Abstract

The invention discloses a simulation space multi-angle normal stress reaction frame and a use method. The simulation space multi-angle normal stress reaction frame comprises a bearing plate, a universal rotating wheel is arranged at the bottom center location of the bearing plate, angle measuring instruments are arranged two adjacent sidewalls of the bearing plate, compression steel plate is arranged at the top of the bearing plate through the support of the threaded rod, a compression air cushion is arranged at the top of the bearing plate, and a steel footpad with the multi-level telescopicstructure is arranged at the bottom of the universal rotating wheel; the compression air cushion is connected with a nitrogen gas cylinder through the air pipe so as to provide the high-pressure nitrogen. The device exerts the pressure on the rock through the threaded rod, the space multi-angle force condition of the rock can be simulated by adjusting the universal rotating wheel and the stretching length of the steel footpad.

Description

technical field [0001] The invention relates to a multi-angle normal stress reaction frame device for simulating space and a use method thereof, belonging to the field of rock mass test devices. Background technique [0002] With the decrease of shallow resources, entering deep mining has become an inevitable trend of mining resources at home and abroad. In the prior art, the invention patent with the patent number 201110232394 discloses a "Visual test device for crack grouting under complex conditions" and a utility model named "Visual seepage test device for rock crack seepage simulation experiment" The patent can conduct fracture seepage experiments, but it can only conduct simple horizontal angle experiments, or the simulated angles are not accurate enough, or it is not a real multi-angle simulated space. However, in tunnel excavation, deep foundation pit excavation, mining and other mining projects involving deep rock mass, the stress of rock in multiple angles in spac...
