As a professional geogrid manufacturer, Hengze New Material Group Co., Ltd. will summarize the construction precautions and quality assurance measures for geogrids.

1. A dedicated person shall be appointed on the construction site to be responsible for construction records, and the lap width and longitudinal lap length shall be checked at any time. If any abnormalities are found, they shall be promptly studied and resolved.
2. To strengthen the management and inspection of materials, testing personnel should check at any time whether the incoming materials meet the requirements of the drawing design.
3. When laying geogrids, the lower bearing layer should be flat and dense. Before laying, on-site construction personnel should conduct inspections.
4. To ensure the width of the roadbed, each side will be widened by 0.5 meters.
5. The on-site person in charge should always pay attention to the installation of geogrids, which should be straightened and not curled or twisted.
6. The longitudinal overlap length of the geogrid is 300mm, and the transverse overlap length is 2m. The on-site person in charge should inspect at any time.
7. Insert U-shaped nails in a plum blossom shape every 500mm along the overlapping area, and insert U-shaped nails in a plum blossom shape every 1m in other non overlapping areas. The on-site responsible person should conduct random inspections at any time.
8. The direction of high strength of the geogrid should be consistent with the direction of high stress, and heavy vehicles should be avoided from driving directly on the laid geogrid as much as possible.
6. Nail U-shaped nails: Insert U-shaped nails in a plum blossom shape every 500mm along the overlapping area, and insert U-shaped nails in a plum blossom shape every 1m in other non overlapping areas.
7. Backfill earthwork: After the laying is completed, backfill the roadbed slope with earthwork to seal the exposed grille.
8. When the upper bearing layer is made of gravel, the process flow of the gravel cushion layer is as follows: inspection of gravel quality → layered paving of gravel → watering → compaction or rolling → leveling and acceptance.
