The utility model discloses a core-taking anti-rotation base for simulating a cavity, which comprises a base body, the lower end of the base body is provided with a connecting portion, the lower end of the connecting portion is provided with a downwardly opening slot, and the upper end of the base body is provided with a permeable The lower end of the infiltration port is connected to the first pipe extending downward, the end of the first pipe is connected to the second horizontal pipe, and the second pipe is connected to the outlet opened on the side of the connecting part; A water tank, a plurality of permeable tanks are connected with the permeation opening; and a plurality of permeable waters are distributed divergently on the upper surface of the seat body with the permeation opening as the center. The whole rock sample seat adopts the design of large upper diameter and small lower diameter, which realizes variable diameter and compact structure. A pin hole is set on the telescopic rod of the connecting part and the bottom oil cylinder, and the centering pin is inserted into the pin hole for cooperation, so as to increase the frictional resistance of the contact part with the bottom oil cylinder piston rod, so that the structure is stable. achieve anti-rotation effect. |
