Abstract
The utility model provides an improved shield machine drainage system, comprising a heavy-caliber sewage pump, a first drainage pipe, a secondary settling pond, a second drainage pipe, a settling pond sewage pump and a level controller, wherein the heavy-caliber sewage pump is suspended at the tail part of a shield machine and is connected with the secondary settling pond by the first drainage pipe, the secondary settling pond is connected with the settling pond sewage pump by the second drainage pipe, the level controller is arranged on the second settling pond, and the level controller is electrically connected with the settling pond sewage pump. As the improved shield machine drainage system adopts the heavy-caliber sewage pump, a great quantity of sewage containing sediments can be pumped away, so that the work of cleaning a shield tail before splicing duct pieces can be relieved; the secondary settling pond arranged in a trolley can be used for effectively settling the sewage from the shield tail, so that the possibility of plugging a rear drainage pipeline of the trolley is reduced; and the opening and the closing of the settling pond sewage pump can be controlled by the level controller on the secondary settling pond according to the level change of the setting pond, so that the working load of workers is greatly reduced.
Description
Technical field
The utility model relates to the sewage elimination technique field of shield machine, specifically is a kind of improved shield machine drainage.
Background technology
The phenomenon of slag all took place to gush, fall in shield machine to some extent in tunneling process at present, and the shield tail is assembled large amount of sewage and mud.The drainage of existing extra large Rake balancing earth-pressure shielding machine is provided with diaphragm pump, detergent line and a blowoff line, and its compositions is simple relatively, for still not being relatively good with the wastewater treatment efficiency of sandstone generally; But if gush, fall the situation of slag, since gush out silt become starchiness, also has finger stone once in a while, diaphragm pump and drainage pipeline thereof just are easy to stop up, the situation that gushing appears in particularly rich water sand-pebble layer is very many, adopt artificial pack cleaning if these problems have only, but progress is very slow, to influence construction speed greatly, thereby increase the engineering accident odds.
In view of this, how to provide a kind of improved shield machine drainage, reduce above-mentioned drawback and become the technical problem that industry needs to be resolved hurrily.
Summary of the invention
The utility model provides a kind of improved shield machine drainage, can in time get rid of shield tail sewage and part mud, reduces constructor's workload, improves efficiency of construction.
For solving the problems of the technologies described above, the utility model provides a kind of improved shield machine drainage, comprises heavy caliber foul water pump, first blow-off pipe, second-level settling pond, second blow-off pipe, sedimentation basin foul water pump and fluid level controller; The heavy caliber foul water pump is hung at the afterbody of shield machine, the heavy caliber foul water pump is connected with second-level settling pond by first blow-off pipe, second-level settling pond is connected with the sedimentation basin foul water pump by second blow-off pipe, fluid level controller is arranged on the second-level settling pond, and fluid level controller and sedimentation basin foul water pump electrically connect.
Further, second-level settling pond and sedimentation basin foul water pump are arranged on the chassis.
Further, the recirculated water interface is installed before heavy caliber foul water pump and the sedimentation basin foul water pump.
The utility model can move up and down in the shield tail, and can take the sewage that contains silt in a large number away by the use of heavy caliber foul water pump, has alleviated the work of clearing up the shield tail before the segment assembly; The second-level settling pond that is arranged in the chassis can effectively precipitate the sewage of coming from the shield tail, has reduced blowoff line possibility of jamming behind the chassis; The fluid level controller that is installed on the second-level settling pond can and stop according to the unlatching of the variation of sedimentation basin liquid level control sedimentation basin foul water pump, greatly reduce staff's workload, use the drainage after improving, greatly reduce water pump in the drainage, the blocked probability of pipeline, thereby improve efficiency of construction; Also effectively reduce simultaneously shield-tunneling construction security risk under complex geological condition.
Description of drawings
Fig. 1 is the structural representation of the improved shield machine drainage of the utility model.
Among the figure: 1-heavy caliber foul water pump, 2-first blow-off pipe, 3-second-level settling pond, 4-second blow-off pipe, 5-sedimentation basin foul water pump, 6-fluid level controller.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is clearly and completely described.
Figure 1 shows that the structural representation of the improved shield machine drainage of the utility model, described improved shield machine drainage comprises heavy caliber foul water pump 1, first blow-off pipe 2, second-level settling pond 3, second blow-off pipe 4, sedimentation basin foul water pump 5 and fluid level controller 6; Heavy caliber foul water pump 1 is hung at the afterbody of shield machine, in the vertical direction can move up and down, heavy caliber foul water pump 1 is connected with second-level settling pond 3 by first blow-off pipe 2, second-level settling pond 3 is connected with sedimentation basin foul water pump 5 by second blow-off pipe 4, fluid level controller 6 is arranged on the second-level settling pond 3, and fluid level controller 6 electrically connects with sedimentation basin foul water pump 5.
Wherein second-level settling pond 3 and sedimentation basin foul water pump 5 are arranged on the chassis, and be concrete, in the vacant position of chassis second-level settling pond 3 and sedimentation basin foul water pump 5 is installed.Fluid level controller 6 is used for the automatic operation draining according to the sewage quantity control sedimentation basin foul water pump 5 of second-level settling pond 3 precipitations, concrete, fluid level controller 6 is according to the operation of the variation control sedimentation basin foul water pump 5 of liquid level in the second-level settling pond 3, start sedimentation basin foul water pump 5 when making its liquid level be higher than certain position, close sedimentation basin foul water pump 5 when being lower than certain position to liquid level.Heavy caliber foul water pump 1 adopt have heavy caliber, power is the above foul water pump of 5.5kw, can twitch to contain an amount of sandstone, liquid that viscosity is bigger; The power of sedimentation basin foul water pump 5 can be 7.5kw, and the diameter 100-120mm of first blow-off pipe 2 can increase threeway and valve for standby on suitable ground.Before heavy caliber foul water pump 1 and sedimentation basin foul water pump 5, also the recirculated water interface can be installed, manage with the cleaning washing so that use the back.
During use, open heavy caliber foul water pump 1, because heavy caliber foul water pump 1 is hung at the afterbody of shield machine, but in the vertical direction can move up and down, can take the sewage that contains silt in a large number away, alleviate the work of clearing up the shield tail before the segment assembly, improved the continuity of shield-tunneling construction, reduced security risk; The sewage suction second-level settling pond 3 that will contain silt or stone by first blow-off pipe 2 precipitates, and has reduced blowoff line possibility of jamming behind the chassis; Fluid level controller 6 greatly reduces staff's workload according to the operation of the variation control sedimentation basin foul water pump 5 of liquid level in the second-level settling pond 3.
The above; it only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly belong to those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
