Problems solved by technology

[0002] Ground-penetrating radar testing technology is a method that uses the reflection of high-frequency electromagnetic pulse waves to detect the distribution and characteristics of underground objects; at present, ground-penetrating radar has been widely used in the quality inspection of water conservancy projects and included in the specifications, and has achieved good results. effect; in addition, cracks and holes are also common safety hazards of dams. Generally, they are caused by the different degrees of soil compaction of the dams, or the poor contact of different media in the dams, and the long-term flow and erosion of pore water; local collapse, water erosion, ant Phenomena such as cavitation can also lead to the formation of cavities inside the embankment, especially during floods, or the special form of cavities—piping, which poses the greatest threat to the embankment. Hidden dangers are commonly used technical means at present, and artificial naked eyes can only see hidden dangers on the surface, and hidden dangers such as termites in internal cracks and cavities are often uncertain. Ground penetrating radar uses the propagation and reflection characteristics of electromagnetic waves in different media to detect underground It is a high-tech developed in the past ten years. It is characterized by high resolution, accurate positioning, high work efficiency, convenient operation and non-destructive testing. method, is gradually becoming a powerful tool for engineering testing
[0003] At present, the common methods of ground-penetrating radar detection for dams are as follows: 1. Place the ground-penetrating radar detection device on the surface of the dam to be tested, and manually drive the ground-penetrating radar detection device to move on the surface of the dam by pulling the rope to carry out the dam inspection. 2. Fix the ground penetrating radar detection device on the auxiliary trolley, and then manually push the trolley for detection; however, since the embankment is generally a slope with a certain angle, people have to walk or push the cart when performing detection operations. It is extremely inconvenient. When encountering wet and slippery slopes and embankments with large slopes, there is also the risk of the operator slipping and falling into the water and the detection device rolling over. In addition, due to the large length and width of the embankment, it is generally tens of meters to hundreds of meters. Meters vary, manual work is labor-intensive, and inspection work is time-consuming

Abstract

The invention discloses an auxiliary device of a ground penetrating radar. The device comprises a walking device, a detection trolley and a ground penetrating radar device, wherein the walking deviceand the detection trolley are connected through a cable, the ground penetrating radar device is installed on the detection trolley, the detection trolley is dragged through the cable, the ground penetrating radar device is slowly moved from the dam to the position below the dam for detection operation, and the problem that slope walking is inconvenient during manual operation is solved; meanwhile,spiral fans are designed at the front end and the rear end of the detection trolley, the detection trolley can be better attached to a steep slope and a dam through additional thrust generated by thespiral fans and is not prone to rollover, when the detection trolley conducts detection on a straight wall through the additional thrust of the spiral fans, the detection trolley can be kept attachedto the wall face all the time, and a detection task can be better completed.
