TBM slag sheet ray back scattering real-time scanning imaging device and method

Abstract

The invention discloses a TBM slag sheet ray back scattering real-time scanning imaging device and method, and solves the problems that in the prior art, the appearance condition of a slag sheet can only be obtained on site, the mechanical analysis of the slag sheet is tedious, and the time consumption is long; the device has the beneficial effects that continuous operation can be realized, and the internal and external characteristics of the slag sheet can be obtained in real time; the scheme is as follows: according to the TBM slag sheet ray back scattering real-time scanning imaging deviceand method, the device comprises supports, an X-ray back scattering scanning probe and a computing terminal, wherein the supports are capable of crossing a TBM conveyor belt or are arranged on two sides of the TBM conveyor belt; the X-ray back scattering scanning probe which is arranged in the shell, the shell is supported by the supports, and the shell can be arranged above the TBM conveyor belt,and the X-ray back scattering scanning probe is used for detecting the slag sheet conveyed by the TBM conveyor belt and receiving the data information; and the X-ray back scattering scanning probe isconnected with the computing terminal, and the computing terminal receives data information received by the X-ray back scattering scanning probe, so that the size and shape of the slag sheet and theinternal characteristics of the slag sheet are obtained.

Description

technical field [0001] The invention relates to the field of geotechnical engineering, in particular to a TBM slag slice ray backscatter real-time scanning imaging device and method. Background technique [0002] With the large-scale development of my country's infrastructure construction, the rapid and sustainable development of the national economy urgently requires the construction of a large number of major lifeline projects such as water conservancy, transportation, and mines. The highway, railway, passenger and freight lines continue to extend to the west, and the development scale of underground projects continues to expand. In the future planning of the country, many major underground projects will be built in the central and western regions, while the western regions are mountainous and hilly, and they are buried deep in the construction of large projects. Tunnels play a vital role. The full-face hard rock tunnel boring machine (TBM) construction tunnel has the adv...

Problems solved by technology

[0003] However, for the current methods of obtaining rock mass parameters and surrounding rock grades, the inventors found that the main problems they faced include "long acquisition period, low efficiency, low accuracy rate", etc. Specifically, there are the following problems:

[0004] (1) To obtain more accurate rock mass parameters, it is necessary to drill rock cores on site, and perform mechanical parameter testing experiments indoors after processing and cutting. The process is cumbersome and time-consuming. dynamic needs

[0005] (2) When the belt conveyor is transporting slag, send personnel to conduct on-site inspection and analysis. Due to the influence of the on-site operating environment, it is difficult, and manual analysis cannot continue to work

[0006] (3) A high-speed camera is installed on one side of the belt conveyor. At present, the existing high-speed camera analysis technology for slag flakes can only record the appearance information of the slag flakes on the surface, but cannot detect the internal conditions of the flakes
