Anti-corrosion structure of embankment slope

The invention is an anti-corrosion structure for bank slopes, especially an anti-corrosion structure with high structural strength, plasticity and water permeability that can be firmly attached to the surface of various slopes.

For common slope structures (such as embankments or mountain walls), in order to prevent rain, river or seawater erosion, the slope must be excavated with heavy machinery, and then a cement protective wall must be installed on the slope. However, the construction of the cement protective wall is very slow, the construction cost is high, and it takes a lot of manpower, and the design must be evaluated before the construction can be carried out. Therefore, the maintenance speed and efficiency of the bank slope are reduced.
