Product Description
Geotextile Tube is one of the most effective components that are most usually used in protective structure of waterproof erosion. Soft mattress is covered to the places where water flows to reduce the impact energy of water flow and protect soil particles from being flown away by water flow by means of its filtration function, thus, ensuring the stability of soil mass.

HOW TO USE GEOTEXTILE TUBE
Every geotextile tube project is unique. As such, general guidelines can be described, but each project requires consultation with a geotextile tube expert to identify the project's singular attributes and to design the sludge dewatering process accordingly. It is of utmost importance to place the geotextile tube on a level ground and before deploying, any barriers ,such as stone ,sundry , have to be removed as to prevent them from influencing the deploying effect. After the geotextile tube delivered to the site, secure it on ground with external steel pipe or timber pile to fix the position of geotube. Prepare the feeding equipment in advance, like cutter head and suction dredge (for dredged materials), feed pump (for sludge materials),which are to be used in the following operations.
Geotextile tube have a "shirt-sleeve" style filling port. Simply place the pump hose into the port and secure it with a hose clamp, tie-wire or duct tape. Once the pumping begins, clear, effluent water will drain from the tube through the small openings in the permeable geotextile fabric. Meanwhile, the sludge dewatering tube bottom will develop a filter cake quickly, so the water will decant mainly out of the sides and top of the tube gradually.
After a long-time cycle of repeated cycles of filling and dewatering, over 99% of solids are captured. Typically, the decanted water can be returned to waterways without additional treatment. If any erosion caused around the tube, deploy the sump pumps at the all four corners of the area to collect the effluent.
