Qingji: Excavate the slope according to the construction drawings, remove the floating soil from the slope surface and channel bottom, ensuring the subgrade flatness does not exceed ±5cm. In case of surface water accumulation, it should be pumped out in advance, and the soft soil soaked by water should be cleared, ensuring the foundation pit remains clean and dry.

Pattern making: Strictly follow the construction drawings for pattern making, ensure proper edge stakes, fill soil height, grating edge lines, and slope gradient control.

(3) Geogrid Laying: The geogrid is laid in layers manually, with the upper layer wrapping around the slope face to form an overlap, with the overlap length not less than 100 cm. Adjacent geogrids are joined flatly; the end of the geogrid extends upwards along the slope face, with the extension length not less than 30 cm and the end securely fastened. The geogrids are connected with joining bars, and anchored to the soil mass with U-shaped steel bars.

(4) Soil spreading and compaction work: The soil spreading for the grating is carried out using a bulldozer to feed in, followed by a rough leveling by the bulldozer and then a fine leveling by hand, ensuring the surface flatness is no more than ±5 cm.
