Basic Introduction to the Use of Geotextile Tubes

Release date:

2021-11-24

Faced with environmental challenges such as the foul odor of river sediments and heavy-metal contamination, China urgently needs to address sediment‑treatment issues. Geotextile tubes—large tubular containers or enclosures made from high‑strength geotextiles—can be customized in diameter to meet specific requirements and can extend up to several tens of meters in length. Originally, geotextile tubes were employed in embankment‑construction projects.

　　Faced with environmental challenges such as the foul odor of river sediments and heavy-metal contamination, China urgently needs to develop a robust sediment‑treatment market. Geotextile tubes—large tubular containers or enclosures made from high‑strength geotextiles—can be customized in diameter to meet specific requirements and can extend up to several tens of meters in length. Originally, geotextile tubes were employed in embankment‑construction projects.

　　Currently, thanks to the efforts of technical experts, it has been applied in fields such as environmental protection and agriculture. As research progresses, its range of applications is expected to expand further. Geotextile tube materials are typically made from high‑tenacity polypropylene and are usually black; depending on the specific product specifications, the standard basis weight is adjusted to 400 g/m².

　　Length is unlimited; width can be spliced multiple times. While width is not restricted, it directly affects the material requirements: the wider the width, the higher the required material strength. The filling height is fixed at two-thirds of the tube‑bag diameter. Customization is available to match the on-site grouting machine’s nozzle size, and additional admixtures may be added as needed to accelerate setting and enhance slurry–water separation.

　　Conventional natural dewatering at sludge disposal sites: This method is used to treat river and reservoir bottom sediments. It is technically straightforward but requires a large land footprint, making it a common approach in domestic sediment‑treatment projects—including the cleanup and treatment of Taihe Reservoir’s bottom sediments. However, its dewatering efficiency is very low, and this method for handling contaminated sediments still poses certain environmental and safety risks. Because the sediments in the storage yard are exposed and in direct contact with the surrounding environment, inadequate treatment of leachate can lead to secondary pollution of nearby water bodies.
