The utility model adopts the following technical scheme:
a device for improving and treating saline-alkali soil comprises a water collecting pipe, a water collecting well communicated with the water collecting pipe and a drain pipe communicated with the water collecting well; the water collecting pipes are uniformly distributed around the water collecting well, the bottom surface of the water collecting well is lower than the bottom surfaces of the water collecting pipes, and the bottom surface of the water discharging pipe and the bottom surface of the water collecting well are coplanar.
The water collecting pipe comprises a semi-annular water conveying ring and a semi-annular water permeable ring which are arranged on the same circumference, geotechnical cloth is arranged in the water conveying ring, and fine sand and a plurality of water permeable pipes which are arranged in the fine sand and are parallel to the axis of the water collecting pipe are arranged in the water permeable ring.
Furthermore, the water collecting pipes are distributed on two sides of the water collecting wells, and the water collecting wells are linearly arranged.
Furthermore, the water delivery ring is a semicircular PVC pipe.
Further, the water permeable ring is a semi-annular nylon net or a stainless steel net.
Furthermore, the ratio of the diameter of the water permeable pipe to the diameter of the water collecting pipe is 1: 15-25.
Furthermore, the connection part of the water collecting pipe and the water collecting well extends towards the water collecting well through the geotextile and is attached to the inner wall of the water collecting well.
Further, the permeable pipe is a soft permeable pipe.
The beneficial effects of the utility model reside in that: the water and soil loss caused by the conventional soil washing process is avoided by utilizing the pipe network to discharge water outside the area. After the pipe network is laid, the soil washing operation is more convenient, the corrosion resistance of the whole device is good, the whole device can be repeatedly used throughout the year, and the soil treatment of stubborn salinization is more facilitated.

Detailed Description
The present invention will be further described with reference to several embodiments, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all such changes and substitutions are intended to be covered by the scope of the present invention.
A device for improving and treating saline-alkali soil comprises a water collecting pipe, a water collecting well 1 communicated with the water collecting pipe and a drain pipe 2 communicated with the water collecting well 1; the water collecting pipes are uniformly distributed around the water collecting well 1, the bottom surface of the water collecting well 1 is lower than that of the water collecting pipes, and the bottom surface of the water discharging pipe 2 is coplanar with that of the water collecting well 1. The water collecting pipe is buried 2m under the soil, the upper edge of the water collecting well is higher than the ground surface, and the well depth of the water collecting well is not less than 2.5 m. The saline-alkali soil is injected with water, and after the saline-alkali soil is soaked by water, the salt in the surface soil can be dissolved in the water and collected into the water collecting well along with the water collecting pipe, and the salt is discharged through the water discharging pipe, so that the effect of washing the salt in the soil is achieved.
The water collecting pipe comprises a semi-annular water conveying ring 3 and a semi-annular water permeable ring 4 which are arranged on the same circumference, geotechnical cloth 5 is arranged in the water conveying ring 3, and fine sand 6 and a plurality of water permeable pipes 7 which are arranged in the fine sand 6 and are parallel to the axis of the water collecting pipe are arranged in the water permeable ring 4. The water containing salt alkali in the soil firstly enters the fine sand through the water permeable ring, the water permeable ring is a semicircular nylon net or a stainless steel net, the mesh number of the nylon net is matched with the particle size of the fine sand, sand leakage is prevented, large particles are prevented from entering the fine sand, the particle size of the fine sand is not selected to be too small, the fine sand is preferably 1-2 mm, and the water blocking effect is too strong due to too small particle size, so that permeation is affected. The fine sand is filtered for the second time and then enters the soft permeable pipe, the soft permeable pipe comprises a net-shaped framework which is spirally woven by alloy high-carbon steel wires, the non-woven fabric covers the net-shaped framework to serve as a filter layer, the soft permeable pipe flows into the water delivery ring after being further filtered by the soft permeable pipes, the water delivery ring is filled with geotextile, the geotextile has excellent water absorption and water guide effects, water is guided out of the water collection pipe, soluble salt is discharged, and the loss of water and soil is avoided.
The water collecting pipes are distributed on two sides of the water collecting well 1, and the water collecting wells 1 are linearly arranged. The water delivery ring 3 is a semicircular PVC pipe. The permeable pipe 7 is a soft permeable pipe. The ratio of the diameter of the water permeable pipe 7 to the diameter of the water collecting pipe is 1: 15-25. The pipe of permeating water can be each other the direct packing that parallels in the ring that permeates water to add the stifled gap with fine sand, make whole receipts water pipe closely knit firm, not fragile.
The joint of the water collecting pipe and the water collecting well 1 and the geotextile 5 extend towards the inside of the water collecting well 1 and are attached to the inner wall of the water collecting well 1. The geotextile has stronger water absorption, and after the end part of the geotextile is attached to the inner wall of the water collecting well, water flows into the water collecting well through the geotextile more easily under the action of siphon and the gravity of the water, thereby being more beneficial to drainage.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the present invention.
