Space-situ rock joint surface plate and the lower plate relative deformation measuring device
2013
Generating space relative deformation measuring apparatus according to the present invention relates to a method for monitoring the field of in-situ rock joint plane and the lower disc on the disc space relative movement occurs. Measuring device consists of a fixed rod, the fixing bolt, the telescopic rod, fixed to the adjusting bolt, the adjusting lever, the connector housing, the locking bolt, the fixing bar, the fixing bolt, the telescopic rod, fixed adjusting screw, the adjusting lever, the connecting seat, the lock bolt, the lever displacement measuring method, stretching the spring, the outer sleeve, the balls, caps, assembled with the support rod and a dial made. Means are fixed by the fixing rod and the lower fixing rod jointed face plate rocks and the lower plate rocks, and the displacement of the measuring rod telescopic achieve displacement measurement normal by France, the lever toward the deformation measured by the method of the lower end of the head on the dial mobile achieved plane deformation measurements, enabling measurement of the relative deformation of the space between the upper and lower plate joints, rock has the advantage of direct access to the disc space and the disc section cleavage plane relative deformation value.
