Embodiment 1
[0034] refer to Figure 1-2 , a multi-angle normal stress reaction frame device for simulating space, which includes a pressure bearing plate 1, a universal rotating wheel 4 is installed at the bottom center of the pressure bearing plate 1, and the adjacent two sides of the pressure bearing plate 1 An angle measuring instrument 5 is installed on the wall, a pressure steel plate 3 is installed on the top of the pressure bearing plate 1 through a threaded rod 2, a pressurized air cushion 6 is installed on the top of the pressure bearing plate 1, and the universal rotating wheel 4 A steel tripod 7 with a multi-stage telescopic structure is installed at the bottom of the bottom; the pressurized air cushion 6 is connected with a nitrogen cylinder 8 through a trachea, and provides high-pressure nitrogen. By adopting the reaction force frame device with the above structure to apply pressure to the rock mass through the threaded rod and the pressurized air cushion, and by adjusting th...
Embodiment 2
[0041] The method of using any one of the simulated space multi-angle normal stress reaction frame devices includes the following steps:
[0042] Step1: Install the universal rotating wheel 4 on the bottom of the pressure bearing plate 1, fix the steel foot frame 7 under the universal rotating wheel 4, and install screw rubber pads 11 on the bottom of the steel foot frame 7;
[0043] Step2: Adjust the main support rod and auxiliary support rod of the steel tripod 7, and then adjust the height of the bearing plate 1, and tighten the fixing bolt 9 to fix the height of the bearing plate 1;
[0044] Step3: Adjust the angular position of the pressure bearing plate 1 on the top of the steel tripod 7 by turning the universal rotating wheel 4;
[0045] Step4: Place the pressurized air cushion 6 in the middle of the top of the pressure plate 1;
[0046] Step5: Put the rock mass in the middle of the pressurized air cushion 6, insert the small holes around the pressure plate 1 with the ...
