壹探轨道|为泉水让路！解码济南地铁4号线“最浅车站”

Core Viewpoint - The construction of the泉城公园站 (Spring City Park Station) in Jinan is a significant engineering achievement that prioritizes the protection of the city's sensitive underground spring water resources while advancing urban transit infrastructure. Group 1: Engineering Challenges and Solutions - The泉城公园站 is located directly south of the famous趵突泉 (Baotu Spring) and conventional construction methods would disrupt the aquifer, necessitating innovative solutions [4] - The decision was made to "give way to the spring water," leading to the innovative "avoidance and elevation" strategy, which raised the station by 6 to 7 meters, keeping the maximum depth under 15 meters [6] - This elevation allows the station to be the shallowest on the line and the only "semi-underground" station, effectively avoiding the sensitive spring water area [7] Group 2: Environmental Protection Measures - The project employs "in-situ groundwater purification and reinjection technology," achieving a 90% reinjection rate of extracted groundwater back to its original aquifer, minimizing construction impact on groundwater [9] - A sophisticated underground water diversion system was installed to ensure the natural connectivity of the groundwater system during construction [10] - Special construction materials were developed to prevent contamination of groundwater, including "water-rich stratum anti-dispersion synchronous grouting materials" and "green sealing materials for karst dynamic water" [11] Group 3: Aesthetic and Structural Design - The station's design features a lightweight, flowing structure with a hyperbolic thin-shell reinforced concrete and continuous arch entrances, blending seamlessly with the surrounding natural landscape [11]
