In urban water supply engineering, for improving water supply flow and water supply fraction, the mode that often adopts many reservoirs to supply water, service reservoir can adopt series winding or mode in parallel.
Series winding water distribution system is by being communicated with tunnel or pipeline, and after each service reservoir is connected, by the unification of end reservoir, to water factory's water distribution, this system can effectively gather the discharge of coming of each service reservoir, improves water distribution quantity.Yet, once certain Reservoir Water Quality generation problem of system or certain section of tunnel pipeline need maintenance, will affecting the water distribution of whole system, water supply fraction is not high.
And connect each service reservoir of water distribution system and all by independently tunnel or pipeline, to water factory's water distribution, both can effectively utilize the discharge of coming of each service reservoir, can improve water supply fraction again; Yet service reservoir all adopts independently water supply network also to mean increasing considerably of engineering quantity and investment.
Consider economy and reasonability, the mode that also has urban water supply engineering to adopt " service reservoir associating balancing reservoir " to supply water.The balancing reservoir storage capacity relatively independent with service reservoir is generally less, apart from little, pipe network investment is little with water factory, and independent operating only can meet the water distribution demand of city short-term, only, at service reservoir underfed, need to use in the situations such as interim increasing distributed water flow or service reservoir pipe network need to overhaul.Due to balancing reservoir collective area and storage capacity little, dry season, discharge was little, often restricted the performance of balancing reservoir regulating power, in addition, after balancing reservoir supplies water, for reservoir capacity, can only lean on the runoff in self collective area to recover gradually, required recovery time is longer.

(2) shunting operational mode, service reservoir is simultaneously to balancing reservoir and Water Works: open intake gate, be communicated with lock and go out sluice, control water inlet pipe flow and be greater than outlet pipe flow, water inlet pipe enters distribution well from the discharge of coming of service reservoir, part flow enters water factory from outlet pipe and meets water requirements, and a part of flow supplements the balancing reservoir water yield from entering balancing reservoir communicating pipe.
(3) normal operation mode, service reservoir is independent of Water Works: open intake gate and go out sluice, close connection lock, control the flow of water inlet pipe and the flow of outlet pipe basically identical or be slightly larger than the flow of outlet pipe, water inlet pipe enters distribution well from the discharge of coming of service reservoir, from outlet pipe, enter water factory, water level substantially constant or rising in distribution well, the water yield more than needed enters balancing reservoir from overfall on a small quantity.
(4) inspection travel pattern, balancing reservoir is independent of Water Works: close intake gate, open and be communicated with lock and go out sluice, the moisturizing of balancing reservoir enters water factory from outlet pipe after entering distribution well, and this operational mode is generally used when distribution well upstream water-carriage system overhauls.
(5) water quality of fast quick-recovery balancing reservoir, in balancing reservoir, water quality occurs abnormal, close and be communicated with lock and go out sluice, the temporary transient water supply of interrupting to water factory, the discharge of coming of water inlet pipe self-water-supplying reservoir enters after distribution well from overfall to balancing reservoir overflow, in distribution well after quality recovery, open out sluice, when continuing to balancing reservoir overflow moisturizing by overfall, through outlet pipe Water Works downstream, after the water quality of balancing reservoir is recovered completely, open and be communicated with lock, by communicating pipe shunting moisturizing to balancing reservoir.
The beneficial effects of the utility model are:
(1) compare with the water distribution system of service reservoir, balancing reservoir series connection, the flow-compensated formula water distribution system in well storehouse is only many distribution well, communicating pipe and be communicated with lock, investment is more or less the same, and has but realized the function that service reservoir and balancing reservoir all can independent operatings, has improved water supply fraction.
(2) compare with the water distribution system of service reservoir, balancing reservoir parallel connection, the utility model is reduced investment not only, can realize equally that service reservoir supplies water separately, balancing reservoir water supply separately, service reservoir and balancing reservoir combine to 3 kinds of water distribution modes of Water Works, more than service reservoir simultaneously to the water distribution mode of balancing reservoir and Water Works, service reservoir flow can make it keep the more water yield by compensating reservoir, further improves the water supply fraction of whole water distribution system.
(3) more flexible on optimization, when connection lock cuts out, the variation of downstream water supply traffic demand can be adjusted voluntarily by distribution well SEA LEVEL VARIATION, in distribution well water distribution process, brings into play the effect of surge shaft simultaneously.When distribution well flow is had more than needed, even without operable communication lock, the water yield more than needed enters balancing reservoir by distribution well overfall, and former water can not wasted.
(4) just in case abnormal conditions appear in balancing reservoir water quality, can close connection lock, on the one hand, water-carriage system isolation balancing reservoir normally moves, safeguards system water supply security; On the other hand, control distribution well water inlet pipe flow and be greater than outlet pipe flow, lifting distribution well water level, improves balancing reservoir water quality from the overfall of distribution well to balancing reservoir shunting, fast quick-recovery balancing reservoir function.
