The detailed introduction of the anti wave block mold is based on the experience and technical summary of this kind of formwork processing. Because the shape of the anti wave block is not fixed, the common ones are octagonal, tetragonal and so on. It needs to be processed with full reference to the drawings of the concrete anti wave block, so it is all determined according to the fabrication style of the steel formwork. The use of anti wave block is concentrated in coastal areas, especially in the areas with more beach development. Its main function is to buffer the waves and protect the coastal ecological balance. Therefore, the volume of general concrete anti wave block is relatively large, and the concrete bearing gravity is relatively large, so the requirements for formwork processing are very strict.
