Reinforced Earth Retaining Wall Project for Municipal Slope (Warp-knitted Polyester Geogrid)
Reinforced Earth Retaining Wall Project for Municipal Slope (Warp-knitted Polyester Geogrid)
Project Overview
This project is a high slope of municipal road in a new urban area. Due to limited construction space, a reinforced earth retaining wall structure was adopted for slope reinforcement.
Project Pain Points
The high slope generates large lateral soil thrust. Conventional geosynthetics are prone to creep deformation under long-term load, which may cause displacement and instability of the retaining wall in the later service period. The project requires high-stability, low-creep reinforcement materials for long-term slope safety.
Selected Product
Uniaxial warp-knitted polyester geogrid with a tensile strength of 150kN/m.
Construction Scheme
The geogrid is laid horizontally in layers. One end of each geogrid layer is firmly anchored to the retaining wall panel, followed by layered backfilling and compaction of soil to form an integral reinforced earth structure.
Implementation Effect
Benefiting from the excellent low-creep performance of PET geogrid, the structure produces negligible deformation under long-term soil load. The safety factor of slope stability reaches above 1.5. The solution effectively saves land occupation and reduces the overall project cost compared with traditional masonry retaining walls.
