Description

Technical Field

[0001] The utility model relates to the field of engineering test tools, in particular to a protective device for a geological radar antenna and a geological radar antenna. Background Art

[0002] During the construction of tunnels, geological radar is used to detect the quality of tunnels. Geological radar can non-destructively detect the thickness of the tunnel secondary lining and promptly detect internal defects of the tunnel secondary lining. The tunnel secondary lining has high requirements for the density of concrete. When the high-speed railway passes through the tunnel, it will generate a strong negative pressure, which will suck the surrounding objects in the tunnel into the carriage. Therefore, after the tunnel secondary lining is poured, the loose concrete at the corners of the tunnel secondary lining will be chiseled off, especially at the joints of the secondary lining construction plates, which is the most obvious, resulting in a large gap between the adjacent tunnel secondary lining plates. The structure of the geological radar antenna is as follows: Figure 1 shown.

[0003] However, due to the large spacing between the plate joints of the tunnel's secondary lining, the geological radar antenna will collide with the concrete during the tunnel inspection process, affecting the service life of the geological radar antenna. Severe collisions will cause direct damage to the geological radar antenna. Utility Model Content
