PURPOSE:To facilitate adjusting of specific gravity of capsule by providing an air chamber having one to several downward openings in a capsule then injecting air fed from the outside of tube into the tube to said chamber. CONSTITUTION:In a system where soil or other content contained in a load chamber 1 of capsule A is water transported together with capsule A, air chambers 2 having a notch section 3 at the lower portion are provided at both ends of capsule. When adjusting specific gravity of capsule A, air to be fed through a nozzle 5 provided at predetermined position of water tube and an air tube 4 is injected into an air chamber 2 of capsule A. Here overflow of air is discharged through strainer 6, exhaust chamber 7 and exhaust valve 8. |
