Especially when dealing with large-area dynamic compaction foundation, it is often difficult to ensure the detection efficiency and accuracy. Therefore, it is particularly important to develop a detection device with simple structure, convenient operation, and applicable to the quality and safety of large-area dynamic compaction foundation;
