Geotube absorbs off the sediments by means of a dredge pump and transports them to land in pressure hoses. The advantages of this type of sludge removal are manifold: no need to lower the water in the pond, so it can also be used in canals, gentle intervention in nature (no or little bank damage from hoses), and much more. The water escapes through the permeable fabric of the geotube seawall. After a few days, the contents can be removed like a solid and disposed of or used again. The geotube shoreline protection are filled with sludge by means of pumps through hoses. As the fluid escapes through the tissue, the solids are retained. The filling process is repeated until the hose is full. After geotube dewatering, the solids can be processed like a dry matter. Depending on the type, these substances can be transported away and disposed of or reused at low cost. Advantages and benefits of this geotube dewatering bags:
- No lowering of the water in the pond necessary
- Gentle intervention in nature, no bank damage
- Minimal cloudiness in the area of the dredge pump with geotube dredging
- Exact removal of the mud down to the bottom of the pond
- Intermediate mud transport without damaging the shore zone
- Lower disposal costs because of the lower volume of sludge
- Easier handling of the solid sludge during transport and disposal
Geotube: Textile Drainage Systems
If there is not enough space for a conditioned drying bed, we as Geobera often opts for drainage with a geotextile in geotube construction. A major advantage of textile drainage hoses is their easy scalability. If there is space, you can always use textile drainage hoses on top of or next to the other. Another advantage of these geotube specifications: textile drainage hoses make it possible to give a final, sustainable destination in the ground as storage or as a construction. As an example, the possible properties of the sludge, the need for flocculants and the production are illustrated above. Including the calculated quantities in all phases of the process.
We as Geobera which has been proceed many projects successfully in the USA, the UK, Russia, Bulgaria, Italy, France, Spain, Portugal, Greece and Malta, first carries out these calculations for each project and creates the so-called mass flow balance. This gives us a good insight into the desired dewatering process with the help of geotubes for erosion control. We as one of the most important geotube manufacturers use the data to use the software to calculate the optimal dosage of the flocculant for the duration of the entire project. At this point you will soon have the opportunity to create the mass flow balance yourself by entering the required data. On the basis of our expertise, we work efficiently and effectively and thus save costs for you if you know geotube costs.
The Procedure of Geotube and Geotube Installation Cost
What can be seen in the drawing? The dredging sludge is pumped up on site using a dredging pump, with a lot of water being carried along. The sludge is pumped into textile drainage hoses via an excavator line. During the pumping process, geotube breakwater constantly measures the dry matter content and the throughput of the sludge. In the process computer, into which the data of the mass flow balance were entered, the dosage of the flocculent is continuously calculated on the basis of the measurements. This takes place a little later in the line, possibly with the addition of some mixing water. A mixer in the line then mixes the flocculent into the sludge. Finally, the sludge mixed with flocculent gets into the textile drainage hoses, in which the sludge particles quickly settle. The geotextile according to geotube sizes acts as a filter for the mud flakes so that the emerging water is absolutely clear. This clear water is fed back into the original surface water.
