Drilling rock core level dip meter

Abstract

The invention provides a drilling rock core level dip meter. The drilling core level dip meter comprises a measuring unit, an adjusting unit and a rock core fixing assembly which are connected in sequence. The measuring unit comprises a reading dial, an indication rod and a fit plate. The reading dial is in a fan shape. An arc-shaped side edge of the reading dial is provided with angle scales. End parts of the indication rod and the fit plate are fixedly connected and are perpendicular to each other. The connection part between the indication rod and the fit plate is hinged with the circle center of the reading dial. The adjusting unit comprises an upper shaft frame, a lower shaft frame, an adjusting handle and a rack and pinion mechanism. The dip meter is designed in strict accordance with principles related to rock core dip measurement, the fit plate and the indication rod perpendicular to each other are designed, and the rock core is placed in a pallet in the rock core measuring process, so that the dip reading can be rapidly read only if the rock core level is fit with the fit plate; and in this way, a tedious process in conventional dip measurement that the instruments needs to be repeatedly adjusted to determine the inclination is omitted, and the dip measuring efficiency is greatly improved.

Description

technical field [0001] The invention relates to a drilling core inclination measuring instrument, which belongs to the technical field of geotechnical engineering investigation. Background technique [0002] The inclination angle of the layer in the drilled core is one of the important stratigraphic information that needs to be revealed by drilling in geotechnical engineering investigation. Accurately obtaining the inclination angle of the middle layer of the core is an important basis for accurately establishing a slope geological model, and has important engineering practical significance in slope stability evaluation. Obtaining the distribution law of stratum dip angle in underground space through core dip angle information is helpful to analyze the development characteristics of underground strata structure. In areas where the dip angle of rock formations changes significantly with depth, finding out the variation law of the dip angle with depth can be used to analyze t...

AI Technical Summary

Problems solved by technology

Since it is difficult to ensure that the bottom edge of the circular scale plate is perpendicular to the core, and it is also difficult to determine the inclination of the layer, the accuracy of the measurement results is difficult to guarantee

No special instrument or equipment has been found for measuring the dip angle of the core bedding
