An in-situ measurement device for creep effect of dissolution dikes

By controlling the rotation of the shaft through the drive component and the self-locking structure, the pressure plate is driven to apply pressure evenly, which solves the problem of the limitation of the rock and soil measurement results in the existing technology and realizes a more accurate measurement of the creep effect of dissolution dikes.

AI Technical Summary

Technical Problem

In existing technologies, when using pressurized gas or medium oil for soil and rock measurements, it is difficult to ensure that the stress is uniform in different parts of the soil and rock, resulting in limited measurement results that cannot be universally applied to soil and rock with different hardness.

Method used

An in-situ measurement device for the creep effect of soluble rock veins is adopted. The rotating shaft is controlled by the drive component and the self-locking structure, which drives the side pressure plates to expand or converge radially, ensuring that the force of each side pressure plate on the rock and soil is evenly distributed. Uniform pressure is achieved by using mechanical cooperation.

Benefits of technology

This method achieves uniform stress distribution across all parts of the soil and rock, obtains more general and extensive measurement data, and improves the accuracy and applicability of the measurements.

Abstract

This invention discloses an in-situ measuring device for the creep effect of soluble rock veins in the field of geotechnical material experimental technology. It includes a shell and a rotating shaft rotatably disposed inside the shell. Multiple pressure plates are equidistantly distributed along the circumference of the bottom outer perimeter of the shell, forming a pressure ring. During the rotation of the shaft, the pressure plates expand outward or converge inward along the radial direction of the pressure ring. A self-locking structure is provided at the top of the shell, and a driving component is also provided at the top of the shell, connected to the self-locking structure. This invention, through the cooperation of the driving component and the self-locking structure, controls the rotation of the shaft inside the shell to form a self-locking mechanism. During the rotation of the shaft, the multiple pressure plates expand outward or converge inward along the radial direction of the pressure ring, ensuring that the forces exerted on the soil and rock by the multiple pressure plates are equal, avoiding situations where the soil and rock experience different forces, thereby obtaining more general and extensive measurement data.
