The tester is simple in structure, simple to machine, convenient to use, and wide in application.
Description
Technical field
The present invention relates to blasting technique field, relate in particular to hole depth and inclination angle and the azimuth observations instrument of shot hole.
Background technology
Explosion is widely used in the many-sides such as mining, water conservancy, highway, railway, urban construction, and its demolition effect directly affects quality, progress and the cost etc. of engineering, plays key effect in engineering.In blasting works, before explosion, need on bursting work face, bore many shot holes, then in these holes, pack explosive into, can implement explosion.But in bursting work at present, often because the hole depth of shot hole is too dark or too shallow, inclination angle is too large or too little, azimuth forbidden to cause the step that forms after explosion not in one plane, retain wall not on a slope, and cause rock bank, bulk etc. to affect demolition effect, also may cause blasting flyrock, explosion earthquake etc., safety is constituted a threat to.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of hole depth and inclination angle and azimuth observations instrument of shot hole simple in structure, easy to use.
For addressing the above problem, the hole depth of shot hole of the present invention and inclination angle and azimuth observations instrument, is characterized in that: it comprises level frame, sliding sleeve and is sleeved on the hole depth measuring stick with scale in described sliding sleeve; On described level frame, be respectively equipped with angle scale and compass, and be connected with described sliding sleeve by hinge; The lower end of described sliding sleeve has dial window upward.
Described level frame is mutually vertically connected on and is formed together T shape frame by two level boards.
Described sliding sleeve is rectangle pipe.
Described hole depth measuring stick is straight-bar.
The present invention compared with prior art has the following advantages:
1, because the hole depth measuring stick in the present invention is straight-bar, and there is enough rigidity, therefore, be different from and be usually used in the dark rope of gaging hole, avoided rope easily bending in hole, thereby caused shot hole hole depth to measure inaccurate problem.
2, because the sliding sleeve in the present invention is with to be sleeved on hole depth measuring stick wherein all vertical with the upper seamed edge of the level board being connected with sliding sleeve by hinge in level frame, and two level boards of level frame all have certain length, when shot hole is measured, hole depth measuring stick is placed in to downward shot hole, by the effect of gravity, make hole depth measuring stick total length be close to shot hole hole wall circumference lowest part, its bottom contacts with at the bottom of shot hole hole, two level boards of level frame are level, thereby energy Measurement accuracy shot hole hole depth, under the identical condition in shot hole inclination angle, the bottom, shot hole hole of same hole depth at grade, thereby make the step that forms after explosion smooth, having eliminated too dark or too shallow the causing of shot hole backbreaks or owes to dig not phenomenon in one plane of caused step.
3,, because the level frame in the present invention is provided with angle scale, therefore, can measure the inclination angle of shot hole; Meanwhile, the compass being provided with by level frame can be measured the azimuth of shot hole; In the time that the inclination angle of same explosive holes is consistent with azimuth, the residual wall after explosion will drop on a slope, can eliminate the overbreak-underbreak that explosion causes, and be conducive to the stable of side slope.
4, according to demolition effect, the shot hole hole depth, inclination angle and the azimuth that obtain by means of the present invention, can check the reasonability of blasting scheme, and evaluation and optimization explosion design, construction, be conducive to improve demolition effect, security implementation explosion.
5, the present invention simple in structure, process simple and easy, easy to usely, can be widely used in drill eye blasting.

The specific embodiment
As shown in Fig. 1 ~ 5, the hole depth of shot hole and inclination angle and azimuth observations instrument, it comprises level frame 3, sliding sleeve 5 and is sleeved on the hole depth measuring stick 4 with scale 7 in sliding sleeve 5.
Hole depth measuring stick 4 is straight-bar, and can slide and rotate with the upper seamed edge of the level board being connected with sliding sleeve 5 by hinge 10 in level frame 3 in company with sliding sleeve 5 with respect to sliding sleeve 5, and can read the scale 7 on hole depth measuring stick 4 by dial window 6.
When use, level frame 3 is placed in the limit, aperture of shot hole 2 incline directions on bursting work face 1, makes level frame 3 in level; Hole depth measuring stick 4 is sleeved in sliding sleeve 5, and its bottom is placed in shot hole 2, and it is slided with respect to sliding sleeve 5, until contact at the bottom of the hole of its bottom and shot hole 2; By the effect of gravity, make hole depth measuring stick 4 total lengths be close to shot hole 2 hole wall circumference lowest parts; Sliding sleeve 5 is with to be sleeved on hole depth measuring stick 4 wherein all vertical with the upper seamed edge of the level board being connected with sliding sleeve 5 by hinge 10 in level frame 3.Now, in the dial window 6 of sliding sleeve 5 rectangle pipe lower ends, the scale 7 of hole depth measuring stick 4 is the degree of depth of shot hole 2; Sliding sleeve 5 that is rectangle pipe and horizontal direction angle are the inclination angle of shot hole 2, and this angle can be pointed out by angle scale 8; Utilize compass 9 on level frame 3 to can read the azimuth of shot hole 2.
