Tester for depth, dip angle, azimuth, slope/wall angle of anchor hole

Abstract

The invention relates to a tester for the depth, dip angle, azimuth, slope/wall angle of an anchor hole. The tester comprises a bottom frame, a horizontal plate, a slide bushing and a hole depth measuring rod having scales and sleeved in the slide bushing; the horizontal plate is provided with a compass and is connected with the slide bushing by a hinge II; a 180-degree angle disc is arranged at the side surface of the upper section of the slide bushing; an upward scale window is arranged at the lower end of the slide bushing; a heavy hammer is suspended at the center of the 180-degree angel disc; a 90-degree disc is arranged on the bottom frame and is connected with the horizontal plate by a hinge I. The tester can be used for testing the depth, dip angle, azimuth, slope/wall angle of the anchor hole, thus evaluating and optimizing anchoring design and construction and improving the rock soil anchoring effect. The tester is simple in structure, simple and easy for operation, convenient to use and wide in application.

Description

technical field [0001] The invention relates to the technical field of rock and soil anchoring, in particular to an instrument for measuring anchor hole depth, inclination angle, azimuth angle and slope / wall angle. Background technique [0002] Geotechnical anchoring is widely used in mining engineering, water conservancy engineering, highway engineering, railway engineering, marine engineering, urban construction engineering, and national defense engineering. Its anchoring effect directly affects the quality, progress, and cost of these projects, and plays an important role in engineering Key role. In geotechnical anchoring engineering, before anchoring, it is necessary to drill many anchor holes on the rock and soil mass, then install anchor rods in the anchor holes, and fill the grout to realize geotechnical anchoring. However, in rock-soil anchoring construction operations, it is often caused that the anchor hole is drilled too deep or too shallow, the inclination angle...

Problems solved by technology

However, in rock-soil anchoring construction operations, it is often caused that the anchor hole is drilled too deep or too shallow, the inclination angle is too large or too small, and the azimuth angle and slope (wall) angle are not accurate, which affects the implementation of the rock-soil anchoring scheme and design, resulting in The decline in the quality of rock-soil anchorage and the increase of engineering costs will weaken the effect of rock-soil anchorage and reduce the durability of the project, thereby hindering the promotion and development of rock-soil anchorage technology, and even seriously affecting the overall quality of the project, posing a threat to project safety
