3 The role of short-filament geotextile in the project
1, reinforcement, reinforcement: reinforcement is generally divided into macro reinforcement and micro reinforcement, and the reinforcement of geotextile belongs to the field of macro reinforcement, short filament geotextile although also has a reinforcing function due to the mechanical function of the goal being relatively small, so for reinforcement has certain limitations.
2, filtration and drainage: short filament geotextile in the filtration and drainage is mainly to replace the traditional material gravel layer, geotextile drainage and geotextile thickness is proportional to the connection, generally speaking, the thicker the thickness, then the geotextile drainage ability is better.
3, barrier: short filament geotextile can separate two materials with different grain sizes to ensure the stability of the structure, but the load that short filament geotextile can accept as a barrier layer cannot be too large.
4, protection: short silk geotextile is still used in more protection projects, such as protection on the slope, urban greening, to prevent the occurrence of road cracks, etc.
