Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, and in particular to a compaction testing device carrying a ground penetrating radar sensor. Background Technology

[0002] A compaction tester is a device specifically designed to test the compaction of backfill. It is widely used in engineering fields such as construction, roads, and water conservancy. By using a compaction tester, the compaction of backfill can be quickly and accurately determined, thus providing a reliable basis for controlling construction quality.

[0003] Current compaction testing devices typically require excavating the topsoil layer for compaction testing, which can damage areas that have already been constructed or need to be preserved, and may also damage completed road structures. Furthermore, traditional testing methods require a long time for sampling and testing, which is not conducive to improving work efficiency.

By incorporating this radar detection structure, the compaction information of the fill can be obtained without excavation or damage during use. This is crucial for completed or unfinished fill areas and can provide continuous images of the fill's internal structure, clearly showing the distribution of different compaction areas, thus facilitating a comprehensive understanding of the overall quality of the fill.
