Description
Technical field
The utility model relates to dam mud leakage water draining technology, belongs to Hydraulic and Hydro-Power Engineering field.
Background technology
It in order to discharge the percolating water in dam depended on two sides massif therewith, bottom dam, is provided with seepage drainage catchments
Well and draining pump house, in order to discharge percolating water in dam body in time, to ensure the operation safety of dam.Dam is from foundation dredging
To dam top pouring, often last for several years, even in order to ensure the safety of dam, after dam cast is bound, in dam
Still in the grouting carrying out necessity and closure in portion's each layer gallery, to guarantee that dam is even gone up a century in coming few decades and can be stablized
And safe operation.Seepage of dam drainage system then puts into operation already, containing high calcareous concrete during dam grouting
Mud is unavoidably mixed into the percolating water of dam, along each layer seepage drainage gallery, is finally pooled to the seepage collection bottom dam
Well, is discharged outside factory by drainage system.
Owing to seepage sump is typically located at the bottom of dam, and have inconvenient traffic, the concrete being deposited in sump
Cannot discharge smoothly, be substantially all and need to be discharged by draining pump and drainpipe, the water quality density owing to being mixed with concrete is long-range
In normal water quality density, draining pump power of motor is in overload operation, long-play, then the draining pump life-span significantly shortens, if
Standby fault rate is higher, and even some power station equipment faults cause cannot discharging percolating water in time, affect dam safety；This type of draining
Pump is many with longer lifting pipe, and dismounting is time-consumingly longer, and it is laborious to take a lot of work, and also brings very big puzzlement to operation maintenance personnel,
Currently also there is no preferable way to solve problems.
It is, thus, sought for safer reliable drainaging scheme and system operation maintenance mode, to reduce the event of equipment
Barrier rate, improves the reliability of drainage system, it is ensured that the operation safety of dam.
Content of the invention
Technical problem to be solved in the utility model is to provide the drainage system of a kind of dam mud leakage water, Neng Goubao
Card seepage of dam water is discharged smoothly.
The utility model solves the drainage system of technical problem the technical scheme is that dam mud leakage water, bag
Include primary, spare discharge pipe line, pump up water pipeline and water drain pump assembly, and described discharge pipe line includes being connected on diverse location
Primary discharge pipe line and standby discharge pipe line, described primary discharge pipe line and standby discharge pipe line are respectively equipped with switching valve,
Described primary discharge pipe line and described standby discharge pipe line can be unlocked simultaneously or be separately turned on, and the described pipeline that pumps up water connects
To described discharge pipe line, described pipeline and the described water drain pump assembly one_to_one corresponding of pumping up water, be provided with before the described pipeline that pumps up water for
The percolating water precipitation filtration system of cleaning seepage impurities in water.
While using technique scheme, the utility model can also use or combine employing further below
Technical scheme:
Described discharge pipe line is arranged on the above position, middle reaches of dam, is connected to be positioned at the bottom of dam under described lifting pipe road direction
The sump in portion, described percolating water precipitation filtration system is connected to described sump.
The described pipeline that pumps up water is many pipelines, and described many pipelines are respectively connecting to described discharge pipe line.
Described primary discharge pipe line is at least one, and described standby discharge pipe line is one or more.
The beneficial effects of the utility model are: drainage system of the present utility model is provided with primary and backup two class outlet rows
Water lines, and each be equipped with multiple tracks and pump up water pipeline, multiple tracks pumps up water pipeline and primary, spare discharge pipe line is respectively cooperating with, either example
Row maintenance still goes wrong when maintenance, guarantees have unobstructed pipeline to carry out draining, primary drainpipe all the time
Road and standby discharge pipe line can arrange different calibers, according to water quality and practical operation situation, simultaneously or switchover operation；Additionally,
It is provided with percolating water precipitation filtration system in drainage system of the present utility model, can the large granular impurity in percolating water be carried out pre-
Precipitation and filtration, play a protective role to pipeline and water pump group.
