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!"
