s2, the screw rod penetrates through the upper pressing injection body, the building body and the lower pressing injection body, and the nut is screwed, so that the screw rod tightens the upper pressing injection body and the lower pressing injection body on two sides of the building body;
s3, pressing base liquid into a pressing and injecting cavity through a pressing and injecting pump by using a pressing and injecting port, penetrating the base liquid into the hard sponge through an injection hole in the cavity, uniformly pressing a floor slab through the hard sponge, enabling the base liquid to be pressed into a hole seam on the surface of a building body, after keeping a preset pressure for a certain time, finishing pressing and injecting, closing the pressing and injecting pump, loosening a nut, removing a screw rod, and releasing a pressing rod;
s4, manually pushing the upper pressing injection body and the lower pressing injection body to enable the roller to drive the upper pressing injection body and the lower pressing injection body to slide on the surface of the floor slab, and pressing and injecting the next position; s5, when the concrete wallboard is pressed and injected, the upper pressing injection body and the lower pressing injection body are lifted to move up and down through the movable lifting frame, the steps S2 and S3 are repeated, the pressing injection is completed, the height to be pressed and injected is adjusted through driving the movable lifting frame, and the concrete wallboard is pressed and injected.
