Real-time tester for multi-environment simulated rock disaggregation process

Abstract

The invention relates to a real-time tester for a multi-environment simulated rock disaggregation process. The tester consists of six parts, namely a disaggregation container system, a solution system, a drying and watering cycle system, an automatic screening system, a data monitoring system and a supporting base system. According to the real-time tester, observation and description of rock disaggregation states of high analogue simulation rocks under environmental conditions such as dynamic water spraying, static soaking, drying and watering cycle, airing and temperature change can be realized, and the amount change conditions of disaggregation substances of various particle sizes can be continuously monitored in real time, so that the rock disaggregation characteristics are analyzed, the rock self-sustaining capacity is evaluated, and the tester is novel test equipment which can be widely applied to engineering geological surveying teams, colleges and universities, research and development institutions and the like.

Description

technical field [0001] The invention relates to a rock disintegration test equipment, in particular to a combination of various components, which can realize real-time observation of rock disintegration conditions under simulated various environmental conditions and quantitative monitoring of disintegrated products, so as to study rock disintegration A new type of test instrument for the characteristics and evaluation of rock self-sustaining ability. Background technique [0002] There are mainly two methods for the experimental research on rock disintegration at home and abroad: disintegration resistance test and ordinary disintegration test. [0003] The standard of disintegration resistance test method is mainly the method suggested by the International Society of Rock Mechanics (ISRM) in 1979 in foreign countries. Since my country issued the Chinese Engineering Rock Mass Test Method Standard (GB / T50266-99) in 1999, there has been "Water Conservancy and Hydropower Enginee...

AI Technical Summary

Problems solved by technology

These test procedures are roughly the same, but there are great defects and limitations in the process of disintegration resistance test: the rock sample is disturbed by strong mechanical external force, the test time is short, the water migration in the rock is not complete, and the disintegration of the rock cannot be observed in real time disintegration conditions, and does not conform to the actual disintegration process of rocks

The general disintegration test process is more in line with the actual rock disintegration situation, but under laboratory conditions, manual operation is time-consuming and laborious, with large errors, and it is impossible to continuously measure the particle gradation changes of disintegration products under different conditions in real time, and the disintegration aqueous solution is not easy to recycle. Preservation and other disadvantages; the rock static disintegration process instrument invented by the Institute of Geology and Geophysics, Chinese Academy of Sciences can only measure the mass change of disintegrated materials with different particle sizes under the single condition of rock immersion, and if the buoyancy of water and the relationship between disintegrated materials are considered Due to the effect of cohesion, the measured mass of disintegrated matter with different particle sizes is not the real mass, and the balance reading cannot automatically collect data in real time, and cannot simulate the disintegration of rocks under multiple environmental conditions such as dynamic watering, dry-wet crossover, and temperature changes. and other shortcomings

[0005] Currently on the market and in the existing research, there is no high-simulation test equipment for systematic real-time quantitative continuous measurement of rock disintegration characteristics and evaluation of rock self-sustaining ability under different environmental conditions
