July 1 update – Wuhu Longwan Yangtze River Tunnel, Anhui’s inaugural cross-Yangtze passage, officially opened today.
Project Vital Stats
North entrance: Jiangbei New District, Longwan Road
South exit: Yijiang District, Dagongshan Road
Structure: Twin-tube, 6-lane urban expressway
Length: 5.65 km
Design speed: 80 km/h
Impact: Reduces cross-river commute from 40 mins to 5 mins, accelerating regional integration into Yangtze River Delta.
Engineering Feats
Operating at 68m below river level – the Yangtze’s most geologically challenging tunnel – it conquered:
➤ Extreme hydrostatic pressure
➤ Complex stratigraphic control
➤ High-risk fault crossings
➤ Subsurface methane pockets
Conch’s Critical Role
Baimashan Cement Plant supplied 140,000+ tons of specialized cement, including:
✓ PI 52.5-grade cement for tunnel segments – forming subaqueous "armor" with unmatched strength and durability
✓ Foundation pile concrete with superior workability and compatibility
✓ High-resistance aggregates for wind towers’ structural skeletons
Precision Supply Chain
Baimashan executed:
☑ Rigorous material screening
☑ Real-time quality monitoring
☑ Customized technical support
☑ Coordination with 12 construction stakeholders
Urban Legacy
From bridges (Guanhu 1st/2nd/3rd) to infrastructure (Wuxuan Expressway, Wuhu Rail Station, Light Rail, Xuancheng Airport), Conch cement has underpinned Wuhu’s metamorphosis into a regional hub.
Final Salute
To the 50,000+ Conch builders who made this possible:
"Tunneling through mighty waters, we carve prosperity beneath the waves. Wuhu – SOAR!"
