High-strength tunnel residue soil brick and preparation method thereof

The invention discloses a high-strength tunnel residual mud residue soil brick and a preparation method thereof. The high-strength tunnel residual mud residue soil brick is prepared from the following raw materials in parts by mass: 30 to 80 parts of tunnel residual mud residue soil, 15 to 20 parts of cement, 10 to 15 parts of water and 0.01 to 0.03 part of fiber. Wherein the fibers comprise polypropylene fibers, and the tunnel mud residue soil comprises at least one of quartz and kaolin. According to the invention, the high-strength residual mud slag brick is prepared by taking the tunnel residual mud slag generated by tunnel engineering as a main raw material, adding cement, fiber and the like and carrying out one-time compression molding, so that the comprehensive utilization rate and the additional value of the tunnel residual mud slag are improved, and a way is provided for resource utilization of the tunnel residual mud slag; and the method has important significance on resource recycling. 本发明公开了一种高强隧道余
