Designed displacement takes second place, and the designed displacement of three-level main pipe net is minimum, the level-one main pipe net, second level main pipe net, three-level main pipe
Net passes through gate respectively and is connected to each pipe network.
Further, the gathering ground and level-one main pipe net, second level main pipe net, be equipped with flow restriction between three-level main pipe net
Gate.
A kind of drainage pipeline networks dispatching method of Urban Flood Waterlogging, comprising:
Step 1, the drainage pipeline networks for being laid with a kind of Urban Flood Waterlogging；
Step 2 is based on weather forecast, and the spatial and temporal distributions of rainfall in following a period of time, root are predicted using random theory
The production confluence amount that each sub-district in city is calculated according to the spatial and temporal distributions obtains each sub-district in city based on remittance flow rate calculation is produced
The displacement of branch pipe network；
The displacement of the branch pipe network of step 3, each sub-district in city being calculated according to step 2, according to the displacement
Size the branch pipe network of each sub-district is linked into level-one main pipe net, second level main pipe net, in three-level main pipe net accordingly respectively.
The beneficial effects of the present invention are: system of the invention using three kinds of grades and mutually independent main pipe net make it is each
The branch pipe network of sub-district is schedulable to be linked into main pipe net, so that draining is more efficient, meanwhile, the dispatching party of the invention
Method, it is contemplated that the rain fall in each sub-district future is realized using system of the invention to efficient draining.
Detailed description of the invention
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described.Obviously, described attached drawing is a part of the embodiments of the present invention, rather than is all implemented
Example, those skilled in the art without creative efforts, can also be obtained according to these attached drawings other designs
Scheme and attached drawing.
Fig. 1 is the system diagram of the invention drainage pipeline networks.
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to design of the invention, specific structure and generation clear
Chu is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair
Bright a part of the embodiment, rather than whole embodiments, based on the embodiment of the present invention, those skilled in the art are not being paid
Other embodiments obtained, belong to the scope of protection of the invention under the premise of creative work.In addition, be previously mentioned in text
All connection/connection relationships not singly refer to that component directly connects, and referring to can be added deduct according to specific implementation situation by adding
Few couple auxiliary, to form more preferably coupling structure.Each technical characteristic in the invention, in not conflicting conflict
Under the premise of can be with combination of interactions.
Embodiment 1, with reference to Fig. 1, a kind of drainage pipeline networks of Urban Flood Waterlogging, comprising: several pipe networks, level-one main pipe
Net, second level main pipe net, three-level main pipe net, between branch pipe network mutually independence and be laid on city each sub-district underground, it is described
Level-one main pipe net, second level main pipe net, three-level main pipe net are connected to gathering ground respectively, the level-one main pipe net, second level main pipe net, three
Grade main pipe net is independent mutually, and the designed displacement of the level-one main pipe net is maximum, and the designed displacement of second level main pipe net takes second place, and three
The designed displacement of grade main pipe net is minimum, and the level-one main pipe net, second level main pipe net, three-level main pipe net pass through gate and each respectively
A branch pipe network connection.
When flood occurs for city, the rainwater of sub-district where branch pipe network is collected, and main pipe net is flowed to, due to this system
Main pipe net with three types, comprising: level-one main pipe net, second level main pipe net, three-level main pipe net, when the main pipe net of three types
It is independent mutually, therefore, the corresponding branch pipe network of each sub-district can be selected to do with different grades of according to the rain event of each sub-district
Pipe network connection, since the displacement that level-one does design of pipe networks is maximum, the displacement that second level does design of pipe networks takes second place, three-level main pipe net
The displacement of design is minimum, therefore, when the branch pipe network displacement of some sub-district is larger, is accessible to level-one main pipe net, other
The branch pipe network of sub-district can accordingly be linked into second level main pipe net or three-level main pipe net, since the main pipe net of three kinds of grades is independent mutually,
Therefore, it does not interfere with each other between the main pipe net of three kinds of grades, so that the branch pipe network of each sub-district can efficiently be flowed into gathering ground, keeps away
Exempt from urban waterlogging.
As optimization, the gathering ground and level-one main pipe net, second level main pipe net are equipped with Flow Limit between three-level main pipe net
Check door.The flow for entering gathering ground can be limited by flow restriction gate, prevent gathering ground from rising suddenly and sharply.
Meanwhile the invention additionally provides a kind of drainage pipeline networks dispatching method of Urban Flood Waterlogging, comprising:
City is divided into several sub-districts by step 1, the geographical conditions according to city, several sub-districts respectively
Lower independent laying branch pipe network；
Step 2 is laid with mutually independent level-one main pipe net, second level main pipe net, three-level main pipe net, and by level-one main pipe net,
Second level main pipe net, three-level main pipe net and each pipe network form the drainage pipeline networks of the invention.
Step 3 is based on weather forecast, and the spatial and temporal distributions of rainfall in following a period of time, root are predicted using random theory
The production confluence amount that each sub-district in city is calculated according to the spatial and temporal distributions obtains each sub-district in city based on remittance flow rate calculation is produced
The displacement of branch pipe network；The random theory includes Monte Carlo method or point collocation.
Illustrate the specific embodiment of this step with Monte Carlo method below:
Based on weather forecast, following 1 hour, 2 hours, 4 hours, the maximum drop of 6 hour each sub-districts are obtained
Rainfall, and calculate separately following 1 hour, 2 hours, 4 hours, 6 hour in corresponding apparitions；When according to the predicting interval
Between the duration of raining of quasi- prediction is divided into each period, construct following 1 hour respectively, 2 hours, 4 hours, 6
The rainfall model of hour each period, rainfall model can be used Chicago rainfall pattern, obtain each sub-district by rainfall model
Confluence amount is produced, knows following 1 hour, 2 hours, 4 hours, the branching pipe of 6 hour each sub-districts based on confluence amount is produced
Displacement.
The displacement of the branch pipe network of step 4, each sub-district in city being calculated according to step 3, according to the displacement
Size the branch pipe network of each sub-district is linked into level-one main pipe net, second level main pipe net, in three-level main pipe net accordingly respectively.From
And realize the rational management to drainage pipeline networks.
Better embodiment of the invention is illustrated above, but the invention is not limited to the implementation
Example, those skilled in the art can also make various equivalent modifications on the premise of without prejudice to spirit of the invention or replace
It changes, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
