[0002] Cast-in-place structure is the mainstream construction method in the contemporary construction industry. It is achieved by building a steel cage in the formwork, pouring concrete into the interior, and filling the concrete through vibration. After the concrete solidifies, it is cast-in-place with the steel bars. It has the advantages of flexible construction and high sealing.
[0003] However, in actual use, holes may appear on the surface of the structure after pouring due to unqualified concrete solid ratio and insufficient vibration, which need to be repaired. By pouring over the holes, the concrete in the holes is solidified together with the existing pourings. In order to prevent the concrete from collapsing and falling, a formwork is needed to support the bottom. On the one hand, the bottom formwork is likely to affect the subsequent construction. On the other hand, directly pouring concrete has the problem of loose connection and easy falling after pouring. For this purpose, a device for repairing holes on the surface of a cast-in-place structure is specially provided. Utility Model Content
