The invention relates to the technical field of geotechnical engineering sampling, in particular to a soil-rock mixture stratified sampling device for geotechnical engineering. A soil-rock aggregate stratified sampling device for geotechnical engineering comprises a support, a mounting plate is slidably connected in the support, first driving parts fixedly connected with the mounting plate are symmetrically mounted in the support, the mounting plate is slidably connected with a positioning frame, a second driving part is mounted on the positioning frame, the positioning frame is slidably connected with a tensioning assembly, and the mounting plate is rotatably connected with a mounting frame. And a first driven shaft is slidably connected in the mounting frame. A moving block moves downwards to drive a toothed plate to drive a transmission gear to be matched with a rack, so that a first driven shaft and a second driven shaft drive a storage shell to be close to the inner wall of a drill hole, the first driven
