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.
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.

Application of backfill in platform
There is a big difference in stiffness between rigid abutments and
semi-rigid fill subgrades, which leads to uneven settlement of
bridges and subgrades, resulting in the phenomenon of bridge head
jumping. In the backfill construction of the platform, the laying
of geogrid can form anchoring force, interlocking force, and
frictional resistance, promote the formation of the structure and
the backfill as a whole, effectively reduce the settlement
difference, and improve the driving comfort.
