SAND DISCHARGE DEVICE, AND SAND DISCHARGE METHOD
To improve sand discharge efficiency in a sand discharge device.SOLUTION: A sand discharge device 1 comprises: a suction portion 5 placed on water bottom and sucking up accumulated sediment 9; a transport pipe 6 connected to the suction portion 5 and transporting the sucked-up sediment to a predetermined discharge position; and a moving portion 3 moving the suction portion 5 in a predetermined traveling direction A1 when the suction portion 5 sucks up the accumulated sediment 9. A front surface 522 of the suction portion 5 facing a front side in the traveling direction A1 includes an inclined surface 523 inclined from a lower side to an upper side toward the front side in the traveling direction A1. Suction holes 510, 520 for the accumulated sediment 9 are provided in a bottom surface 513 and the inclined surface 523 of the suction portion 5, respectively. This makes it possible to improve sand discharge efficiency in the sand discharge device 1.SELECTED DRAWING: Figure 1
【課題】排砂装置における排砂効率を向上する。【解決手段】排砂装置１は、水底に配置され、堆積土砂９を吸引する吸引部５と、吸引部５に接続され、吸引された土砂を所定の排出位置まで輸送する輸送管６と、吸引部５により堆積土砂９を吸引する際に、吸引部５を所定の進行方向Ａ１に移動する移動部３とを備える。吸引部５において進行方向Ａ１の前側を向く前方面５２２が、下側から上側に向かって進行方向Ａ１の前側に傾斜する傾斜面５２３を含む。吸引部５の底面５１３および傾斜面５２３のそれぞれに、堆積土砂９の吸引孔５１０，５２０が設けられる。これにより、排砂装置１における排砂効率を向上することができる。【選択図】図１
