How can Guangxi's biaxially oriented plastic geogrids achieve the best construction performance on-site?
Release date:
2020-10-26
Guangxi Yulin Bidirectional Biaxial Plastic Geogrid It is produced by extruding, sheeting, and punching a polymer-based material, followed by longitudinal and transverse stretching. This material exhibits exceptional tensile strength in both the longitudinal and transverse directions. Such a structural design not only effectively distributes and transfers loads within the soil but also creates an ideal interlocking system, making it perfectly suited for large-scale, long-term reinforcement of foundation systems designed to withstand heavy loads.
1. Guangxi Yulin Bidirectional Biaxial Plastic Geogrid Product features:
1. Enhance the load-bearing capacity of the road (or ground) foundation, extending its service life;
2. Prevent road (or ground) surfaces from collapsing or cracking, ensuring a neat and attractive appearance;
3. Easy to install, saving time and effort, shortening the construction period, and reducing maintenance costs;
4. Prevent cracks from forming in the culvert;
5. Reinforce soil slopes to prevent water and soil erosion;
6. Reduce the thickness of the subbase to minimize costs;
7. Stabilizing and greening the environment by supporting slope vegetation with grass mats;
8. Can replace metal mesh and is used for temporary roof support in coal mine shafts;
2. Guangxi Yulin Bidirectional Biaxial Plastic Geogrid Product applications:
Guangxi Yulin Bidirectional Biaxial Plastic Geogrid Used for reinforcing various types of dams and roadbeds, protecting slopes, strengthening tunnel linings, and providing long-term load-bearing support for foundations in large airports, parking lots, port cargo areas, and more.
Three Guangxi Yulin Bidirectional Biaxial Plastic Geogrid Construction:
(1) First, accurately mark the embankment slope lines. To ensure the required embankment width, add an extra 0.5 meters on each side. After leveling the dried-out subgrade soil, compact it twice using a 25-ton vibratory roller in static mode, followed by four passes of compaction with a 50-ton vibratory roller. Any uneven areas should then be manually leveled to achieve a smooth surface.
(2) Lay a 0.3-meter-thick layer of medium (coarse) sand, then manually and mechanically level it evenly. Afterward, compact the surface twice using a 25-ton vibratory roller in static mode.
(3) Lay the geogrids, ensuring that the bottom surface remains smooth and compact during installation. Generally, the geogrids should be spread flat, straightened, and laid without overlapping, curling, or twisting. The adjacent sheets must overlap by 0.2 meters, with 8-gauge wire threaded through every 1 meter along the transverse direction of the subgrade at the overlap points. Additionally, secure the laid geogrids to the ground at intervals of 1.5 to 2 meters using U-shaped nails.
(4) After the first layer of geogrid is laid, proceed with backfilling the second layer—0.2 meters of medium (or coarse) sand—using the following method: Transport the sand to the site by truck and dump it on one side of the subgrade. Then, use a bulldozer to push the material forward. First, compact 0.1 meters of sand within the 2-meter-wide areas on both sides of the subgrade. Next, fold up the edges of the previously laid geogrid, add another 0.1 meter of medium (or coarse) sand, and ensure no material is pushed inward from the sides toward the center. Additionally, prohibit any machinery from operating directly over the geogrid before it’s fully covered with medium (or coarse) sand. This approach guarantees that the geogrid remains flat, without bulging or wrinkling. Once the second layer of medium (or coarse) sand is evenly spread and leveled, perform a precise horizontal survey to avoid uneven compaction thickness. Finally, after confirming the surface is properly leveled, roll the area twice using a 25-ton vibratory roller in static mode.
(5) The construction method for the second layer of geogrid is identical to that of the first layer. Finally, backfill 0.3 meters of medium (or coarse) sand, using the same filling technique as the first layer. After two passes of static compaction with a 25-ton roller, the subgrade reinforcement at the base will be fully completed.
(6) After the coarse sand has been properly compacted on the third layer, lay two layers of geogrids along the longitudinal direction of the slope, one on each side. Ensure an overlap of 0.16 meters and securely join them using the same method. Then, proceed with earthwork operations, installing the geogrids for slope protection. Importantly, measure the exact placement line of each layer, ensuring that after final slope trimming, the geogrid is embedded at least 0.10 meters into the slope on both sides.
(7) For every two layers of soil compacted—each 0.8 meters thick—geogrids must be simultaneously laid on both sides of the slope. This process is repeated until the geogrids reach just below the road shoulder surface.
(8) After the subgrade filling is completed, promptly carry out slope trimming and install dry-stacked stone protection at the toe of the slope. In addition to widening each side by 0.3 meters, this section of subgrade also includes a reserved settlement allowance of 1.5 percent.
