It is edge-on, make compass length of side abutting arrangement face, and stir with finger the monkey wrench outside chassis, while compass is moved along structural plane,
When bubble tube bubble is placed in the middle, the signified maximum number of degrees of deviational survey pointer are the true dip angle of structural plane.If clinometer is suspended type
Compass, method with it is upper essentially identical, be a difference in that finger pins the button outside chassis, suspending hammer then freely swings, when up to most
Finger is unclamped during big value, suspending hammer fixes the true dip angle that signified reading is structural plane.
Structural plane occurrence, which is measured, using existing mechanical compass method must all make universal level bubble or pipe
Shape bubble is placed in the middle, can accurately be measured.When compass level, it intersects with structural plane, and the intersection direction is
Structural plane is moved towards, and tendency is then floor projection azimuth of the face on structural plane incline direction using the intersection as method phase direction.
Measurement of dip angle is measured by the goniometer with bubble tube or suspended type clinometer.Ensureing sieve in being measured using mechanical compass
Ensure that bubble is placed in the middle while disk seamed edge abutting arrangement face, structural plane trend, tendency can be accurately measured, while also needing
Its inclination angle is measured by adjusting bubble tube or suspending hammer.This method is influenceed larger by measuring environment and human factor, measurement speed
Degree is slower.
