SAND LIFTING AND CONVEYING METHOD AND SAND LIFTING AND CONVEYING DEVICE
PROBLEM TO BE SOLVED: To provide a sand lifting and conveying method and a sand lifting and conveying device where the pneumatic conveyance efficiency of deposited sediment is improved, operation is simplified, the deposited sediment can be recovered in high concentration and pollution in water is suppressed.SOLUTION: In a sand lifting and conveying device, ambient air flows from an ambient air communication pipe 12 due to negative pressure generated by a vacuum generating device 20, compressed air is supplied from a blower pipe 16 to the ambient air communication pipe 12 at a bottom in water, an air stream flowing from a portion of a pipe body 4 disposed with at least a sediment suction port 36 toward one end of the pipe body 4 in a longitudinal direction is formed; deposited sediment 34 is continuously sucked by the air stream from the sediment suction port 36 with water at the bottom in water, sucked water and the deposited sediment 34 are continuously conveyed to a sediment recovery part 38 via a pneumatic conveyance pipe 14, and the water and deposited sediment 34 are recovered by the sediment recovery part 38 and discharged from the sediment recovery part 38 to the platform of a dump truck 42.SELECTED DRAWING: Figure 1
【課題】堆積土砂の気流搬送効率を高めると共に、作業の簡素化を図り、堆積土砂を高濃度に回収でき、水中の汚濁化を抑制する。【解決手段】真空発生装置２０によって発生する負圧により大気が大気連通管１２から流入し、また、ブロワ管１６から水中の底部において圧縮空気が大気連通管１２に供給され、少なくとも土砂吸引口３６が設けられた管体４の箇所から管体４の長手方向の一端に向かう気流が生成される。この気流により水中の底部において水と共に堆積土砂３４が土砂吸引口３６から連続的に吸入され、吸入された水と堆積土砂３４は気流搬送管１４を介して土砂回収部３８へ連続的に搬送され、水と堆積土砂３４は土砂回収部３８により回収され、土砂回収部３８からダンプトラック４２の荷台に排出される。【選択図】図１
