Anchoring type concrete crack repairing method

Abstract

The invention discloses an anchoring type concrete crack repairing method, and belongs to the technical field of concrete crack repairing. The method comprises the following steps that a plurality ofanchoring balls are anchored on the inner wall of a crack position dug into a Y-shaped groove, a T-shaped anchoring nail is inserted at the bottom in the Y-shaped groove, a repairing material with a certain temperature is injected into the Y-shaped groove, the repairing material is fused and bonded with the T-shaped anchoring nail and the plurality of anchoring balls, after the anchoring balls areheated, a binder in the anchoring balls overflows, the binder is a molten resin material with cohesiveness, the repairing material is guided into the anchoring groove and fused with the binder, and the binder is used as a bonding material for anchoring between the repairing material and the anchoring balls and anchoring holes. The anchoring effect of the anchoring balls on the inner sides of theanchoring holes is effectively improved, the repairing material can be fully bonded and fixed to the anchoring balls under the matching effect of the binder, the repairing strength of the repairing material and the Y-shaped groove repairing interface is effectively improved to a certain degree, and secondary cracking of the crack is not likely to happen.

Description

technical field [0001] The invention relates to the technical field of concrete crack repair, and more specifically, relates to an anchored concrete crack repair method. Background technique [0002] In recent years, with the continuous development of building waterproof technology and the continuous improvement of my country's building waterproof standards, regulations, etc., the leakage rate of my country's housing construction has continued to decline, and the nationwide and large-scale leakage problems have been initially contained, but underground The leakage problem of the building is still not optimistic. [0003] There are many reasons for the formation of concrete cracks, which can be roughly divided into two categories: one is the cracks caused by the action of load, which is called load cracks. There are two main types of cracks under load: direct cracks and secondary stress cracks. The direct crack refers to the crack caused by the direct stress generated by the...

Problems solved by technology

The disadvantage of these methods is that the control and expansion of the cracks can not play a substantial role in restraint, only the concrete cracks are closed, healed and filled, and the repair interface is a weak node in the concrete crack repair process, and the repair material is not easy to mix with The end face of the crack is bonded with high strength, and the repair strength is lacking. One crack may become two cracks, and the crack problem cannot be completely solved.
