The utility model using when mixed by the cutterhead rotary cutting soil body and the thick mud from slurry pipeline,
Constantly stirred by the cutterhead stirring rod of cutterhead and form excavation area mud film, while cutterhead surrounding cutterhead side is provided with injected hole and existed
The section of backbreaking of cutterhead fills thick mud and forms area's mud film of backbreaking, and area's mud film is backbreak gradually to pusher when continuous propulsion moves ahead
Shifting is converted into the outer mud film of cylinder tube wall, and behind stable and balance excavation area, the propulsion of push-bench makes excavation area spoil hopper pressure
Increase to can spoil disposal pressure value, by opening the conveyer mud discharging mouth installed in Shaftless screw conveyor tail seal, and open
Dynamic Shaftless screw conveyor makes its blade rotate to form spiral thrust, mud mudstone is expelled to device for separating mud and water, passes through mud
The filtering and separation of water separation device, mud and small crushed stone fall into mud ditch, and bulk crushed gravel rock slide enters travelling bogie, lead to
Cross travelling bogie and transport bulk crushed gravel sillar, and pumping is arranged by mud and discharges mud and small crushed stone in mud ditch, when
Excavation area spoil hopper pressure reduced with spoil disposal to can spoil disposal lower limit when, close conveyer mud discharging mouth simultaneously stop shaftless screw conveying
Machine, the closing of mud discharging mouth is caused, while during spoil disposal, can by adjusting the helical blade rotating speed of Shaftless screw conveyor
The uninterrupted and fltting speed for realizing spoil disposal match, and realize in the case where ensureing excavation area spoil hopper pressure balance, continuous work
Make.The utility model is tackled the soft soil horizon containing cobble and existed by being configured with the dense mud formula push-bench of Shaftless screw conveyor
Cutterhead equipped with tunneling boring cataclasitlc structure, after progress First Extrusion is broken, the size crushed stone that cobble and sillar are formed passes through knife
Disk filters mouth, forces to crush without secondary, by under excavation face pressure difference and Shaftless screw conveyor helical blade thrust, you can directly
Discharged by Shaftless screw conveyor, so as to simplify cataclasitlc structure, reduce complete machine power, improve dynamical system stability, reduce
Equipment cost；Simultaneously compared with common slurry-water balance type push-bench, the possibility of spoil disposal line clogging, mudstone separator are eliminated
Separable mud and cobble, high concentration muddy water is discharged by spoil disposal pipeline, then bulk cobble is discharged by travelling bogie, improve length
Apart from the efficiency of construction of jacking.
