It is an important technical means in geological exploration. A drilling rig is used to drill from the surface downward to form a cylindrical borehole in the stratum to identify and divide the strata. After the drilling is completed, a drill hole will be left, which needs to be backfilled and compacted. The existing geotechnical engineering survey drilling hole backfill compaction device can only rely on the weight of the roller to compact the backfill ground when in use. Some gravel in the soil body may not be broken well, resulting in insufficient compaction of the backfill, gaps between the soil bodies, and uneven ground. Utility Model Content
