CONVEYING EQUIPMENT FOR SOLID-LIQUID MIXED FLUID, DREDGE UNIT FOR SEDIMENT IN DAM LAKE, AND CONVEYING METHOD FOR SOLID-LIQUID MIXED FLUID

摘要

PROBLEM TO BE SOLVED: To provide conveying equipment for a solid-liquid mixed fluid, which can stably perform the short-distance and long-distance conveyance of the solid-liquid mixed fluid, without causing the accumulation of the solid-liquid mixed fluid in a pipe, by a simple structure, a dredge unit for sediment in a dam lake, and a conveying method for the solid-liquid mixed fluid.;SOLUTION: The conveying equipment for the solid-liquid mixed fluid internally passes in the longitudinal direction of a rigid conduit with a lead-in port for the solid-liquid mixed fluid, and a long thin shape-restorable bent plate of an elastic material is held inside. The solid-liquid mixed fluid led into the rigid conduit via a propulsion and driving means is propelled and driven in the longitudinal direction of the rigid conduit. The solid-liquid mixed fluid is conveyed through the rigid conduit while the non-accumulation of the solid-liquid mixed fluid in the pipe via the elasticity restoration action of the long thin shape-restorable bent plate of the elastic material is maintained. The occurrence of the bridge of the solid-liquid mixed fluid in the pipe is prevented so that the stable conveyance in the pipe can be secured.;COPYRIGHT: (C)2009,JPO&INPIT
