Abstract
PURPOSE: To obtain an appratus by which more accurate N value is obtained by lowering tube with built-in sampler using wire to the sea bottom, and striking the sampler into the bottom by dropping weight on it within the glass chamber at the sampler.
CONSTITUTION: Inner tube 20 which is consisted of water pressure chamber 24 and sampler container 26 is hung underwater by wire 18, while sampler 28 containing split tube 32 and weight 36 is disposed slidably within the container 26. Latch rod 38 is provided with guide 40 positioned within the pressure chamber 24 at one end and weight 36 and latch 42 at the other end. By the increased pressure at the pressure chamber 24, rod 38 is lowered and catches the weight 36 by the latch 42, then, the weight 36 is brought upward by the increase of gas pressure at the gas chamber 30, and the tube 32 is penetrated into the bottom by releasing the catch of the weight.
