Borehole stressmeter installation rod and installation method thereof

The invention provides a borehole stressmeter installation rod and an installation method thereof. The installation rod comprises a rod body and an adjusting mechanism. The rod body comprises a plurality of sections of rod body units, wherein the head rod body unit is in matching connection with a borehole stressmeter through the adjusting mechanism; the adjacent rod body units are connected in sequence through a fixation mechanism; and the operation end of the adjusting mechanism extends out of the end portion of the tail rod body unit. The installation rod also comprises a calibration line provided with length scales and an angle measurement mechanism in matching installation with the calibration line. The calibration line is parallel with a central axis of the rod body; and after the installation rod is connected with the borehole stressmeter, the extension line of the calibration line passes through a pressure measuring block of the borehole stressmeter. The reliable abutting of the plurality of sections of same-specification rod body units ensures work reliability of a transmission torque, and that the rod body cannot be separated from the borehole stressmeter due to repeated push and pull in the pushing process; and the method can provide more accurate borehole stressmeter arrival depth and installation angle.
