, a surface mud jacking repair method and a punching and grouting method. The surface repairing method is to coat materials on the surfaces of cracks to seal the crack openings so as to isolate the interior from contacting with the outside, and the method can prevent water vapor from permeating to a certain extent at the early stage, surface materials are gradually aged along with the lapse of time, the protective capability is weakened, and the problem of cracks cannot be fundamentally solved; the surface grouting repair method adopts pressure feeding equipment to press repair slurry into a crack under a large pressure from the surface of the crack, and due to the complexity of the internal structure of the crack, the repair slurry can only be pressed into the crack at a shallow depth and cannot completely fill the crack, so that the problem of the crack cannot be fundamentally solved, and sometimes, the crack is secondarily damaged due to overlarge pressure, and the structure safety is further damaged, and the application number 201922275707.4 discloses a drilling machine for buildings. The punching and grouting method is characterized in that holes are obliquely punched to the crack from the two sides of the crack, and then grouting is performed, but the method has the disadvantages of large damage to the structure on one hand and incapability of accurately judging whether holes are drilled to the crack or not on the other hand, so that overtravel drilling is often caused, and secondary damage to the structure is often caused.
