Introduction

?

The High Strength Woven? geotextile is a kind of new building materials. According to the manufacturing methods are divided into: There are two types of nonwoven geotextiles and geotextile. General engineering is the use of nonwoven geotextile,The High Strength Woven? geotextile has the functions of waterproof, filtration, drainage, isolation, reinforcement, protection, sealing, compared with the masonry and concrete anti-seepage effect with conventional, low investment, simple construction process, short construction period, good anti-seepage effect, channel the effective utilization coefficient etc.

Applications:

?

(1) artificial filling foundation movement of ground water.

(2) gravel filter layer surrounding the periphery of the drain pipe drain.

(3) in water conservancy projects wells, relief wells or inclined pipe filter.

(4) for retaining wall backfill reinforcement, or for anchored retaining wall panel.

(5) reinforced flexible pavements, crack repair roads, prevent the reflection cracks of pavement.

(6) in ternal vertical or horizontal drainage, dissipation of pore water pressure in soil.

(7) water impermeable geomembrane dam or embankment in the lower part of the back or the concrete.

(8) the isolation layer between the road ballast and subgrade, isolation layer or between the embankment and soft foundation.

(9) the isolation layer soil between highway, airport, railway ballast and artificial rockfill and soil fabric.
