A system and method for automatic collection and analysis of tbm excavation rock slag information

Abstract

The invention discloses a system and method for automatically collecting and analyzing information on rock slag excavated by a TBM. The system includes: a visual sensor for collecting images of rock slag; a TBM supporting belt for transporting rock slag, and the belt is provided with stripes; A controller used to process rock slag images to obtain the shape and size of each rock slag in the slag material; a TBM operating room monitor used to display rock slag information, and the controller is connected to the visual sensor. The method of arranging multiple measuring points on the TBM belt is used to obtain more comprehensive and accurate two-dimensional information of the rock slag. Through the processing of the controller, the three-dimensional characteristics of the rock slag such as the shape, particle size and gradation of the rock slag are estimated. Furthermore, it provides an important basis for judging the geological conditions of the surrounding rock and adjusting the TBM tunneling parameters according to the characteristics of rock slag. The invention solves the problems that operators cannot observe the surrounding rock conditions comprehensively in time and manually sieves rock slag, and can collect and analyze rock slag images in real time so as to provide face rock mass information in time.

Description

technical field [0001] The invention relates to the technical field of a tunnel boring machine (TBM), an automatic rock slag information collection system and a rock slag information analysis system, in particular to an automatic collection and analysis system and method for TBM excavation rock slag information. Background technique [0002] With the construction of my country's infrastructure, railways, highways, South-to-North Water Diversion and West-East Gas Transmission projects, full-face tunnel boring machines (TBMs) are widely used in deep-buried long tunnels due to their safety, efficiency, economy, and environmental protection. construction. [0003] During the TBM excavation process, it is necessary to judge the type and quality of the surrounding rock according to the geological conditions of the surrounding rock, so that it is convenient to select the appropriate TBM excavation parameters and surrounding rock support form according to the type and quality of the ...

AI Technical Summary

Problems solved by technology

[0006] However, judging from the current testing technology of tunnel surrounding rock geology, the collection and analysis of TBM excavation rock residue information cannot be accurate and fast.

The existing technology only uses a high-speed camera to take pictures above the belt, and the shape and size of the obtained rock slag are only two-dimensional parameters, which is relatively one-sided; using the traditional screening method to test the rock slag takes a long time and cannot be obtained in real time.
