The invention discloses a multi-pore high-strength sintering permeable floor brick. The multi-pore high-strength sintering permeable floor brick is prepared from, by weight, 40-43 parts of sewage plant sludge, 6-7 parts of rice hulls, 4-5 parts of potassium feldspar powder, 10-12 parts of fly ash, 10-12 parts of water glass, 29-31 parts of basalt rubble, 5-6 parts of sawdust, 9-11 parts of mesoporous silica, 0.8-1 part of a silane coupling agent kh560, 3-4 parts of polyvinyl alcohol fibers, 7-9 parts of blast furnace slag and 2-3 parts of chemical waste gypsum powder. According to the multi-pore high-strength sintering permeable floor brick, the mesoporous silica, the sawdust and the polyvinyl alcohol fibers are added in preparation of the brick, and a composite through hole structure can be formed through sintering molding after technological modification; in addition, multiple pores distributed densely are obtained by reasonably regulating the particle size of mixed aggregates; meanwhile, the product is high in compressive strength, firm, durable and high in permeable coefficient.
