Geotube construction is a method of handling mud, sand, and other materials by pumping them into geotextile tubes, allowing water to drain through the filter fabric and form a solid, stable mass of material. The process includes laying and positioning the tubes, installing the pumping system, pumping the materials, densifying and stabilizing the structure, and completing the project. This method is commonly used in coastal works, sea dykes, land reclamation, and land reclamation, with the advantages of reasonable cost, quick construction, and environmental friendliness.
