Embodiment Construction

[0014] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0015] as attached figure 2 As shown, a system for detecting the height of the second lining of a tunnel based on thermal imaging includes a thermal imaging camera 1, a tunnel trolley 2 and a heat source 4, and the window 21 on the outer surface of the tunnel trolley 2 is closely covered on the inner wall of the tunnel On the surface of the reinforced frame 3, the concrete is continuously conveyed along the pipeline through the concrete delivery pump truck using pressure during pouring, and then the concrete is poured into the reinforced frame 3 between the tunnel trolley 2 and the inner wall of the tunnel through the distributing machine and the chute from the window 21 Carry out the second lining of the tunnel.

[0016] as attached figure 2 As shown, the thermal imaging camera 1 is movable inside the tunnel trolley 2 , and the thermal imaging camera...

Abstract

The present invention relates to the field of tunnel construction, and particularly refers to a system and method for detecting the height of tunnel secondary lining fabric based on thermal imaging, which includes a thermal imaging camera, a tunnel secondary lining trolley and a heat source. The advantage of the present invention is that the thermal imaging camera is used to receive data from the tunnel. The template and heat source of the secondary lining trolley emit energy in the infrared wavelength spectrum and process the infrared energy to generate a thermal image. Image processing and analysis software is then used to filter, corrode and threshold segment the thermal image to improve the quality of the thermal image. , get a clear high-temperature area of ​​the concrete being poured, and then calculate the height of the concrete being poured from the ground, and understand the progress of the second lining pouring and distributing in real time, which facilitates the control and switching of the distribution machine and the switching of different pouring windows without the need for workers to hold their heads. Reaching into the window for observation can reduce workers' workload, eliminate potential safety hazards, ensure workers' safety, and provide necessary conditions for realizing fully automatic construction of the second lining.

Description

technical field [0001] The invention relates to the field of tunnel processing, in particular to a system and a detection method for detecting the height of the second lining of a tunnel based on thermal imaging. Background technique [0002] The concrete for the secondary lining of the tunnel uses the integral hydraulic tunnel trolley as the formwork. After being transported to the site by the concrete transport tanker, it is layered from bottom to top through the concrete delivery pump, and the concrete is poured from the poured section in the direction of the entrance to the tunnel surface using the chute and the pouring window. It is poured layer by layer symmetrically from left to right, and when pouring layer by layer, it is necessary to ensure that the second lining on the lower layer is poured before continuing to pour the second lining on the upper layer. The perfusion window is observed with flashlight lighting, which increases the workload of workers and has certa...
