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.

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.
Features:
- Cost effective.
- High seam strength.
- Good erosion control.
- High in-plane stiffness.
- Good aperture stability.
- Excellent load distribution.
- Long term structural stability.
- Excellent corrosion resistance.
- Effective mechanical interlock system.
- Good corrosion resistant performance.
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.
