Product Applications:
I. Hydraulic Engineering
Dike and River Channel Treatment: Used for reinforcing the slopes of dikes and the filter layer of the dike foundation to prevent seepage failure of soil; in river channel regulation, it serves as a slope protection cushion to resist the scouring of water flow. Reservoir and Channel Seepage Prevention: Combined with geomembrane to form a "two - layer fabric and one - layer membrane" structure, used for the seepage prevention layer of reservoir dams and irrigation channels, and provides reinforcement support at the same time. Flood Control and Emergency Rescue: Reinforcement and water filtration of temporary cofferdams and flood - control dikes, quickly blocking sediment and draining water.
II. Traffic Engineering
Highway and Railway Subgrades: Laid between the subgrade and the foundation to enhance subgrade bearing capacity, disperse loads, and reduce settlement (such as soft soil foundation treatment). Slopes and Retaining Walls: Used as reinforcement materials in slope protection to prevent landslides; the filter layer on the back of the retaining wall drains water and prevents soil loss at the same time. Airport and Port Engineering: Reinforce the foundation of airport runways, and use for filtration and reinforcement of the revetments of port terminals to resist ship loads and wave impacts.
III. Environmental Protection Projects
Landfill: It serves as the protective layer of the anti-seepage system at the bottom of the landfill, preventing the geomembrane from being punctured by sharp objects and assisting in drainage at the same time. Sewage Treatment Project: It is used for the reinforcement and filtration of the base of sewage treatment tanks and oxidation ponds. Its chemical corrosion resistance is suitable for the sewage environment. Mine and Ecological Restoration: It is the filter layer of the mine tailings dam, fixes the vegetation soil in the ecological slope greening, and prevents soil erosion.
IV. Municipal and Construction Engineering
Underground Engineering: Ground reinforcement for subway tunnels and underground utility tunnels to reduce soil deformation during construction. Landscaping: Drainage layer for flower beds and golf courses, soil reinforcement for park walkway foundations to maintain terrain stability. Filling Engineering: Reinforcement material for backfilling building foundations, improving the integrity and bearing capacity of filled soil.
V. Energy Engineering
Oil and Gas Pipelines: Reinforce the foundation during pipeline laying to prevent pipeline damage caused by soil settlement. Nuclear Power Plants and Hydropower Generation: Foundation treatment for nuclear power plant sites, and the filter and anti-seepage systems for hydropower station dams.
VI. Special Engineering Scenarios
Military Engineering: Rapid reinforcement of temporary fortifications and military roads to meet emergency construction requirements. Desert and Permafrost Areas: Windbreak, sand fixation, and reinforcement of desert highway foundations, and anti-freezing and swelling reinforcement treatment of projects in permafrost areas.
