Description
Technical field
The present invention relates to Shield Construction Technique field.
Background technology
At present, in shield method subway work engineering, utilize in the process that shield machine tunnels, can produce a large amount of sewage owing to rinsing chassis, section of jurisdiction etc., for ensureing that normal driving need to be discharged to sewage outside hole.So shield machine backmost trailer be provided with foul water tank and foul water pump, and the soil pipe of diameter 100mm is installed in tunnel, by these equipment, sewage is discharged to hole, deliver to the sedimentation basin on ground by foul water pump at hole.Because contain a large amount of mud, sandstone, cement etc. in sewage, remove to clear up sedimentation basin so also need often to spend human and material resources.If these sewage, simply through just whole outer rows of precipitation, will certainly be caused to the serious waste of water resource.In addition, subway work engineering is generally all located in urban district, if sewerage treatment is improper, also can cause the obstruction of municipal blow-off line.
If run into the stratum of gravel matter cohesive soil in shield machine tunneling process, there will be belt to fall mud phenomenon, more need large water gaging to go to rinse chassis, section of jurisdiction, need again to inject large water gaging in native storehouse and improve soil property simultaneously, realize sediment improvement, this has further strengthened again the consumption of water.If connect soil pipe, need to drop into substantial contribution, also need a large amount of manpowers to assist.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of simple in structure, cost of manufacture is low, can improve water utilization rate, the shield-tunneling construction sewage reutilization device that reduces running cost, increase work efficiency.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of shield-tunneling construction sewage reutilization device, comprises foul water tank, slush pump and flow meter, between described foul water tank outlet and slush pump entrance point, is provided with valve, and described slush pump export pipeline is provided with flow meter, and described slush pump export pipeline is communicated with Tu Cang.
Preferably, the import and export of described slush pump are provided with damper.
Preferably, described valve is ball valve.
Preferably, on described slush pump export pipeline, be provided with branch road before flow meter, described way outlet is communicated with the slag car, and the branch road before the described slag car is provided with choke valve.
Preferably, described choke valve import connects air vent valve, and described air vent valve entrance end is equipped with stop valve.
The beneficial effect that adopts technique scheme to produce is: by slush pump, the sewage in foul water tank is extracted out and is delivered to Tu Cang, in foul water tank outlet, ball valve is set and controls flow, utilization is arranged on damper before and after slush pump and weakens the impact force of sewage, avoid pipeline to cause damage, regulate choke valve according to the demonstration of actual requirement and flow meter, control the flow injecting in native storehouse by the choke valve on the branch road of slush pump export pipeline, choke valve regulates by air vent valve again, the stop valve that air vent valve utilization is imported and exported carrys out auxiliary adjustment inlet and outlet pressure, the sewage surplus of not utilized is delivered to slag car outward transport by throttle valve control branch road flow again.That the present invention has advantages of is simple in structure, cost of manufacture is low, can improve water utilization rate, reduce running cost, increase work efficiency, and has reduced equipment funds and has dropped into and human cost, has very strong practicality.
Brief description of the drawings
Fig. 1 is the structural principle schematic diagram of one embodiment of the present of invention;
In figure: 1-foul water tank, 2-valve, 3-damper, 4-slush pump, 5-flow meter, 6-Tu Cang, 7-choke valve, the 8-slag car, 9-air vent valve, 10-stop valve.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
A kind of shield-tunneling construction sewage reutilization device as shown in Figure 1, comprise foul water tank 1, slush pump 4 and flow meter 5, between described foul water tank 1 outlet and slush pump 4 entrance points, be provided with valve 2, valve 2 can adopt ball valve, described slush pump 4 export pipelines are provided with flow meter 5, described slush pump 4 export pipelines are communicated with native storehouse 6, be provided with damper 3 in the import and export of slush pump 4, avoid that Sewage shock power is excessive causes damage to pipeline, on slush pump 4 export pipelines, and establish a branch road between port of export damper 3 and flow meter 5, described way outlet is communicated with the slag car 8, branch road before the described slag car 8 is provided with choke valve 7, regulate the sewage quantity that injects native storehouse 6 by choke valve 7, connect air vent valve 9 in choke valve 7 imports, control the admission pressure of choke valve 7 by air vent valve 9, thereby reach choke valve 7 and control the effect of branch road flow, described air vent valve 9 entrance ends are equipped with stop valve 10, can utilize this stop valve 10 to carry out maintain and replace to air vent valve 9.
By slush pump 4, the sewage in foul water tank 1 is extracted out and is delivered to native storehouse 6, in foul water tank 1 outlet, valve 2 is set and controls flow, also can be by closing ball valve, conveniently the each equipment after foul water tank 1 is safeguarded, the damper 3 that utilization is arranged on slush pump 4 front and back weakens the impact force of sewage, avoid pipeline to cause damage, regulate choke valve 7 according to the demonstration of actual requirement and flow meter 5, control the flow injecting in native storehouse 6 by the choke valve 7 on the branch road of slush pump 4 export pipelines, choke valve 7 regulates by air vent valve 9 again, the sewage surplus of not utilized is controlled branch road flow by choke valve 7 again and is delivered to the slag car 8 and transports outward.For the structure of existing shield machine, foul water tank and comprise flow meter and be all located on No. five chassis at interior each parts, pipeline after flow meter, successively along No. four chassis, No. three chassis, No. two chassis, chassis, connecting bridge, shield body, then is entered in native storehouse.Utilize this device can ensure that the sufficient water yield carries out sediment improvement, as need are made swell soil, can utilize foul water tank only to need fermentation as fermenting case, recycling this device squeezes into and in native storehouse, carries out sediment improvement, also can dispersed with stirring agent in foul water tank, recycle this device and inject in native storehouse, improve better dregs, and effectively prevent Tu Cang and cutterhead mud lining, avoid causing irremediable loss.
In sum, that the present invention has advantages of is simple in structure, cost of manufacture is low, can improve water utilization rate, has reduced equipment funds and has dropped into and human cost, has very strong practicality.If shield-tunneling construction total kilometrage is 4.3 kilometers, connect soil pipe and approximately need 280,000 yuan, utilize the present invention only to need 6 meters of long soil pipes, only need 400 yuan of left and right, when having saved substantial contribution, also save labour cost.
