TBM excavation rock slag information automatic acquisition and analysis system and method

Abstract

The invention discloses a TBM excavation rock slag information automatic acquisition and analysis system and method. The system comprises a visual sensor used for acquiring rock slag images, a TBM matched belt which is used for transporting rock slag and provided with stripes, a controller which is used for processing the rock slag images to obtain the shape and the size of the rock slag in a slagmaterial, and a TBM operating room display which is used for displaying rock slag information; and the controller is connected with the visual sensor. A manner of arranging a plurality of measuring points on the TBM belt is adopted to obtain more comprehensive and accurate rock slag two-dimensional information, and rock slag three-dimensional characteristics such as the shape, the particle size and the gradation of the rock slag are estimated through processing of the controller, so that an important basis is provided for judging the geological condition of surrounding rock and adjusting TBMtunneling parameters according to the rock slag characteristics. By means of the system and method, the problems that an operator cannot timely and comprehensively observe the surrounding rock condition and time and labor are wasted when the rock slag is manually screened are solved, and the rock slag images can be collected and analyzed in real time so that tunnel face rock mass information can be timely provided.

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.
