Three-dimensional permeation grouting simulation test device

The utility model discloses a three-dimensional permeation grouting simulation test device which comprises a slurry supply unit and a three-dimensional grouting test bed. The three-dimensional grouting test bed is used for placing a test sand sample, and an osmotic pressure sensor is pre-embedded in the test sand sample; the osmotic pressure sensor is connected with the data acquisition device; the slurry supply unit is composed of a control system, a hydraulic station, a hydraulic jack, a support, a steel piston and a slurry storage barrel. The slurry storage barrel is installed in the support, the hydraulic jack is installed on the support, and the power output end of the hydraulic jack is connected with the steel piston, so that slurry in the slurry storage barrel enters the three-dimensional grouting test bed; the slurry storage barrel is communicated with the interior of the three-dimensional grouting test bed through a grouting pipe; the control system controls the hydraulic jack to move. 本实用新型公开了一种三维渗透
