To find the interface of concrete and slurry in a cast-in place pile, the numerical simulation method and Laboratory tests are performed. Pressures along a pipe were obtained. Differential pressures of fixed distance were calculated. Differential pressure curves were plotted. The result shows that pressure along a pipe is differ. Differential pressure remains constant in certain mediums but changes across different mediums. The interface of concrete and slurry can be found from differential pressure plots. If transducers whose number is at least two can be tied on a fixed place of pipe, differential pressure will be obtained by pulling pipe out gradually, and the interface of the concrete and slurry will be found easily. This is useful for keeping pipe under concrete and ensuring pipe quality.
