The ground penetrating radar walking device comprises a supporting sliding plate, a firsttransverse suction cup assembly, a second transverse suction cup assembly, a first longitudinal suction cup assembly, and a second longitudinal suction cup assembly, wherein the first transverse suction cup assembly and the second transverse suction cup assembly are connected with the supporting sliding plate through a first transverse guide rod and a second transverse guide rod, and the first longitudinal suction cup assembly and the second longitudinal suction cup assembly are connected with the supporting sliding plate through a first longitudinal guide rod and a second longitudinal guiderod; and the ground penetrating radar walking device further comprises a transverse telescopic cylinder and a longitudinal telescopic cylinder, wherein the transverse telescopic cylinder and the longitudinal telescopic cylinder are fixed to the supporting sliding plate, through cooperation of the transverse telescopic cylinder and the longitudinal telescopic cylinder, the transverse suction cup assemblies and the longitudinal suction cup assemblies transversely and longitudinally walk on the wall surface, and a ground penetrating radar detection device is fixed to the bottom of the ground penetrating radar walking device for detecting the geological condition of the dam body vertical wall surface. The ground penetrating radar walking device is high in automation degree and high in workingefficiency, and the risk of manual operation is decreased.

Description

technical field [0001] The invention relates to the field of ground-penetrating radar detection, in particular to a ground-penetrating radar traveling device for detecting the vertical wall surface of a dam. Background technique [0002] Ground-penetrating radar is a fast, convenient and non-destructive detection technology that does not damage the dam body. It has good detection results for the poor geological conditions of the dam body. At present, ground-penetrating radar has been widely used in the quality inspection of water conservancy projects and incorporated into specifications, and achieved good results. [0003] At present, the methods of non-destructive testing of the vertical wall of the dam by ground penetrating radar are as follows: 1. Place the ground penetrating radar detection device on the surface of the dam body through the traction rope and move it to detect the dam; 2. Fix the ground penetrating radar detection device On the lifting device, the lifting...

[0003] At present, the methods of non-destructive testing of the vertical wall of the dam by ground penetrating radar are as follows: 1. Place the ground penetrating radar detection device on the surface of the dam body through the traction rope and move it to detect the dam; 2. Fix the ground penetrating radar detection device On the lifting device, the lifting device is fixed at the bottom of the dam body or the operator at the bottom of the dam body lifts the lifting device for detection; During the process, the ground penetrating radar detection device cannot always keep a good fit with the wall surface, which affects the measurement results; in addition, the detection through the lifting device fixed at the bottom of the dam body or manual methods requires transporting equipment and people to the dam. It is very inconvenient to work at the bottom for a long time, and the environment at the bottom of the vertical wall of the embankment is relatively harsh, and the safety risk is relatively large; at the same time, due to the large length and width of the embankment, it generally ranges from tens of meters to hundreds of meters , the labor intensity of manual work is high, and the detection work is time-consuming
