What is Geogrid?
Plastic geogrid is a square or rectangular polymer mesh formed by stretching. It can be divided into unidirectional stretching and biaxial stretching according to the different stretching directions during its manufacture. It is punched on the extruded polymer plate (most of the raw materials are polypropylene or high-density polyethylene), and then directionally stretched under heating conditions. single
The upward stretching grid is only made by stretching along the length of the plate, and biaxial stretching
The grating is made by stretching the unidirectional stretching grating in the direction perpendicular to its length.

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.
