Coastal Protection Geotextile Tubes
1. Resource recycling
It can effectively handle dredging sludge, industrial waste and other waste, achieve the goal of "turning waste into treasure", reduce landfill land occupation and environmental pollution.
2. Low cost
Compared to traditional sand and gravel filling or concrete structures, geotextile bag materials have lower costs and can be used on-site to reduce transportation costs.
3. Strong durability
Geotextiles have strong resistance to corrosion and biological erosion, and the stability of the consolidated structure is high, with a service life of several decades.
4. Eco friendly
During the construction process, there is no dust or noise pollution. After consolidation, vegetation can be planted on the surface to restore the ecological environment, making it suitable for ecological engineering construction.
Product Introduction:
Coastal Protection Geotextile Tubes are large tubular enclosure made of high-strength geotextile fabric (such as polypropylene) through special weaving or sewing processes. Its diameter and length can be flexibly customized according to engineering requirements, with a maximum length of tens of meters. The interior is filled with materials such as silt, sludge, and sludge, and after dehydration and consolidation, a stable structure is formed. It is widely used in fields such as water conservancy, environmental protection, and marine engineering.
characteristic
1. High strength and durability
The tensile strength reaches 45-200kN/m and can withstand high-pressure filling and long-term loads.
UV resistant, acid and alkali resistant (pH 2-13), suitable for harsh environments.
The suture site has high strength, low risk of bag bursting, and a service life of over 10 years.
2. Flexibility and customizability
The size can be adjusted as needed, and the diameter and length are flexible and adaptable to different site conditions.
Stackable transportation, saving space and reducing logistics costs.
3. Environmental Protection and Safety
Fully enclosed construction, no noise pollution, avoiding secondary pollution (such as silt leakage).
The dehydrated water can be reused and meets environmental standards.
4. Efficient dehydration and consolidation
The pores of geotextiles allow water to seep out while retaining solid particles, achieving mud water separation.
The volume of sludge can be reduced by over 90% within one month, and the solidified material can be used for backfilling or resource utilization.
