Configure application method.
Background technology
The Construction Principle of slurry shield machine is the palm in front of cutter head of shield machine storehouse by suitable proportion and the mud of viscosity
Sub- face forms mud film, the lateral pressure on stratum and underground water is balanced by the mud pressure full of cutterhead storehouse, so as to reach area
Face is stable, and the dregs that knife cutting is got off by mud carries out ground, reaches solid after sludge-water separating system is handled
Dregs and mud separation, the mud isolated recycle after sedimentation basin precipitates, then after adjustment by mud balance and viscosity
Recycling.
But when the geological condition that slurry shield machine passes through is using the fine grained such as clay, silt, silty clay stratum to be main, mud
Water quality structure is frequently run onto the solid dregs amount that sludge-water separating system is isolated and is far less than the dregs amount excavated out, substantial amounts of thin
Grain material enters mud, causes mud balance and viscosity constantly to rise.Because such a thin particulate matter is mostly by less than 20 μm
Clay particle thing forms, and is even precipitated through long-time, and this fine particle is constantly in suspended state in mud, can not be thorough
Separate.When mud balance and viscosity reach a threshold value, for example proportion reaches 1.3g/cm3, after viscosity reaches 30s, mud
Slurry will be unable to normal use.Problems be present in the shortcomings that traditional slurry shield machine mud pit application method：

The speed of the mud of new mixing can not meet the needs of two slurry shield normal constructions, and new mud puffing time of mixing is insufficient,
Quality of mud fluid can not be ensured.
2nd, every slurry shield is only configured with a set of sedimentation basin, an adjustment pond and an overfall pond, with mud balance
With the continuous rise of viscosity, the drivage efficiency of slurry shield can be gradually reduced, when the proportion and viscosity of mud rise to and can not expired
When sufficient shield-tunneling construction needs, only stop shield driving, shutdown process discarded slurry, so can not only influence the construction period, also
The huge work holdup can be caused to lose.
3rd, adjust and a fixed mud stirring device is only installed in pond, the shortcomings that the mud stirring device of this fixation
Have：One is the mud in each orientation that adjust pond can not be stirred in place, stir less than local mud can gradually sink
Form sediment, can not only reduce the volume in adjustment pond, can also influence to adjust the quality of pond mud；The second is mixing arm is longer, when mud ratio
Weight it is larger when often damage mixing arm, now need stop work after by adjust pond in mud whole pump drainage it is clean after again to stirring
Arm is repaired, and so not only delays the duration, also results in mud contamination environment, wastes mud materials and water resource.
