Uniaxial Plastic Geogrid Introduction
What kind of material is one-way geogrid?
1. The product uses high molecular polymer as the core raw
material, and adds a condition that can prevent ultraviolet rays,
and adds an auxiliary base material that is resistant to aging.
Through unidirectional stretching, the originally scattered
chain-type molecules are rearranged, which is shown as Linear
2. After the polymer material is extruded by the extrusion
equipment of the geogrid manufacturer, it is pressed into a thin
plate to form a regular perforated net. After longitudinal
stretching, high-strength geomaterials can be formed.
3. The entire stretching process can improve the orientation
performance of the molecules, showing a linear arrangement state,
which can be evenly distributed, mainly with an elliptical network
structure with high node strength and an oblong network structure.

Uniaxial Plastic Geogrid Feature
With high compressive strength, low stress relaxation, and
integration into various natural environmental soil layers, it can
completely achieve the application of high and large retaining
walls in expressways.
It can reasonably improve the interlocking of the reinforcing rib
installation surface, the effect of tooth occlusion, the huge level
of improvement of the bearing capacity of the roadbed, the
reasonable side offset of the tube bundle sand, and the improvement
of the firmness of the roadbed.
Compared with traditional grids, it has the characteristics of high
compressive strength, strong load-bearing capacity, corrosion
resistance, embrittlement resistance, high friction resistance,
well-proportioned holes, convenient construction, and long service
It is more integrated into the seabed work and the reinforcement of
the river bank structure, which solves the bottleneck problems of
low compressive strength, poor corrosion resistance, and short
application cycle caused by long-term sea surface abrasion caused
by other raw materials made of gabion cages.
It can reasonably prevent construction damage caused by being
crushed and destroyed by the machine during the whole process of
Plastic Uniaxial Geogrid Fuction
What is the function of the one-way geogrid? The one-way grille is
commonly used in northern areas. The two-way geogrid is mainly used
in areas that have different requirements for the positive and
negative increase limits of the geogrid in different regions and in
different seasons, climate, orientation, natural disasters, and
production environment. Especially when the two-way direction is
negative increase limit, the two-way grid should be used to fill
these amounts to play a filling role. Definition and principle of
one-way geogrid A one-way geogrid is a three-dimensional geogrid
used in the contaminated area of stone and gravel waters. The
one-way grille is mainly aimed at the water environment of stone
and crushed stone. The product quality is advanced, the structure
is simple, and the construction is convenient. The one-way grid can
appear as a green product in some cases, and is often used in urban
environmental landscapes where the green area is large and the
negative increase limit is relatively large. At the same time, the
garden three-dimensional vehicle with one-way grille can also be
used in special orientation (head or tail). Definition and
principle of two-way geogrid Two-way geogrid is aimed at water
pollution and overall pollution inside the stratum. The application
of two-way grille is wider than one-way, and it must be adjusted
according to the conditions after construction. The construction of
two-way grids causes great natural and artificial pollution to the
building and the surrounding water body, and the construction is
cumbersome, and the flexibility of combination and design is not
Uniaxial Plastic Geogrid Usage
Main use of single plastic geogrid
1. Used to reinforce weak foundations: Geogrids can quickly
increase the bearing capacity of the foundation, control the
development of settlement, and the confinement effect on the road
base can effectively distribute the load to a wider base, thereby
reducing the thickness of the base. Reduce project cost, shorten
construction period and extend service life.
2. Used for reinforced asphalt or cement pavement: Geogrid is laid
on the bottom of asphalt or cement pavement, which can reduce
rutting depth and prolong the fatigue life of the pavement. It can
also reduce the thickness of asphalt or cement pavement to save
3. Used to reinforce embankment dams and retaining walls:
traditional embankments, especially high embankments, often need to
be overfilled and the edges of the shoulders are not easy to
compact, which will cause the slopes to be flooded by rain and
collapse and lose stability. Occurred, 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 and extend the service life. , Reduce the
cost by 20-50%. 4. Used to reinforce rivers and sea dikes: it can
be made into stone cages and used together with grids to prevent
the dam from being washed by sea water and cause collapse. The
stone cages are permeable and can slow the impact of waves, prolong
the life of the dam, save manpower and material resources, and
shorten the construction period. .
5. Used to deal with garbage landfills: the combined use of
geogrids and other soil composite materials to deal with garbage
landfills can effectively solve the problems of uneven foundation
settlement and derived gas emissions, and can maximize the storage
of garbage landfills ability.
6. Special purpose: low temperature resistance. The low-temperature
resistant geogrid of Liantuo Company, after repeated heating and
cooling cycles at -45°C to 50°C for 200 times, all performance
indicators meet the requirements, and have passed the test of the
Qinghai-Tibet Railway, and are suitable for the northern frozen
soil. , Frozen soil rich in ice, and permafrost with high ice
content, poor geology.
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
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.
