The role of geogrid is provided
1. Reinforcement and enhancement effect
Improve the bearing capacity of the soil. The interaction between the geogrid and the soil particles can effectively increase the cohesion and friction of the soil, thus improving the bearing capacity of the soil, so that it can withstand a greater external load.
Enhance the stability of the foundation. In the treatment of soft land foundation, laying geogrid can effectively disperse the load from the superstructure, reduce the settlement and uneven settlement of the foundation, and improve the stability of the foundation.
Reinforcement slope. For the filled slope or the excavated slope, the geogrid can enhance the tensile strength of the slope soil, prevent the slope collapse and landslide, and improve the stability of the slope
2. Anti crack action
Reduce the generation of road surface cracks. In road engineering, geogrid can effectively reduce the cracks caused by temperature changes, traffic load and other factors, and improve the service life of the road surface and driving comfort.
Prevent the expansion of the reflection crack. For the old road reconstruction project, geogrid can effectively prevent the cracks of the old road from reflecting on the new road surface and reduce the maintenance cost of the road.
3. Drainage effect
Promote the discharge of water from the soil. Geogrid has a certain porosity, which can form a drainage channel in the soil, promote the discharge of water in the soil, reduce the water content of the soil, and improve the stability of the soil.
Prevent water damage to the engineering structure. In water conservancy projects, geogrid can effectively prevent the damage of water to the dam, revetment and other engineering structures, and improve the safety of the project.
4. buffer action
Prevent different properties of the soil material mixed. Geogrid can effectively isolate the soil of different particle sizes and different materials, maintain their own engineering characteristics, and ensure the stability of the engineering structure.
Avoid mutual contamination between adjacent materials. In road engineering, geogrid can prevent the contamination of subgrade soil and pavement materials, and ensure the performance and life of the road surface.
5. safety action
Prevent the soil from being damaged by external forces. Geogrid can resist the destruction of natural forces such as water erosion and wind erosion, protect the surface of the soil, and prolong the service life of the project.
Protect the engineering structures. In some special projects, such as tunnels, pipes, the geogrid can protect the structures from the external environment.
