Description
Introduction
Dewatering-tube is a kind of pipe used for drainage, precipitation and lowering of groundwater level. Its main function is to discharge moisture from the soil or inside the structure, prevent water pressure accumulation, and enhance the stability and safety of the structure. It is widely used in foundation pit support, slope protection, roads, railways, tunnels, water conservancy and other projects.
Advantages
1. High tensile strength The tensile strength of this type of dewatering pipe in both the longitudinal and transverse directions reaches 45 KN/m, which can effectively resist the soil side pressure and construction stress during use. In engineering applications, this tensile property helps to maintain the stability of the overall structure of the pipe and reduce the risk of breakage or damage caused by uneven force. It is particularly suitable for use in geological environments with high pressure.
2. Good ductility The product has good ductility, with a longitudinal elongation of 20% and a transverse elongation (CD direction) of 18%. This ductility allows the pipe to maintain its shape intact and not easily tear when the foundation settles locally or the force changes slightly, thereby improving its applicability and safety under different construction conditions.
3. Dense material The cone diameter of the dewatering pipe is 9mm, indicating that it has high puncture resistance and material density, which helps prevent external sharp objects or soil particles from damaging the pipe. In addition, its wear resistance is 70%, which means that it can maintain stable performance during long-term contact with soil and water flow, reducing the problem of leakage or decreased drainage efficiency caused by wear of pipes.
4. Strong UV tolerance In the UV aging test, the product can still maintain 90% of its UV protection performance after 500 hours of exposure. This performance makes it less prone to aging during outdoor storage or construction, suitable for long-term exposure environments, reduces the problem of shortened service life due to material aging, and provides greater flexibility for projects with long construction periods or limited storage conditions.
Common product models
LK-Tube 50-50
Most urban sewage treatment plants store the generated sludge in ponds for further anaerobic processes. Over time, these ponds will become filled with sludge and require cleaning. LK-Tube 50-50 (sludge dewatering pipe) is specifically designed for this purpose.
√Small size geobags
√Min tensile strength
√Highest flow rate
LK-Tube 70-95
These geotextile bags are inert to biodegradation and resistant to alkali and acid encountered. It is widely used in environmental dewatering applications, such as dewatering of urban waste, mine sludge, and polluted sediments.
√Tailor size you want
√High dewatering efficiency
√Cost effective
LK-Tube 120-120
TUBE 120-120 is a weather resistant geotextile pipe filled with mortar to form artificial coastal structures such as revetments, breakwaters, and embankments. They align with the coastline to reduce wave energy and prevent coastal erosion.
√Custom fabricated with high seam strength
√Competitve price because of good management
√Small orders are available with fast delivery
LK-Tube 175-175
It is a weather resistant geotextile pipe filled with mortar to form artificial coastal structures such as revetments, breakwaters, and embankments. It has the required durability and can remain intact throughout the design life of the device.
√Strong enough to protect things behand
√Stack to form strong structure
√Easy operation
LK-Tube 200-200
LK-TUBE 200-200 is even stronger than LK-Tube 175-175. It is a weather resistant geotextile pipe filled with mortar, forming artificial coastal structures such as revetments, breakwaters, and dams. It has the required durability and can remain intact throughout the design life of the device.
√Strong enough to protect things behand
√Stack to form strong structure
√Easy operation
