What is a geomembrane?
As an efficient anti-seepage material, geomembrane plays an important role in channel anti-seepage and water-saving renovation projects.
The application of geomembrane can significantly improve the anti-seepage performance and engineering life of the channel, while saving construction costs.
The anti-seepage and water-saving renovation project of canals is an important link in farmland water conservancy projects. Its purpose is to reduce water loss during canal water delivery through anti-seepage technology.
As an ideal anti-seepage material, geomembrane has excellent anti-seepage performance and durability, and has low construction cost.
The anti-seepage performance of geomembrane is mainly reflected in its low permeability coefficient, which can effectively prevent the penetration of liquids.
At the same time, the geomembrane has a certain thickness, which can block the entry of fine particles in the soil, further enhancing its anti-seepage performance.
The use of geomembranes as anti-seepage materials in channels can significantly reduce leakage losses in channels and improve irrigation water efficiency.
What are the characteristics of geomembrane?
Geomembrane has good temperature adaptability, and its operating temperature range is generally between -60~60℃.
When used in cold areas, geomembranes can play a thermal insulation role, reduce frost heave damage to channels, and extend the engineering life of the channels.
At the same time, when used in hot areas, geomembranes can prevent water evaporation in the channel and improve water resource utilization efficiency.
Compared with traditional concrete anti-seepage materials, geomembranes have the advantages of saving construction costs and improving work efficiency.
By using geomembrane as an anti-seepage material, the cost of the project can be reduced while ensuring the quality and effect of the project.
In the channel anti-seepage and water-saving renovation project, appropriate geomembrane materials should be selected according to specific application scenarios and requirements.
How to choose geomembrane material?
Generally speaking, for channels with large water level changes and fast flow rates, PVC materials with higher strength and stronger corrosion resistance should be used.
For channels with small water level changes and slow flow rates, PE materials with lower cost and easy construction can be used.
In addition, factors such as the thickness and mechanical properties of the geomembrane material should also be considered to ensure that it has good anti-seepage performance and durability.
