I am a site using two-way 80 plastic geogrid, the need to use U type nails specifications and prices? Consultation with the construction process, thank you.Correction: two-way 80 steel plastic geogrid.
Key points of quality technology1. The quality of geogrid conforms to the requirements of drawings or specifications.2, the laying of geogrid should be straightened straight down to the underlying layer. There should be no distortion, wrinkle, overlap, the use of artificial tension, the use of U type nails fixed on the surface of the base.3, the connection between the geogrid should be solid, its stack length is not less than 30cm.4, the surface of the soil layer should be smooth, less than 8cm geogrid Embankment Filler, the maximum particle size should not be greater than 6cm.5, the geogrid is laid in a timely manner in its fill, in order to avoid its exposure to the sun for a long time, not because of the soil geogrid.6, the filling layer paving, layered rolling. On the basis of the method, the upper subgrade filling.7, different levels of geogrid connection position should be staggered. Construction should avoid transport vehicles and other construction machinery in the shop has spread to direct rolling and tension of Geogrid on location.8, the key of laying geogrid is to ensure continuity, to avoid distortion, fold, overlap, pay special attention to avoid excessive tension, to prevent exceeding the tensile strength and deformation limit failure and tear.Steel grating 80KN bandwidth should be between 1.6-1.8cm, fixed with U nails as long as the diameter larger than this size OK, as for the price, hardware stores should have to sell, not very expensive.
Base leveling and laying geogridAfter the impact and compaction of the foundation, the flat base machine is used to flatten the uneven base after impact, so as to meet the requirements of the smoothness of the geogrid. And then use the iron three wheel roller for the foundation of the light roller, after testing to meet the requirements of the construction work of geogrid. Laying process and quality to meet the requirements of design and specification.
First, the construction steps1, the basement cleaning and compactionClear the surface of the original surface and exclude surface water, clear surface thickness of 30cm, clear the table after the impact roller compaction base, the compaction degree of not less than 93%.
