Bi-directional PP Geogrid is a new geotechnical material in China. It has high tensile strength (>100KN/m, elongation less than fifteen percent), good dimension, corrosion resistance, aging resistance (120 years of design life, underground), wide use of temperature (-50--120 degree) and so on. PP Geogrid has been widely used for dangerous slope protection. Foundation treatment, reinforced earth retaining wall engineering and some high bearing capacity structures are epoch-making new materials in the construction industry.

The bi-directional plastic geogrid PP Geogrid is used to reinforce the roadbed, and the grille and pavement materials are combined together. It can effectively distribute the load, prevent the loss of ballast and the deformation of the subgrade, and bear a greater load of the subgrade. The two-way PP Geogrid is laid on the flat bottom of the lower bearing layer according to the width of the design requirements. The upper and lower packing materials have no spines to break the debris of the two-way plastic geogrid. When the two-way plastic geogrid is laid, the direction of the high strength is arranged perpendicular to the axis direction of the embankment. The bi-directional plastic geogrid is paved horizontally. It should be stretched and stretched to avoid wrinkling, twisting or pitting. The two-way plastic geogrid is spliced vertically along the longitudinal direction, and the lap width is less than 20cm. When the roadbed is paved with bi-directional roadbed, it is prudent to deal with the treatment of subgrade diseases. The changes in the ground surface of the landslides can be roughly divided into six stages, such as, micro movement, large movement and consolidation. The surface water within the scope of the slide should be collected as soon as possible to prevent infiltration and to build drainage on the basis of full use of natural gullies. The cracks produced by concrete under normal static load, dynamic load and secondary stress are called load cracks. There are mainly 2 kinds of direct stress cracks and secondary stress cracks.
