[0002] Concrete pouring is often used in bridge construction. Concrete pouring refers to the process of pouring concrete into a mold until it is plasticized. In civil engineering, concrete and other materials are put into a mold to form a predetermined shape. When pouring concrete, the free height of the concrete is generally not more than 2m. In the process of concrete pouring, bubbles often occur, resulting in large and small pits and pockmarks on the surface of the concrete after the mold is removed. This is extremely unsightly and seriously affects the appearance quality; and these bubbles will affect the strength of the concrete after the concrete is finalized, and it is easy to cause cracks or even fractures in the concrete. Therefore, how to remove bubbles in the concrete before the concrete is finalized is very important to ensure the quality of the concrete after pouring.

[0003] In the prior art, a vibrator or a vibrating rod is generally used to remove bubbles from concrete. This method has high requirements on manpower and equipment. Insufficient vibration time, insufficient vibration, and insufficient vibration speed will affect the elimination of bubbles. This method is troublesome to construct and the vibration effect is not ideal.
