Document Type and Number:
WIPO Patent Application WO/2018/142591
Kind Code:
A1
Abstract:
[Problem] Conventionally, there exists a device by which high-pressure water is sprayed into the sediment at the bottom of a reservoir, the sediment is excavated and slurried, the slurried sediment is delivered onto land with a suction pipe, and the same is subjected to separation. Using a wall-equipped cover, dissipation of the slurried sediment is prevented, or in the wall-equipped cover, the movement of high-pressure water is secured. However, there are problems, including: such a device is large due to having a configuration in which cable is laid, a high-pressure water pipe and a suction pipe are supported, and each pipe is moved; and device maintenance requires time and effort. [Solution] The purpose of the present invention is to: solve a problem such that, conventionally, if suction was carried out with a suction pump, sludge and sediment in a certain range of the suction pump is suctioned, and such suctioned area becomes a mortar shape, and thereafter, only water above such area is suctioned, and sludge and sediment are no longer suctioned; solve the problem of turbidity occurring with sludge and sediment outside a suctioning region by enclosing mixed sludge and sediment inside such suctioning region; and efficiently separate and process an accumulation of the mixed sludge and sediment.
