Abstract

The invention discloses an anti-settlement instrument for a direct shear test structure surface sample, which comprises a base on which a bracket is fixedly installed, the upper end of the bracket is provided with a perforation and a balance bar is fixedly installed through a nut, and the side wall of the balance bar is provided with Thread, one end of which is fixed with a balance weight, and the other end is fixed with a wrench holder through a connecting piece. The wrench holder includes two sets of four horizontal slotted clamps and vertical clamps, each with two horizontal slotted clamps and two longitudinal clamps It is in the shape of a "well" and is fixed and installed by vertical foot screws. There is a level bubble in the horizontal grooved fixture, and the longitudinal fixture is fixed in the groove of the horizontal grooved fixture through a horizontal nut. The invention not only has simple structure, easy disassembly and convenient operation, but also has low cost and good effect.

Description

Technical field: [0001] The invention relates to the technical field of making structural surface models used in "XJ-type portable shear instrument for measuring structural surface shear strength" in rock mechanics, in particular to an anti-subsidence instrument for direct shear test structural surface samples. Background technique: [0002] In geotechnical engineering, in order to evaluate the stability of the rock mass structural plane, it is necessary to obtain the shear strength index of the structural plane through the direct shear test. In geology, water conservancy, railway, highway, municipal and other related engineering fields, the shear strength index of the structural surface is one of the very important mechanical parameters in engineering design and rock mass stability evaluation. If the shear strength index is not accurate, it will directly lead to Large deviations are caused in engineering applications. The shear strength index of the rock mass structural su...
