Product Introduction:156-2152-1000 Manager Shao
Composite geomembranes use plastic films as the impermeable substrate, compounded with non-woven fabrics to form a geosynthetic impermeable material. Its impermeability mainly depends on the impermeability of the plastic film. The commonly used plastic films for impermeable applications at home and abroad mainly include polyvinyl chloride ( PVC), polyethylene (PE), and ethylene/vinyl acetate copolymer (EVA). They are high-molecular chemical flexible materials, with low specific gravity, strong elongation, high adaptability to deformation, corrosion resistance, low-temperature resistance, and good frost resistance.
The service life of composite geomembranes mainly depends on whether the plastic film loses its impermeable water barrier function. According to Soviet national standards, the thickness of polyethylene film with stabilizers used for hydraulic engineering is 0.2m. Under clear water conditions, the service life can reach 40-50 years, while under sewage conditions, the service life is 30-40 years. Therefore, the service life of composite geomembranes is sufficient to meet the service life requirements for dam impermeability.KKolps33378
Technical Requirements for the Installation of Composite Geomembranes: Huainan Drainage Board Manufacturer 156-2152-1000 Manager Shao
Installation should be carried out in dry and warm weather. To facilitate splicing and prevent stress concentration, composite geomembranes should be laid using a wavy relaxation method, with a surplus of about 1.5%. After laying, it should be promptly leveled and spread out, ensuring the composite geomembrane fits flat with the slope, without any protruding wrinkles. Construction personnel should wear flat-soled cloth shoes or soft rubber shoes, and wearing spiked shoes is strictly prohibited to avoid damaging the geomembrane. If any damage to the geomembrane is found during construction, it should be repaired promptly.156-2152-1000 Manager Shao
During transportation, composite geomembranes should not be dragged or pulled hard to avoid puncturing by sharp objects.
The base surface must be cleaned according to design requirements, which is key to ensuring impermeability, especially for removing sharp stones, tree roots, and other debris. The base surface must not have local concave or convex areas, and the cleaned surface should be compacted tightly with a rammer or plate compactor to make itsolid and flat.156-2152-1000 Manager Shao
During transportation, composite geomembranes should not be dragged or pulled hard to avoid puncturing by sharp objects.
1, Should extend from the bottom to the high position, do not pull too tight, leave a surplus of 1.50% for local subsidence stretching. Considering the actual situation of this project, the installation sequence for the slope is from top to bottom;
2, The longitudinal joints of adjacent panels should not be on the same horizontal line but should be staggered by 1m or more;
3, Longitudinal joints should be located more than 1.50m from the toe and bend of the dam, and should be placed on a flat surface;
4, First the slope, then the base;KKolps33378 Huainan Drainage Board Manufacturer
5, During slope installation, the direction of the membrane should be basically parallel to the major slope line.
Huainan Drainage Board Manufacturer Scope of Construction:156-2152-1000 Manager Shao
The Zhouzhou Reservoir dam was originally a core wall dam, but due to dam failure, it caused disconnection in the upper part of the core wall. To solve the impermeability issue in the upper part, a seepage control sloping wall was added.156-2152-1000 Manager Shao
According to the safety verification analysis of this Zhouzhou Reservoir dam, to address the leakage weak zones caused by multiple landslides of the dam and leakage from the dam foundation, vertical seepage control was implemented through bedrock curtain grouting, contact surface grouting, and backfill curtain and high-pressure impermeable wall formations. The upper sloping wall area uses composite geomembranes for impermeability, connecting with the vertical impermeable wall and extending up to 358.0m elevation.
