65KN/M Plastic HDPE Uniaxial Geogrid For Retaining Wall
Description:
Polyethylene uniaxial plastic geogrid, namely HDPE UX plastic
geogrid, polyethylene UX plastic geogrid,
is a geogrid made of high-density polyethylene (HDPE) as raw
material, through plasticized extrusion sheet, punching, heating
and stretching.
Through stretching, the originally scattered chain molecules are
redirected to a linear state, which fully
improves the tensile strength and rigidity of the geogrid.
When the geogrid is laid in the soil, the bite and interlocking
between the geogrid mesh and the soil form
an efficient stress transfer mechanism, so that the local load can
be quickly and effectively diffused to
a large area of soil, thereby achieving the purpose of reducing
local destructive stress and increasing
the service life of the project.
Advantages
The outstanding advantage is that it has little tendency to deform
(creep) under long-term continuous load,
and its creep resistance is much better than that of geogrids made
of other materials, which plays an important
role in improving the service life of the project.
Application :
The product is suitable for the construction of roads, railways,
and reinforced retaining walls, dams, bridge decks,
steep slopes and geocells on the coasts of rivers, lakes and seas.
Its function is to improve the bearing capacity
of retaining walls or dams, extend the service life, reduce the
floor space, shorten the construction period,
reduce the cost, and reduce maintenance costs.
Manufacturing process
It is made of high molecular polymers that are extruded into thin
sheets, punched into regular meshes,and then
stretched longitudinally. In this process, the polymer is oriented
linearly and forms an elongated elliptical mesh
structure with uniform distribution and high node strength. This
structure has a very high tensile strength and tensile modulus.
In particular, our company's products have high early (elongation
of 2%-5%) tensile strength and tensile modulus
that exceed international standards. It provides an ideal chain
system for bearing and diffusing forces for the soil.
This product has a high tensile strength (>150Mpa), is suitable
for various soils, and is a widely used reinforcement material.
Product Uses :
Use of Polyethylene Unidirectional Plastic Geogrid:
Unidirectional tensile geogrid is a high-strength geosynthetic
material. Widely used in dams,
tunnels, docks, roads, railways, construction and other fields.
1. Geogrids can strengthen the roadbed, effectively distribute the
diffusion load, improve the stability and bearing
capacity of the roadbed, and extend the service life;
2. Geogrids can withstand greater alternating loads;
3. Geogrids prevent roadbed deformation and cracking caused by the
loss of roadbed materials;
4. Geogrids increase the self-bearing capacity of the fill behind
the retaining wall, reduce the earth pressure of
the retaining wall, save costs, extend the service life, and reduce
maintenance costs;
5. Geogrids combined with shotcrete construction methods for slope
maintenance can not only save 30%-50%
of investment, but also shorten the construction period by more
than half;
6. Adding geogrids to the roadbed and surface layer of the highway
can reduce bending and rutting, delay the appearance
of cracks by 3-9 times, and reduce the thickness of the structural
layer by 36%;
7. Geogrids are suitable for all kinds of soils, do not need to be
sourced from other places, save labor and time;
8. Geogrid construction is simple and fast, which can greatly
reduce construction costs.
