High Tension Resistance, High Plane Torsion Resistance Modulus, Good Creep Resistance PP Biaxial Plastic Geogrid

Biaxial Plastic Geogrid Introduction

Biaxial geogrid is made of polymer through extrusion, forming plate, punching process, and then longitudinal and transverse stretching. The material has great tensile strength in both longitudinal and transverse directions. This kind of structure can also provide a more effective chain system for bearing and diffusing force in soil, which is suitable for foundation reinforcement with large area permanent bearing.

Biaxial Plastic Geogrid Specification

Biaxial Plastic Geogrid  features

1. Increase the bearing capacity of subgrade and prolong its service life.
2. Prevent the road (ground) surface from collapse or crack, and keep the ground beautiful and tidy.
3. Convenient construction, time-saving, labor-saving, shorten the construction period, reduce maintenance costs.
4. Prevent cracks in culvert.
5. Strengthen soil slope to prevent soil erosion.
6. Reduce the thickness of cushion and save the cost.
7. Support the stability of slope grass mat greening environment.
8. It can replace the metal net and be used in the false roof net of coal mine.

 Biaxial Plastic Geogrid Application

1. Subgrade reinforcement of various highways, railways and airports;

2. The foundation of permanent bearing such as large parking lot and wharf freight yard is strengthened;

3. The protection of culvert and highway slope should be strengthened;

4. The soil slope reinforced by unidirectional tensile geogrid is strengthened twice to further strengthen the soil slope and prevent soil erosion;

5. Mine and tunnel reinforcement.

Biaxial Plastic Geogrid Construction Method

Excavate the foundation bed, set sand cushion (height difference is no more than 10cm), roll it into platform, and lay grid. The longitudinal axis should be consistent with the main stress direction, and the longitudinal overlap should be 15-20cm and horizontal 10cm. The lap joint should be bound with plastic tape, and fixed on the ground with U-shaped nails every 1.5-2m on the laid grid. The laid geogrid should be backfilled in time. The number of layers of geogrid laid depends on the technical requirements .
