HQ1: Typical Geogrid
What is Geogrid?
The use of unidirectional grid can enhance the subgrade of the project, reduce the loss of subgrade materials and cause unnecessary subgrade deformation and cracking, so as to effectively prevent the diffusion load, bear greater bearing load, improve the stability and bearing strength of the subgrade, and prolong the service life. Biaxial geogrid biaxial tensile plastic geogrid is a kind of high-strength geogrid formed by extrusion and then longitudinal and transverse stretching with polypropylene as the main raw material. It can also improve the bearing capacity of the soil, reduce the pressurization of external forces, reduce the cost, have a long service life, and save the cost. It is the first choice for engineering projects. Its product advantages can also be used in subgrade reinforcement, slope protection, parking lot, wharf, airport, highway, etc., which can maintain and enhance geological functions effectively and long-term.

Fuction:
The polymer of plastic uniaxial geogrid is oriented in a linear state and forms a long elliptical network-like integral structure with uniform distribution and high joint strength. This structure has a relatively high tensile strength and rigidity, providing the ideal combination of force bearing and diffusion for the soil.
The outstanding advantage of the one-way uniaxial plastic geogrid is that the tendency of deformation (creep) under long-term continuous load is small, and the creep strength is much better than the geogrid of other materials, which plays an important role in improving the service life of the project.
The occlusion and interlocking action between the grid mesh and the soil constitutes an efficient stress transmission mechanism, so that the local load can be quickly and effectively diffused into the large-area soil, thereby reducing the local failure stress. To improve the service life of the project.

Applications:
Application of biaxial geogrid: biaxial plastic geogrid is used to strengthen the subgrade of various highways and railways. Increase the bearing capacity of subgrade and extend the service life of subgrade; Prevent cracks on the pavement; Reduce repair costs; Reduce the construction period. The biaxial geogrid is applicable to the permanent foundation reinforcement of large parking lot and wharf freight yard. Increase the bearing capacity of the foundation and guard the ground against collapse, which can make the ground elegant and neat; The construction is convenient, time-saving and labor-saving. Bidirectional geogrid is applied to the secondary reinforcement of soil slope reinforced by unidirectional tensile plastic geogrid.
Construction method
Construction method of biaxial geogrid: excavate the subgrade bed, set sand cushion (height difference not more than 10 cm), roll it into a platform, and lay the grid. The longitudinal axis shall be consistent with the main stress direction. The longitudinal lap shall be 20 cm and the transverse lap shall be 10 cm. The lap joint shall be bound with plastic tape, and the paved grid shall be fixed to the ground with U-nails every two meters, The geogrid laid shall be backfilled with soil materials in time, and the number of layers of geogrid laid depends on the technical requirements.
