1 Introduction
The bidirectional plastic grid is made of * * * polymer through the process of extrusion, plate forming, punching, and then longitudinal and transverse stretching. This material has great tensile strength in both longitudinal and transverse directions, and this structure can also provide an ideal chain system for bearing and diffusing force in soil, which is suitable for foundation reinforcement of large area and long-term bearing.
As the * * * * of the polymer in the manufacture of the bidirectional plastic geogrid will be rearranged and oriented with the heating and extension process, the bonding force between the molecular chains is strengthened, and the purpose of improving its strength is achieved. Its elongation is only the original board Of. If the geogrid is added carbon black And other materials.
purpose
The two-way plastic grid is applicable to various embankments and subgrade reinforcement, slope protection, tunnel wall reinforcement, large-scale airports, parking lots, wharf freight yards and other long-term bearing foundation reinforcement.
1. The two-way plastic grille is used to increase the bearing capacity of the road (ground) foundation and extend the service life of the road (ground) foundation.
2. The two-way plastic grille is used to prevent the road (ground) surface from collapsing or cracking, and keep the ground beautiful and tidy.
3. The two-way plastic grille is used to facilitate construction, save time and labor, shorten the construction period and reduce maintenance costs.
4. The two-way plastic grille is used to prevent cracks in the culvert.
5. The two-way plastic grid is used to strengthen the soil slope and prevent water and soil loss.
6. The two-way plastic grille is used to reduce the thickness of cushion and save the cost.
7. The two-way plastic grid is used to support the stability of the slope grass planting mat for greening environment.
Construction method
When the two-way plastic grille is used for subgrade and pavement, the foundation bed shall be excavated and the sand cushion shall be set (the height difference shall not be greater than 10cm), rolled into a platform, and laid the geogrid. The longitudinal axis should be consistent with the main stress direction. The longitudinal overlap should be 15-20cm, and the transverse overlap should be 10cm. The overlap should be bound with plastic tape, and fixed to the ground with U-nails every 1.5-2m on the laid geogrid. The laid geogrid should be backfilled in time. The number of layers of laid geogrid depends on the technical requirements.
