Description
Technical field
The invention belongs to shield tunnel technical fields, and in particular to a kind of conveyer belt is slagged tap shield machine.
Background technology
When existing balancing earth-pressure shielding machine is taken out the dregs in soil cabin using screw conveyor, in order to keep dregs smooth
It by screw conveyor, and prevents from that dregs is gone out screw conveyor under the effect of soil cabin internal water pressure, under cutter head of shield machine cutting
When the dregs plasticity come is poor, it is necessary to inject certain sediment improvement agent and be improved to dregs；When the grain size of dregs is excessive,
When can not pass through screw conveyor, it has to open soil cabin and take out big grain size dregs by the way of artificial；For opposed helical
Sizable particle for conveyer gap will appear in screw conveyor by card, thus even screw rod be caused to be turned round
It is disconnected.
And slurry balance shield machine using mud cycle method by soil cabin dregs take out when, excessively large-sized dregs
It can not also face by mud circulating line and open the case where soil cabin takes out big grain size dregs by the way of artificial；Work as progress
When broken, for crushed-gravel to hydraulic fill pipeline slush pump serious wear, cost of equipment maintenance is high, when using mud circulation conveying dregs,
Earth's surface needs to build mud-settling pit, occupied ground, and mud causes serious pollution to the environment.It is more to prepare mud material therefor（Using swollen
Profit soil or other materials prepare mud）, electricity consumption is also big with water consumption.
Patent of invention " a kind of slagging mechanism and slurry balance shield machine of shield machine "（Application number：CN 105257305 A）
A kind of deslagging device proposing slurry balance shield machine is proposed, i.e., detaches the separation babinet of mud and gravel by design, it will
Gravel in slurry balance shield construction process mud is separated, and the slag discharge efficiency of slurry balance shield machine is improved.However, this
Patent still needs builds mud-settling pit in earth's surface, to face the problems such as place anxiety is with mud effect on environment.Meanwhile this
Patent is not used to balancing earth-pressure shielding machine.Dregs is transported to point by the device of this patent using double-pole spiral conveyer from Tu Cang
It carries out pressurize from babinet, and using double-pole spiral conveyer and prevents gushing, therefore, still suffering from excessive grain size can not pass through
It is difficult to when double-pole spiral conveyer and poor dregs plastic property using double-pole spiral conveyer conveying dregs and its pair
The problems such as anti-ability of gushing of pole screw conveyor is difficult to ensure.
Patent of invention " a kind of balancing earth-pressure shielding machine dregs pressurize pumping installations "（Application number：CN 104373130 A）,
Pressurize is carried out by the mixed mode of earth pressure balance and mud and water balance, similar " mud and water balance " is used on stratum of easily gushing
Shield-tunneling construction, but in " mud and water balance " shield-tunneling construction as use still acts as screw conveyor by dregs out of soil cabin
Output can not overcome the problems, such as that excessive grain size can not pass through screw conveyor, and big grain size dregs blocks screw conveyor
Problem, and theoretically earth's surface needs that mud-settling pit is arranged, and face the problems such as place anxiety is with mud effect on environment.
