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 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 of rock-soil anchorage quality and the increase of engineering cost 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.

The horizontal and vertical plates of the frame are closely attached to the slope/wall surface, so when other conditions except the depth of the anchor hole meet the design requirements, the depth of the anchor hole can be accurately measured, combined with re-drilling or filling of the anchor hole, so that The depth of the anchor hole conforms to the design depth to ensure that the anchor hole goes deep into the stable rock and soil mass, and the rock and soil mass is anchored and supported by the anchor rod, so as to avoid the rock and soil anchorage being outside the fracture surface of the rock and soil mass due to too shallow anchor holes. The anchoring effect cannot be achieved and the anchor hole is too deep to cause unnecessary waste.

3. Since the horizontal plate in the present invention is provided with a compass, the horizontal state of the horizontal plate can be calibrated and the azimuth angle of the anchor hole can be measured; at the same time, the 180° angle plate and its center can be arranged on the side of the upper section of the sliding sleeve. The suspended weight can measure the inclination angle of the anchor hole, and the slope angle or rock-soil wall angle can be measured by means of the 90° angle plate on the horizontal plate of the chassis, so that the anchor hole position can meet the design requirements in space. Arrangement to ensure the reasonable distribution of rock and soil anchoring force and anchoring effect, so as to achieve the purpose of strengthening rock and soil.

4. According to the rock-soil anchoring effect, by means of the anchor hole depth, inclination angle, azimuth angle and slope/wall angle measured by the present invention, the rationality of the rock-soil anchoring scheme can be checked, and the design and optimization of the rock-soil anchorage can be evaluated and optimized. Construction is conducive to improving the anchoring effect of rock and soil, and improving the safety and reliability of the project.

5. The invention has the advantages of simple structure, simple processing and convenient use, and can be widely used in rock and soil anchoring construction.
