Geo-Tube
1.Efficient Dewatering:
The geotextile allows water to seep out while retaining solid particles, accelerating sludge dewatering.
2.Cost-Effective & Eco-Friendly:
Compared to traditional cofferdams or concrete structures, it offers lower costs and reduces carbon emissions.
3.Easy Installation:
Adaptable to complex terrains, requiring no heavy machinery, and forms a stable structure directly after filling.
4.High Durability:
UV-resistant and corrosion-resistant, suitable for harsh environments.
Product Introduction:
Geo-Tube is a large tubular container made of high-strength geotextile fabric. It is filled with slurry, sludge, or fine-grained materials through hydraulic filling technology. By utilizing the filtration and drainage functions of the fabric, it achieves solid-liquid separation and ultimately forms a stable geotechnical structure.
Product Features
Material: Made of high-strength woven/non-woven geotextile fabric (PP or PET) with excellent tensile strength and permeability.
Specifications: Typically 1~5 meters in diameter, with customizable length (up to several tens of meters).
Filtration Performance: Controlled pore size ensures effective retention of fine particles while enabling rapid drainage.
Flexible Structure: Adapts to ground deformation, offering superior seismic resistance compared to rigid structures.
