Quality defect repairing method for concrete hollow floor
The invention relates to a quality defect repairing method for a concrete hollow floor, and belongs to the field of civil engineering. The method is mainly used for treating the quality defect of concrete of the lower plate of the hollow floor, and comprises the following steps of: pouring high-strength and self-compacting grouting material at high pressure from the bottom of the lower plate of the hollow floor by adopting a mode of connecting a grouting machine with a grouting pipe; and when the grouting material flows out of the exhaust pipe, the quality defect of the concrete of the lower plate of the hollow floor is repaired. According to the method, on one hand, it can be guaranteed that quality repair of concrete of the lower plate of the hollow floor meets the quality requirement, on the other hand, the defect that concrete cannot be poured from the upper portion of the hollow floor can be overcome, and the problems of insufficient strength and insufficient compactness caused by plastering and pressing mortar and other materials from the lower plate of the hollow floor can be solved. According to the method, the concrete quality defects of the lower plate of the hollow floor can be repaired most economically with minimum destructiveness.
本发明涉及一种混凝土空心楼盖质量缺陷修复方法，属于土木工程领域。该方法主要针对空心楼盖下部板混凝土存在质量缺陷进行处理，处理方法是：从空心楼盖下部板底部采用灌浆机与注浆管相连的方式，将高强、自密实的注浆料高压灌入，待注浆料从排气管流出则达到修复空心楼盖下部板混凝土质量缺陷的方法。此方法一方面可以保证空心楼盖下部板混凝土质量修复达到质量要求，另一方面可以解决无法从空心楼盖上部进行浇注混凝土的缺点，还可以解决从空心楼盖下部板抹压砂浆等材料造成的强度不足及密实度不够的问题。本发明能够最经济且破坏性最小的将空心楼盖下部板混凝土质量缺陷进行修复。
