Construction method of steel plastic geogrid:

1. The laying surface of geogrid should be relatively flat. After the laying layer is accepted as qualified, in order to prevent longitudinal deviation, white lines or hanging lines should be drawn on the laying layer according to the width, and then the laying can begin. Then, the ends of the grid should be fixed with U-shaped nails (4 nails per meter width, evenly spaced).

2. After fixing the end of the grid, use a laying machine or manual method to slowly pull the grid forward, and manually straighten it every 10 meters until one roll of grid is laid, and then lay the next roll. The operation is the same as before.

3. Splicing: The length of the section to be laid is measured by the length of the roll. After covering the entire length of the grating, the overall quality of the laying should be checked, and then the next section should be laid.

When laying the next section, the grid should overlap with each other by a net distance of one grid as the overlap length, and be fixed with binding wires before continuing to lay the second section in the forward direction.

Application and function of steel plastic geogrid:

Generally, soft foundation treatment is used when the filling height is greater than 4 meters.

When soft foundation treatment is carried out, it is adopted when the roadbed filling height is between 3-4 meters or at the junction of road and bridge to prevent uneven settlement.

Widening the old road to prevent longitudinal cracks from being added at the junction of the old and new roadbeds.

Low fill and shallow excavation sections, soft foundation treatment with fill within 2 meters, and roadbed addition for poor sections
