High Tenacity 13.7m*20m PP Geotextile Tubes For Dewatering Process
Geotextile tubes are made by PP woven fabric in a variety of sizes
and lengths. They are in extra wide sizes with greater load
distribution to resist punching and protect the embankment and foundation. Geotextile tubes are not only used
to form shoreline structure including form temporary breakwaters,
headlands, revetment on sand beach, also used in environment protection, like fill in the
pollution silt, they let the waters out and retain the solid articles.
A large volume of water may be released from the tubes during the
operation and can cause erosion around the tube. As such, the rate
at which the water is decanted must be monitored. 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.
Therefore, it may be beneficial to cover the deployment area in
plastic such as Visqueen and deploy sump pumps at all four corners
of the dewatering area to collect the effluent. The effluent can
then be returned creating a “closed-loop” system. If the tube will
be exposed to external moving water, a scour apron with an attached
anchor tube may be required.
Geotextile tubes are manufactured from high strength polypropylene geotextiles and
are permeable and resistant to ultra-violet light and the stresses
associated with filling and placement including: abrasion, tearing,
puncturing and flattening. Geotextile tubes are made to the desired diameter from standard
width geotextiles. The length of the sludge dewatering tube is
limited only by its weight. Filling ports are regularly spaced
along the length of the tube at appropriate intervals.
In most cases, the geotextile tube will be delivered to the site on
a skid, rolled up on a pipe core. Alternate packaging, such as
accordion folding, may be used. Although sturdy, geotextile tubes
can be damaged during loading, off-loading and shipping. It is very
important that any shipment be thoroughly inspected for rips and
punctures before signing any shipping documents. In the case of
damage, all problems should be noted on the shipping documents and
the delivery refused. Once a damaged tube has been received and the
shipping documents signed, it is nearly impossible to seek remedy
from the shipping company.
How do I use geotextile tubes?
o Inspect geotextile tube for shipping damage
o Unroll tube flat on level ground
o Make sure tube is constrained and secured
o Place tube on an impermeable geomembrane if erosion is a concern
o Connect and secure pump hose to filling port sleeve
o Monitor geotextile tube during filling for possible ruptures
o Utilized repeated cycles of filling and dewatering
o Deposit filled tube properly in a landfill or cut open and remove
Every geotextile tube project is unique. As such, only 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.
Proper site preparation is of utmost importance. Geotextile tubes
can roll, especially during filling. It is important that they are
constrained and placed on level ground. Once properly deployed and
secured in place, the geotextile tube is hydraulically filled with
dredged materials using a cutter head and suction dredge or with
sludge materials using a feed pump.
Geotextile tubes have a “shirt-sleeve” style filling port. Simply place the hose
into the port and secure it with a hose clamp, tie-wire or duct
Once the pumping begins, clear, effluent water will drain from the
geotextile tube through the small openings in the permeable
geotextile fabric. Often the decanted water can be reused or
returned to waterways without additional treatment. During pumping,
the elevation or height of the tube needs to be monitored to
- High tensile strength (up to 200KN)
- High UV resistance (90%/500h)
- High sewing strength (more than 60%)
- High resistance to acid and alkali corrosion resistance
