Device used for producing schist similar materials

Abstract

The invention relates to a device used for producing schist similar materials. The device comprises a mould without an upper cover, wherein a blanking device is arranged on the mould, and comprises an even number of vertical sliding rails, transverse sliding rails and a blanking trough, wherein the vertical sliding rails are vertically and symmetrically arranged above a pair of opposite side walls of the mould, each vertical sliding rail is provided with a vertical sliding block, two ends of the transverse sliding rail are fixedly connected with the two vertical sliding blocks respectively, the transverse sliding rail is provided with a transverse sliding block, the transverse sliding block is fixedly connected above the blanking trough by a connecting rod, the length of the blanking trough is not greater than the length of the inner edge of the mould perpendicular to the transverse sliding rail, and two side edges of a discharging hole of the blanking trough are respectively provided with a scraping plate which is turned up outwards and upwards. The device provided by the invention is simple in structure and convenient to assemble, can precisely control the thickness and evenness of each layer, and can control the arrangement direction of flaky materials to simulate the structural characteristics of schist, so as to produce experimental materials with structure and constitution similar to those of the schist, and provide the materials with high similarity for experimental research.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a device for making schist-like materials. Background technique [0002] Metamorphic rock is one of the common rocks in engineering. Schistosed structure is a structural type of metamorphic rock. Schistosed rocks are characterized by the directional arrangement of flaky minerals and the interval distribution of flaky minerals and granular minerals. The layer thickness It is less than the layer thickness standard of engineering geological thin layered rock mass. These characteristics are important factors affecting the mechanical properties of schist, and the difference in mineral composition and content will also have an important impact on the mechanical properties of schist. [0003] Due to the origin of schist, the mineral composition of samples in the same borehole has strong heterogeneity, which interferes with the study of the influence of schist structure...

AI Technical Summary

Problems solved by technology

[0008] The minimum cutting thickness of a thin-layer cutting device for multi-interlayer model materials is much larger than the layer thickness of schist macroscopically, and it cannot simulate the state of interval distribution between sheet minerals and granular minerals

[0009] Use wooden molds to simulate joint surfaces with gypsum dry powder and soft materials. This simulation method leads to a large difference in the bonding method between layers and the connection method of schist crystallization, and it is difficult to make extremely thin interlayered similar materials.
