For Protective Soil
Uniaxial Plastic Geogrid Introduction
The unidirectional geogrid is a kind of high molecular polymer as
the main raw material, adding certain anti-ultraviolet, anti-aging
additives, after unidirectional stretching, the originally
distributed chain-shaped molecules are re-orientated and arranged
in a linear state. It is a high-strength geotechnical material that
is pressed into a thin plate and punched with regular meshes, and
then stretched longitudinally. . In this process, the polymer
becomes a directional linear state and forms an oblong network
integral structure with uniform distribution and high node
strength.

Uniaxial Plastic Geogrid Feature
1. The polymer is in the shape of a directional line, forming a
long oval network structure with uniform distribution and high node
strength. This structure has quite high tensile strength and
rigidity, and provides ideal bearing capacity and diffusion
interlocking system for the soil.
2. The outstanding advantage of unidirectional plastic geogrid is
that it has a small tendency to deform (creep) under long-term
continuous load, and its creep resistance is much better than other
materials, which plays an important role in improving the service
life of the project.
3. The occlusion and interlocking of the grid and the soil
constitutes an efficient stress transmission mechanism, which
enables the local load to be quickly and effectively spread to a
large area of soil, thereby reducing local damage stress and
increasing the service life of the project.
Plastic Uniaxial Geogrid Fuction
1. One-way geogrid is used to reinforce weak foundations: Geogrids
can quickly increase the bearing capacity of foundations, control
the development of settlement, and confine the road base to
effectively distribute the load to a wider base. Thereby reducing
the thickness of the base layer, lowering the project cost,
shortening the construction period and prolonging the service life.
2. One-way geogrid is used to reinforce asphalt or cement pavement:
the geogrid is laid on the bottom of asphalt or cement pavement,
which can reduce rutting depth, prolong the fatigue life of the
pavement, and reduce the thickness of asphalt or cement pavement to
save cost.
3. The unidirectional geogrid is used to reinforce the embankment
dam and the retaining wall: the traditional embankment, especially
the high embankment, often needs to be overfilled and the edge of
the shoulder is not easy to compact, which will cause the slope to
be flooded and collapsed in the later stage. The phenomenon of
instability occurs from time to time, and at the same time, a
gentle slope is required, which covers a large area, and the
retaining wall has the same problem. The use of geogrids to
reinforce the embankment slope or retaining wall can reduce the
area occupied by half. Area, extend the service life, reduce the
cost by 20-50%.
4. Unidirectional geogrid is used to reinforce rivers and sea
dikes: it can be made into stone cages, and then used together with
grids to prevent the dam from being washed by seawater and cause
collapse. The stone cages are permeable, can slow down the impact
of waves, prolong the life of the dam, and save Manpower and
material resources shorten the construction period.
5. One-way geogrid is used to treat garbage landfills: the
combination of geogrid and other soil composite materials to treat
garbage landfills can effectively solve the problems of uneven
foundation settlement and derived gas emissions, and can maximize
The storage capacity of the landfill.
Uniaxial Plastic Geogrid Usage
Unidirectional stretching geogrid is used to reinforce the
embankment dam 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 compact,
which leads to the rainwater infiltration and collapse of the slope
in the later period. The phenomenon of instability occurs from time
to time, and at the same time, a gentle slope is required, which
covers a large area, and the retaining wall has the same problem.
The use of geogrids to reinforce the embankment slope or retaining
wall can reduce the area occupied by half. Area, extend the service
life, reduce the cost by 20-50%; unidirectional stretching geogrid
can also be used to strengthen rivers and sea dikes: it can be made
into a stone cage, and then used with the grid to prevent the dike
from being washed by sea water and cause collapse. The cage has
permeability, can slow down the impact of waves, extend the life of
the dam, save manpower and material resources, and shorten the
construction period.
Construction method of one-way geogrid:
Construction method of one-way geogrid:
When used on roadbeds and pavements, the construction method is the
same as the two-way geogrid. When used for reinforced soil
retaining walls, the construction methods are as follows: 1. Set up
the foundation and carry out construction according to the designed
wall system. When precast reinforced concrete panels are selected,
they are generally supported on a precast concrete foundation with
a thickness of 12-15 cm. 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 frost heave of the
foundation.
3. For laying of reinforcements, the main strength direction of the
reinforcements should be perpendicular to the wall and fixed with
pins. isD Feicheng Lianyi Engineering Plastics Co., Ltd.
4. The wall shall be filled with soil by mechanical filling, and
the distance between the wheel and the reinforcement shall be kept
at least 15 cm. After compaction, a layer of soil is about 20-15 cm
thick. isD Feicheng Lianyi Engineering Plastics Co., Ltd.
5. During wall construction, geotextiles should be covered on the
wall to prevent leakage of the fill.
