Bidirectional geogrid

Bidirectional geogrids are made from polymers that are extruded, sheeted and perforated through a process followed by longitudinal and transverse stretching. The material has great tensile strength in both longitudinal and transverse directions, and this structure also provides an ideal interlocking system for more effective force bearing and diffusion in the soil, and is suitable for large area permanent bearing foundation reinforcement.

    Product use
    Bi-directional tensile plastic geogrid is suitable for all kinds of embankment and roadbed reinforcement, slope protection, cave wall reinforcement, large airports, car parks, wharf yards and other permanent bearing foundation reinforcement.
    The finite element method is used to study the use of two-way geogrid reinforcement bridge embankment, so as to control the problem of bridge jumping. The spacing of the reinforcement layer is analysed for its influence on the settlement of the bridgehead embankment, the distribution of vertical additional stresses, and the tensile stresses and tensile strains of the geogrid. The results show that the reinforcement treatment of bridge head embankment with reasonable scheme can effectively control the settlement of bridge head embankment, and make the settlement between bridge deck and embankment can be smooth transition, which creates favourable conditions for the control of bridge head jumping.
    Scope of application
    1, various highways, railways, airports, roadbed enhancement;
    2、The foundation enhancement of permanent bearing such as large-scale car parks and wharf yards;
    3, railway, highway slope protection, culvert enhancement;
    4, unidirectional tensile geogrid enhanced soil slopes after the second enhancement, further enhancement of soil slopes, prevent soil erosion;
    5, mine, pit reinforcement.
    Construction method
    Excavate the foundation bed, set the sand bedding layer (height difference is not more than 10cm), rolling into a platform, laying grating, the longitudinal axis should be the same as the main direction of force, and longitudinal lap 15-20cm, transverse 10cm, lap with a plastic tape tie, and in the laying of the grating, every 1.5-2m with a U-type nails fixed to the ground, laying of the geogrid should be backfilled in time with the soil material, laying of the number of layers of geogrid depending on the technical Requirements.
    Geogrid construction process requirements
    Geogrid paving surface should be a relatively flat, paving layer after acceptance, in order to prevent longitudinal skewing phenomenon, according to the width of the paving layer in the white line or hanging line, you can start paving, and then use nails to fix the end of the grille (8 nails per metre wide, even distance fixed).
    After fixing the end of the grille, use the paving machine to slowly pull the grille forward to pave, every paving 10 metres long to manually tighten and straighten once, until a volume of the grille is paved, and then pave the next volume, the same operation as before.
    After paving a volume with a 6T-10T roller from the starting point to the forward direction can be crushed once. (If paving on the middle surface layer and levelling layer, it is appropriate to use steel roller roller; if the grating is directly paved on the concrete pavement, it is appropriate to use rubber roller roller.)
    Paving: take the roll length as a unit as the section length of paving, after paving in the section length which should be paved with grating, check the quality of paving once more as a whole, and then proceed to pave the next section. The next section of paving, grating and grating can be used 10-15CM lap length, and fixed with nails or wedges to continue to the forward direction of the second section of paving. And so on, the operation requirements are the same as before.

What Applications Benefit Most from the Use of Bidirectional Geogrids?
Bidirectional geogrid find diverse applications across various industries due to their exceptional properties and versatility. Their ability to reinforce soil structures, distribute loads effectively, and enhance stability makes them invaluable in numerous civil engineering, construction, and environmental projects. Below, some of the key applications that benefit most from the use of bidirectional geogrids:
1. Road and Pavement Construction:Bidirectional geogrids play a crucial role in road and pavement construction projects. By providing reinforcement to the soil subgrade, they improve load distribution and prevent rutting and cracking. Additionally, they reduce the thickness of pavement sections required, resulting in cost savings and improved longevity of roadways.
2. Retaining Walls and Slope Reinforcement:In the construction of retaining walls and reinforced slopes, bidirectional geogrids help stabilize soil structures against lateral pressures and gravitational forces. They enhance the structural integrity of retaining walls and steep slopes, reducing the risk of erosion, soil displacement, and slope failure.
3. Embankment Stabilization:Embankments, especially those built on soft or unstable soils, benefit greatly from bidirectional geogrid reinforcement. These geogrids distribute loads uniformly, increase bearing capacity, and minimize settlement, thereby improving the stability and long-term performance of embankment structures.
4. Foundation Reinforcement:Bidirectional geogrids are commonly used to reinforce foundation structures, such as building foundations, bridge abutments, and utility pads. By enhancing soil bearing capacity and reducing settlement, they provide essential support to heavy structures, ensuring their stability and longevity.
5. Erosion Control and Soil Stabilization:In environmental restoration and erosion control projects, bidirectional geogrids are employed to stabilize soils on steep slopes, shorelines, and riverbanks. They mitigate soil erosion by reinforcing the soil matrix, promoting vegetation growth, and preventing surface runoff, thereby preserving natural habitats and preventing sedimentation in water bodies.
6. Railway Track Stabilization:Railway tracks subjected to heavy loads and dynamic forces benefit from bidirectional geogrid reinforcement. These geogrids improve track stability, reduce track settlement, and minimize ballast migration, leading to smoother train operations, reduced maintenance costs, and increased safety.
7. Landfill Liner Systems:Bidirectional geogrids are integral components of landfill liner systems, where they serve as reinforcement layers within geomembrane liners. By enhancing stability and preventing soil movement, they ensure the integrity of landfill barriers, minimize leachate migration, and protect groundwater quality.
8. Earthquake and Seismic Retrofitting:In regions prone to seismic activity, bidirectional geogrids are used in retrofitting existing structures to improve their resistance to earthquake-induced ground motions. By reinforcing soil foundations and structural elements, they enhance the seismic performance of buildings, bridges, and other infrastructure.
9. Mining and Geotechnical Engineering:In mining operations and geotechnical engineering projects, bidirectional geogrids are employed to reinforce soil and rock masses, stabilize slopes, and control ground movement. They facilitate safe and efficient excavation, reduce the risk of slope instability, and enhance overall site safety.
10. Green Roof Systems:Bidirectional geogrids are utilized in green roof systems to provide structural support to vegetation layers and distribute loads evenly across the roof surface. They enhance the stability of green roofs, improve stormwater management, and extend the lifespan of roofing materials.
