<P>PROBLEM TO BE SOLVED: To recover/treat a large amount of excavation muck and muddy water generated in excavation construction. <P>SOLUTION: A recovery device 1 is a device for separating and recovering excavation muck and muddy water generated in excavation construction, and includes a container 13 for housing the excavation muck and the muddy water discharged accompanying excavation and a water tank 3 for storing the muddy water that overflows from the container. The container 13 has a discharge hole for discharging the excavation muck sunk on a bottom side. The water tank 3 is arranged at a lower part of the container 13 and receives the muddy water that overflows from the container. In the excavation construction, the discharged excavation muck and muddy water are housed in the container, the excavation muck suck at the lower part of the container is sucked to a vacuum car and transferred, and the muddy water that overflows from the container and is received by the water tank is sent to a turbidity reducing treatment facility. According to the present invention, when separating the excavation muck and the muddy water, since a mechanism of making only the muddy water overflow from the upper part of the container is adopted, the excavation muck and the muddy water are separated easily without using extra power for separation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
