Development and Application of Marine Impact Telescopic Sampler
-
Abstract
Marine sediment stratum is mainly composed of silt, soft soil, semi-concreted mudstone and sandstone, the sedi-ment stratum sampling is an important part of marine engineering and geological survey.The original state of sample is easy to be disturbed by the use of conventional rotary sampler with low sampling rate;while by static pressure sampler, the sam-pling rate is not ideal in sandstone and semi-concreted mudstone.According to the above situation, combining the charac-teristics of static pressure sampler and hammering sampler, an impact telescopic wire-line coring sampler was developed to realize truly-preserving sampling in submarine sedimentary bed mainly consisting of sediments.-
