PROBLEM TO BE SOLVED: To provide a piping structure that dispenses with a pump for supplying shaft sealing water and priming water for a sand pump and precludes an interference in piping.;SOLUTION: For the supply of shaft sealing water and priming water to the sand pump 11, a part of water discharged from a jetting/ejecting pump 15 is supplied in branch form, and if necessary, a pressure/flow regulating valve is interposed in the branch piping. For the arrangement of a sand collecting suction pipe 12 and a jetting/ejecting water pipe 18, an interference preventing member is interposed between both pipes to prevent damage to the rubber suction pipe 12 and water pipe 18 both extending outboard.;COPYRIGHT: (C)2003,JPO
