Hunan steel-plastic geogrids can effectively lower groundwater levels.
Release date:
2020-12-08
Freeze damage causes cracks to form on the road surface. When roads are in this condition, heavy vehicles passing over them can significantly increase tensile stresses at the bottom of the asphalt concrete pavement or cement concrete slabs. At the same time, vertical deformations at the subgrade surface also intensify. If these stresses exceed the material’s limit, network-like cracks begin to develop along the wheel tracks, leading to further road subsidence and eventual structural failure.
To prevent frost damage, the main measures involve lowering the groundwater level and improving drainage in the roadbed. Hunan Chenzhou Steel-Plastic Geogrid Constructing seepage trenches effectively lowers the groundwater level. Hunan Chenzhou Steel-Plastic Geogrid It is a semi-rigid product made by weaving high-strength, alkali-free glass fibers into a mesh-like substrate using ShiJieLing's advanced warp-knitting technology, followed by a surface coating process. This material exhibits exceptionally high tensile strength in both the warp and weft directions, along with low elongation, while also offering outstanding performance characteristics such as resistance to high temperatures, extreme cold, aging, and corrosion. As a result, it is widely used for reinforcing asphalt and cement pavements, enhancing roadbeds, and supporting critical infrastructure projects like railway subgrades, dam embankment slope protection, airport runways, and sand-control initiatives.
Meanwhile, Hunan Chenzhou Steel-Plastic Geogrid The separation and drainage functions within the roadbed interrupt capillary action, which normally drives water movement through the soil. This is especially critical during freezing, as it prevents water from accumulating in the frozen zone—thus avoiding frost heave altogether. And when spring thaw arrives, the steel-plastic geogrids used in Chenzhou, Hunan, effectively block soil particles from being carried upward with the flowing moisture, thereby preventing the formation of slush heaving.
Hunan Chenzhou Steel-Plastic Geogrid Fang's approach to addressing track ballast upheaval and mud-jacking primarily focuses on improving drainage in the ballast bed. Traditionally, this has been achieved by laying a sand cushion layer between the subgrade and the ballast, which enhances drainage from the subgrade and helps distribute the dynamic stresses transmitted from the crushed stone ballast evenly across the subgrade. This process reduces both the impact forces and stress concentrations that can lead to ballast crushing, thereby minimizing track upheaval and mud-jacking. However, as traffic volumes continue to rise, issues often re-emerge in areas where sand cushions were initially used. Such conditions can degrade track quality, increase the frequency of routine maintenance and repairs, and, in severe cases, even compromise train speeds and operational safety. To address these challenges in soft soil foundations, steel-plastic composite geogrids are increasingly employed for reinforcement. Their mesh-like structure significantly improves drainage within the soft soil, allowing water to escape more effectively under the load of embankment fill. As a result, the soft soil undergoes consolidation, leading to enhanced soil strength and increased bearing capacity of the foundation. Moreover, when combined with the soft soil, the steel-plastic geogrid forms an interlocking system. Under vehicle loads, this system redistributes vertical stresses more uniformly across the foundation, further stabilizing the track structure and reducing the risk of uneven settlement or deformation.
