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

Embodiment 1

[0042] In a typical embodiment of the present invention, such as Figure 1-Figure 3As shown, a TBM slag slag ray backscatter real-time scanning imaging device 11 includes a bracket 4 that can be arranged across a TBM conveyor belt 9 for transporting slag chips 8 .

[0043] The TBM conveyor belt 9 has a set length, and the TBM conveyor belt 9 is supported by a pillar, so that the TBM conveyor belt 9 has a set height. The bottom of the support 5 is supported by a pillar, and the bottom of the pillar is arranged on the ground, and the fixed support 5 is connected with the support 4 through bolts.

[0044] In some embodiments, in order to realize that the support 4 drives the movement of the radiation-proof housing 2 relative to the fixed support 5, a slider is provided at the bottom of the support 4, and a slide rail is provided at the fixed support 5, and the slide block cooperates with the slide rail to realize radiation protection. The movement of the shell 2 relative to the ...

Embodiment 2

[0052] A kind of TBM slag sheet ray backscatter real-time scanning imaging analysis method, adopts a kind of TBM slag sheet ray backscatter real-time scanning imaging device described in embodiment 1, comprises the following contents:

[0053] When starting to scan, open the slide switch door 6, again as figure 2 As shown in , the X-ray tube 3 and the detection receiver 10 are arranged along the transmission direction of the belt conveyor at one time. As the TBM conveyor belt moves, the X-ray tube 3 is excited, and the detection receiver 10 receives the corresponding number of Compton scattered photons from different positions , X-ray backscattering can carry out large-area and single-sided scanning, because there is no limitation of post-part imaging equipment, and it is convenient for mobile scanning, small in size and small in working space. It is very consistent, and the device is real-time, and can feed back the scanning results to the TBM driver in a relatively short pe...

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...
