Tunnel surrounding rock rapid grading equipment system and operation method thereof

Abstract

The invention relates to the technical field of tunnel engineering and further discloses a tunnel surrounding rock rapid grading equipment system and an operation method thereof. The tunnel surrounding rock rapid grading equipment system is mainly composed of three parts of software and hardware including a rock mass integrity coefficient rapid test and analysis module, a rock uniaxial saturated compressive strength rapid test and analysis module and a surrounding rock grading correction index test and analysis module. The invention discloses a tunnel surrounding rock rapid grading equipment system and an operation method thereof. A set of integrated tunnel surrounding rock grade rapid identification equipment system integrating acquisition, storage, calling, input, calculation and resultoutput is developed for the first time in the field of surrounding rock grading. The method has the characteristics of high resolution, low energy consumption, portability and function integration, has the characteristics of dust prevention, moisture prevention, interference prevention and the like, is more suitable for being applied to severe environments in tunnel holes, realizes the rapidness,quantification and standardization of tunnel surrounding rock classification, and avoids the problems of subjectivity of artificial identification, lack of operability of conventional identification and the like.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a tunnel surrounding rock rapid classification equipment system and an operating method thereof. Background technique [0002] Tunnel engineering is a high-risk concealed project. The surrounding rock classification provided by the conventional survey in the early stage for tunnel engineering design is a rough pre-classification of the surrounding rock, which needs to be continuously corrected during the construction process. However, there are hundreds of engineering rock mass classification methods proposed by scholars at home and abroad, and the surrounding rock classification methods of roads and railways currently used in China are not the same, and the number of quantitative indicators selected by each classification method is different, ranging from 1 , up to nearly 10. At present, it is not uncommon for tunnel and underground engineering construction geologica...

AI Technical Summary

Problems solved by technology

The conventional surrounding rock classification method is very slow and has many qualitative factors. It lacks a rapid classification method for the tunnel surrounding rock during the construction period. In addition, it is difficult to collect and analyze quantitative index parameters. The current surrounding rock classification during the construction period is mainly carried out at the tunnel site. Judging immediately by observation, subjective assumptions, and lack of scientificity, so there are more collapse disasters caused by wrong division of surrounding rocks, resulting in a lot of loss of life and property
