Plastic geogrids are polymer mesh materials with square or rectangular shapes formed by stretching, which can be divided into two types according to the different stretching directions during manufacturing: unidirectional stretching and biaxial stretching. It is a geotechnical material made from high-density polyethylene (HDPE) as the raw material, extruded into thin plates, punched into regular pore networks, and then stretched longitudinally.
Biaxially stretched plastic geogrids are suitable for reinforcing roadbeds, embankments, and slope protection, as well as for reinforcing tunnel walls! It can be used in parking lots, airports, docks, and other areas that require foundation reinforcement. It can replace metal mesh and be used as a top mesh in coal mines. It can also support the plants on the slope and stabilize the greening. Used on soil slopes to prevent soil erosion.
Biaxially stretched plastic geogrid is time-saving, labor-saving, and easy to construct, effectively reducing the number of repairs to your road surface. It can effectively prevent road collapse and cracking, and maintain the appearance of the ground. It can increase the bearing capacity of the roadbed and prolong the service life of the road surface.
The selection system and specific judgment of bidirectional plastic geogrids are very important, and attention should be paid to the design elements. During the current design process, it should be possible to consider these horizontal or vertical stretching. Many people currently have designs for these interlocking systems that can be applied to larger design foundations.
Nowadays, for the design of bidirectional plastic geogrids, many institutions need to be able to help with the overall design direction. During the design of these structures, they can continuously understand the interrelationships and contents through squeezing or punching, and also pay attention to the design reasons and problems of these quantities, which can achieve more two operations, It can also implement some system related content.
