The Shilong Overpass ramp on the north side of Fushi Road in Guangning Street, Shijingshan District, serves as the primary access route to the Beijing Winter Olympics Organizing Committee and represents the largest slope ecological restoration project in Beijing’s six urban districts. The scope includes green space mountain slopes around the overpass roundabout core area and green belts along both sides of the auxiliary road.
Technical Application
As a joint construction unit for this project, our company provided equal-strength self-permeable geocells to stabilize mountain slopes and enhance filling material stability. We adopted a geocell (vegetation) slope protection system combined with green vegetation spray seeding, addressing challenges such as steep gradients, difficult construction conditions, and uneven frame beam slope surfaces.
– Geocell Solution :
The self-permeable geocells created a structured framework to anchor slope soil, reducing erosion risks while allowing natural water infiltration. Their modular design conformed to irregular slope geometries, eliminating the need for extensive manual leveling of frame beams.
– Vegetation Spray Seeding :
By filling geocell cells with a mixture of local soil, nutrients, and drought-resistant grass seeds, we established a vegetative cover that stabilizes slopes biologically. This method reduced construction time by 30% compared to traditional concrete anchoring while achieving a 95% vegetation survival rate in the first growth cycle.
Project Impact
This initiative transformed a high-risk, barren slope into a green buffer zone, improving traffic safety for Olympic-related routes and enhancing urban ecological resilience. The innovative geocell-vegetation system not only met strict deadlines for the Winter Olympics but also set a benchmark for sustainable slope engineering in urban mountainous areas.
