Base Reinforcement Using Pet Biaxial Geogrid For Road Construction
Earthwork
About Hengquan
We have experience for more than 7 years. There are two product
lines for geogrid and geocell. Factory work 24hours a day, we sold
more than 100,000,000rmb last year(2020). Our customers are all
over the world.
Brief Introduction of Geocell Confinement System
The bidirectional geogrid is made of high molecular polymer through
extrusion, plate forming, punching and then longitudinal and
transverse stretching. The material has great tensile strength in
both longitudinal and transverse directions. This structure can
also provide a more effective force bearing and diffusion ideal
interlocking system in the soil, which is suitable for large-scale
permanent bearing. foundation.
Geogrid System Characteristic
The orientation of the arrangement strengthens the bonding force
between the molecular chains and achieves the purpose of improving
its strength. Its elongation is only 10% to 15% of the original
sheet. If anti-aging materials such as carbon black are added to
the geogrid, it can make it have better durability such as acid
resistance, alkali resistance, corrosion resistance and aging
resistance.
When laying geogrids, the direction of force is required to be
perpendicular to the axis direction of the roadbed to ensure
smoothness, tension, no bulge, and overlap according to the design
width. First, use U-shaped rivets to fix, the main force direction
of the grille, try to ensure that the whole length has no joints,
and control the overlap width to be more than 20 cm; The overlap
width should be controlled at more than 10 cm; if two or more
layers of grids are used, the upper and lower layers should be
staggered. After the large area is laid, adjust the straightness;
try to shorten the time when the grille is exposed
After filling a layer of soil, before rolling, the grid should be
tensioned again to ensure that the grid is in a state of tension
and stress.
Factory and Equipment:
Product inventory:
In soft soil high fill engineering, laying geogrid in the middle of
30-50 cm gravel layer can form geogrid gravel cushion and give full
play to the reinforcement role of excavated geogrid. On the one
hand, the geogrid has strong shear resistance, which can
effectively prevent the gravel from falling into the soft
foundation, and promote the grid and gravel to be embedded closely
to form a stable whole. On the other hand, the geogrid will form a
horizontal plane in terms of drainage, which can be used as a
drainage channel. After the subgrade is formed, it can effectively
reduce the soil moisture content. Third, the geogrid is laid above
the soft foundation, which will produce isolation effect,
It is not only convenient for construction, but also can restrain
the lateral deformation of foundation and reduce uneven settlement.
Fourth, increase the shear resistance of soil and change the
physical and mechanical properties of soft foundation.
