AI Technical Summary
The concrete pool walls of sewage pools are susceptible to corrosive media, resulting in structural damage and leakage, and the prior art is difficult to effectively prevent this problem.
A double-layer protective structure is adopted, including a rubber asphalt layer on the surface of the concrete layer of the sewage pool, and an inner anticorrosion layer, an adhesive layer, a protective layer and an outer anticorrosion layer are laid on its surface. Through the combination of these layers, the anticorrosion performance of the concrete layer is improved.
Through the double-layer protection of the internal and external anti-corrosion layer, the anti-corrosion performance and service life of the sewage pool concrete layer is significantly improved. The design of the protective layer can continue to protect the internal anti-corrosion layer when the external anti-corrosion layer is damaged, ensuring the sustainability of the anti-corrosion effect.
