Blast walls can effectively resist flood impacts through their unique structural design. The high-strength steel wire mesh box of the blast wall and the filling when forming a strong wall, can disperse and absorb the impact of flood water. At the same time, the flood wall has good water permeability, reducing the water pressure and ensuring the stability of the wall. The structure is not only safe and reliable but also adaptable. blast walls can play a good role in flood control in complex hydrological environments.
