Problems solved by technology
The current sampling method has the following disadvantages: 1, the instability of the device, the instability of the embedded rock, causing the vibration of the rock in the cutting process; 2, although the surface of the rock sample is relatively smooth with a triaxial drilling machine, the The cost is high and the size is single, and only cylindrical rock samples with a certain size can be produced; 3. The cutting system is backward, and the general cutting system is not very accurate in grasping the size, which is easy to cause vibration and manual errors that lead to sampling size. imprecise

A main body structure of the cutting and sample preparation integrated device comprises upperbolts, a bolt pushing rod, a sample cap, sliding slots, fixed clamping arms, rock samples, baffle plates, lower bolts, a rotating handle, a dust-proof plate, a saw blade, a movable base, a track, driving pulleys, a platform, a cutting arm, a spiral pushing handle, a sample preparation base and lateral fixed bolts. According to the cutting and sample preparation integrated device disclosed by the invention, the rock samples of different sizes can be freely and flexibly cut, the sizes are accurate, a cut surface is smooth, and the high-quality rock samples can be provided for various mechanicalproperty tests of rocks.
Description
Technical field: [0001] The invention belongs to the technical field of geotechnical engineering and geological engineering, and discloses an integrated device for cutting and sample preparation of soft rock, in particular to a test device and a test method for on-site investigation and sampling of geotechnical engineering. Background technique: [0002] In civil engineering tests, especially for rock mechanics engineering and mining engineering, it is a common method to study the mechanical properties of rock samples through engineering survey technology and sampling technology, and the ring knife method is generally used for sampling soil samples , the operation is simple, but it is generally aimed at soil samples; the rock mechanics experiment is the key method to study the physical and mechanical properties of the surface and deep underground rocks. sample, the size is mostly Φ25mm*50mm or [0003] Φ50mm*100mm. The current sampling method has the following disadvantage...
