The endoscope for measuring the underground cavity comprises an endoscope host, a coil pipe and a lens, one end of the coil pipe is connected to the endoscope host, the outer side wall of the coil pipe is provided with size scales extending in the axial direction of the coil pipe, the lens is arranged at the other end of the coil pipe, and the lens is used for photographing and recording the underground cavity. Due to the fact that the cavity top burial depth and the cavity bottom burial depth are directly read through the size scales on the coil pipe, marking on the coil pipe of an endoscope is not needed, the defect that marks are possibly not clear enough or marking positions have errors does not exist naturally, and the clear height of the cavity can be accurately obtained. In addition, when an endoscope photo or video is shot, the top burial depth and the bottom burial depth of the cavity can be directly read through the size scales on the coil pipe, the cavity clearance is calculated, and therefore the
