Sample preparation mold for static compaction cutting ring sample

The utility model relates to the field of soil sample tests. The utility model relates to a die, in particular to a sample preparation die for a static compaction cutting ring sample. The device comprises bases which are connected in sequence, a retaining ring and a sample pressing cylinder, the device is characterized in that the protection ring is installed on the base, the sample pressing cylinder is installed in a second-stage groove of the protection ring, the protection ring inner cylinder is filled with a cutting ring through an auxiliary cushion block, in the soil sample filling state,soil placed in the sample pressing cylinder is extruded through the sample pressing piston, in the demolding state, the base is disassembled, and the cutting ring and a soil sample are demolded through the demolding piston. The cutting ring sample preparation mold is simple in structure and high in operability, soil sample particles can uniformly and completely enter the cutting ring, and it is guaranteed that the cuttin
