Abstract
The invention relates to a vacuum sludge discharge shield system. The vacuum sludge discharge shield system comprises a shield machine placed in a tunnel and used for propelling, pipe joints placed in the tunnel, a sludge generating and treating system, a vacuum pump and a sludge storage tank arranged outside the tunnel, and the like. High concentration sludge is utilized to fill in and pressurize an excavation surface and an overexcavation part; excavated muck and pebble are mixed to form condense sludge with collapsbillity approximately at 20; when the inner pressure and the outer pressure of a cutter head cabin reach critical balance, a lip vacuum mud valve is utilized to drain and discharge the sludge to a sludge storage tank in the machine. The workload efficiency is high; the safety is good; bad influences on the surface such as surface bulging, sinking and collapse cannot happen easily; the construction accuracy is excellently improved; the cost is reduced.

At present, in China's city tunnel, pipeline network construction, the casting mode of shield machine, push-bench be take two kinds of modes of screw machine and muddy water circulation as main, the screw machine that wherein earth pressure balance is conventional and conveyer belt pattern, and casting inefficiency, transportation is complicated.It is high that the muddy water that slurry balance shield machine is conventional is processed piece-rate system cost of equipment, and ambient influnence is large and occupied ground is many, the abnormal height of holistic cost.
Summary of the invention
The technical problem to be solved in the present invention is: propose that a kind of low cost, construction quality are stable, high, the sanitary vacuum spoil disposal of casting efficiency shield construction system.
The technical solution adopted in the present invention is: a kind of vacuum spoil disposal shield construction system, comprises and being placed in tunnel for the shield machine advancing, the tube coupling of having placed in tunnel and the mud generation and treatment system, vacuum pump and the storage mud tank that are arranged on outside, tunnel; The head of described shield machine has cutterhead, and cutterhead inner side arranges cutterhead cabin; The outside of cutterhead has spray mud mouth; Described mud occur and treatment system by send mud pipeline to be connected with cutterhead and by mud, occur and treatment system in the dense mud modulated deliver to cutterhead end face and spray by spraying mud mouth;
The rear side in described cutterhead cabin is provided with lip formula vacuum mud valve, and the afterbody of lip formula vacuum mud valve connects storage mud groove; Described lip formula vacuum mud valve drains into by vacuum attraction the dense mud that is mixed with native slag stone in cutterhead cabin in storage mud groove; Described storage mud groove is connected with the storage mud tank of outside, tunnel by spoil disposal pipeline, and the negative pressure that described storage mud tank produces by the vacuum pump being attached thereto attracts the dense mud in storage mud groove to drain in storage mud tank.
Further, for shield machine be can be good in suspension and tunnel, the slump of dense mud of the present invention is 18～22; The proportion of the dense mud of modulating in described mud generation and treatment system is 1.3～1.5.
Further say, in storage mud groove of the present invention, be provided with mudstone isolating construction.Rock can enter in pipe after fragmentation, by pipeline, carries rubble, reduces workload, raises the efficiency, and increases safety.
Sludge discharge way of the present invention is vacuum transport mode.Can grow distance and carry, and can select directly to drain in ground storage mud groove or mud car.In order to improve construction precision and safety, lip formula vacuum mud valve of the present invention comprises outside steel valve body cover and is arranged on the lip formula rubber valve body in valve cover; Described lip formula rubber valve body is for having deformation region; The two ends of described lip formula rubber valve body are fixed on valve cover; Between valve cover inwall and lip formula rubber valve body, leave the space that is filled with gas.
The invention has the beneficial effects as follows: by high concentration muddy water, excavation surface and the portion's of backbreaking pressurization are full of, after the dregs of excavation, rubble mix, form the dense thickened drilling fluid of slump 20 left and right; When the external and internal pressure critical balance of cutterhead cabin, by lip formula vacuum mud valve, attract to drain in machine to store up mud groove, not only workload efficiency is high, safe; And be difficult for there is surface uplift, the impact bad on earth's surface such as sink to subsiding, well improved construction precision, cost reduction.

The specific embodiment
The present invention is further detailed explanation with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
A kind of vacuum spoil disposal shield construction system as shown in Figure 1, comprises and being placed in tunnel for the shield machine advancing, the tube coupling of having placed in tunnel and the mud generation and treatment system, vacuum pump and the storage mud tank that are arranged on outside, tunnel; The head of shield machine has cutterhead, and cutterhead inner side arranges cutterhead cabin; The outside of cutterhead has spray mud mouth; Mud occur and treatment system by send mud pipeline to be connected with cutterhead and by mud, occur and treatment system in the dense mud modulated deliver to cutterhead end face and spray by spraying mud mouth;
The rear side in cutterhead cabin is provided with lip formula vacuum mud valve, and the afterbody of lip formula vacuum mud valve connects storage mud groove; Lip formula vacuum mud valve drains into by vacuum attraction the dense mud that is mixed with native slag stone in cutterhead cabin in storage mud groove; Lip formula vacuum mud valve comprises outside steel valve body cover and is arranged on the lip formula rubber valve body in valve cover; Lip formula rubber valve body is for having deformation region; The two ends of lip formula rubber valve body are fixed on valve cover; Between valve cover inwall and lip formula rubber valve body, leave the space that is filled with gas.
As shown 2, the air of the about 0.25MPa of charged pressure between valve cover and rubber valve body, rubber valve body is when B position, and mud valve is closed, and keeps soil pressure in native storehouse; After compressed air between valve cover and rubber valve body discharges, rubber valve body is when B ' position, and mud valve is opened, and valve body front end soil storehouse internal pressure is higher than rear portion storage mud groove internal pressure, and dregs pressurized, drains into storage mud groove in machine.
Storage mud groove is connected with the storage mud tank of outside, tunnel by spoil disposal pipeline, and the negative pressure that described storage mud tank produces by the vacuum pump being attached thereto attracts the dense mud in storage mud groove to drain in storage mud tank.
