Uses, Construction, and Applicable Scenarios of Sichuan Steel-Plastic Geogrids
Release date:
2020-10-14
1. Sichuan Zigong Steel-Plastic Geogrid Uses
It can be used in a wide range of civil engineering applications, including highways, railways, embankments, bridge abutments, temporary construction roads, docks, shoreline protection structures, flood control levees, dams, tidal flat management, cargo terminals, waste disposal sites, airports, sports fields, environmental protection buildings, soft ground stabilization, retaining walls, slope protection systems, and pavement reinforcement to enhance durability against adverse conditions.
Sichuan Zigong Steel-Plastic Geogrid The specific benefits:
Separation: Separate the subgrade soil from the ballast to effectively prevent dirt from entering the ballast and causing the track to sink into the foundation.
Reinforcement: Ensures that the load transmitted by the ballast is evenly distributed across the track bed, enhancing the ballast's ability to withstand loads at its top.
Drainage: Utilizing capillary action to remove water from the roadbed, strengthening the subgrade, enhancing the road's load-bearing capacity, and minimizing track settlement.
2. Sichuan Zigong Steel-Plastic Geogrid The construction method
(1) First, mark out the embankment slope lines. To ensure the required embankment width, add 0.5 meters on each side. After leveling the dried-up subgrade soil, compact it twice using a 25-ton vibratory roller in static mode, followed by four passes with a 50-ton vibrating roller. Any uneven areas should then be manually leveled to achieve a smooth finish.
(2) Lay a 0.3-meter-thick layer of medium (or coarse) sand, then manually and mechanically level it thoroughly. Afterward, compact the surface twice using a 25-ton vibratory roller in static mode.
(3) Laying out Sichuan Zigong Steel-Plastic Geogrid When laying the geogrid, the underlying surface should be smooth and densely compacted. Generally, the geogrid should be spread flat, fully straightened, and must not overlap, curl, or twist. The adjacent sheets of geogrid need to be lapped by 0.2 meters, with 8-gauge wire threaded through the overlapping sections every 1 meter along the transverse direction of the subgrade. Additionally, the laid geogrid should be secured to the ground at intervals of 1.5 to 2 meters using U-shaped nails.
(4) Ground Floor Sichuan Zigong Steel-Plastic Geogrid After laying the material, begin filling with a 0.2-meter-thick layer of medium (coarse) sand on the second level. The method is as follows: Transport the sand to the site by truck and unload it onto one side of the subgrade. Then, use a bulldozer to push the sand forward, first compacting the area within 2 meters on both sides of the subgrade to a depth of 0.1 meter. Next, fold up the geogrid layer, place another 0.1-meter layer of medium (coarse) sand on top, and ensure no lateral movement—neither from the sides toward the center nor vice versa. Additionally, prohibit any machinery from operating directly over the geogrid before the medium (coarse) sand has been fully laid. This approach guarantees that the geogrid remains flat, without buckling or wrinkling. Once the second layer of medium (coarse) sand is evenly spread and leveled, conduct a precise horizontal survey to avoid uneven fill thickness. Finally, after confirming the correct elevation, roll the surface twice using a 25-ton vibratory roller in static mode.
(5) Second Floor Sichuan Zigong Steel-Plastic Geogrid The construction method is the same as for the previous layer: first, backfill with 0.3 meters of medium (or coarse) sand, using the same layer-by-layer filling technique. After compacting twice with a 25-ton static 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 connect them using the same method. Then, proceed with earthwork operations by installing the geogrids for slope protection. Importantly, measure the exact placement lines for each layer, ensuring that after final slope trimming, the geogrids are embedded at least 0.10 meters into the slope on both sides.
(7) Slope Sichuan Zigong Steel-Plastic Geogrid Every two layers of soil—each 0.8 meters thick—require the simultaneous placement of a geogrid layer on both sides, and this process continues sequentially until the geogrid reaches just below the shoulder surface.
(8) After the embankment 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 the embankment also includes a 1.5% settlement allowance.
3. Sichuan Zigong Steel-Plastic Geogrid Applicable scenarios
Generally used when the fill height exceeds 4 meters in soft ground treatment projects.
It is used during soft ground treatment when the embankment height is between 3 and 4 meters, or at the junctions between roads and bridges, to prevent uneven settlement. Additionally, when widening an existing road, a layer is added at the joint between the new and old subgrades to prevent longitudinal cracks from forming.
Soft ground treatment for low embankment and shallow excavation sections, as well as for fill areas less than 2 meters deep; and reinforcement of subgrades in problematic sections to prevent cracking.
