Embodiment Construction

[0031] Below in conjunction with accompanying drawing, the course of work of the present invention is further described:

[0032] 1. Turn on the power and turn on E. High performance computing system.

[0033] 2. Start the E2. High-performance computer to check whether the status of each part of the pressure chamber is normal.

[0034] 3. After checking that the state of the pressure chamber is normal, raise the A. synchronous lifting system, place the rock block on the B1.1. clamping seat, and fix the bottom end of the rock block.

[0035] 4. After the rock block is fixed, E2. High-performance computer controls A. The synchronous lifting system descends along D3. The frame column until A4. The upper chamber of the pressure chamber is connected with the lower chamber of B2. The pressure chamber, and C1. The clamps are engaged Snap into A4.4. Bottom cover groove and B2.1. Barrel wall groove.

[0036] V. A1. The loading device moves down to the top of the rock block, ready to ...

Abstract

The invention relates to a novel pressure chamber for automatic output of fallen samples of a rock mass in a high-pressure environment, which belongs to the technical field of manufacturing of experimental instruments of rock and soil mechanics. The novel pressure chamber comprises a synchronous lifting system, an output system, a folding device, an external frame and a high-performance computer system. In the novel pressure chamber, the structure of the existing pressure chamber is improved; the novel pressure chamber has the following main values: 1, in order to reduce discreteness of parameters in a rock sample test process, a same rock sample is adopted for a mechanical test under the high-pressure condition, the fallen samples of the rock mass in the test process are automatically output, and the physical properties, the chemical properties and the like of the rock mass are tracked and measured synchronously; 2, the scattered fallen samples of the rock mass in the pressure chamber can be timely cleaned, so that a test environment is optimized, and the precision is ensured.

Description

Technical field: [0001] The invention relates to a novel pressure chamber for automatically outputting rock block samples in a high-pressure environment, and belongs to the technical field of rock and soil mechanics experimental instrument manufacturing. It is suitable for pressure testing of rock samples in a high-pressure environment, and it is necessary to automatically output the samples of rock blocks falling off in the pressure chamber in time. Background technique: [0002] Triaxial compression test is a common method to measure the strength of rock samples, which can measure the axial and radial deformation of rock samples. Study the stress-strain relationship of the rock sample and obtain the constitutive relation of the rock sample. The three-axis compression instrument is composed of a pressure chamber, an axial loading system, a confining pressure loading system, and a pore water pressure measurement system. The conventional triaxial compression instrument is o...
