1. Uniaxial plastic geogrid is used for roadbed and pavement.
First of all, the foundation bed should be excavated and sand cushion should be set up (the height difference is not more than 10 cm). Then roll it into a platform and lay a grille.
When laying the uniaxial geogrid, the longitudinal direction should be consistent with the main direction of the force. In addition, the longitudinal lap joint is 15-20 cm and the lateral lap joint is 10 cm. And the lap is tied with plastic tape. Then on the laid geogrid, every 1.5-2m with U-nails fixed to the ground.
Finally, the geogrids should be backfilled in time and the layers of geogrids should be visualized.
2. Uniaxial plastic geogrid is used for reinforced retaining wall
That's all for today. Tomorrow we will continue to explain the construction method of uniaxial plastic grille used in the reinforced retaining wall. To be continued……
