Embodiment 1

[0023] Embodiment 1: A multi-layer sand net wrap pipe, including a central water supply pipe for infiltration irrigation 1, with seepage holes 2 evenly opened on both sides of the central water supply pipe for infiltration irrigation The pipe wall of 1 is provided with a coarse sand layer 3, a medium sand layer 4 and a fine sand layer 5 in sequence, the diameters of the sand particles in the coarse sand layer, medium sand layer and fine sand layer decrease successively, and the coarse sand layer 3 and the medium sand layer 4 are separated by the first sand net 6, the middle sand layer 4 and the fine sand layer 5 are separated by the second sand net 7, the fine sand layer 5 is provided with a third sand net 8, the first sand net 6 The mesh diameter of the mesh is smaller than the sand diameter of the middle sand layer 4, preventing the sand particles of the middle sand layer 4 from entering the coarse sand layer 3, and the mesh diameters of the second sand mesh 7 and the third s...

Embodiment 2

[0024] Embodiment 2: A kind of multi-layer sand net wrapped pipe of this embodiment will be described centering on the differences from Embodiment 1;

[0025] Such as Figure 4 As shown, the upper end of the third sand net 8 outside is equipped with a sunshade 13, and the sunshade is an arc-shaped cover that fits with the top of the third sand net. The two sides of the sunshade 13 are welded or fixed to the third sand net 8 by iron wire. Above, the function of the sunshade is to reduce the direct evaporation of water, and at the same time prevent the water flow from spraying out from the upper end of the fine sand layer when the water pressure is too high.

Embodiment 3

[0026] Embodiment 3: A kind of multi-layer sand net wrapped pipe of this embodiment will be described centering on the differences from Embodiment 1;

[0027] Such as Figure 5 As shown, ribs 20 are set on the outside of the third sand net 8, and rib seepage joints 19 are arranged symmetrically on both sides of the rib plates 20. Root zone penetration.

[0028] Embodiment: 4: a kind of multi-layer sand net wrapping irrigation system of the present embodiment is described centering on the difference with embodiment 1;

[0029] A kind of multi-layer sand net guarantee irrigation system, such as Image 6As shown, the water stored in the reservoir passes through the filter device and then passes through the main pipe 14 and a plurality of branch pipes to infiltrate and irrigate the formation, and valves 15 are arranged on the relevant pipelines of the main pipe and the multi-branch pipes, wherein the branch pipes are multi-layer pipes of the present invention. The sand net guar...

Abstract

The invention relates to the technical field of high-efficiency water utilization and agricultural water saving, and specifically relates to a multi-layer sand net wrapping pipe and a multi-layer sandnet wrapping pipe irrigation system. The multi-layer sand net wrapping pipe comprises an infiltration irrigation water pipe, wherein the infiltration irrigation water pipe is provided with seepage holes, a coarse sand layer, a medium sand layer and a fine sand layer with the sand diameter decreasing in sequence are successively arranged around the infiltration irrigation water pipe from inside tooutside, the coarse sand layer and the medium sand layer are separated by a first sand net, the medium sand layer and the fine sand layer are separated by a second sand net, the fine sand layer is externally provided with a third sand net, the end part of the infiltration irrigation water pipe is sleeved with an end sealing plate, the end sealing plate is vertically connected with the infiltration irrigation water pipe, the first sand net, the second sand net and the third sand net, the flow velocity of the water can be controlled, the water flow in the water pipe carries out uniform infiltration irrigation around, the infiltration irrigation efficiency is high, and the blockage prevention effect is good.

Description

technical field [0001] The invention relates to the technical field of water saving in high-efficiency water use agriculture, in particular to a multi-layer sand net-wrapped tube and a multi-layer sand-net wrapped tube irrigation system. Background technique [0002] Seepage irrigation is a form of underground micro-irrigation. This irrigation method uses low-pressure pipelines to deliver water, and then through the irrigator (microporous irrigation pipe) buried in the active layer of the root system of the crops, it is regularly and quantitatively distributed according to the growth water demand of the crops. The water seepage in the soil supplies the crops. Therefore, infiltration irrigation can be regarded as a special form of drip irrigation, also known as subsurface drip irrigation. Compared with other irrigation technologies, infiltration irrigation technology has the advantages of water saving, land saving, labor saving, low energy consumption, etc., and has become t...
