Anchoring type concrete crack repairing method

MEI DANDAN

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.

本发明公开了一种锚固式混凝土裂缝修补方法，属于混凝土裂缝修补技术领域，通过在开凿成Y型槽的裂缝位置内壁上锚固多个锚固球，并在Y型槽内底部插设T型锚固钉，向Y型槽内注入具有一定温度的修补料,修补料与T型锚固顶以及多个锚固球相融合粘接，锚固球受热后，其内部的粘结剂溢出，粘结剂采用熔融且具有粘结性的树脂材料，修补料导入至锚固槽内并与粘结剂相融合，粘结剂充当修补料与锚固球以及锚固孔之间锚定的粘合材料，有效提高锚固球于锚固孔内侧的锚定效果，而修补料在粘结剂的配合作用下能够与锚固球充分粘接固定，在一定程度上有效提高修补料与Y型槽修补界面的修补强度，不易使得该裂缝发生二次开裂。
