The geotextile has a certain amount of deformation, and the stress transfer caused by the concave and convex defects of the bottom cushion is distributed quickly and has a strong strain capacity. The pore pressure and floating force on the contact surface between the geotextile and the soil are easy to dissipate. Geotextile has a certain thermal insulation effect, which reduces the damage of soil frost heaving to geomembrane and geotextile, thereby reducing soil deformation. The geotextile is buried and laid, which has excellent anti-aging properties and reduces the maintenance and maintenance of the project.
Geotextile laying and construction is simple, reducing transportation volume, reducing project cost and shortening construction period. Geotextiles use geotextiles instead of granular materials as the protective layer of geotextiles to protect the anti-seepage layer of geotextiles from damage, reduce the grading requirements of the particle size of the cushion, and play a role in drainage. The composite geomembrane has a large friction coefficient, which can prevent the sliding of the covering layer. It has more protective layers than the simple geotextile. The non-woven fabric in the geotextile has a larger friction coefficient. The geotextile can increase the slope ratio and reduce the floor space. . The mechanical strength of geotextile is high in tensile, tearing, bursting and puncture.
Greening the ecological environment is ordered by the society, and geotextiles have attracted public attention in this project. At the same time, the ecological slope protection engineering system is to use soft materials to build flexible slopes and retaining walls, and complete the plane greening of reservoirs and slope banks. , the real performance of the project to create an ecological green project that is safe, energy-saving, survivable, and will take a deep breath in the southern district. The project does not require hard materials such as steel frame, lime, and stone with high energy consumption and high pollution, and can also be used for the repair of vertical or near-vertical steep rock strata slopes, drainage ditches and reservoirs. What is the principle of using geotextiles for greening on three-dimensional, slopes and high slopes?
First, the geotextile allows moisture to convect each other in the bag and the soil of the bag. This moisture is the moisture needed for vegetation to grow, not to mention that it will never cause fruit or soil loss due to rain or watering. Second, geotextiles require an actual seeding block for green plants. Water permeable and impervious to soil, grass can grow from the surface or grow on the surface, it is very good for vegetation, the root system of vegetation can develop calmly between bags and bags, and the root system firmly connects each composite geomembrane into one. into a stable and permanent ecological slope.
