④ When the embedded part, the water stop steel plate and the steel bars are dense, the round head steel pipe rod is used for assisting in manual tamping. The vibration should be carried out along with the blanking progress in a uniform and orderly way, and the vibration can not be leaked or excessively vibrated.

⑧ In the weather of high temperature or windy weather, the water on the concrete surface is lost, irregular cracks are formed on the surface near the initial setting, and the irregular cracks are eliminated by a polishing machine or manual pressing. After the treatment, the moisture should be prevented from evaporating continuously to shrink the concrete surface, and the moisture preservation maintenance should be performed in time.

⑨ When the concrete is poured, the concrete at other parts is strictly prevented from entering the expanded post-pouring zone, so that the setting effect is not influenced. The wet pipe mortar before pouring the concrete must be discarded, the pipe is folded, the fault is removed or other reasons cause the discarded concrete to be strictly forbidden to enter the working surface. The concrete is strictly forbidden to scatter on the part which is not poured, so that potential cold joints are avoided.

⑩ The elevation control of the concrete slab surface adopts the steps of setting the standard ribs every 2m for leveling, and leveling the floor surface by using a laser level gauge for control.

After the concrete is poured, the concrete should be highly paid attention to moisture preservation and maintenance for 7-14d, after the plane structure is flattened, water should be sprayed and wetted, and then the concrete is tightly covered by a plastic film, so that the relative humidity of the environment is kept above 80% by spraying mist water in the maintenance period, and the dry shrinkage of the concrete is reduced. The vertical structure adopts a brush hydrophilic curing liquid to seal and cure, and a piece of color stripe cloth is additionally arranged on the outer wall to carry out full-closed heat storage curing.
