Unconsolidated sampling device and unconsolidated sampling method

摘要

The present invention provides an unconsolidated sampling device and an unconsolidated sampling method capable of simply collecting fluid unconsolidated sediment by descent from an unmanned aerial vehicle or a small boat. An unconsolidated sampling device comprising a sampler 3 and a pulling means for pulling the sampler, the cylindrical sampler body 6 having an opening formed on the bottom, and the inside of the sampler body being slid A possible piston 7, biasing means 8 for biasing the piston to the opposite side of the opening, and locking means 9 for positioning the piston near the opening, when the sampler bottoms on the water bottom, The locking means is released, and the biasing force of the biasing means causes the piston to move to the opposite side of the opening, whereby an unconsolidated sample of the water bottom is sucked into the inside of the sampler body.
