A TechoTubes are large a tube structures fabricated from high strength woven geotextile with soil-in-fills. Geotextile tube is formed in situ by the hydraulic pumping of local soil into the prefabricated geotextile tube. This leads to a flexible, monolithic, continuous structure that is highly resistant to water currents. Sand is widely used as the soil in-fill material because of its low compressibility but other hydraulically pumped soil types can be used. Geotextile tubes are normally characterized in terms of theoretical diameter.
The geotextile used to make geotextile tubes has fine pore sizes to enable retention of the soil-infill but also has high permeability to enable easy exit of water during the hydraulic filling stage. The geotextile has high tensile strength to enable it to resist the tensile stresses occurring during hydraulic filling and maintain its structure shape.
In dewatering applications TechnoTubes are a reliable, economic and environment-friendly solution. TechnoTube main objective is to recycle waste rather than sending it to a landfill. The solution consists in some Geotextile tube in which are injected some sludge pumped from a waste storage area. Thanks to the filtration properties of the geotextile, the sludge remains into the tubes and the water, separated from the sediments, leaves the tubes. Once dry, solids contained into the Geotextile tube are converted into a filter cake which can be easily recovered.
