Abstract

The invention discloses a drilling azimuth angle and dip angle positioning device and a positioning method thereof. The drilling azimuth angle and dip angle positioning device comprises a base unit, an adjusting unit, a dip angle measuring unit and an azimuth angle measuring unit, wherein the adjusting unit is fixed onto the base unit and used for adjusting the reference positions of the dip angle measuring unit and the azimuth angle measuring unit; the dip angle measuring unit and the azimuth angle measuring unit are fixed onto the adjusting unit, the dip angle measuring unit is used for measuring drilling dip angles, and the azimuth angle measuring unit is used for measuring drilling azimuth angles. The drilling azimuth angle and dip angle positioning device has the advantages that the drilling azimuth angles and dip angles can be positioned conveniently, fast and accurately before drilling; the drilling azimuth angles and dip angles can be positioned by using the properties of parallel lines and isosceles triangles, using laser ranging and orientation functions matched with an auxiliary mechanism and using the dip angles and azimuth angles of a drill stem to position the azimuth angles and dip angles of an orifice pipe, operation by one person is achieved, and the azimuth angles and dip angles of the drill stem can be measured fast and accurately in a dynamic and integrated manner.

Description

technical field [0001] The invention belongs to the field of various drilling constructions of tunnels, mines and other underground engineering, and in particular relates to an azimuth and inclination positioning device and a positioning method for various drilling holes in underground engineering. Background technique [0002] At present, the construction of underground projects such as tunnels, subways, hydropower stations, and mines is booming in China. During the construction of underground projects, abnormal and adverse geological environments often encounter major geological disasters such as water and mud inrush, deformation of surrounding rocks, and even collapse. The management of geological disasters is inseparable from drilling, so the quality of drilling construction is directly related to the success or failure of the project. One of the keys that affect the quality of drilling construction is the accuracy of the positioning of the drilling track, that is, the p...
