What Problems Should Be Paid Attention To When The Glass Fiber Geogrids Are Rolled
After the end of the roadbed treatment, the fiberglass geogrid should be laid. Before laying, it is necessary to monitor the quality of its raw materials to ensure that the quality can reach the standard and conform to the provisions of the application I. During the placement and laying of the fiberglass grille, it is necessary to prevent long-term exposure to the sun to weaken its performance. The glass fiber geogrid should be laid vertically on the roadbed line of the highway to ensure the quality of the lap position to reach the standard, the connection is stable and the loosening is prevented. The lap length is about 20cm, and the strength of the lap position is greater than the tensile strength of the raw material. In addition, the quality of the glass fiber geogrids should be consistent with the construction provisions, and the tensile strength should be more than 100kN/m. During the construction period, it should be maintained continuously, without torsion, fold and other problems, and tighten the grille, so that it can be stressed, ensure its levelness, and closely follow the lower bearing surface. At the end of the laying, the use of steel nails on the glass fiber geogrid to be fixed, to ensure that the structure is more stable; At the same time, it should also ensure that the surface in the lower bearing layer is very smooth,
During the construction of filling soil, the two sides and the middle part should be filled first, and the two sides should be filled symmetrically. After the end, the middle part should be filled, and the middle part can be filled first. The use of muck truck to send the packing to the construction site, the unloading in the pavement after the end of the paving, the unloading height should be less than 1m. All trucks and construction facilities can not walk on the glass fiber geogrid, but should run along the embank to prevent damage to the glass fiber geogrid
The bad. At the same time, but also to control the packing particle size, the general particle size should not be greater than 6cm.
