Description

Technical Field

[0001] The utility model relates to the technical field of concrete crack repairing, in particular to a concrete crack repairing device. Background Art

[0002] During the construction process, cracks may appear on walls or roads due to collisions or unpredictable factors such as hail or collisions with heavy objects. In order to repair the cracks, a concrete crack repair device can be used to pour concrete slurry into the cracks to repair the cracks and provide repair protection for the walls and roads.

[0003] After searching, a concrete crack repair device and a concrete crack repair method with a publication number of CN111561173A are found. The concrete crack repair device and the concrete crack repair method relate to the technical field of concrete construction. The concrete crack repair device comprises a protective shell and a water absorbing member; the water absorbing member is arranged inside the protective shell; an opening is arranged on the protective shell; the water absorbing member is used to carry the repair slurry, and the water absorbing member is used to cover the crack position of the concrete at the opening. The construction personnel place the water absorbing member in the protective shell, and then pour the repair slurry on the water absorbing member, so that the water absorbing member carries enough repair slurry, and then covers the opening of the protective shell at the crack position, and the water absorbing member abuts against the crack position of the concrete from the opening, so that the repair slurry absorbed by itself penetrates into the crack. The concrete crack repair device has the following problems:

[0004] Generally, the concrete crack repair device mostly uses telescopic rods to provide support for the protective shell and change the repair height. Since multiple telescopic rods are provided at the bottom of the protective shell to provide support, when adjusting the height of the protective shell, if a single telescopic rod is adjusted one by one, it will take a lot of time;

[0005] The repair slurry inside the protective shell accumulates at the bottom for a long time and is prone to sedimentation and aggregation, which will affect the discharge of the repair slurry and the efficiency of pouring into the gaps.

[0006] In view of the above problems, we propose a concrete crack repairing device. Utility Model Content
