Product Introduction
Composite geomembrane is an impermeable material made by compounding geotextiles with geomembranes. It is mainly used for seepage prevention and is divided into two types: "one-geotextile-one-geomembrane" and "two-geotextiles-one-geomembrane". It has high physical and mechanical property indicators such as tensile strength, tear resistance, and bursting resistance, and can meet the needs of projects in water conservancy, municipal administration, construction, transportation, subways, tunnels, etc. Due to the selection of polymer materials and the addition of anti-aging agents in the production process, it can be used in unconventional temperature environments. It is a geosynthetic material formed by calendering or thermal fusion compounding of one layer of geotextile and one layer of polymer material (usually a membrane material).
Application Purposes
Water Conservancy Engineering: Standard-reaching projects for sea dikes, river dikes, and lake dikes; reservoir reinforcement projects; reclamation projects; flood prevention and emergency rescue.
Highway, Railway and Airport Engineering: Soft foundation reinforcement treatment; slope protection; pavement anti-reflective cracking structural layer; drainage system; green isolation belt.
Electrical Engineering: Nuclear power plant foundation engineering; thermal power ash dam engineering; hydropower station engineering.
Other Applications: Used for reinforcement, strengthening, filtration, and separation in projects such as highways, railways, dikes, and coastal tidal flats. Long-fiber geotextile is particularly suitable for saline-alkali swamps and landfills.
Construction Technology
The rolling method is adopted for manual laying. First, the flatness of the geotextile surface must be ensured during laying, and a certain gap should be reserved in the construction to provide allowance for the material's deformation caused by external forces. At the same time, attention should be paid to taking certain protective measures after installation to prevent substances such as dust and soil from entering the geotextile layer. If needle skipping occurs, the needle-skipped part must be re-sewn and reinforced.
If the laying project is carried out on a slope, the upper end of the actual slope should be fixed during the laying process. After fixing, the long-fiber geotextile is rolled and laid along the slope, and the geotextile surface should be in a taut state after rolling. If the laying surface is flat, sand belts should be used for fixing during the laying process: the sand belt presses one end of the geotextile, and after the laying is completed, the sand belt cannot be removed until the upper layer of material is laid.
