Application of HDPE geomembrane in water conservancy projects
The application of HDPE geomembrane in water conservancy projects has significant advantages in anti-seepage, corrosion resistance and adaptability to geological changes.
Water reservoir and dam anti-seepage
1. Construction of anti-seepage layer
HDPE geomembrane is used at the bottom of reservoirs and dam structures to effectively prevent leakage and extend service life. For example, when laying at the bottom of a reservoir, it is necessary to combine a protective layer (such as block stone or concrete) to enhance impact resistance.
2. Vertical core wall and slope protection
In dam construction, HDPE geomembrane can be used as a vertical anti-seepage core wall or for slope protection to prevent water erosion and infiltration.
Channel and river anti-seepage
1. Irrigation channel repair
HDPE geomembrane can replace traditional concrete lining to repair aging channels. During construction, lock strips need to be pre-buried and anchored with concrete to adapt to foundation settlement.
2. River management
Used for river anti-seepage and slope protection to reduce soil erosion. For example, in artificial lakes or reservoirs, HDPE geomembrane can be used as a waterproof liner to prevent water evaporation and leakage.
Water storage projects and artificial lakes
1. Water storage tank anti-seepage
HDPE geomembrane is used in drinking water pools, reservoirs, etc. to ensure water quality safety. When laying, it is necessary to reserve a stretch margin (1.5%), and use hot melt welding to ensure the strength of the weld.
2. Artificial lake construction
As the bottom anti-seepage layer, HDPE geomembrane can resist water pressure and microbial erosion, and at the same time, combined with a rough surface design to enhance friction and prevent sliding.
Key points of Construction Technology
1. Base surface treatment
The base layer needs to be compacted ≥95%, the surface should be flat without sharp objects, and the slope should be smoothly transitioned to avoid stress concentration.
2. Welding process
Hot melt welding is recommended, the temperature should be controlled at 280-300℃, and the weld strength should reach more than 90% of the parent material. The welder needs to be preheated during low-temperature construction.
3. Laying specifications
Extend from low to high, and the longitudinal joints should be staggered by more than 1m to avoid the corner area. After laying, an inflation test (0.06Mpa pressure) is required to ensure sealing.
