Problems solved by technology
The geometric parameters of blastholes required for TSP advanced geological prediction include hole depth, hole height, hole spacing, inclination and azimuth, while the TSP 203plus system is only equipped with an electronic goniometer and a hand-held laser rangefinder, which can measure the blasthole more accurately. Hole inclination angle and the distance from each blast hole to the receiving hole, while the tunnel measurement environment and methods are complex, it is impossible to accurately measure parameters such as hole depth, hole height and azimuth angle, which affects the accuracy of measurement results

The invention relates to an omnibearing measurement device and method for a tunnel TSP (Total Suspended Particulate) geometric parameter. The device comprises a depth measuring scale, wherein the depth measuring scale and a pitch measuring scale are vertically arranged and can be connected in a sliding mode by virtue of an annular fixer; the end part of the depth measuring scale is provided with a water level base; the water level base is spirally connected with and mediates a circular water level by virtue of a plurality of pins; the circular water level is vertically connected with a heightmeasuring scale by virtue of a vertical fixer; the water level base is connected with an extending plate; the water level base and the extending plate are parallel to the depth measuring scale; and the circular water level is provided with a dip angle survey meter. According to the omnibearing measurement device, the TSP shotpoint geometric parameter can be simultaneously measured. The omnibearing measurement device adapts to the complex measurement environment of the tunnel, the measurement method is simple and accurate, and the measurement time is saved.
Description
technical field [0001] The invention relates to a tunnel parameter measuring device and method. Background technique [0002] As an indispensable part of the dynamic design and construction of tunnel information, advanced geological prediction timely predicts the adverse geological conditions in front of the tunnel face in order to take effective measures in advance to avoid geological disasters and ensure the safety of tunnel construction. It has been recognized by the engineering community. wide recognition. Tunnel Seismic Prospecting (TSP) is one of the main methods of non-destructive long-term advance geological prediction during the construction period, and has become one of the most widely used prediction methods in the information construction of long tunnels. The measurement of blasthole geometric parameters is an important part of the preparation work before TSP data collection, and it is crucial to the accuracy of subsequent processing. Only on the premise of accu...
