Plastic Geogrid
Uniaxial Plastic Geogrid Introduction
Hengquan is a professional uniaxial plastic geogrid manufacturers,
supply high quality&factory price uniaxial plastic geogrid,
welcome to consult wholesale uniaxial plastic geogrid for sale.
Uniaxial plastic geogrid is a kind of polymer as the main raw
material, add certain UV protection, anti-aging agent, after
uniaxial tensile scattered the original distribution of chain form
molecular reorientation arranged in linear state, the extrusion
pressure into a sheet of rules of mesh again, then the longitudinal
tensile and high strength geotextile materials. In this process,
the polymer is oriented linearly and forms a long elliptic network
with uniform distribution and high joint strength.

Construction method
When used for Subgrade and pavement, the construction method is the
same as that of bidirectional geogrid.
When used for reinforced earth retaining wall, the construction
method is as follows:
1. The foundation shall be set and the construction shall be
carried out according to the designed wall system. When the precast
reinforced concrete panel is selected, the thickness is generally
12-15 cm and supported on the precast concrete foundation. The
width is not more than 30cm, the thickness is not less than 20cm,
and the buried depth is not less than 60cm to prevent the influence
of foundation frost heaving.
2. The wall foundation shall be leveled, excavated and leveled
according to the design requirements. Soft soil needs to be
compacted or replaced, and compacted to the required density, which
should be slightly beyond the scope of the wall.
3. When laying the reinforcement, the main strength direction of
the reinforcement shall be perpendicular to the wall and fixed with
pins.
4. For wall filling, mechanical filling shall be adopted, and the
distance between wheel and reinforcement shall be kept at least 15
cm. After compaction, the thickness of one layer of soil is about
20-15cm.
5. During the wall construction, the wall should be wrapped with
geotextile to prevent the leakage of filling.

Uniaxial Plastic Geogrid Application
| Reinforcing soft foundation | Geogrid can quickly improve the bearing capacity of foundation,
control the development of settlement, and can effectively
distribute the load to the wider subbase, so as to reduce the base
thickness, reduce the project cost, shorten the construction period
and prolong the service life. |
| Reinforced asphalt or cement pavement | Geogrid laid at the bottom of asphalt or cement pavement can reduce
rutting depth, prolong pavement fatigue life, and reduce asphalt or
cement pavement thickness to save cost. |
| Reinforcement of embankment slope and retaining wall | The traditional embankment, especially the high embankment, often
needs to be overfilled, and the edge of the shoulder is not easy to
be compacted, which leads to the rain erosion of the slope in the
later stage, and the phenomenon of collapse and instability occurs
from time to time. At the same time, a gentle slope is needed,
which covers a large area, and the retaining wall also has the same
problem Service life, reduce cost by 20-50%. |
| Strengthening river seawalls | The gabion can be made into gabion and used together with the grid
to prevent the dam from collapsing due to sea water scouring. The
gabion has permeability, can slow down the impact of waves, prolong
the life of the dam, save manpower and material resources, and
shorten the construction period. |
| Disposal of landfills | The combination of Geogrid and other geosynthetics can effectively
solve the problems of uneven settlement of foundation and emission
of derived gas, and improve the storage capacity of landfill site
to the maximum extent. |
