(1) Clean foundation: Excavate the slope, slope surface and floating soil at the bottom of the canal according to the requirements of the construction drawing. Soil to ensure clean and dry foundation pits;

(2) Stakeout: Stake out strictly according to the construction drawing, and make side piles, fill height, grid sideline, and slope ratio control;

(3) Laying of the grid: The geogrid is laid manually and layered on the slope.

The upper parcel forms an overwrap overlap, the length of the overwrap is not less than 100cm, and the two adjacent grids are flat joints; the tail of the grid and the unexcavated slope form an upslope extension, and the extension length is not less than 30cm, The tail is fixed; the connecting rods are overlapped with the connecting rods, and the U-shaped steel bar is anchored between the grilles and the soil.

(4) Soil-laying and roller compaction: The earth-laying of the grille is carried out by bulldozers. The bulldozers are flat, and then artificially flattened. The surface flatness does not exceed ± 5 cm.
