A Comprehensive Measuring Instrument for the Occurrence of Joint Group Structural Surface

Abstract

The invention relates to a comprehensive measuring instrument for joint set structural surface occurrences. The instrument comprises a main ruler, an auxiliary ruler and a telescopic tape slope measuring mechanism, wherein each of the main ruler and the auxiliary ruler comprises a handheld column, a rotating column, a water tank compass, a separation plate, a side plate and an angle ruler; the handheld columns, the separation plates and the side plates are sequentially and integrally connected, located on the same back surface and have sheet-wedge-tip-shaped bottoms, the rotating columns are connected onto the handheld columns and the side plates through rotating shafts at lower parts of the rotating columns, the water tank compasses are arranged at tops of the rotating columns, and the angle rulers penetrate through the separation plates to be movably connected with the rotating columns. During usage, the sheet-wedge-tip-shaped bottoms of the handheld columns, the separation plates and the side plates of the main ruler and the auxiliary ruler are inserted in adjacent joint fissures in to-be-measured joint sets, meanwhile, the rotating columns of the main ruler and the auxiliary ruler are rotated to be in a vertical state, and parameters of the structural surface occurrences of the to-be-measured joint sets are obtained by the aid of the angle rulers and the tape slope measuring mechanism. Compared with the prior art, the instrument has the advantages that the instrument is diversified in function, small in accumulated error, high in working efficiency, convenient to carry, simple in calculation and the like.

Description

technical field [0001] The invention relates to the technical fields of geological engineering and geotechnical engineering survey, in particular to a comprehensive measuring instrument for the occurrence of structural planes of joint formations, which is used to measure the space direction, inclination, inclination, distance between joints of structural planes of rock and soil bodies, and the development of structural planes. The terrain slope and other parameters. Background technique [0002] Joint groups composed of structural planes with similar spatial occurrences are often developed in rock and soil. Obtaining the spatial direction, inclination, dip angle, joint spacing and other parameters of the structural planes in the joint group is an important basis for studying its mechanical properties and engineering stability. At present, these parameters are generally obtained by measuring in rock and soil with tools such as a geological compass and a tape measure. Such ope...

AI Technical Summary

Problems solved by technology

At present, these parameters are generally obtained by measuring in rock and soil with tools such as a geological compass and a tape measure. Such operations are cumbersome and inefficient, and the step-by-step cooperation of various tools often leads to large accumulated errors. In addition, Field surveys should be carried lightly, and carrying multiple tools will increase survey costs and reduce work efficiency

[0003] There is no report on the equipment that can comprehensively obtain the spatial direction, inclination, inclination angle, joint spacing and other parameters of the structural plane of the joint group.
