HQ1: Typical Geogrid
What is Geogrid?
Geogrid is a kind of main geosynthetics. Compared with other
geosynthetics, it has unique performance and efficacy. Geogrid is
often used as reinforcement of reinforced soil structure or
composite material. Geogrids are divided into four categories:
Plastic geogrids, steel plastic geogrids, glass fiber geogrids and
glass fiber polyester geogrids.
Specifications:
- Product name: geogrid.

In the manufacturing of plastic geogrid, the polymer will rearrange
and orient with the heating extension process, which strengthens
the bonding force between molecular chains and achieves the purpose
of improving its strength. Its elongation is only 10% ~ 15% of that
of the original plate. If carbon black and other anti-aging
materials are added to geogrids, they will have better durability
such as acid, alkali resistance, corrosion resistance and aging
resistance.
Features:
- Cost effective.
- High seam strength.
- Good erosion control.
- High in-plane stiffness.
- Good aperture stability.
- Excellent load distribution.
- Long term structural stability.
- Excellent corrosion resistance.
- Effective mechanical interlock system.
- Good corrosion resistant performance.
Applications:
When geogrid is applied in high fill subgrade, the position and
number of layers of geogrid shall be determined first. In the
design, the main idea is to determine the layer of geogrid first,
and then determine the number of layers according to the mechanical
properties of geogrid. For example, in the reconstruction and
expansion project of Shenyang Dalian Expressway, there are many
inland river networks and most paddy fields, which is not conducive
to the stability of subgrade. When using geogrid for construction,
the construction party shall lay a layer of steel plastic composite
belt grid 20cm below the subgrade top. At this time, the design
structure and combined force of geogrid shall be designed with the
longitudinal breaking load per linear meter as 60kn / M and the
transverse breaking load per linear meter as 20KN / M as the
control load. In the design of geogrid, we should not only ensure
its sufficient strength, but also calculate the bursting strength,
puncture strength, holding tensile strength, elongation, tear
strength and other properties of the material. The specific project
shall be determined according to the nature of engineering
structure, size, use requirements, load, construction conditions
and the characteristics of geosynthetics.
Construction method
Construction method of biaxial geogrid: when the biaxial geogrid is
used for Subgrade and pavement, the subgrade bed shall be
excavated, the sand cushion shall be set (the height difference
shall not be greater than 10cm), the platform shall be rolled into
a platform, and the grid shall be laid. The longitudinal axis shall
be consistent with the main stress direction, with a longitudinal
lap of 15-20cm and a transverse lap of 10cm. The lap joint shall be
bound with plastic tape, and the laid grid shall be fixed on the
ground with U-nails every 1.5-2m, The geogrid laid shall be
backfilled with soil materials in time, and the number of layers of
geogrid laid depends on the technical requirements.
