Specific Applications of Zhejiang Fiberglass Geogrids in Reinforcing High Embankment Slopes
Release date:
2020-10-20
(8) After the subgrade is filled, 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 1.5% settlement allowance. Featuring advantages such as lightweight design, excellent overall continuity, high tensile strength, corrosion resistance, superior resistance to microbial erosion, and ease of construction, it is now widely used in highway projects—for applications like reinforcing high embankment slopes, among other areas. Compared to traditional reinforcement methods like retaining walls and facing walls, Zhejiang Quzhou fiberglass geogrids offer the benefits of simple and rapid installation, along with lower costs, making them a promising solution with broad application potential.
Let's get acquainted first. (8) After the subgrade is filled, 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 1.5% settlement allowance. The construction method:
(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 with a 50-ton vibratory roller. Any uneven areas should 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 thoroughly. 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 out flat, pulled taut, and laid without overlapping, curling, or twisting. The adjacent sheets must be lapped by 0.2 meters, with #8 wire threaded through the overlap every 1 meter along the transverse direction of the subgrade. Additionally, secure each laid geogrid to the ground at intervals of 1.5 to 2 meters using U-shaped nails.
(4) After the first layer of geogrid is laid, begin filling with a 0.2-meter-thick layer of medium (coarse) sand. The method is as follows: Transport the sand to the site by truck and dump it on 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 first-layer geogrid and continue backfilling with another 0.1 meter of medium (coarse) sand. Avoid filling or advancing the material from the sides toward the center, and strictly prohibit any machinery from operating directly over the geogrid before it’s fully covered with medium (coarse) sand. This ensures the geogrid remains flat, without bulging or wrinkling. Once the second layer of medium (coarse) sand is evenly spread, perform a precise horizontal survey to prevent 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 with 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 of di, 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 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) For each two layers of soil compacted—equivalent to a thickness of 0.8 meters—a layer of geogrid must be simultaneously placed on both sides of the slope. This process is repeated until the geogrid reaches just below the shoulder surface.
(8) After the subgrade is filled, 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预留 1.5% settlement allowance.
(8) After the subgrade is filled, 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 1.5% settlement allowance. Specific applications in the high embankment slope reinforcement project are as follows:
1. Lay out according to the designed width on the leveled subgrade. (8) After the subgrade is filled, 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 1.5% settlement allowance. When laying, ensure the material is straightened and smooth. During installation, orient the higher-strength direction perpendicular to the embankment’s axis. Secure overlapping sections with U-shaped nails, using at least two nails at each overlap point.
2, (8) After the subgrade is filled, 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 1.5% settlement allowance. When the tensile stress in the crack increases and exceeds the tensile strength of the anti-crack layer, this structure represents an integrated, organic application of several current measures used to prevent cracking on highways. The surface layer then begins to bear the tensile stress transmitted by the anti-crack bars.
3. The crack-resistant polymer forms a seamless waterproof layer that effectively breaks up water on the road surface, (8) After the subgrade is filled, 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 1.5% settlement allowance. It is a major geosynthetic material, compared to other geosynthetics.
