[0003] When cracks appear in the tunnel, they need to be checked and tested to ensure safe operation of the tunnel.

[0004] After searching: ① Application No. / Patent No. 201720290327.6 discloses a portable tunnel crack observation device, including a first support rod, a display device and an electron microscope for observing tunnel cracks. The front end of the electron microscope is provided with an omnidirectional scale for measuring the size of the tunnel cracks. The electron microscope is connected to the end of the first support rod through a connecting hinge that can adjust the orientation of the electron microscope. The electron microscope is also connected to the display device for reading the width of the tunnel crack through a data cable. The device can fully combine people and equipment, has a simple structure, is easy to use and simple to operate, and has relatively low cost.
