Green ecological construction water-saving irrigation system
Technical field
The utility model relates to a kind of irrigation pipeline, especially relates to a kind of green ecological construction water-saving irrigation system.
Background technology
Irrigate and green ecological construction is had great significance, China is a large agricultural country, Water Consumption in Agriculture accounts for 63% of whole water consumption, but the water resource wretched insufficiency of China, lack of water constrains the development of China's arid, semiarid zone greening to a great extent, along with the expansion of global warming and scale of agricultural production, the trend of China's drought and water shortage is quite severe.When irrigated farmland, a lot of water is seepage, evaporation in water delivery, water distribution, the process of pouring water, therefore its water use efficiency is lower.Furrow irrigation is topmost surface irrigation mode, and its water-saving result is remarkable, have save energy, easy and simple to handle, to water quality requirement not advantages of higher, but its uniformity of irrigation water appilcation wayward, pour water shortcoming of low quality also clearly.
It is the furrow irrigation combined with ground film coating technique that film ditch is irrigated, and it in irrigation ditch, forms furrow membrane by being applied ointment or plaster by the mulch film with water seepage hole, and irrigation water flows on furrow membrane, and infiltrates soil by fenestra.The insulation soil moisture conservation effect of mulch film the infiltrating irrigation of film ditch is had good water-saving result, irrigation water using efficiency are high, mulch film avoids irrigation water washing away soil in ditch, decrease moisture loss.But the infiltrating irrigation of existing film ditch affects by physical features, the gradient, and the delivery port of infiltrating irrigation pipe easily blocks, it exists when seepage, water easily oozes out the root that fully cannot accumulate in crops from hollow billet bottom, cause water to be absorbed by crops fully, thus causes the loss of water resource to waste.In addition, existing film ditch is irrigated still has the uneven phenomenon of irrigation to happen occasionally.
Summary of the invention
The utility model object is to provide one and is not subject to the influence of topography, not easily blocks, irrigates uniform green ecological construction water-saving irrigation system, affect greatly to solve the infiltrating irrigation of existing film ditch by landform, the gradient, infiltrating irrigation pipe delivery port easily blocks, and exists and irrigates the technical problems such as uneven.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of green ecological construction water-saving irrigation system, comprise the pipe network that infiltrating irrigation pipe is interconnected to constitute, the tube wall of described infiltrating irrigation pipe is provided with multiple seepage mouth, is arranged with filter screen outside infiltrating irrigation pipe; The terminal of described infiltrating irrigation pipe is connected with filter chamber, and filter chamber is connected with sparge pipe, gas-distribution pipe respectively, is provided with filtration core in filter chamber, and filtration core covers the entrance of infiltrating irrigation pipe terminal; Described gas-distribution pipe is connected with high-pressure pump, and described sparge pipe is connected with water pump by pipeline.
As preferably, described infiltrating irrigation pipe is arranged on below the layer of turning over of agricultural land soil, and bottom infiltrating irrigation pipe, tube wall is outside equipped with semi arch PVP film, and described PVP film is be synthetic by PVC+PP material.
As preferably, described seepage mouth is aperture or narrow slit.
The utility model has that water-saving rate is high, the not susceptible to plugging advantage of infiltrating irrigation pipe.Flowed out by the seepage mouth on infiltrating irrigation pipe tube wall by the irrigation water after filtration core in filter chamber filters.Filter screen outside infiltrating irrigation pipe pipe can prevent the impurity blocking seepage mouth outside pipe, ensures the uniformity of infiltrating irrigation.Multiple micropores on infiltrating irrigation pipe are that infiltrating irrigation does not block, and lifespan is long, and by water pump not by the restriction of water level height, the utilization of water resource is very abundant, and do not evaporate at the water of lower floor's infiltrating irrigation of soil, the infiltrating irrigation pipe of utilization is drawn materials very easily, easily promotes on a large scale.PVP film can save a small amount of water simultaneously, and what keep soil has certain humidity, and moisture fully can accumulate in the root of green plants, is absorbed by green plants.This utility model well improves the deficiencies in the prior art, has good promotional value.

Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
Embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
Shown in composition graphs 1,2, this green ecological construction water-saving irrigation system, comprises pipe network, filter chamber 4 etc. that infiltrating irrigation pipe 1 is interconnected to constitute.The embedded section tube wall upper tube wall of its infiltrating irrigation pipe 1 is provided with multiple seepage mouth 2, and seepage mouth 2 is aperture or narrow slit.Filter screen 3 is arranged with outside infiltrating irrigation pipe 1.Infiltrating irrigation pipe 1 terminal and filter chamber 4, filter chamber 4 is connected with sparge pipe 5, gas-distribution pipe 7 respectively, is provided with filtration core 8 in filter chamber 4, and filtration core 8 covers the entrance of infiltrating irrigation pipe 1 terminal, and gas-distribution pipe 7 is connected with high-pressure pump 9, and sparge pipe 5 is connected with water pump 10 by pipeline.
Be embedded with ground overlay film bottom green ecological construction water-saving irrigation system, flowed out by the seepage mouth on infiltrating irrigation pipe 1 tube wall by the irrigation water after filtration core 8 in filter chamber 4 filters.Filter screen 3 outside infiltrating irrigation pipe 1 pipe can prevent the impurity blocking seepage mouth outside pipe, ensures the uniformity of infiltrating irrigation.Multiple micropores on infiltrating irrigation pipe 1 are that infiltrating irrigation does not block, lifespan is long, by water pump 10 not by the restriction of water level height, infiltrating irrigation pipe 1 is arranged on below the layer of turning over of agricultural land soil, and the embedded section of infiltrating irrigation pipe 1 is provided with multiple micropore, and bottom infiltrating irrigation pipe 1, tube wall is outside equipped with semi arch PVP film 6, can prevent water in infiltrating irrigation pipe 1 from oozing out, PVP film 6 for being by the synthetic of PVC+PP material, be a kind of high density, unprotected side chain, high crystallization must linear polymer, there is excellent combination property.Be white translucent time not painted, wax-like; Lighter than polyethylene.Also comparatively polyethylene is good for transparency, harder than polyethylene.Can be inflated irrigation water by the sparge pipe 5 in filter chamber 4, gas-distribution pipe 7, improve oxygen content in irrigation water, be conducive to the growth quality improving soil quality and plant, flowed out by the seepage mouth 2 on infiltrating irrigation pipe 1 tube wall by the irrigation water after filtration core 8 filters.Filter screen 3 outside infiltrating irrigation pipe 1 pipe can prevent the impurity blocking seepage mouth outside pipe, slows down and water speed, ensure the uniformity of film ditch infiltrating irrigation.Filter screen 3 can adopt absorbent material to make, and irrigation water can spread to pipeline surrounding, the effect of impregnation especially above pipeline.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-mentioned embodiment, can also have many distortion.Every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all should think and belong to protection domain of the present utility model.
