Geotextile tubes are typically made of high-tenacity polypropylene or woven fabric, with the specific material selected based on project requirements; they are generally black in color. While standard material weight is 400 g/m², specifications can be adjusted; lengths are unlimited, and widths can be extended by stitching multiple panels together—though width directly impacts strength requirements (greater widths demand higher material strength). The filling height is generally set at two-thirds of the tube's diameter. Customization is available to match the diameter of the site's grouting equipment, and chemical additives can be incorporated based on actual conditions to accelerate solidification and the separation of solids from liquids.
Why Use Geotextile Tubes for Dredging and Solidification?
1. **Traditional Natural Dewatering in Sediment Disposal Areas:** This method for treating river and reservoir sediment is technically simple but requires a large land footprint; it is a common approach in domestic sediment treatment projects (including the cleanup and treatment of Taihu Lake sediment). However, this dewatering method is highly inefficient, and treating contaminated sediment in disposal areas poses certain environmental and safety risks. Because the sediment in the disposal area remains exposed and in direct contact with the surrounding environment, failure to properly treat residual water can lead to secondary pollution of nearby water bodies.
2. **Mechanical Dewatering Methods:** While effective at dewatering sediment contaminated with organic matter and heavy metals, these methods have drawbacks: high initial equipment investment, significant energy consumption, the need for dedicated processing facilities, and processing capacities that often fail to meet the tight schedules required for on-site river and reservoir sediment remediation.
3. **Geotextile Tube Dredging:** **Convenience:** Geotextile tube diameters and lengths can be adjusted as needed; they are highly adaptable, stackable, and easy to transport. **Environmental Friendliness:** Operations are fully enclosed, generating minimal noise and posing little risk of secondary pollution. **High Efficiency:** Capable of handling required wastewater and sludge volumes; the number of tubes used can be scaled up or down based on pump flow rates. **Effective Volume Reduction:** Sludge volume can be reduced by over 90% within a month, simplifying subsequent removal and disposal. **Broad Applicability:** Suitable for a wide range of wastewater treatment and sludge dewatering projects, regardless of scale.

Step 1: Sludge Processing – Slurry collection → Debris separation tank → Sludge tank. These steps are implemented selectively based on specific project site requirements.
Step 2: Geotextile Tube Laying – Prefabricated tubes are transported to the site and laid out according to the staked-out positions. To prevent rolling, sliding, or displacement during filling and to ensure accurate positioning, the tubes must be anchored after laying. Bottom-layer tubes are anchored by driving steel anchor pipes alongside them and connecting the tubes' anchor rings to the pipes. Once the bottom layer is filled, upper-layer tubes are anchored by tying their side pull-rings to the filled bottom tubes using geotextile straps, creating an integrated structure.
Step 3: Reagent Dissolution – Field testing of the sludge determines whether one or two types of reagents are required. The clean water used for this process is recycled from the effluent discharged by the tubes.
Step 4: Dewatering – The geotextile fabric forming the tube features microscopic pores that retain solid particles while allowing water to drain out. This effectively reduces the volume of the contained material, enabling repeated filling cycles until the maximum allowable height for the material is reached; the discharged water can be reused.
Step 5: Consolidation – Following multiple filling and dewatering cycles, the fine particles remaining inside the tube gradually consolidate due to the drying process.
