The invention discloses high-water-permeability concrete water-permeable ground tiles. The high-water-permeability concrete water-permeable ground tiles are prepared from the following raw materials in parts by weight: 120-150 parts of a main material, 2-10 parts of glutinous rice flour, 1-6 parts of gypsum, 1-2 parts of magnesium carbonate, 20-40 parts of regenerated rubber powder, 60-100 parts of blast furnace slag, 1-2 parts of aluminum powder, 6-10 parts of fly ash, 3-8 parts of sepiolite powder, 1-6 parts of mica powder, 4-10 parts of basalt fiber, 2-9 parts of heavy calcium carbonate, 1-4 parts of microcrystalline cellulose, 1-2 parts of polydimethylsiloxane, 1-2 parts of tartaric acid, 1-2 parts of a water-reducing agent, and 100-200 parts of water. A carbon nanotube composite is prepared by adopting a technology comprising the following steps of uniformly mixing urea, formaldehyde and water, adjusting the pH value of the system to 8.6-8.9, and carrying out heating with stirring; adding lecithin, carbon nanotubes and N,N-dimethyl-formamide, and carrying out uniform stirring; and then, adding polypropylene, and carrying out stirring so as to obtain the carbon nanotube composite.
