Description

Technical Field

[0001] The utility model relates to a concrete structure crack grouting repair device, belonging to the technical field of building construction. Background Art

[0002] During the use of concrete building components, cracks may occur due to external forces. If these cracks are not repaired in time, they may accelerate the aging of the concrete structure, reduce its bearing capacity, and even cause the risk of structural collapse, resulting in damage to the overall project quality. Therefore, it is particularly important to repair cracks in concrete structures in a timely manner.

[0003] At present, a grouting device is usually used to inject repair slurry into the cracks to complete the repair of the cracks. However, it is difficult to measure the depth and length of cracks in concrete structures, and it is difficult to accurately determine the amount of repair slurry required to repair the cracks in concrete structures. Therefore, when the existing grouting device is used, the amount of repair slurry usually exceeds the actual amount required in the storage barrel. In order to avoid pollution, the excess repair slurry cannot be directly poured back into the storage barrel for recycling, resulting in a certain amount of waste.

[0004] A Chinese utility model patent with publication number CN203684723U discloses a concrete crack repairing device, including a slurry storage barrel, a piston and a push rod. The piston is arranged in the slurry storage barrel, and the push rod is connected to the piston. The push rod is a screw-like structure with a thread on the surface; a barrel cover is fixed to the rear end of the slurry storage barrel, and a hole for the push rod to pass through is provided in the center of the barrel cover; a connecting head is provided at the front end of the slurry storage barrel, and a slurry outlet nozzle protruding outward is provided in the connecting head. The slurry outlet nozzle is connected to the interior of the slurry storage barrel, and the connecting head is connected to the grouting nozzle through a thread provided on its inner wall, and the grouting nozzle is butt-jointed with the slurry outlet nozzle.

[0005] The above-mentioned reference example needs to store the repair slurry in a slurry storage tube in advance when in use. In order to avoid insufficient repair slurry in the slurry storage tube, a sufficient amount of repair slurry needs to be stored in the grouting device, which may easily cause waste of repair slurry. At the same time, the above-mentioned reference example is not easy to maintain stability during use, which may cause the repair slurry to deviate from the cracks and cause waste. Therefore, improvement is urgently needed. Utility Model Content
