Roughen the base surface to be grouting to remove dust and oil. Pre-wet the base surface before grouting and soak it with water until it is saturated. S2. Reserve an appropriate gap between the bottom surface of the support and the base surface for grouting; S3. Calculate the amount of powder and water based on the construction pouring volume.

The staff only needs to hold the armrest, which reduces the staff's holding strength of the grouting pipe and is conducive to improving the grouting efficiency.

[0016] 2. The present invention is provided with a partition and a bag-breaking knife. When the staff puts the powder bag into the inner cavity of the processing box from the opening, the baffle is closed first, and the bag-breaking knife is used to break it open during the downward sliding process of the powder bag, so that the powder in the powder bag can be discharged and pass through the discharge mesh plate and fall into the inner cavity of the arc-shaped fixed seat. The hydraulic push rod drives the push plate to move back and forth horizontally, which can drive the movable plate to shake back and forth, so that the powder in the powder bag can be fully poured out. The cam is driven to rotate by the driving motor, and the ball is pushed to move back and forth horizontally, which can further The discharge mesh plate is knocked and vibrated to speed up the discharge rate. When the discharge is completed, the movable plate can be flipped downward to drop the powder bag and collect it into the collection box. Then, the driving motor is used to drive the conveyor belt to rotate, and drive several trapezoidal plates to rotate in a circle, so that the powder in the inner cavity of the arc-shaped fixed seat can be pushed upward, and sent into the mixing box through the first slot and the second slot to be mixed with water. This effectively avoids the leakage pollution of powder bags during the crushing process and the adverse effects on human health, and at the same time, improves the convenience of loading.
