Rock sample cutting device capable of producing different joint angle and different joint connectivity rates

Abstract

A rock sample cutting device capable of producing different joint angle and different joint connectivity rates comprises a stainless steel support, a cutting machine is arranged on one side of the upper end of the stainless steel support through a jack and is driven by a motor, a cutting blade is arranged on the main rotation shaft of the cutting machine, an operation flat disc is arranged on the stainless steel support plane below the cutting blade, two-way rotation flat tongs are arranged above the operation flat disc, and a longitudinal dovetail plate and a transverse dovetail plate are arranged below the operation flat disc and are used for controlling the longitudinal and transverse moving of the operation flat disc. An indexing disc base is arranged at the bottoms of the two-way rotation flat tongs, and a rock sample to be cut is driven by the two-way rotation flat tongs to be capable of rotating between 0-360 horizontally and 0-90 vertically. The device is capable of obtaining batch continuous single-joint rock test pieces of different angles and different joint connectivity rates, simple in instrument manufacture, high in cutting accuracy, safe and environmentally friendly, convenient and reliable to operate and capable of achieving multi-dimensional control.

technical field [0001] The invention belongs to the field of civil engineering, and relates to equipment for making rock specimens with different joint inclination angles and different joint connectivity ratio angles, in particular to a rock sample cutting machine capable of manufacturing different joint angles and different joint connectivity ratios. Background technique [0002] In nature, most rock bodies have various geological interfaces, including material differentiation surfaces and discontinuities, such as folds, faults, bedding, joints, etc., which will make the rock mass show very obvious anisotropy characteristics , in engineering, the anisotropic properties of rock mass often determine the safety of engineering construction and engineering structures. The urgent need for discipline development.

Problems solved by technology

However, due to factors such as the complexity of the field test and the high cost, the current experimental research on rock mass anisotropy is mostly based on laboratory tests.

The research object of indoor test is mostly carried out with rock mass specimens with penetrating joints of a certain size, and there are still few studies on rock mass with no penetrating joints. This is mainly due to the complexity of the rock mass structure itself and the limitation of indoor conditions. It is very difficult to produce non-penetrating jointed rock samples with different joint dip angles, and it is very difficult to accurately batch produce single-joint bedding rock mass specimens with different connectivity rates; It is practicable to cut out rock mass specimens with different joint inclination angles and different connectivity ratios, but because the existing cutting equipment hardly considers the problem of cutting single-joint rock samples with different angles and different depths, the cutting direction is Fixed, for rock samples of the same size, the cutting depth is also fixed. At the same time, rock samples in the general sense cannot be fixed well due to their small size. Due to the above difficulties, there is still no good cutting depth. The method can simply and quickly obtain batches of single-joint rock mass specimens with different angles and different connectivity rates.
