Application Of Pp/Pe/Hdpe Uniaxial Geogrid In Reinforcement Of Retaining Wall And Abutment
Uniaxial Plastic Geogrid Introduction
Polyethylene uniaxially stretched geogrid is made of high-density
polyethylene (HDPE) as raw material, plasticized, extruded,
punched, heated, and stretched. Through stretching, the originally
scattered chain-shaped molecules are reoriented to a linear state,
which fully improves the tensile strength and rigidity of the grid.
Laying it in the soil, through the occlusion and interlocking
between the grid mesh and the soil, a stress transmission mechanism
is formed, so that the local load can quickly and effectively
spread to a large area of soil, thereby achieving The purpose of
reducing local damage stress and increasing the service life of the
project.
The outstanding advantage of polyethylene uniaxially stretched
geogrid is that it has little tendency to deform (creep) under
long-term continuous load, and its creep resistance is much better
than other geogrids, which is important for improving the service
life of the project. effect.
This product is suitable for the construction of roads, railways
and reinforced retaining walls, dams, bridge decks, steep slopes
and geocells on the coast of rivers and lakes. Its function is to
increase the bearing capacity of the retaining wall or dam, extend
the service life, reduce the floor space, shorten the construction
period, reduce the construction cost, and reduce the maintenance
cost.
The unidirectionally stretched geogrid is formed by extruding a
high molecular polymer into a thin plate, punching a regular mesh,
and then stretching it longitudinally. In this process, the polymer
becomes a oriented linear state and forms an oblong network
integral structure with uniform distribution and high node
strength. This kind of structure has quite high tensile strength
and tensile modulus, especially our company's products of this kind
have a high early stage (elongation rate of 2%-5%) tensile strength
and tensile modulus that exceed the international level. . It
provides the soil with an ideal interlocking system for bearing and
spreading forces. The product has high tensile strength
(>150Mpa), adapts to various soils, and is currently a widely
used reinforcement material.

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.
It can reasonably prevent construction damage caused by being
crushed and destroyed by the machine during the whole process of
construction
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
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
costs.
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:
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.
