Protolith structural plane sample manufacturing device and manufacturing method

Abstract

The invention provides a protolith structural plane sample manufacturing device and manufacturing method. A bearing table is used for bearing a structural plane lower disc, a first level gauge is usedfor being installed on the side wall of the structural plane lower disc, and a plurality of first height adjusting pieces are used for adjusting the first level gauge to be in a horizontal state; a lower disc die and an upper disc die are arranged in a square tube shape and extend in a vertical direction, the lower disc die is used for being installed on the periphery of the structural surface lower disc, and a lower fixing piece is used for fixing the structural surface lower disc. A supporting assembly comprises a supporting rod and a supporting cap, the supporting rod extends in the vertical direction, the supporting rod and the supporting cap are fixed to the outer side wall of the lower disc mold and the outer side wall of the upper disc mold respectively, the supporting rod matchesthe supporting cap to install the upper disc mold above the lower disc mold, the upper disc mold is opposite to the lower disc mold; and an upper fixing piece is used for fixing a structural surface upper disc. The protolith structural plane sample manufacturing device has the following beneficial effect: a problem of how to determine the horizontal state of the structural plane on the premise ofensuring that the structural plane upper disc and the structural plane lower disc of the sample are matched is solved.

Description

technical field [0001] The invention relates to the technical field of shear test devices for rock structural surfaces, in particular to a device and method for producing samples of structural surfaces of raw rock. Background technique [0002] In the direct shear test of the original rock structural surface indoors, it is usually required that the size of the sample meet certain standards. However, due to the limited sampling conditions of the original rock in the field, it is often impossible to obtain a sample size that fully meets the requirements of the laboratory test, so the rock needs to be reprocessed. The general method is to pour concrete around and at the bottom of the rock block to expose the upper structural surface to form a standard size sample. [0003] Although the prior art proposes a mold and a manufacturing method for structural surface samples of native rocks, the practicability is poor. The proposed method of filling protective materials (chips) near...
