Description

Technical Field

[0001] The utility model relates to the technical field of concrete cracks, in particular to a grouting device for self-repairing concrete cracks. Background Art

[0002] Concrete components are widely used in the field of civil engineering due to their high strength, easy material acquisition, strong moldability and good integrity. However, concrete is a typical porous brittle material. Affected by adverse factors such as temperature changes, corrosion and aging, the accumulated damage inside the components under long-term loads will inevitably breed cracks of various widths, reducing the mechanical properties of the components while threatening the durability of the structure. When cracks occur in concrete, grouting is generally used to repair them.

[0003] After searching, the patent with application number CN202222609104.5 discloses a grouting device for self-repairing of concrete cracks. By injecting slurry and waiting for the slurry to adhere and solidify, the self-repair of the cracks can be achieved. During the grouting process, some grouting gaps are winding, and traditional grouting elbows are made of metal or straight pipes, which are not easy to directly insert. Some gaps are deeper and the grouting time is longer. Traditional grouting uses hand-held grouting equipment by staff. Holding the equipment for a long time will cause arm pain and shaking, and the grouting position will be constantly changed. At the same time, some gaps have a lot of dust inside. After direct grouting, the dust will affect the grouting effect. For this reason, a grouting device for self-repairing of concrete cracks is proposed. Utility Model Content
