. Technical background
With the development of cities, engineering construction such as roads, subways and underground structures develop rapidly, and secondary disasters such as road collapse occur frequently. The demand for services such as engineering geological survey and engineering disaster diagnosis is increasing day by day, and the depth of detection required has increased from 3. Seismic and electrical prospecting not only have low resolution, but are also difficult to adapt to the harsh environment of urban roads and traffic. Although the resolution of geological radar is very high, the detection depth is too shallow, making it difficult to meet actual engineering needs. At present, depth detection in cities is still a blank in the field of engineering geophysical prospecting. Technology was developed to fill this gap.
3. Technical features
). High resolution and large detection depth: vertical resolution up to 100%, equivalent to radar detection depth, equivalent to times of radar detection depth
). Strong anti-interference ability , no need to interrupt traffic
). Tow cable reception, no damage to the road surface, fast detection
). Real-time imaging, on-site scanning imaging, immediate discovery of geological problems
Dark blue area (drawing border) are the locations that require grouting and reinforcement.
Technical advantages of cavity detection system
Technical performance advantages
In the field of engineering geophysical prospecting, the resolution of geological radar is the highest, and the exploration depth of reflection seismic is the largest. For urban detection targets, it has more advantages than seismic and geological radar. The resolution is one order of magnitude higher than seismic, and the detection depth is one order of magnitude higher than georadar. Performance comparison is shown in the table below.

As can be seen from the above table, the resolution is equivalent to that of geological radar, but the detection depth is - times that of geological radar. This is the charm.
