SUCTION PIPE FOR UNDERWATER DEPOSIT TRANSPORTATION, TRANSPORTATION DEVICE OF UNDERWATER DEPOSIT AND TRANSPORTATION METHOD OF UNDERWATER DEPOSIT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a suction pipe for underwater deposit transportation, capable of efficiently and stably transporting underwater deposit deposited at a water bottom to another area even when a deposition depth of the underwater deposit is deep, and a transportation device and a transportation method of the underwater deposit using the suction pipe.;SOLUTION: For the suction pipe of this invention, one end of a pipe body 50 is turned to a water intake 2a, the other end is turned to a connection end 51, a turn-back part 52 is formed at the middle part of both ends, and a sheet member 53 is closely attached to the lower part of the turn-back part 52. At the sheet member 53 and a part where the sheet member 53 is closely attached, lower suction holes 54 are consecutively perforated. At the side part of a pipe material corresponding to a distal end 52a of the turn-back part 52 at the upper part of a water surface side from the sheet member 53, a side part suction hole 55 is perforated. Further, on a lower side of an extension part 60 of the pipe material extending from the part where the sheet member 53 is closely attached to the water intake 2a, a plurality of suction assisting holes 61 are arranged side by side in the extension direction.;COPYRIGHT: (C)2013,JPO&INPIT
