[0003] There are many current methods for testing the compaction of roadbed and pavement projects, mainly including sand filling method, water filling method, knife ring method, wax sealing method, nuclear density meter measurement method, etc. The sand filling method is to drop the sampled sand using a shovel from a certain height into a test hole (cylinder) of a specified volume, and then detect the volume of the test hole (cylinder) based on the principle of constant unit mass.

[0014] (2) The device fixes the sampling tube at one end of the connecting shaft of the portable hand-held motor and installs a sensor inside the sampling tube, so that the sampling tube automatically rotates into the ground to perform sampling.
