Geological measuring line with readable angle of pitch

Abstract

The invention provides a geological measuring line with a readable angle of pitch. The geological measuring line comprises a capstan, a capstan cover and a line body wound on the capstan, wherein the capstan cover is sleeved on the capstan, both the capstan cover and the capstan are sleeved on a center shaft and can rotate around the shaft, a through hole is disposed on a side wall of the capstan, the inner end of the line body penetrates through the through hole to be connected onto the center shaft and can rotate around the shaft, a graduated disc is arranged on the center shaft, the center of the graduated disc is sleeved on the center shaft, the graduated disc can rotate around the shaft, graduations are uniformly distributed on the graduated disc, a leveling device is arranged on the graduated disc, stop positions are disposed at two ends of the center shaft, and the capstan, the graduated disc and the capstan cover are mounted between the two stop positions. The geological measuring line overcomes shortcomings in the prior art, and is simple in structure and convenient and accurate in measurement.

Description

technical field [0001] The invention relates to a geological measuring rope capable of reading dip angles, in particular to a measuring tool used in field structural surface statistics, actual geological profile measurement and the like. Background technique [0002] The inclination angle of the measuring rope is an important original parameter of field geological survey. When the survey line method is used to calculate the parameters of the rock mass structural plane, the inclination angle of the measuring rope will directly affect the estimation of the average trace length of the structural plane, thus affecting the network simulation of the structural plane. The accuracy of the follow-up work, and when the intersection angle between the structural surface trace and the survey line is small, the calculated average trace length and the network simulation results deviate greatly from the actual situation, so it is necessary to adjust the inclination angle of the survey rope d...

AI Technical Summary

Problems solved by technology

When using traditional geological surveying ropes for field surveying, it is necessary to estimate the inclination angle of the surveying rope with the help of a geological compass, but there are obvious errors in estimating the inclination angle of the surveying rope with a compass, and the slope toe is often used instead of the surveying rope during measurement. The method of rope inclination angle, the error of the measurement result obtained in this way is very large, and the measurement steps are cumbersome

Therefore, it is a deficiency of the traditional geological survey rope that the inclination angle of the survey rope cannot be directly known during the measurement process. Based on the above reasons, it is necessary to develop an effective geological survey rope that can directly measure the dip angle of the survey rope. The problem
