Background
When the construction of the floor, the shear wall and other parts in the construction process of the structure at the present stage is performed, the sleeve is leaked and buried or the hole needs to be added at the later stage due to design change and process, the traditional method is to drill holes by using water, the sleeve is put into the holes after the holes are formed, and the mould-hanging mortar plugging is performed after the pipeline installation is completed, and the concrete steps are as follows:
1. the method comprises the steps of roughening the wall of a hole, cleaning up garbage and dust, then washing with clean water, wetting for more than 24 hours, then supporting a mold or hanging the mold, washing with clean water after supporting the mold, then pouring fine stone concrete (mixed with an expanding agent) with the grade higher than that of floor concrete, pouring 1/2 with the height being equal to the thickness of the floor, tamping and leveling (not capable of polishing), and then paying attention to regular watering and maintenance.
2. And (3) removing the template after 48 hours of primary plugging, filling the formed pits with water for a test, and performing secondary plugging if no water leakage or small water seepage exists after 24 hours.
3. Before the secondary plugging and pouring, brushing a layer of plain cement slurry doped with waterproof glue at the bottom and the periphery of the pit, then pouring fine stone concrete which is higher than the grade of the floor concrete by one grade, and after the pouring, the fine stone concrete is lower than the floor by one centimeter.
4. After the second hole plugging is finished, water injection test can be carried out one day, and after two days, if leakage does not occur, the hole plugging is finished, the upper surface and the lower surface of the hole are smoothed and polished, and then the next procedure is carried out for construction.
5/if the leakage amount of test water is large after the first hole plugging or the leakage occurs after the second hole plugging, all the hole plugging concrete is chiseled, and the hole is plugged by a formwork again until the leakage does not occur.
Therefore, the traditional casing pipe plugging method has multiple working procedures and long duration, the plugging effect is uneven by the operation level of workers, and the leakage is easy to occur.
