Abstract
The utility model relates to a compass orientation device for longhole ground stress testing, comprising a protection tube, a compass, a timer and a guide tube, wherein the compass and the timer are arranged in the protection tube and fixed by set screws at the top of the timer, and the protection tube is arranged in the guide tube. The compass orientation device is characterized in that the lateral edge of the compass is fixed on the protection tube through a set screw, and connection keys are arranged between the protection tube and the guide tube. The compass orientation device for the longhole ground stress testing cannot deviate in the process of testing a longhole, not only has high precision and accurate orientation and solves the difficulty of orientation of a vertical drill hole, but also overcomes the defects of the traditional manual method which is cumbersome and has errors since a drill stem is marked out and an orifice is oriented by the compass. The utility model is accurate and convenient and improves the test efficiency.
Description
Technical field
The utility model relates to a kind of deep hole terrestrial stress test compass direction finder.
Background technology
The magnitude (stress value) and the direction of on-the-spot geostress survey are the engineering design important indicators.The size of terrestrial stress is measured by 36-3 type borehole deformeter, adopts compass usually and measure direction in the test of upright opening terrestrial stress.Existing compass tiltmeter is by guide pipe, and the compass timer is formed, and compass is free attitude in pipe, rotates freely the angle of measuring skew direction and deflection according to hole scattering.But the test for deep hole is to rule on drilling rod, and aperture compass orientation is heavy and the manual method of error is arranged, and is inconvenient and inaccurate.
Summary of the invention
The purpose of this utility model provides a kind of improved deep hole terrestrial stress test compass direction finder, and its degree of accuracy height, direction are accurate, has solved the difficult problem of vertical drilling orientation.
The technical solution of the utility model is:
Deep hole terrestrial stress test compass direction finder comprises protection tube, compass, timer, guide pipe composition; Compass, timer place in the protection tube and are fixed by timer top fixed screw, and protection tube places in the guide pipe, it is characterized in that the side of compass is fixed on the protection tube by fixed screw, between protection tube and guide pipe connecting key is arranged.
The deep hole terrestrial stress test compass direction finder of the utility model (improving the back) can not be offset when carrying out the test of deep hole, not only degree of accuracy height, direction are accurate, solved the difficult problem of vertical drilling orientation, and overcame originally and on drilling rod, rule, aperture compass orientation, heavy and the manual method of error arranged.Promptly accurately convenient again, improved test efficiency.

Fig. 1 is deep hole terrestrial stress test compass direction finder (protection tube) structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is deep hole terrestrial stress test compass direction finder (guide pipe) structural representation of the present utility model.
Fig. 4 is the vertical view of Fig. 3.
Among the figure, 1-fixed screw, 2-protection tube, 3-timer, 4-protection tube external key, 5-top fixed screw, 6-guide pipe, 7-keyway, 8-deformation gauge feed beam, 9-compass.
Embodiment
As shown in the figure, deep hole terrestrial stress test compass direction finder comprises protection tube 2, compass 9, timer 3, guide pipe 6 compositions; Compass 9, timer 3 place in the protection tube 2, and fixing by timer top fixed screw 5, protection tube 2 places in the guide pipe 6, and the side of compass 9 is fixed on the protection tube by fixed screw 1, at protection tube 2 and 6 of guide pipes connecting key (7 place) is arranged.Compass can not rotate it after fixing by screw 1 and 5.The socket center of deformation gauge feed beam 8 that is installed in the guide pipe bottom is consistent with the compass east-west direction, connect guide pipe with drilling rod deformation gauge is sent into measurement aperture in the upright opening, according to the time of the predetermined compass timer of boring different length, timer reaches behind the preset time the compass auto lock, check the direction of compass locking, just may calculate the position angle of 4 steel loops of deformation gauge successively.So both simply suitable, improved test accuracy and counting yield again greatly.
