Geo-tubes are one of the representatives of a product line of stich circular geosynthetic coverings, as well as geo-containers. They differ from each other in a number of parameters, among which are: pore size, length and width, strength, material used in the production process, and so on.
Geo-tubes for hydraulic engineering and sludge dewatering that are in the assortments range of the MIAKOM company have enhanced resistance to destructive adverse external factors (like moisture, ultraviolet, microorganisms, oxidation and other), that determines the long term of their working life and economic benefits from it.
Geo-tubes deal with a wide variety of challenges.
Two main application areas are:
- hydraulic engineering;
- sludge dewatering.
Required geometrical parameters, technical properties, raw material for geotube production (geocomposite, polypropylene, polyester) are determined by peculiarities of each project, for the implementation of which they are ordered. We take into account all the required parameters in the manufacturing process of geo-tubes and geo-containers so that a client could receive a product that meets his needs.
Geo-tubes in hydraulic engineering
berthing structures constriction;
prevention from erosion and washing out of a coastline;
constriction of water areas protected from negative exposure of waves;
storage of excavation soil that is unsuitable for use;
constriction of hydrotechnical spur dikes, moles, breakwaters and cutwaters;
The coastline is constantly susceptible to the negative effects of water bodies. Erosion processes are a widespread problem, since it provokes a change in the contours of the coastline. Where necessary, shore protection works are carried out. And today, preference is given to efficient technologies and environmentally friendly materials.
Due to new achievements in this direction, erosion processes, in many cases, can be completely stopped, while in others they can be significantly slowed down!
Geosynthetic tubes are a unique combination of durable geofabric and optimal structure (special funnels are placed on it). The latter are necessary to fill the geotube with a water-sand mixture by means of pumping equipment. The widest range of different geotechnical tasks allows such geo-tubes to be applied, having a highly permeable covering that allows water to pass through but retains sand and other solid particles larger than the tube’s pore diameter.
Geo-tubes in sludge dewatering
wastewater treatment of various origins: industrial, municipal, storm and others;
treatment of drilling wastes from gas and oil wells;
cleaning of silt detention ponds, utility sediments, mud settling sump;
dehydration and storage of manure in agriculture;
fly ash removal at garbage disposal plants, thermal power plants and thermal power stations;
increasing the productivity of gold mining;
purification of sediment from sludge and various bottom sediments;
industrial production of sapropel;
dewatering sludge of industrial waste;
treatment of flooded radioactive waste and those that are highly toxic;
providing various technological and production processes, from pulp and paper mills to the production of Portland cement and other binders.
The technology of sludge dewatering using geo-tubes is of great interest around the world for two simple reasons: economic efficiency and ease of installation, operation, maintenance.
A prepared in advance area, pumping equipment, flocculant dispenser - that's all that is needed to implement this technology of sludge dewatering, except, in fact, the geosynthetic tubes themselves.
Thanks to geo-tubes, colossal material and labor resources can be saved. High results can never be achieved using traditional methods of mechanical sludge dewatering.
Application of geo-containers
Geo-containers under MIATUBE brand mark are geosynthetic sleeves with a capacity of 0.01 to 5 and more cubic meters that are filled directly at the place of work with industrial material, gravel, small gravel, sandy loam, sand or other granular material.
Geo-containers are manufactured as single-layered or double-layered.For single-layer products, the initial is a geofabric made of polypropylene or polyester, the strength of which is determined by calculation based on current loads and exposure. For two-layer (geocomposite) geo-containers, the second layer is a non-woven needle-punched geotextile (manufactured under the MIAKOM IP trademark), which performs protective and / or drainage functions.
