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
Geogrid has large tensile strength and tensile modulus, which can
realize the uniform distribution of load and stress in a large
area. In the soft foundation or soil layer, the application of
geogrid can reduce and disperse the concentrated stress of the
upper load on the soft foundation; In the asphalt structure layer,
the creep effect of asphalt can be weakened and the cracking of
asphalt layer can be avoided. The mesh shape of geogrid is the
same, and the shear resistance of upper particles and lower
particles will not be affected. The deformation and displacement
caused by load compaction can be avoided under the action of
stiffness, tensile strength and mesh interlocking,
Improve particle compaction effect.
After the subgrade is leveled and compacted, the geogrid shall be
laid in time and positioned according to the design requirements,
and the soil shall be filled and covered in time after anchoring,
so as to shorten the exposure time as much as possible. If
necessary, backfill can be done at the same time as the grid is
laid to improve paving efficiency. In terms of specific operation,
firstly, the filler is spread on both ends, and after fixing the
grid, it is gradually advanced to the middle. During the rolling
operation, follow the rolling sequence of the two sides first, then
the middle. The pressing wheel cannot directly contact the grille,
and cannot drive on the uncompacted reinforced body. During the
layer-by-layer compaction, the thickness of each layer is
controlled at 20-30 cm, and indicators such as compaction and
flatness are checked in time to meet the design requirements.

Application in filling section
During the subgrade filling construction, if loose filler is used,
it will affect the subgrade sloping construction, cause land waste,
increase the construction cost, and is not conducive to the later
rolling operation. Laying Geogrid on the slope can improve the
slope stability and achieve the compactness index; In the road
reconstruction and expansion project, the application of geogrid
can promote the close combination of old subgrade and new subgrade,
improve the integrity of subgrade, ensure the uniform distribution
of load and avoid the deformation caused by stress concentration.
