Anyang City is Tyrone domestic limited liability company is ISO9001 certified by the industry's first enterprise geogrid construction method (1) First release of embankment slope lines accurately, in order to ensure the roadbed width of the widening each side of 0.5m, to a good drying After leveling the base soil in vibratory roller with a 25T static pressure twice, then 50T shock pressure four times, the local man with uneven leveling. (2) bedding in 0.3m thick (coarse) sand, after leveling and artificial machinery, 25T static pressure twice the vibration roller. (3) laying geogrid. When laying geogrid bottom should be smooth, dense, generally should be tiled, stretched, not overlapping, not curl, kink, two adjacent overlapping geogrid to be 0.2m, and the base along the lateral take on the geogrid then part of the 1-meter intervals were interspersed with 8 wire connection, and in laying the grid on every 1.5-2m with U-nails on the ground. (4) laid the first layer of geogrid, began filling the second floor set in 0.2m thick (coarse) sand, its methods: car transport sand to the site landed at the side of the embankment, and then drive to push forward with a bulldozer , first within 2 m of embankment filling on both sides of 0.1m, put the first layer of geogrid turned off and then fill in the 0.1 m up in the (coarse) sand, filling to the middle against both sides and forward, against the kinds of machinery in the absence of filling in the (coarse) sand to pass on a job geogrid, which can guarantee the geogrid flat and can not afford drums, do not wrinkle, to be the second layer (coarse) sand formation, the level should be measure to prevent the filling of uneven thickness, level and correct copy to be used after the HIP 25T vibratory rollers twice. (5) The second layer of geogrid construction method the same way as with the first layer, and finally filling the middle 0.3m (coarse) sand, filling the first layer with the same method, with 25T static roller twice, so subgrade reinforcement to have been disposed of. (6) in the third layer (coarse) sand After rolling, the longitudinal slope along the road on both sides of the laying of two geogrid, lapping 0.16m, and using the same method of connection is good, then start earthwork construction operations. Laying geogrid for slope protection, must be laid on each measure edges, each side of the slope after renovation to ensure that geogrid slope buried within 0.10m. (7), filling each two-slope geogrid soil, that is, when the thickness of 0.8m on both sides of the same time to be laying a layer of geogrid, and so on, until the shop to the shoulder under the surface soil. (8) roadbed construction is completed, timely repair of slope, and the puzzle pieces of dry stone toe protection, widening of the roadbed in addition to 0.3m on each side, the sink and set aside the amount of 1.5%.
