Patent No：200910082851.4

Patent No：200810240908.4

Test principle and method

The automatic excitation device excites the pulse signal at the cross section of the column head, and reflects at the other end of the column. The elastic wave propagation time is calculated by the signal analysis software, and the buried depth is obtained by combining the actual elastic wave velocity.
