The invention discloses a self-damage concrete crack repairing process, belongs to the technical field of concrete construction, and aims to embed an appropriate multi-section type embedded repairingrod at a concrete crack and repair the concrete crack; by injecting repairing liquid into the multi-section type embedded repairing rod, the elastic sponge block in the hollow self-damage block absorbs part of water in the repair liquid and transfers the water to the disintegration microspheres, and the disintegration microspheres have a violent disintegration reaction, so that on one hand, the wall grabbing self-damage needle is driven to vibrate at high frequency to impact the inner side wall of the crack; on the other hand, the liquid storage ball bag is forced to release stored dilute sulfuric acid through the wall grabbing self-damage needle under the extrusion action to form damage to the inner side wall of the crack, and a plurality of damage holes distributed in a radial shape areformed in the inner side wall of the crack in cooperation with the impact action of the wall grabbing self-damage needle; after the crack is filled with the repairing liquid, the damaged part is repaired by matching with the wall grabbing self-damage needle to form a combination similar to a pre-embedded anchoring type, so that the overall repair strength of the crack is improved.
本发明公开了一种自损式混凝土裂缝修复工艺，属于混凝土施工技术领域，可以实现在混凝土裂缝处埋设合适的多节式内嵌修复棒，通过向多节式内嵌修复棒内注入修复液，通过中空自损块内的弹性海绵块吸收部分修复液内的水分并转移给崩解微球，崩解微球发生剧烈的崩解反应，一方面带动抓壁自损针高频震颤对裂缝内侧壁形成冲击，另一方面利用挤压作用迫使储液球囊通过抓壁自损针释放出储存的稀硫酸对裂缝内侧壁形成“损伤”，配合抓壁自损针的冲击作用在裂缝内侧壁上形成多个放射状分布的损伤孔，然后由修复液在填充裂缝之后，配合抓壁自损针对损伤部位进行修复，形成类似于预埋锚固式的结合，从而提高对裂缝的整体修复强度。
