Abstract

The utility model relates to an infiltration irrigation pipe and is characterized in that: at least one overflow wall with water overflow holes is arranged in the pipe; the overflow wall and the pipe wall form an overflow cavity and an overflow groove seam is positioned at the pipe of the corresponding overflow cavity part. The overflow pipe is arranged under the ground and communicated with the main pipe; the water flows into the overflow cavity through the overflow hole, steams and distributes evenly in the long cavity, overflows through the overflow groove seam and forms a line map contact with the soil, therefore, the soil is wetted more evenly and the utility model can meet the growing demand of more plants. The utility model has simple structure and reasonable design, is more suitable for the growth of plant roots for the pipe is arranged under the ground and the water wets the soil by infiltration; besides, water in the soil during high-temperature and drought climate evaporates very easily and the steam part arising from the ground is absorbed by the surface soil so as to further reduce water loss.

Description

A kind of pipe for osmotic irrigation

Technical field:

The utility model belongs to agriculture field, the pipe for osmotic irrigation that particularly a kind of water-saving irrigation is used.

Background technology:

Flood irrigation is the important means that traditional farming is irrigated, and along with the shortage of water resource, the flood irrigation form is the needs of incompatibility modern agriculture more and more.The awkward situation of reply water resource anxiety, a large amount of manpower studies's water-saving agriculture are dropped in each department, as: drip irrigation technique and foliar spray water irrigation technology.Drip irrigation technique is to utilize pipe network to carry the water source, and by infiltration hole drop water outlet, the infiltration hole generally is laid in top, the face of land, and closely by plant, for plant growing provides continually and enough water sources.Drip irrigation is the technology of comparatively advanced at present and water saving, compare with the traditional irrigation mode and can save water resource in a large number, but its infiltration hole EXIT POINT is too high, splash into and very long down infiltration from ground surface, in the high temperature and drought environment, the moisture that is exposed to the face of land very easily evaporates, and has the defective of moisture loss equally, and, limit to its utilization face for point-like supplies water.

Summary of the invention:

The purpose of this utility model is a kind of pipe for osmotic irrigation that has the wire capacity of water supply under the face of land that is laid in of design.

Technical solutions of the utility model are achieved in that a kind of pipe for osmotic irrigation, it is characterized in that being provided with at least in the pipeline overflow wall that has spillway hole together, form a spill cavity between overflow wall and duct wall, offer the spilling water line of rabbet joint one on the pipeline of corresponding spill cavity part.Pipe for osmotic irrigation is laid under the face of land and with trunk line and is communicated with, and the water source reaches uniform flow and is distributed in the long chamber in spillway hole flows into spill cavity, and overflows by the spilling water line of rabbet joint and to form wire with soil and contact, and soil is able to more uniform moistening.

The utlity model has simple in structurely, reasonable in design, change traditional drip irrigation technique water source and soil point contact deficiency, produce the wire infiltration, be fit to demand of plant growth widely; Pipeline is distributed under the face of land, and water is more suitable for the plant root growth by the moistening soil of infiltration; In addition, the moisture in the high temperature and drought weather soil very easily evaporates, and the water vapour part that rises down in the face of land is absorbed by surface soil, further reduces moisture loss.

Embodiment:

With reference to Fig. 1 pipe for osmotic irrigation structure one sectional view, it is to be provided with the overflow wall 2 that has spillway hole 21 together in pipeline 1 at least, forms a spill cavity 3 between overflow wall 2 and duct wall, offers one the spilling water line of rabbet joint 11 on the pipeline 1 of corresponding spill cavity 3 parts.Be provided with symmetrical twice overflow wall 2 among the figure in the pipeline 1, form the two symmetrical spill cavities 3 and the two symmetrical spilling water lines of rabbet joint 11, but in the pipeline 1 placing flat face of land, the both sides spilling water line of rabbet joint 11 provides twice wire spilling water band, can even moistening larger area soil, if plant in twice wire water band, plant can obtain sufficient moisture.And the pipe for osmotic irrigation of the single road spilling water line of rabbet joint 11 structures also can be gone up laying with the spilling water line of rabbet joint 11, more near plant root.Pipeline 1 can have the expensive low characteristics of production efficiency by forming materials such as plastic cement, and spillway hole 21 adopts mechanical secondary drilling to form.1 one-tenth cylindrical structure of pipeline, match with it directly, annexes such as elbow or three-way connection can be under unified central planning with existing pvc pipe road annex, saves manufacturing cost, increases versatility.

With reference to Fig. 2 pipe for osmotic irrigation structure two sectional views, on the basis of Fig. 1, be inserted with a drainage sheet 4 in the

spill cavity

3,4 anti-sands of drainage sheet are blocked spill cavity 3, and can play the uniform flow effect, make spillway hole 21 point-like water outlets be transformed into wire.

With reference to Fig. 3 pipe for osmotic irrigation structure three sectional views, be inserted with a current limliting plug 5 on spillway hole 21 on the basis of Fig. 1.Because the hydraulic pressure difference at place, pipeline 1 nearly far water source, the aperture of spillway hole 21 also should be different, can adjust by current limliting plug 5.

Described current limliting plug 5 is made for plastic cement, is provided with T shape water channel 51 in it.Different water channel bore water flows is also different, and the effect of current limliting plug 5 also has drainage sheet 4 and similarly acts on.

Described current limliting plug 5 also can be fibrous material and makes, and utilizes the permeance property of fibrous material to reach the purpose of regulating water outlet.

Described current limliting plug 5 is made for ceramic material, and its effect and fibrous material are together.

With reference to Fig. 4 pipe for osmotic irrigation three-dimensional structure diagram, be to be example with Fig. 3 structure, all effects outside managing of spillway hole 21 and current limliting plug 5.
