Abstract

A subsurface irrigation system mainly solves the problems that a subsurface irrigation pipe is blocked, pressure of the subsurface irrigation pipe is not balanced and the like in an existing subsurface irrigation technique. The subsurface irrigation system mainly comprises a well and the like. A water pump outlet is communicated with a water tank, a filter, a fertilizing device, a pressure gauge and a flow meter through a sand filter, and is communicated with a main pipe through a control valve. A main pipe terminal is communicated with a draining well, the main pipe is communicated with secondary pipes through crosses branches, the secondary pipes are connected with branch pipes which are distributed in parallel, a plurality of drip lines are communicated with each two branch pipes distributed in parallel, and water-permeable holes are evenly formed in the drip lines. Non-woven cloth winds outside the drip lines, the drip lines are paved underground, and the highest point of each drip line is provided with an automatic air exhausting valve. The subsurface irrigation system has the advantages that water enters from two sides of each drip line due to reasonable arrangement, pressure loss of the drip lines due to water penetration is reduced, and therefore the whole system can supply water to roots of crops at stable pressure. Due to the fact that the non-woven cloth winding on the drip lines isolates the drip lines from soil, the blocking and pollution problems of the drip lines caused by the soil.

Description

A kind of infiltrating irrigation system

Technical field

The utility model relates to a kind of agricultural water-saving irrigation system, is specifically related to a kind of infiltrating irrigation system.

Background technology

Infiltrating irrigation is the sprinkling irrigation that continues, a kind of new and effective subsurface irrigation technology after the drip irrigation, it is that the infiltrating irrigation pipe that will have uniform micro is embedded in crop root zone, utilize micro pores on the infiltrating irrigation tube wall, under the lower pressure effect, water is oozed out by the mode that is " sweating " in the pipe outside pipe, spread to the soil body at the water sorption capillaceous by the tube wall surrounding soil, reach continuously and supply water to the root of the crop layer, thereby the overall process of implementing the crop growth phase is irrigated, this technology has the water-saving rate height, do not evaporate seepage loss, do not cause the face of land to harden, suppress weed growth, being convenient to the characteristics of ground farming and cultivation management, is a kind of desirable high-efficiency water-saving technology.The U.S., Israel etc. occupy first place in the world in infiltration irrigation technology research, and China still belongs to the starting stage, and some key technologies also do not obtain fine solution, and as the blockage problem of infiltrating irrigation pipe, infiltrating irrigation pipe pressure imbalance etc. still need people constantly to explore.

Summary of the invention

In order to solve the infiltrating irrigation pipe plug plug that exists in the infiltration irrigation technology, problems such as infiltrating irrigation pipe pressure imbalance the utility model proposes a kind of infiltrating irrigation system, by to the rational deployment of infiltrating irrigation system with to the improvement of infiltrating irrigation pipe, thereby address the above problem.

The technical solution of the utility model is: a kind of infiltrating irrigation system, mainly comprise well, main pipe, hollow billet etc., the well bottom has pipe to be communicated with water pump, exit of pump is by sandstone filter joining water box top, exit of pump has pipeline to be communicated with well top by back-water valve (BWV) in addition, water tank bottom outlet apart from high o'clock of ground greater than more than two meters, filter is passed through in the water tank bottom outlet, fertilizer applicator, manometer, flowmeter and control valve are communicated with main pipe, the main pipe upper end has some through holes, each through hole is communicated with a three-way pipe, this three-way pipe is communicated with a branch main respectively, be connected with branch main valve between this three-way pipe and each the branch main, every group two branch main valves are located in the valve pit, dividing main to pass the valve pit wall is layed in the underground, divide main and main pipe to be to intersect arrangement, have some through holes on each branch main and be communicated with arms, arm with divide main to be to intersect arrangement, be between the arm and be arranged in parallel, between per two arms that are arranged in parallel, be communicated with some hollow billets, evenly have the infiltration hole on the hollow billet, the hollow billet outside is wound with nonwoven.

In the such scheme, main pipe is layed in below the frozen soil layer, main pipe terminal communicated drainage well, and the main pipe terminal is connected with valve in gully.

In the such scheme, it is underground to divide main, arm and hollow billet to be layed in, apart from ground 30～60cm.

In the such scheme, the peak that each hollow billet is laid has through hole and is communicated with automatic exhaust steam valve by pipeline.

The utlity model has following beneficial effect: this a kind of infiltrating irrigation system has adopted the arranged crosswise main pipe, divide main, arm and hollow billet, make hollow billet intake from both sides, reduced the pressure loss that hollow billet produces because of infiltration, infiltrating irrigation intensity is consistent when the same intake pressure, whole infiltrating irrigation system is all supplied water to crop root under the pressure stably at one, isolate hollow billet and soil by twining nonwoven at hollow billet, prevent that effectively soil is to the blocking pollution problem of hollow billet, whole pipe network is embedded in underground and is provided with valve pit and gully, the hollow billet eminence is provided with automatic exhaust steam valve, effectively solves drainage problem and vapour lock problem;

In sum, owing to be directly crop root to be applied fertilizer, supplies water underground, this infiltrating irrigation system has moisture and does not does not scatter and disappear, compares with ground drip irrigation the characteristics that general destruction soil moisture content, soil are difficult for hardening, not influenced by topography and geomorphology, be fit to the irrigation of dry land large scale system, water-saving result is good.
