High Strength Uniaxial Plastic Geogrid
Uniaxial Plastic Geogrid Introduction
Plastic uniaxial geogrid is manufactured from plastic materials
which may be high-density polypropylene or high-density
polyethylene (HDPE) resins by the hot extruding process to make the
resins into thin plates, the plates are punched into the regular
holes for the formation of desired grids, and then the punching
patterns are stretched longitudinally into the desired meshes to
develop designed tensile strength.

Uniaxial Plastic Geogrid Installation
When used for reinforcing soil retaining wall, the construction
shal lbe issued as follows:
1.Set up the foundation and carry out the construction according to
the designed wall system.When the precast reinforced concrete panel
is selected, it is generally supported On the precast concrete
foundation with a thickness of 12-15cm. Its width shall not be
greater than 30cm, its thickness shall not be less than 20cm, and
its burial depth shall not be less than 60 cm to prevent the
influence of foundation frost heave.
2.Level off the wall foundation, dig and level up according to the
design requirements. Soft soil to be compacted or replaced,
compacted to the required density, should be Slightly beyond the
range of the wall;
3.Tendon laid, the direction of the main strength of the tendon
should be perpendicular to The wall,fixed with pins;
4.For wall filling, the mechanical filling should be used. The
distance between wheels and Steel bars should be at least 15 cm.
When used for reinforced earth retaining wall, the construction
method is as follows:
1. The foundation shall be set and the construction shall be
carried out according to the designed wall system. When the precast
reinforced concrete panel is selected, the thickness is generally
12-15 cm and supported on the precast concrete foundation. The
width is not more than 30cm, the thickness is not less than 20cm,
and the buried depth is not less than 60cm to prevent the influence
of foundation frost heaving.
2. The wall foundation shall be leveled, excavated and leveled
according to the design requirements. Soft soil needs to be
compacted or replaced, and compacted to the required density, which
should be slightly beyond the scope of the wall.
3. When laying the reinforcement, the main strength direction of
the reinforcement shall be perpendicular to the wall and fixed with
pins.
4. For wall filling, mechanical filling shall be adopted, and the
distance between wheel and reinforcement shall be kept at least 15
cm. After compaction, the thickness of one layer of soil is about
20-15cm.
5. During the wall construction, the wall should be wrapped with
geotextile to prevent the leakage of filling.
