The invention discloses manufacturing equipment and a preparation method of a sintering-free rail transit sludge sponge stone filter material, the manufacturing equipment comprises a squeezing assembly arranged on a workbench, a flow guide assembly is arranged on the outer wall of the squeezing assembly, and supporting columns are fixedly arranged at the positions, close to the end corners, of the top of the workbench; the top of the supporting column is fixedly connected with a supporting plate, the top of the supporting plate is provided with an electric push rod extending to the bottom of the supporting plate, and an output shaft of the electric push rod is connected with a pressing plate. The preparation method comprises the steps that the squeezing assembly can adjust the overlapping degree of flow guide holes in the side walls of the first box body and the second box body, and therefore the sludge filtering degree of the flow guide holes in the squeezing process is adjusted; and after adjustment is comp
