A platform for research: civil engineering, architecture and urbanism
To provide a dredging structure capable of further suppressing diffusion of mud into water and improving recovery rate (a ratio of mud to a whole recovery amount including water).SOLUTION: A dredging structure 1 comprises: a body case 2 formed in a box-shape including an opening 11 opening downwardly and having a suction port 12 opening inside and above the opening; a plate-shaped digging-in blade 3 extending to a front side in a travelling direction as moving downwardly from a rear side opening edge portion 22 positioned at a rear side in the travelling direction in the opening; a pair of side wall portions 4 extending from both ends in a width direction of the digging-in blade at least to the opening; and a front side extending portion 5 extending from a front side opening edge portion 21 positioned at the front side in the travelling direction to the front side in the travelling direction in the opening.SELECTED DRAWING: Figure 1
【課題】浚渫用構造体において、泥土の水中への拡散をさらに抑制でき、かつ、泥土の回収率(水を含む回収量全体に対する泥土の割合)を向上できるようにする。【解決手段】下方に開口する開口部11を有する箱状に形成されると共に、前記開口部よりも上側において内部に開口する吸込口12を有する本体ケース2と、前記開口部のうち進行方向後側に位置する後側開口縁部22から、前記下方に向かうにしたがって進行方向前側に延びる板状の掘込刃3と、前記掘込刃の幅方向両端から少なくとも前記開口部まで延びる一対の側壁部4と、前記開口部のうち進行方向前側に位置する前側開口縁部21から、進行方向前側に延びる前側延出部5と、を備える浚渫用構造体1を提供する。【選択図】図1
