The utility model relates to a device that integrates the multi-tube sampling and columnar sampling functions. The shallow surface sediments and overlying water samples (multiple tubes) were collected with low perturbation, or more deeply stratified undisturbed sediment samples (columnar) were collected. To meet the research needs of Marine engineering geology, biology, chemistry, geoengineering and ecological change. This type of sampling system has been equipped with multiple search and measurement ships, which have carried out several deep-sea operations with the ship.
