After highly tensile orientation, the molecular structure of geogrid has the characteristics of high strength and low extension, and its elastic modulus is close to the level of low-carbon steel. Therefore, it can be used as reinforcement and reinforcement in civil engineering. At present, it has been widely used in the construction of expressway, railway subgrade, reinforced embankment and hydraulic engineering. However, without precedent, plastic geogrids should be used for the treatment of flood control embankments in areas with poor geological conditions, and successfully applied to practical engineering problems.

Plastic geogrid data was used to process the foundation of the embankment, and the height of the embankment reached over 10m, without any settlement, landslide or other phenomena. The foundation of the dam near the section with similar terrain was treated with dredging, but there were still landslides, and the tendency of landslides was significant after the embankment filling height exceeded 4m. From this, it can be seen that the use of plastic geogrids for embankment foundation treatment can significantly avoid settlement and landslide phenomena, effectively improve the bearing capacity of the foundation, and the embankment has a good anti-seepage effect without any leakage phenomenon.

plastic geogridNot only is it suitable for the construction of highways, railway embankments, reinforced earth embankments, and water conservancy projects, but it can also be used for embankment foundation treatment when building flood control embankments in lake areas with poor geological conditions, and then deal with practical engineering problems. It has advantages that cannot be replaced by other materials, and is a new type of data that is worth promoting and applying in the treatment of embankment foundations. It can be vigorously promoted and applied in future lake area governance projects.

Compared with similar projects without the use of plastic geogrids, its construction cost can be saved by 40%, the construction period can be shortened by 50%, and the economic and social benefits are significant. The construction area of plastic geogrid has significantly improved the bearing capacity of the foundation, with a straight displacement of ≤ 40cm for the settlement of the embankment, within the normal deformation scale. The use of geogrid data to process large embankments can prevent collapse and slip slopes.
