[0032] An anti-cracking layer 3 is installed above the protective layer 2. The anti-cracking layer 3 includes a three-dimensional steel grid 301 set through concrete above the corrosion-resistant coating 203.

[0038] The production process of three-dimensional finishing layer 502: that is, there are slight footprints when people step on it.
