The invention provides a three-dimensional grouting diffusion mechanism test device and test method. The test device comprises a grouting machine, a grout inlet pipe, a test cavity, a grout outlet pipe and a data acquisition instrument, wherein a grout inlet cover plate and a grout outlet cover plate are respectively arranged at two ends of the test cavity; the grout inlet pipe passes through thegrout inlet cover plate and extends into the test cavity; the test cavity is filled with a test material, and the test material is a material to be grouted; the grouting machine is communicated with the grout inlet pipe and can inject grout into the test cavity; a plurality of temperature measuring points are arranged in the test cavity, and a temperature measuring device is arranged on each temperature measuring point. The test method using the test device can simulate grouting and generate a three-dimensional graph, and the diffusion condition and the diffusion dynamic process of the grout are obtained. 本发明提供一种三维注浆扩
