TX150 TX160 PP Plastic Geomalla Triaxial Geogrid Used In Road Reinforcement Construction

PP Traxial Geogrid is manufactured from polypropylene,mainly applied in strengthening soft
ground of highway,railway,slope protecting projects, airfields etc.It can increase stability and
loading capacity of fundus,prolong the project life.

Definition and structural features

1. Three-dimensional reinforced structure

The three-way grid is a triangular grid structure made of high molecular polymers such as polypropylene (PP) through extrusion, punching, and multi-directional stretching (0°, 30°, 90° or longitudinal/lateral/Z direction) processes. Its rib section is rectangular, the inner hole is an equilateral triangle, and the outer contour is a regular hexagon, achieving a three-dimensional reinforcement effect.

2. Mechanical advantages

• Multi-directional high tensile strength: It has high tensile strength in the longitudinal, transverse and oblique directions, and the nodes are strong in integrity and not easy to deform.
• Efficient interlocking effect: The triangular grid can tightly constrain soil and stone particles, reduce displacement, and improve the stiffness of the composite.

Key performance advantages

1. Improved engineering stability

• Disperse load stress, reduce uneven settlement of roadbed, and prevent soil erosion.
• Enhance the anti-sliding ability of slopes, and reduce soil pressure by 30%-50% when applied to retaining walls.

2. Durability and adaptability

• Temperature resistance range -70℃~180℃, UV resistance, corrosion resistance, and service life of more than 50 years.
• Suitable for complex geology such as soft soil foundation, high fill, and wind-blown sand roadbed.

3. Economic benefits

• Reduce the thickness of the cushion layer by 36%, shorten the construction period, and reduce maintenance costs.
• The anti-settlement effect is several times higher than that of traditional two-way grids, extending the service life of the roadbed.

Typical application scenarios

Triaxial Geogrid Installation

Subgrade preparation

For roadbed where construction machinery cannot pass safely:

The three-axis geogrid shall be laid directly to the site to remove major projections such as rock, stumps and shrub piles, and fill local depressions and depressions with approved fillings, but retain the vegetation and topsoil covering the site.

Lay out the triaxial geogrid

Heavy gloves should be worn when handling the three-axis geogrid.

The three-axis geogrids can be laid either parallel to the road center line or horizontally on the roadbed.

If the geotextile partition is used with the triaxial geogrid, the triaxial geogrid

Must be laid over the geotextile (so that the laid filler can interlock with the pores of the triaxial geogriad).

lap

The lap width between the adjacent three-axis geogroidges depends on the grading and thickness of the packing

The stiffness of the roadbed. The minimum lap width shall be 300 mm and the maximum lap width shall usually be

600 mm, or as specified in the contract documents.

Llap must be fixed and maintained during filling. It is common practice to pile small piles of granular filling at the junction before the main filling operation begins.

Granular packing

The graded aggregate filler is suitable for unbonded granular packing.

We offer a variety of triaxial geogids with different apersizes to ensure

Compatibility between aggregate and geogrid resulting enabling efficient interlocking.
