Foshan Metro Line 2 project, as the main artery of urban public transport, has very high quality requirements for its construction. Metro stations are mostly underground construction, and track bed construction is long along the line. The formwork installation, demolition and turnover are mostly carried by manual. Platinum gravel plastic formwork has been successfully applied in Suzhou Metro Line 1, Ningbo Metro Line 2, Foshan Metro Line 1, Shanghai Metro Line 11, Shanghai Songjiang Tramway and Suzhou Tramway with its portability, waterproof and high turnover times. It has brought great benefits to the quality of the project while ensuring the quality of the project. Economy.
