Abstract
The utility model relates to a measuring apparatus for coal mine underwell tunneling construction and especially relates to a measuring instrument for a geological drill hole orientation angle. The measuring instrument is structured in a way of comprising a vertical edge, a supporting edge and a swinging edge, wherein one end of the vertical edge is fixedly connected with the supporting edge; and the other end of the vertical edge is movably connected with the swinging edge. Compared with the prior art, the measuring instrument for the geological drill hole orientation angle is simply structured with easy carrying and convenient usage; by the use of the measuring instrument, standardized precision of a geological drill hole plane orientation angle is guaranteed, so accurate positioning for geological structure body detection can be ensured; and the measuring instrument can be simply operated, so orientation check and correction can be conducted at any time.
Description
Technical field
The utility model relates to tunneling construction measuring apparatus under a kind of coal mine, is specially a kind of geotechnical boring azimuth angle measurement instrument.
Background technology
Down-hole, to geological structure or cheat in the drilling process of exceptions area, for the accuracy and the actual probing that guarantee results of drilling need, need to accurately be determined the flat orientation angle in geology structural exploration hole.Traditional way is that the azimuth circle that utilizes surveyor's transit is determined (or the method for utilizing tape measure to calculate is demarcated roughly), said method is in calibration process, orientation and inclination angle required precision to boring are higher, operating procedure is loaded down with trivial details, length consuming time, manpower and materials have high input, cannot realize geological drilling personnel measures at any time to the orientation angles of geotechnical boring, thereby cause geological drilling inefficiency, the orientation of boring and the error at inclination angle, directly have influence on accuracy and the precision of geological drilling result.
Summary of the invention
The utility model, in order to solve the problems such as the measurement azimuth complex steps existing in existing down hole drill, provides a kind of geotechnical boring azimuth angle measurement instrument.
The utility model is realized by following technical scheme, a kind of geotechnical boring azimuth angle measurement instrument, and structure comprises perpendicular edge, support edge, swing limit, described perpendicular edge one end is fixedly connected with support edge, and the other end and swing limit are flexibly connected.
During use, by vertical with rib perpendicular edge, arrange, then the direction that swings limit and drilling rod is adjusted into unanimously, the angle that at this moment swings limit and perpendicular edge is exactly azimuth or the inclination angle of drilling rod.
Compared with prior art, the utility model is simple in structure, carry with easy to use, by enforcement, use geotechnical boring azimuth angle measurement instrument, can guarantee the stated accuracy of geotechnical boring grid azimuth, guarantee the accurate location that geology tectosome is surveyed, easy and simple to handle, can to orientation, test at any time and correct.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1-perpendicular edge, 2-swings limit, 3-support edge, 4-angle calibration hole.
The specific embodiment
As schematically shown in Figure 1, a kind of geotechnical boring azimuth angle measurement instrument, structure comprises perpendicular edge 1, support edge 3, swing limit 2, described perpendicular edge 1 one end is fixedly connected with support edge 3, and the other end and swing limit 2 are flexibly connected.
Be provided with angle calibration hole 4 swinging on limit 2, described 4 positions, angle calibration hole can corresponding corresponding angle, and the registration of demarcating hole 4 and swing limit 2 by viewing angle can judge the general numerical value of angle.
