Abstract
The utility model discloses an irrigated area canal system system, including water source, trunk canal, branch canal and the drainage system who is located field irrigation area, water source and trunk canal intercommunication, and arrange in the eminence, branch canal and drainage system intercommunication are passed through to the trunk canal, still include wetland system, wetland system passes through branch canal and trunk canal and drainage system intercommunication, the junction of wetland system, drainage system and branch canal all is equipped with the gate that dams. The utility model discloses can effectively improve the water use rate, bring more land under irrigation, realize agriculture high yield, stable yields. After utilizing the engineering measure to store the irrigation return flow, send water to field by the heat -extraction system of ganging up each other, the water facilities that carries who is favorable to very much the dispersion to be flowed launches lifting irrigation simultaneously, makes shorten dramatically irrigation frequency. After the irrigation return flow is developed and used in the irrigated area low reaches, vacate the farmland that the water yield can make the upper reaches and obtain maximum in good time irrigation, alleviated the water contradiction of upper and lower trip.
Description
Technical field
This utility model relates to irrigation and water conservancy field, particularly relates to a kind of irrigated area canal system。
Background technology
Water resources shortage has been global problem, the key constraints of water arid and semi-arid area agricultural production especially。The recirculation of waste water and recycling, be the effective ways solving this contradiction。Return water could be used further to irrigate or other aspects, the composition of harmful substance and concentration contained by return water and determine。
The planning principles of general irrigation canal system is: 1) trunk canal is arranged in eminence, to control larger area；2) layout makes quantities and engineering cost minimum；3) administrative division is considered, independent by water unit and channel as far as possible；4) lateral canal, field ditch meet mechanized farming requirement；5) comprehensive utilization of water resource is considered；6) irrigation canal system is arranged and must be combined with arrangement of Drainage；7) irrigation canal system and land use planning match, and to improve land utilization ratio, conveniently produce and life。
Tibetan area is mainly distributed on arid and semi-arid area, generally dry and rainless, and climate change makes China's Arid&semi-arid area water resource spatial and temporal distributions uneven, and the contradiction of supply and demand for the water resource highlights。China's Arid&semi-arid area generation agricultural arid number of times is increase trend, and agricultural arid greatly constrains China's Arid&semi-arid area agricultural development。
The efficiently utilization with water that effectively keeps that the principle of China's semiarid zone agricultural water resources Appropriate application should be water is laid equal stress on, and " maintenance " is premise, and " utilization " is crucial。Solve semiarid zone agricultural water shortage problem and and then to realize the key link that limited water resources efficiently utilizes be agricultural water conservation。Therefore, the combination of collection rain supplement irrigation and modern dry farming is the inevitable choice of semiarid zone agricultural development。The common difficulty that the water-saving irrigation of semiarid zone and dry farming and water-saving irrigation to be captured is how to improve utilization rate and the utilization ratio of natural precipitation and irrigation water。
Utility model content
The purpose of this utility model is that offer one solves the problems referred to above, is the efficient technique of rainwater utilization approach realizing semiarid zone agricultural limited water resources by improving farmland rainwater use efficiency and utilization ratio, irrigated area canal system。
To achieve these goals, the technical solution adopted in the utility model is: a kind of irrigated area canal system, including water source, trunk canal, branch canal and the drainage system being positioned at field irrigation district, described water source connects with trunk canal, and it being arranged in eminence, described trunk canal is connected with drainage system by branch canal, also includes wet land system, described wet land system is connected with trunk canal and drainage system by branch canal, and the junction of described wet land system, drainage system and branch canal is equipped with the gate that dams。
As preferably, described wet land system is between water source and field irrigation district。
As preferably, the branch canal being connected with wet land system has two, described two branch canal respectively inlet channels and outlet canal, and described inlet channel and outlet canal are equipped with the gate that dams。
As preferably, described inlet channel is positioned at wet land system top, and outlet canal is positioned at wet land system bottom。
As preferably, described wet land system has multiple, and the plurality of wet land system connects with branch canal respectively。
Compared with prior art, the utility model has the advantage of: this utility model can be effectively improved the utilization rate of water, brings more land under irrigation, it is achieved the high yield of agricultural, stable yields。Utilize the gate that dams that the surface runoff that rainfall produces can be made to be unlikely to be pooled to the same period in downstream, alleviate water drainage burden, rainwater storage can also be utilized simultaneously。After having poured water, according to the situation such as weather, crop water, remaining irrigation return flow can be stored。After utilizing works measure stores irrigation return flow, by the heat-extraction system mutually ganged up, water is delivered to field, it is appreciated that the extracting water facility in dispersion flows launches irrigation by pumping simultaneously, makes shorten dramatically irrigation frequency。After downstream, irrigated area develops irrigation return flow, vacateing the water yield and the farmland of upstream can be made in good time to obtain farthest irrigating, what alleviate upstream and downstream uses water contradiction。

Detailed description of the invention
The utility model is described in further detail below。
Embodiment: referring to Fig. 1, a kind of irrigated area canal system, including water source 1, trunk canal 2, branch canal 3 and the drainage system 5 being positioned at field irrigation district, described water source 1 connects with trunk canal 2, and it being arranged in eminence, described trunk canal 2 is connected with drainage system 5 by branch canal 3, by the trunk canal 2 in diversion irrigation irrigated area, ground, water source 1, being spilt out by the moisture in trunk canal 2 by branch canal 3, the drainage system 5 again through branch canal 3 diversion to field irrigation district is irrigated；Also include wet land system 4, the Wetland Environment of wet land system 4 can effectively store diversion or Accumulated Rainwater, described wet land system 4 is connected with trunk canal 2 and drainage system 5 by branch canal 3, described wet land system 4 is between water source 1 and field irrigation district, described wet land system 4, the junction of drainage system 5 and branch canal 3 is equipped with the gate that dams, wet land system 4 connects branch canal 3 or trunk canal 2, when field irrigation district is irrigated after enough, after the irrigation of field irrigation district, unnecessary water can return and be discharged into wet land system 4, when field irrigation district needs to irrigate, irrigation return flow in wet land system 4 is guided to the recycling of field irrigation district。The branch canal 3 being connected with wet land system 4 has two, described two branch canal 3 respectively inlet channels and outlet canal, described inlet channel and outlet canal are equipped with the gate that dams, the gate that dams can carry out diversion and dam, by unnecessary diversion by stream to wet land system 4, or wet land system 4 is opened storage water is restored to field irrigation district。Described inlet channel is positioned at wet land system 4 top, and outlet canal is positioned at wet land system 4 bottom, is conducive to the Inlet and outlet water of wet land system 4 to store。Described wet land system 4 has multiple, and the plurality of wet land system 4 connects with branch canal 3 respectively, can many amount of storage bigger, carry out efficient use of water scheduling。
