Geomembranes play many roles in water-saving irrigation by improving anti-seepage effects, extending project life, reducing costs, facilitating construction, intercepting moisture, controlling flow, and improving soil quality.
How does geomembrane play a role in water-saving irrigation?
Significant anti-seepage effect: Geomembrane has excellent anti-seepage performance, and its anti-seepage effect is far better than that of simple concrete anti-seepage materials and earth canal anti-seepage materials. This excellent anti-seepage performance can effectively prevent the loss of irrigation water during transportation and infiltration, and improve irrigation efficiency.
Extend the service life of the project: The application of geomembrane materials can significantly extend the service life of the canal project. Because geomembranes have good corrosion resistance and aging resistance, they can resist the erosion of various environmental factors, thereby protecting the canal structure from damage.
Reduce costs: Compared with simple concrete anti-seepage materials, geomembrane materials have certain advantages in cost. When geomembranes are used as a protective layer of the concrete anti-seepage layer, the thickness of concrete can be reduced, thereby saving material costs. At the same time, although it may be necessary to purchase additional auxiliary materials such as geotextiles, in the long run, this will help reduce the costs caused by frost heave damage and maintenance management.
Convenient construction: Geomembrane has high flexibility during construction. For the anti-seepage renovation project of the old canal, geomembranes can be constructed by adopting plate-membrane composite structures and other methods, which not only avoids the contradiction between construction and water flow, but also shortens the construction period and reduces investment.
Intercepting water: Geomembrane can effectively intercept water sources such as rainwater and sewage to prevent them from entering the irrigation system or groundwater system, thereby reducing the waste and loss of water resources. This is of great significance for protecting water resources and maintaining ecological balance.
Control flow: Geomembrane can adjust the flow and pressure of water according to irrigation needs to achieve precise irrigation. This can not only improve irrigation efficiency, but also reduce waste caused by excessive irrigation.
Improve soil quality: Geomembrane can cover the soil surface during laying, reducing the evaporation and loss of soil moisture. At the same time, geomembrane can also improve soil structure to a certain extent, increase soil fertility and water retention, thereby improving the yield and quality of crops.
