Construction method of biaxial geogrid
Construction method of biaxial geogrid Construction site: require compaction and levelling, horizontal shape, remove spikes and protrusions. geogrid laying: on the site of levelling and compaction, laying should be flat, no wrinkles, as far as possible tension.

Geogrid laying construction points
1ã€Construction site: require compaction and levelling, horizontal shape, remove spikes and protrusions.
2, grille laying: on the site of levelling and compaction, laying should be flat, no wrinkles, as far as possible tension. Fixed with nails and soil and stone weight, the connection between the grating laid with polyethylene rope for manual tying lap, lap width of not less than 10cm. large area after laying, to adjust the overall straightness. When filling and covering a layer of soil, not crushed before, should be again with artificial or mechanical tension grating, strength should be uniform, so that the grating in the soil for the taut state.
3, the choice of filler: should choose the soil mechanical properties of stable gravel soil and sand, require filler performance by the water content of the impact of small. Filler particle size shall not be greater than 15cm, and pay attention to the control of filler grading to ensure the compaction weight.
4, filler paving and compaction: when the grating paving positioning, should be filled in time to cover, bare time shall not exceed 48 hours, can also take the side of paving and backfilling of the flow of operation method. First in the two ends of the paving filler, the grille fixed, and then to the middle of the advance. The order of rolling is the first two sides after the middle. Rolling when the pressure wheel can not directly contact with the tendon material, uncompacted reinforced body generally do not allow vehicles to drive on it, so as to avoid tendon material dislocation. The filler should be compacted in valves, and the compaction must reach 94 %.
