Yingyuan Sponge City Elevates Shanghai-Wuhan Expressway Changzhou Section to a Green Smart Transportation Benchmark

Project Overview

As a vital national trunk artery linking Shanghai and Wuhan, the Changzhou Section handles an average daily traffic volume exceeding 50,000 vehicles, imposing stringent requirements for drainage safety and ecological stewardship. Aligned with national sponge city construction standards, the project establishes a holistic "source reduction-process control-end reuse" rainwater management framework. Treated rainwater is repurposed for green belt irrigation, road surface cleaning and service area maintenance, delivering dual benefits of municipal water conservation and reduced pollutant discharge into adjacent water bodies. 

Customized Engineering Solution

To address the expressway’s unique challenges of heavy traffic loads, deep overburden and complex rainwater composition, Yingyuan’s technical team engineered a solution centered on the Hurricane HD national-standard heavy-duty rainwater module following rigorous on-site surveys and mechanical simulations. Boasting a positive pressure capacity exceeding 45 tons, lateral pressure resistance over 15 tons and support for up to 3 meters of overburden, it safely withstands continuous heavy truck traffic. The water treatment system employs a "interception & abandonment + sand filter + UV disinfection" process to ensure compliant effluent quality, integrated with an intelligent control platform for real-time monitoring and fully automated operation. 

Distinct Project Advantages

Outperforming traditional concrete reservoirs, Yingyuan’s PP module system delivers three transformative benefits: First, unmatched structural integrity that eliminates collapse risks entirely. Second, accelerated construction with factory prefabrication and on-site modular assembly, completing all installation and commissioning in just 15 days to safeguard the expressway’s opening schedule. Third, streamlined maintenance with a 92%+ void ratio for maximum storage efficiency and an open design enabling fully automated cleaning and inspection.
