2. After securing the grating at the ends, slowly pull and lay the grating forward using a paving machine or manual labor. For every 10-meter section laid, straighten it manually once—continue this process until one roll of grating is fully铺完, then proceed to铺下一 roll, following the same procedure as before. Primarily used in areas such as soft ground stabilization for highways, railways, bridge abutments, approach roads, docks, dams, and spoil grounds, as well as in retaining wall construction and pavement crack-repair projects. 2. After securing the grating at the ends, slowly pull and lay the grating forward using a paving machine or manual labor. For every 10-meter section laid, straighten it manually once—continue this process until one roll of grating is fully铺完, then proceed to铺下一 roll, following the same procedure as before. The high-density polyethylene used ensures that the material remains unaffected by acidic, alkaline, or saline solutions, as well as oils, at room temperature—and it won’t be attacked by water or microorganisms. Additionally, the polymer’s superior properties provide ample resistance against aging caused by ultraviolet radiation. 2.

The engineering function:

1. High strength, minimal creep, and excellent adaptability to various soil conditions—these features fully meet the demands of tall retaining walls used in high-grade highways.

2. Effectively enhances the interlocking and interlocking action of the reinforced bearing surface, significantly boosting the foundation's load-bearing capacity, efficiently restraining lateral soil displacement, and improving the overall stability of the foundation.

3. Compared to traditional gratings, it boasts enhanced strength, superior load-bearing capacity, excellent corrosion resistance, outstanding aging resistance, a high coefficient of friction, uniformly sized openings, ease of installation, and an exceptionally long service life.

4. More suitable for deep-sea operations and embankment reinforcement, this solution fundamentally addresses the technical challenges—such as low strength, poor corrosion resistance, and short service life—that have traditionally plagued stone cages made from other materials due to prolonged exposure to seawater erosion.

5. Effectively prevents construction damage caused by machinery running over or otherwise damaging materials during the construction process.

Specific construction method:

1. 2. After securing the grating at the ends, slowly pull and lay the grating forward using a paving machine or manual labor. For every 10-meter section laid, straighten it manually once—continue this process until one roll of grating is fully铺完, then proceed to铺下一 roll, following the same procedure as before. The paving surface should be relatively smooth. After the paving layer has passed inspection, to prevent longitudinal distortion, first mark white lines or hang strings across the width of the layer before starting the actual laying process. Then, secure the edges of the geogrid using U-shaped nails—installing four nails per meter of width at evenly spaced intervals.

2. After securing the grating at the ends, slowly pull and lay the grating forward using a paving machine or manual labor. For every 10-meter section laid, straighten it manually once—continue this process until one roll of grating is fully铺完, then proceed to铺下一 roll, following the same procedure as before.

3. Laying Process: Use the roll length as the segment for each laying section. After fully covering the grid within a segment, perform a comprehensive quality check before proceeding to lay the next section.

2. After securing the grating at the ends, slowly pull and lay the grating forward using a paving machine or manual labor. For every 10-meter section laid, straighten it manually once—continue this process until one roll of grating is fully铺完, then proceed to铺下一 roll, following the same procedure as before. When subjected to stress, the longitudinal and transverse ribs work together synergistically, preventing cracking or damage at the joints. In practical engineering applications, after the backfill material has been properly compacted, it remains protected from UV radiation and oxygen exposure, thereby fully meeting the durability requirements for long-term construction projects.
