[0002] The airbag for prefabricated hollow slabs of bridges is an inflatable and deflated cylindrical bag used to form the cavity of concrete components. When manufacturing hollow components, a bridge core mold is placed in the middle and filled with compressed air. After the concrete solidifies, the compressed air in the bag is released, the bridge core mold contracts, and the bridge core mold can be pulled out of the cavity. Construction practice has proved that the use of the bridge core mold hole-forming process is convenient to construct, has a wide range of applications, can be reused more than 80-100 times, and can reduce construction costs.

[0003] In the prior art, when the bridge core mold needs to be pre-cured after use, the surface of the bridge core mold is first rinsed with clean water, and the cement adhered to the surface of the bridge core mold is cleaned with tools such as wooden boards.
