Manufacturers sell two-way plastic geogrids for subgrade
reinforcement at preferential prices
About Hengquan
We have experience for more than 7 years. There are two product
lines for geogrid and geocell. Factory work 24hours a day, we sold
more than 100,000,000rmb last year(2020). Our customers are all
over the world.
Brief Introduction of Geocell Confinement System
There are two common problems at the junction of old and new roads:
one is that the design is not comprehensive, and there are many
technical difficulties in construction; the other is that the
strength of the old road is insufficient and the thickness of the
reinforcement layer is thin. The use of geogrid can make up for the
deficiencies in design and construction, and improve the tightness
of the new and old joints. Taking a highway project as an example,
the original width of the pavement is 9 m, and now it is expanded
to 15 m. The pavement structure layers from top to bottom are:
AC-13 asphalt concrete layer, AC-20 asphalt concrete layer, cement
stabilized gravel layer, graded gravel layer. Using glass fiber
geogrid material, the breaking strength is ≥50 kN/m, the breaking
elongation is ≥3%, the grid size is 25.4mm×25.4mm, and the width is
5m. After the construction is completed, the line can pass
smoothly, and the appearance and quality are better than the old
pavement structure; compared with the replacement and graded gravel
method, the use of geogrid not only reduces the cost, but also
saves maintenance costs, showing good social and economic benefits.
Geogrid System Characteristic
The orientation of the arrangement strengthens the bonding force
between the molecular chains and achieves the purpose of improving
its strength. Its elongation is only 10% to 15% of the original
sheet. If anti-aging materials such as carbon black are added to
the geogrid, it can make it have better durability such as acid
resistance, alkali resistance, corrosion resistance and aging
resistance.
1. After the first layer of geogrid is laid, start to fill the
second layer of 0.2m thick medium (coarse) sand. The method:
transport the sand to the construction site and unload it on the
side of the roadbed, and then push it forward with a bulldozer.
First fill 0.1m within 2m on both sides of the roadbed, then fold
the first layer of geogrid and fill it with 0.1m of medium (coarse)
sand. It is forbidden to fill and advance from both sides to the
middle. All kinds of machinery work on the geogrid that is not
filled with medium (coarse) sand, so as to ensure that the geogrid
is flat, without bulging or wrinkling. After the second layer of
medium (coarse) sand is leveled, the Measure horizontally to
prevent uneven thickness of filling, and use a 25T vibratory roller
to statically press twice after the copying is correct.
Factory and Equipment:
Product inventory:
In soft soil high fill engineering, laying geogrid in the middle of
30-50 cm gravel layer can form geogrid gravel cushion and give full
play to the reinforcement role of excavated geogrid. On the one
hand, the geogrid has strong shear resistance, which can
effectively prevent the gravel from falling into the soft
foundation, and promote the grid and gravel to be embedded closely
to form a stable whole. On the other hand, the geogrid will form a
horizontal plane in terms of drainage, which can be used as a
drainage channel. After the subgrade is formed, it can effectively
reduce the soil moisture content. Third, the geogrid is laid above
the soft foundation, which will produce isolation effect,
It is not only convenient for construction, but also can restrain
the lateral deformation of foundation and reduce uneven settlement.
Fourth, increase the shear resistance of soil and change the
physical and mechanical properties of soft foundation.
