The invention discloses a sintered water-permeable ground tile with rare earth tailings added. The ground tile is prepared from, by weight, 40-43 parts of sludge from a sewage plant, 6-7 parts of rice husks, 4-5 parts of potassium feldspar powder, 10-12 parts of coal ash, 10-12 parts of water glass, 30-33 parts of rare earth secondary tailings, 13-15 parts of black talc, 13-14 parts of river sand, 2-3 parts of sodium carbonate, 4-5 parts of water-based fluorine-carbon emulsion, 2-3 parts of pulp mill waste liquid and 5-7 parts of kaolin. According to the sintered water-permeable ground tile, the rare earth secondary tailings are adopted, aggregate such as the kaolin and the river sand and caking elements such as the water glass are further combined for preparing a tile body high in strength, elements such as the sodium carbonate and the pulp mill waste liquid are further added, through sintering, the tile body is made to be more compact, the strength is further improved, meanwhile, communicated pores can be generated, the good water permeation efficacy is achieved, by means of the ground tile, recycling of waste resources can be achieved, energy is saved, environmental protection is achieved, cost is low, and the process is convenient to control industrially.
