TK-1型压入活塞式取样器运动阻力计算及海上取样试验

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

摘要:

在海上采用压入活塞取样器取砂、土样在国内尚属首次。经过对取样器进行科学的模拟计算，获得了取样器运动阻力和压入地层所需的压力，试验表明，这些数据符合海上取样的实际情况。所设计的密封装置、翻板取样器及PC取样管等满足了海上取样要求。

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.
