WATER BOTTOM SEDIMENT REMOVAL DEVICE AND WATER BOTTOM SEDIMENT REMOVAL METHOD
PROBLEM TO BE SOLVED: To provide a water bottom sediment removal device and a water bottom sediment removal method which can transfer sediment smoothly at any position of a sediment transfer pipe and which can remove sediment having large layer thickness.SOLUTION: In a water bottom sediment removal device, in a sediment transfer pipe, a plurality of sediment inflow ports and a plurality of water jetting ports are arranged in a longer direction, and water flow is generated in the sediment transfer pipe by a suction pump mounted on a substantially center portion of the sediment transfer pipe while water is jetted from the water jetting ports, so that sediment is made to flow into the sediment transfer pipe from the sediment inflow ports while the sediment is discharged to the outside by being carried on the water flow. In the water bottom sediment removal device, the sediment transfer pipe has a nearly V-shape around the fitting position of the suction pump with the projection side of the V-shape set downward.SELECTED DRAWING: Figure 1
【課題】土砂移送管のどの位置であっても円滑に土砂の移動を行うことができると共に、大きな層厚の土砂除去が可能となる水底土砂除去装置および水底土砂除去工法を提供する。【解決手段】複数の土砂流入口と複数の水噴出口が長手方向に配設された土砂移送管と、該土砂移送管の概略中央に搭載した吸引ポンプにより前記土砂移送管内に水流を発生させると共に、前記水噴出口から水ジェットを噴出させて、前記土砂流入口から前記土砂移送管内に土砂を流入させ、かつ該土砂を前記水流に乗せて外部へ排出する水底土砂除去装置において、前記土砂移送管が、吸引ポンプの取り付け位置を中心に略Ｖ字形をなし、該Ｖ字形の突出側を下向きにしている。【選択図】図１
