Abstract
The invention relates to the field of an analyzing and measuring control technology, and discloses a shearing apparatus. The shearing apparatus comprises a shearing box composed of an upper box body and a lower box body which are communicated with each other and can slide relatively, a stress testing table of which one end is fixed to the lower box body and the other end is provided with a supporting frame, a force applying module arranged on the supporting frame in order to generate a pull force or push force in the direction from the lower box body to the supporting frame, and a force meter connected with the upper box body and the force applying module. In the shearing apparatus, the volume of the shearing box formed by the upper and lower box bodies can be manufactured as required, the enough volume can be guaranteed, so as to accurately measure barren rocks and mineral waste residues in each mining area, and thus the blank that a testing apparatus in the prior art cannot measure large ore in the mining area is filled up; with the combination of the shearing box, the force applying module and the force meter, the accurate measurement for the shearing force of the barren rocks stones and mineral waste residues in the mining area can be realized.
Description
technical field [0001] The invention relates to the technical field of analysis and measurement control, in particular to a shearing instrument, which is used in the restoration process of abandoned mine land to measure the shear stress and stability analysis of mine rock and soil, and to provide standards and standards for mine restoration. The basis is to ensure the personal and property safety of residents in the project area. Background technique [0002] Soil is a bulk material composed of solid, liquid and gas phases. In general, under external loads, the stress in the soil will change. When the shear stress in the soil exceeds the shear strength of the soil itself, the soil will slide along one of the cracked surfaces, causing the soil to lose its overall stability. Therefore, the failure of soil is usually shear failure. The shear strength of the soil refers to the limit or allowable shear force that the rock and soil can withstand on the shear plane. It is the ul...
