The invention provides an underground cavity detection system, aiming to solve the problem that the detection depth and resolution requirements cannot be met simultaneously in the prior art. The underground cavity detection system comprises: a signal transmitting device for transmitting multiple channels of detecting signals different in frequency to the ground surface of a measured area; a signal receiving device for obtaining multiple channels of reflection echo signals corresponding to the multiple channels of detecting signals; and an acquisition device connected to a signal receiving device and used for receiving the multiple channels of reflection echo signals and converting the multiple channels of reflection echo signals into echo data, respectively. With the technical proposal provided in the invention, the reflection echo signals of the multiple channels of detecting signals different in frequency reflected by various underground layers of mediums can be utilized to detect underground cavities; and the detection depth can be guaranteed by utilizing a low-frequency signal while relatively high resolution can be obtained by utilizing a high-frequency signal; therefore, the detection depth and resolution requirements can be met simultaneously.
Description
technical field [0001] The invention relates to a detection field, in particular to an underground cavity detection system. Background technique [0002] With the rapid growth of my country's economy for many years, the pace of urban road construction, subway construction and underground space development is accelerating, and urban vehicles have increased dramatically. At the same time, due to reasons such as heavy road traffic, aging pavement, subsidence of subgrade, rain erosion, water seepage on the pavement, leakage of underground pipes, etc., holes appear in the underground subgrade of the road, which leads to problems such as cracking, deformation, subsidence and subsidence of the pavement. It is particularly important to actively carry out the detection and control of urban road diseases and reduce the traffic problems caused by road diseases through effective underground cavity detection methods. [0003] Ground-penetrating radar is mainly used in the detection of u...
