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
Geogrid is a new type of synthetic material with many technical
advantages. This paper introduces the application of geogrid in
soft soil foundation, filling road section, pavement construction,
and backfill soil, points out the key points of construction
technology, and analyzes it in combination with engineering cases.
It is hoped to provide experience and reference for similar
projects, improve the construction quality of highway projects, and
obtain economic and social benefits.
Geogrid System Characteristic
When the external force acts on the grid unevenly, the mesh will
deform due to the transverse tensile stress, which shows the
restraint effect and has strong adaptability to the non-uniform
distributed load. The geogrid has high friction resistance. When
used as reinforcement, it can enhance the shear strength of the
structural layer and improve the overall stability.
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.
