Zusammenfassung:PURPOSE:To continuously excavate sediment, force-feed it in the slurry state, continuously dehydrate the slurry sediment, and separate it into solidified soil as surplus soil. CONSTITUTION:Slurry is fed to the working face via a mud feeder, sediment is excavated with an excavator, and the sediment is force-fed to a static mixer 12 by a soil discharge device together with slurry through a soil discharge pipe 7. The slurry sediment force-fed to the static mixer 12 is kneaded as a slurry processing material, then it is fed to a screw press 13 and dehydrated, and it is separated into solidified soil discardable as general surplus soil.
