Oil-Operated Fixed-Piston Sampler and Its Applicability
Publication: Journal of Geotechnical and Geoenvironmental Engineering
Volume 139, Issue 1
Abstract
This paper presents the development of an oil-operated fixed-piston sampler. This sampler includes a vacuum breaker, which prevents the suction between the sample and piston during disassembly, and an improved version of a complex system used for continuous advancement in mechanical samplers. The improvement makes the new sampler easy to operate, similar to the hydraulic sampler. The oil-operated and hydraulic samplers were used at a site in the Nakdong River Delta. Suction, shear-wave velocity, and consolidation tests were performed on 100-mm-long specimens equally divided by the extruded samples, as well as the seismic flat dilatometer and the piezocone tests in the field. The results show that the new sampler gave better sample quality than the hydraulic-type sampler, indicating better recovery ratio. The main difference in sample quality between the two samplers can be attributed to mechanical destructuration, owing to the stepped advancement and the slight tilt of the hydraulic sampler.
