Grouting repair method for concrete cracks

Abstract

The invention relates to a grouting repair method for concrete cracks, and the method mainly used for repairing the concrete cracks through grouting. According to the method, the grouting liquid filling degree can be observed and judged, and the repair quality of the concrete cracks is ensured. In the method, an X-ray machine, a computer, a detection agent, grouting equipment and grouting liquid are mainly included. The working principle is as follows: the grouting equipment is used for pressing the detection agent in the concrete cracks, the X-ray machine is used for irradiating the concrete cracks, a crack distribution map is displayed on a display screen of the computer, a crack striograph A is formed, the grouting equipment is used for pressing the grouting liquid in the concrete cracks, meanwhile the X-ray machine is used for irradiating the concrete cracks, a striograph B is displayed on the display screen of the computer, working personnel compares the crack striograph A and the striograph B, if the striograph B can completely cover the striograph A, it shows that the concrete cracks are filled with the grouting liquid, and if the striograph B can not completely cover the striograph A, grouting needs to be conducted continually until the concrete cracks are completely filled with the grouting liquid.

Description

technical field [0001] The invention is mainly used for grouting repair of concrete cracks. Background technique [0002] In the field of construction engineering, if there are cracks in the concrete structure and the cracks affect the safe use of the structure, then such cracks must be repaired. The current repair method is to use grouting equipment to inject grouting fluid into the concrete cracks. After the grouting fluid solidifies The concrete at the crack is repaired, but this method cannot observe whether the grouting fluid is completely filled with the concrete crack, and can only be judged by experience, which is likely to cause quality problems. Contents of the invention [0003] The present invention solves the above problems, it can observe and judge the filling degree of the grouting liquid, and guarantee the repair quality of concrete cracks; it mainly includes X-ray machine, computer, detection agent, grouting equipment, and grouting liquid; the detection ag...
