Today, I will introduce the ice pressure of the high quality long fibre filament needle punched geotextile. I hope everyone can have a deeper understanding of it:

Now taking the Dixie Delta as an example, the ice pressure observation at the test site of the geotechnical fabric filter layer, the chemical fiber mold bag, the concrete rib beam grid filled with dry stone and the rib beam concrete slab Engineering prototype observation, draws the conclusion: regardless of geotextile fabric filter layer, geotextile bottom protection body. Or the chemical fiber mold bag has no damage due to frost heave or ice pressure.

In the water conservancy project, there is a lot of need to remove the water in the soil. For example, the location of the high quality long fibre filament needle punched geotextile immersion line is reduced in the dam project to reduce the seepage force, and the back wall of the retaining wall is drained to reduce the water pressure and improve the stability of the wall. Drainage, reduce pore pressure, prevent soil slope instability, tunnel and corridor drainage, to reduce water seepage pressure, soft soil foundation drainage, to accelerate soil consolidation, improve foundation bearing capacity and so on.

The traditional drainage materials are mostly made of strong permeable granular materials. When the filament geotextiles are used as drainage, they also act as a filter, and at the same time, they do not fail due to the consolidation and deformation of the soil. The filament geotextile has a simple construction and shortens the construction period. Saving engineering costs and other advantages.
