Description
Technical field
The present invention relates to Shield Construction Technique field.
Background technology
At present, in shield method subway work engineering, during utilizing shield machine to tunnel, substantial amounts of sewage can be produced owing to rinsing chassis, section of jurisdiction etc., for ensureing that normal driving needs sewage to be discharged to outside hole.So being provided with foul water tank and sewage pump, and the soil pipe of installation diameter 100mm in tunnel at shield machine trailer backmost, by these equipment, sewage being discharged to hole, being delivered to the sedimentation tank on ground at hole by sewage pump.Because containing a large amount of mud, sandstone, cement etc. in sewage, so also needing to often spend human and material resources to go to clear up sedimentation tank.If these sewage to be simply passed through the outer row of precipitation, the serious waste of water resource will certainly be caused.It addition, subway work engineering is generally all located in urban district, if sewage disposal is improper, the blocking of municipal administration blow-off line also can be caused.
If shield machine tunneling process runs into the stratum of gravel matter cohesive soil, there will be belt and fall mud phenomenon, go to rinse chassis, section of jurisdiction with greater need for a large amount of water, in needing again to inject soil storehouse, a large amount of water are to improve soil property simultaneously, realizing sediment improvement, this further increases the consumption of water.If connecing soil pipe, need to put into substantial contribution, in addition it is also necessary to a large amount of manpowers have assisted.
Summary of the invention
The technical problem to be solved is to provide a kind of simple in construction, cost of manufacture is low, can improve water utilization rate, reduce operating cost, improve the shield-tunneling construction sewage reutilization device of work efficiency.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of shield-tunneling construction sewage reutilization device, including foul water tank, slush pump and effusion meter, is provided with valve between the outlet of described foul water tank and slush pump entrance point, and described slush pump export pipeline is provided with effusion meter, described slush pump export pipeline connection Tu Cang；The import and export of described slush pump are provided with amortisseur；On described slush pump export pipeline, being provided with branch road before effusion meter, the described branch road outlet slag car, the branch road before the described slag car is provided with choke valve.
Preferably, described valve is ball valve.
Preferably, described choke valve import connects air vent valve, and described air vent valve entrance end is equipped with stop valve.
Use and have the beneficial effects that produced by technique scheme: by slush pump, the sewage extraction in foul water tank is delivered to Tu Cang, in foul water tank outlet, ball valve is set to control flow, utilization is arranged on the amortisseur before and after slush pump to weaken the impulsive force of sewage, avoid pipeline is caused damage, display according to actual requirement and effusion meter regulates choke valve, control to inject the flow in soil storehouse by the choke valve on the branch road of slush pump export pipeline, choke valve regulates further through air vent valve, air vent valve utilizes the stop valve imported and exported to carry out auxiliary adjustment inlet and outlet pressure, the sewage surplus not utilized is delivered to the slag car by throttle valve control bypass flow again and transports outward.The present invention has simple in construction, cost of manufacture is low, can improve water utilization rate, reduce operating cost, improve the advantage of work efficiency, decreases equipment funds and puts into and human cost, has the strongest practicality.

Detailed description of the invention
The present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings.
nullA kind of shield-tunneling construction sewage reutilization device as shown in Figure 1，Including foul water tank 1、Slush pump 4 and effusion meter 5，Described foul water tank 1 exports and is provided with valve 2 between slush pump 4 entrance point，Valve 2 can use ball valve，Described slush pump 4 export pipeline is provided with effusion meter 5，Described slush pump 4 export pipeline connection soil storehouse 6，Import and export at slush pump 4 are provided with amortisseur 3，Avoid that Sewage shock power is excessive causes damage to pipeline，On slush pump 4 export pipeline、And between port of export amortisseur 3 and effusion meter 5, set a branch road，The described branch road outlet slag car 8，Branch road before the described slag car 8 is provided with choke valve 7，The sewage quantity injecting soil storehouse 6 is regulated by choke valve 7，Air vent valve 9 is connected in choke valve 7 import，The admission pressure of choke valve 7 is controlled by air vent valve 9，Thus reach the effect of choke valve 7 controlling brancher flow，Described air vent valve 9 entrance end is equipped with stop valve 10，Can utilize this stop valve 10 that air vent valve 9 carries out maintenance to change.
By slush pump 4, the sewage extraction in foul water tank 1 is delivered to soil storehouse 6, in foul water tank 1 outlet, valve 2 is set to control flow, also can be by closing ball valve, conveniently each equipment after foul water tank 1 is safeguarded, utilization is arranged on the amortisseur 3 before and after slush pump 4 to weaken the impulsive force of sewage, avoid pipeline is caused damage, display according to actual requirement and effusion meter 5 regulates choke valve 7, control to inject the flow in soil storehouse 6 by the choke valve 7 on the branch road of slush pump 4 export pipeline, choke valve 7 regulates further through air vent valve 9, the sewage surplus not utilized is delivered to the slag car 8 by choke valve 7 controlling brancher flow again and transports outward.For the structure of existing shield machine, foul water tank and comprise effusion meter and be each provided on No. five chassis at interior each parts, by the pipeline after effusion meter successively along No. four chassis, No. three chassis, No. two chassis, chassis, cross structure, shield body, enter back in soil storehouse.The water yield of abundance is to carry out sediment improvement to utilize this device can ensure that, as bentonite need to be made, available foul water tank only needs fermentation as fermenting case, recycle in this device squeezes into soil storehouse and carry out sediment improvement, can also dispersed with stirring agent in foul water tank, recycle this device inject soil storehouse in, preferably improve dregs, and effectively prevent Tu Cang and cutterhead mud lining, it is to avoid cause irremediable loss.
In sum, the present invention has simple in construction, cost of manufacture is low, can improve the advantage of water utilization rate, decreases equipment funds and puts into and human cost, has the strongest practicality.If shield-tunneling construction total kilometrage is 4.3 kilometers, connects soil pipe and about need 280,000 yuan, utilize the present invention the most only to need 6 meters of long soil pipes, it is only necessary to about 400 yuan, while saving substantial contribution, to also save labour cost.
