Composite geomembrane is a new type of engineering waterproof material. It mainly uses polyvinyl chloride (PVC) or polyethylene (PE) plastic film as a waterproof substrate, combined with a non-woven fabric to form a geotechnical waterproof material. Application advantages such as resistance to traction, tear resistance, wear resistance, frost resistance, strong extensibility, corrosion resistance, etc., as a new type of water saving and seepage prevention in water conservancy projects (such as reservoirs, dams, canals, river embankments, etc.) The addition of new reinforcement materials has been widely promoted and applied.

Judging from the practice of canal seepage prevention projects in rural irrigation areas, the use of conventional anti-seepage materials such as clay, cement soil, mortar, masonry, and concrete for seepage prevention and reinforcement is often accompanied by an increase in construction difficulty. Comprehensive cost and poor anti-seepage effect In response to major problems, the new composite geomembrane anti-seepage material is adopted, which has the characteristics of light weight, convenient construction and higher cost performance.






Aiming at the adaptability of water-saving irrigation engineering to soil and site geology, a new type of anti-seepage composite material was prepared, and the core waterproof blanket preparation technology was adopted to solve the problems of easy collapse and low bearing capacity of traditional water-saving irrigation channels in irrigation areas. Improve the safety and sustainability of water-saving irrigation projects. Evaluate the planting effect of anti-seepage engineering plants, do a good job of green ecology, choose plants that are suitable for the environment and easy to grow, build a good ecosystem, and carry out green projects. Water Saving Irrigation. Compared with traditional construction methods, a comprehensive economic analysis of water-saving irrigation projects is carried out, and the economic evaluation results of water-saving irrigation projects in irrigation areas are obtained.

The project transforms hard slope protection to soft slope protection, which can reduce the damage to the canal by hydrogeological phenomena such as pipelines and collapses, and carry out "wet expansion" (expansion water film impermeable)), "dry-out water retention" (with Conducive to the growth of ecological plants) The function of purifying water quality, alleviating agricultural non-point source pollution, and has a certain landscape effect.
