Title:
未固結試料採取装置及び未固結試料採取方法
Document Type and Number:
Japanese Patent JP6928925
Kind Code:
B2
Abstract:
To provide an unsolidified specimen sampling device which can easily sample fluidity unsolidified deposits falling from an unmanned aircraft or a small-sized boat, and an unsolidified specimen sampling method.SOLUTION: An unsolidified specimen sampling device composed of a sampler 3 and traction means for towing the sampler is constituted of: a cylindrical sampler main body 6 in which an opening part is formed at a bottom face; a piston 7 slidable in the sampler main body; energization means 8 for energizing the piston to a side opposite to the opening part; and lock means 9 for locating the piston in the vicinity of the opening part. When the sampler is landed on a water bottom, the lock means is released, the piston is moved to a side opposite to the opening part by an energization force of the energization means, and an unsolidified specimen at the water bottom is thereby absorbed into the sampler main body.SELECTED DRAWING: Figure 1
