Detailed Description
Reference will now be made in detail to the present preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.
In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.
Referring to fig. 1 and 2, the tunnel drainage system according to the embodiment of the present invention includes a sedimentation tank 10, a first drainage structure 20, a second drainage structure 30, a diversion structure 40, and a control system (not shown). A water level gauge 11 and a floating box 12 are arranged in the sedimentation tank 10, the first drainage structure 20 comprises a first drainage pipe 21, a first delivery pump 22 and a first on-off valve 23, the inlet end of the first drainage pipe 21 is arranged on the floating box 12, the first delivery pump 22 and the first on-off valve 23 are both arranged on the first drainage pipe 21, and the first on-off valve 23 is positioned at the front side of the first delivery pump 22. The second drain structure 30 includes a second drain pipe 31 and a second transfer pump 32, and the second transfer pump 32 is disposed on the second drain pipe 31. The flow dividing structure 40 includes a flow dividing pipe 41, a third delivery pump 42 and a one-way valve 43, an inlet end of the flow dividing pipe 41 is connected to the first liquid discharge pipe 21 at the rear side of the first delivery pump 22, an outlet end of the flow dividing pipe 41 is connected to the second liquid discharge pipe 31 at the front side of the second delivery pump 32, and the third delivery pump 42 and the one-way valve 43 are disposed on the flow dividing pipe 41. The control system is electrically connected to the water level gauge 11, the first delivery pump 22, the second delivery pump 32, and the third delivery pump 42. The control system receives the signal output by the water level gauge 11 and can control the start and stop of the first conveying pump 22, the second conveying pump 32 and the third conveying pump 42.
The mountain seepage water can be discharged to the sedimentation tank 10, or conveyed into the sedimentation tank 10 through a water pump, and impurities with large specific gravity can be deposited at the bottom of the sedimentation tank 10. When the mountain body seepage water needs to be discharged, the first on-off valve 23 can be opened, and the first delivery pump 22 is started through the control system to discharge the water in the sedimentation tank 10. The buoyancy of the water can make the buoyancy tank 12 and the inlet end of the first drain pipe 21 leave the bottom of the settling tank 10, and prevent impurities from entering the first drain pipe 21. When it is desired to discharge the muddy water, the second transfer pump 32 can be controlled by the control system to be activated to discharge the muddy water. Through above-mentioned structure, can separate the drainage with mud water and massif infiltration, can reduce the water yield that needs to handle, reduce treatment cost, also be convenient for carry out recovery processing with massif infiltration simultaneously.
After a period of use, impurities will accumulate in the second liquid discharge pipe 31, at which time the first on-off valve 23 can be closed, and the control system controls the third delivery pump 42 to be started, so as to feed water in the sedimentation basin 10 into the second liquid discharge pipe 31 and flush the second liquid discharge pipe 31. In the tunnel construction process, the flow rate of the mountain seepage water may increase suddenly, and the mountain seepage water needs to be discharged quickly, and at this time, the first delivery pump 22 and the third delivery pump 42 may be started simultaneously, so that the water in the sedimentation tank 10 is discharged simultaneously through the first drainage pipe 21 and the second drainage pipe 31.
The water level gauge 11 can detect the water level in the sedimentation tank 10 and feed back the value of the water level to the control system. The increment of the water level height in unit time is the rising speed of the water level height. If the rising speed of the water level exceeds the first set value, it can be judged that the mountain seepage quantity suddenly increases, and the control system can control the first delivery pump 22 and the third delivery pump 42 to be started simultaneously. In addition, when the rising speed of the water level does not exceed the first set value, if the value of the water level does not exceed the second set value, the first transfer pump 22 may not be activated; when the value of the water level height exceeds the second set value, the first delivery pump 22 starts draining. The first transfer pump 22 can be operated intermittently, so as to reduce energy consumption, prevent the first transfer pump 22 from idle operation, and prevent the inlet end of the first drainage pipe 21 from falling to the bottom of the sedimentation tank 10 to suck impurities due to the low water level.
The shunt tube 41 is inclined to the first drain tube 21 to facilitate water flow into the shunt tube 41.
Referring to fig. 2, the buoyancy tank 12 includes a netpen 121, a hook 122 and a buoyancy block 123, the hook 122 is disposed on the netpen 121, the hook 122 is hung on the buoyancy block 123, so that the netpen 121 is hung on the buoyancy block 123, and the inlet end of the first drainage pipe 21 extends into the netpen 121. The net cage 121 can prevent suspended impurities in water from being sucked by the first drain pipe 21. The netpen 121 may be removed when it is desired to clean the netpen 121 or when rapid drainage is desired. The buoyancy block 123 may be a wood block, a foam block, or a hollow box structure.
The stirring device 13 is arranged in the sedimentation tank 10, a third liquid discharge pipe 51 is arranged between the second liquid discharge structure 30 and the sedimentation tank 10, a second on-off valve 33 is arranged on the second liquid discharge pipe 31, the second on-off valve 33 is positioned at the rear side of the second conveying pump 32, the inlet end of the third liquid discharge pipe 51 is communicated with the bottom of the sedimentation tank 10, and the outlet end of the third liquid discharge pipe 51 is communicated with the second liquid discharge pipe 31 between the second conveying pump 32 and the second on-off valve 33. The impurities at the bottom of the sedimentation tank 10 can be stirred and lifted by the stirring device 13, and the water at the bottom of the sedimentation tank 10 can be discharged through the second liquid discharge pipe 31 by the third liquid discharge pipe 51 and the second delivery pump 32, so that the impurities in the sedimentation tank 10 can be removed.
Specifically, the stirring device 13 includes a fourth delivery pump 131 and a fourth liquid discharge pipe 132, the fourth delivery pump 131 is disposed on the fourth liquid discharge pipe 132, an inlet end of the fourth liquid discharge pipe 132 is disposed on the floating box 12, and an outlet end of the fourth liquid discharge pipe 132 is located at the bottom of the sedimentation tank 10.
