Document Type and Number:
Japanese Patent JP7082344
Kind Code:
B2
Abstract:
To provide a slurry treatment facility that can properly treat drainage slurry foaming even when excavating improved ground containing concrete structures and cement, etc., constructed underground, using the slurry shield method and slurry propulsion method.SOLUTION: A slurry treatment facility 10 is used for the slurry shield method or slurry propulsion method, and has an adjustment tank 20 for storing the drilling slurry, a slurry pipe 40 for supplying the drilling slurry from the adjustment tank to a drilling machine 60, a drainage slurry pipe 41 for recovering from the drilling machine the slurry with excavated soil generated by the drilling machine, and a sediment separator 23 for separating sediment from drainage slurry.
