specific Embodiment

[0026] Concrete embodiment: a kind of method adopting waveform method to analyze the second row of reinforcement position of mining method tunnel, it is characterized in that its steps are:

[0027] (1) Using the sir-3000 main engine and ground penetrating radar with 900MHz antenna of GSSI company in the United States to collect data on the secondary lining of mining tunnels;

[0028] (2) Use "Radan7" software to open the aerial data of the antenna and determine the ground zero point of the antenna;

[0029] (3) Click the "Process" button in the "Home" tab of the software to process the data;

[0030] (4) During data processing, right-click on the ordinate of the data file, and click "Sample" under the vertical scale on the pop-up menu bar;

[0031] (5) Click the "Window Settings" button in the "Home" tab, and at the same time, it can be seen from the data interface that the ground reflection waves are distributed between 80-120 samples;

[0032] (6) In the opened "Propertie...

Abstract

The invention relates to the technical field of steel bar locating in secondary lining of mined tunnels, in particular to a method for analyzing the position of a second row of steel bars in a mined tunnel by adopting a waveform method. When the position of the second row of the steel bars in the mined tunnel is analyzed by adopting the waveform method, a ground penetrating radar is adopted to perform data collection on secondary lining of the mined tunnel; during analysis by adopting the waveform method, in the position of a first row of steel bars, the amplitude is a maximum value; and with the increment of the depth, the amplitude of a radar wave is gradually reduced when the radar wave does not meet the second row of the steel bars, and the amplitude of the radar wave is remarkably increased when the radar wave meets the second row of the steel bars, so that it is showed that the second row of the steel bars are arranged in the position where the amplitude is increased. According to the method for analyzing the position of the second row of the steel bars in the mined tunnel by adopting the waveform method, data is analyzed, so that the position of the second row of the steel bars in the mined tunnel can be accurately displayed and the demands of people on locating of the position of the second row of the steel bars in the mined tunnel can be met; and the method is suitable for population and use.

Description

technical field [0001] The invention relates to the technical field of steel bar positioning in tunnels, in particular to a method for analyzing the position of the second row of steel bars in mine tunnels using a waveform method. Background technique [0002] When using ground penetrating radar to inspect the secondary lining of mining tunnels, the relatively dense steel bars distributed in the lining have a certain shielding effect on radar waves, and at the same time, the reflection signal of the first row of steel bars has a significant effect on the reflection signal of the second row of steel bars. A certain cover-up. Therefore, when actually measuring the position of the second row of steel bars in the tunnel, there are certain difficulties in determining the position of the second row of steel bars in the secondary lining. [0003] The invention relates to a method for analyzing the position of the second row of steel bars in a mining tunnel using the waveform metho...
