Calculation of Resistance to Motion of TK-1 Press Piston Sampler and Marine Sampling Test

Abstract:

The press piston sampler was firstly used for marine sampling sand and soil. By the scientific simulation calculation of sampler, the resistance to motion and the pressure to force into formation were obtained. The test shows that the data accorded with actual marine sampling situation; and the designed sealing device, turnover sampler and PC sampling tube can satisfy the requirements of marine sampling.
