On May 21st, MCC SKET commenced the Shenyang Metro Line 4 Phase I Civil Engineering Project.
This project consists of one section and one station. Wanghuatun Station has two underground floors, a total area of 14,735.86 m2, a two-storey three-span island-type platform major structure, a total length of 296.05 m and an effective platform width of 14 m. The standard section has a width of 22.7 m. The soil on the roof is about 3.0 m in depth. The baseboard of the station is buried to a depth of about 16.45 m. The station uses the open excavation order method. The building envelope of the standard section adopts a support and protection system consisting of bored piles, three-steel support and one change support. The shield shaft expansion section adopts a support and protection system consisting of bored piles, four-steel support and one change support. The enclosing piles of the major structure are bored piles with a total footage of 14,075 m.
Expected to be completed in 2020, Metro Line 4 mainly passes by such important public transport junctions as Shenyang North Station and New Shenyang Station, such commercial areas as Shenyang North Station and Taiyuan Street, such residential areas as Wanghua and Shashan, and such educational and industrial areas as Shenyang University and Hunan Industrial Area. The whole line has a length of 34.132 km and allows transfer among other metro lines.
