Muddy water circulating system for shield tunneling machine

PendingCN109209404APrevention of stagnationIncrease circulationTunnelsSlurryEngineering
The invention discloses a muddy water circulating system for a shield tunneling machine. The muddy water circulating system for the shield tunneling machine comprises a main slurry inlet pipeline anda main slurry discharging pipeline, wherein the tail end of the main slurry discharging pipeline is communicated with a muddy water cabin slurry discharging branch pipe and an air cushion cabin slurrydischarging branch pipe; both the muddy water cabin slurry discharging branch pipe and the air cushion cabin slurry discharging branch pipe are provided with valves; the elevation of the tail end ofthe muddy water cabin slurry discharging branch pipe is higher than that of the tail end of the air cushion cabin slurry discharging branch pipe. The muddy water cabin slurry discharging branch pipe and the air cushion cabin slurry discharging branch pipe can be opened separately. In a normal tunneling process, muddy water slurry is discharged through the air cushion cabin slurry discharging branch pipe. When discharge of muck in a muddy water cabin is hindered, a slurry door is closed, the valve on the air cushion cabin slurry discharging branch pipe is switched off while the valve on the muddy water cabin slurry discharging branch pipe is switched on, and the muddy water in the muddy water cabin is discharged directly through the muddy water cabin slurry discharging branch pipe, so thatthe slurry circulating strength in the muddy water cabin is enhanced, the residue carrying capability is enhanced, prevention of muck discharge hindering is facilitated greatly, the slurry content ofthe muddy water cabin is lowered, and the probability of mud lining on a cutterhead is lowered.
