Device and method for manufacturing hidden non-through jointed rock sample

The invention discloses a device and a method for manufacturing a hidden non-through jointed rock sample. A metal rod, an ice groove mold, a mica sheet and the like are adopted to manufacture a pouring mold of a non-through joint rock sample, an ice groove is manufactured through freezing, the mica sheet is supported to simulate the non-through joint of the rock, and the current intensity is controlled; the electromagnetic induction of the electromagnetic coil is utilized to enable the thin metal bar with scales to rotate to drive the icing groove and the mica sheet to rotate to different degrees, joints at different angles in the rock are accurately simulated, then the prepared concrete rock material is poured into the mold, and the concrete rock material is solidified by utilizing the hydration heat release of the concrete rock material in the solidification process. The ice-made groove is heated and melted, mica sheets are only left in the rock sample, and finally the hidden non-through joint rock sample i
