[0002] During the construction of municipal buildings, it is necessary to pound the construction ground to ensure the construction requirements of foundation compaction. The tamping machine tamps the foundation soil with strong impact energy, causing shock waves and large impact stresses in the soil, forcing the voids in the soil layer to be compressed and the soil materials to be rearranged to achieve consolidation, thereby increasing the bearing capacity of the foundation to withstand the upper load. After the foundation is compacted, a compaction degree detection device is usually required to detect whether the compaction degree of the foundation is qualified.
