Crack measuring device for hydraulic ring geological survey based on 3D scanning

Abstract

The invention discloses a crack measuring device for hydraulic ring geological survey based on 3D scanning, and relates to the technical field of geological survey, the crack measuring device comprises a supporting plate, the cross section of the supporting plate is in an inverted L shape, a groove is formed in the outer wall of the top of the supporting plate, and rotating columns are rotationally connected to the inner walls of the two sides of the groove; a top plate is fixedly connected to the circumferential outer wall of the rotating column, and a positioning assembly is arranged on the outer wall of the bottom of the top plate. When a worker moves the device to a to-be-detected area, the limiting effect of a coupler on a rotating rod can be relieved, at the moment, a top plate can do circular motion through a rotating column due to the gravity factor, and in the rotating process of the top plate, a positioning assembly arranged at the bottom of the top plate bears high downward pressure of the top plate; at the moment, the positioning assembly can be inserted into the soil through downward pressure generated by rotation of the top plate, so that the stability of follow-up crack detection work can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of geological survey, in particular to a 3D scanning-based fracture measuring device for geological survey of hydraulic ring. Background technique [0002] The work of hydraulic environment geology is divided into comprehensive environmental geological survey and specialized environmental geological survey according to different purposes and requirements. For a specific purpose or use, environmental geological survey and research work specifically for a certain environmental geological problem or geological disaster, engineering construction, excavation, blasting, mining and other human activities often cause damage to rock and soil mass and damage. Instability, which leads to the occurrence of surface cracks. The cracks appear in the stress concentration area of ​​the rock and soil mass or where the strength is relatively low. Its development and changes will naturally affect normal engineering construction...

AI Technical Summary

Problems solved by technology

[0004] But the above-mentioned invention has the following disadvantages: although the crack width can be measured, the whole device is too bulky, and it needs staff to fix it at both ends of the crack. If the geological crack is too large, the surveyor will not be able to The device moved to the other side of the crack, which brought great inconvenience to the geological personnel to detect the crack. At the same time, when the staff fixed the device on both sides of the crack, there was a high potential safety hazard, which could not satisfy people. usage requirements
