上海轨道交通十一号线北段二期GT-15标质量管理体系总则及工程概况

Shanghai Metro's Quality Management System documents for the construction project of the northern section of Line 11 Phase II GT-15 outline the basic overview of the project, including the scope and scale of the engineering works. The project spans from the middle vent of Huashan Road to Luoshan Road Station, passing through the Xuhui and Pudong districts. The route covers approximately 22.886km with 13 stations and a parking lot. The rail structure consists of different types of track systems based on the location - underground sections use DTIII2 type fastenings with long sleeper embedded steel-reinforced concrete track beds, elevated sections use WJ-2A improved type fastenings with longitudinal support rails and short sleeper steel-reinforced concrete track beds, and surface sections use Type I fastenings with new Type II prestressed concrete sleeper gravel track beds. Various vibration mitigation techniques are used in different sections including LORD fastenings, track dampers, steel spring floating plate tracks, and special floating plate tracks. Turnouts include single-slip, triple-slip, single-crossover, and crossover tracks with foundation track beds. The Chuan Yang River Parking Lot is located in the southeast corner of Huaxia Middle Road and Luoshan Road in Pudong New Area, with the site planned to be on the northern side of Yuchiao Road and west of the maglev line. The irregular rectangular site is approximately 1500 x 5 in size and is designed to accommodate the parking needs for the project. In conclusion, the detailed quality management system documents for the Shanghai Metro's Line 11 Phase II GT-15 construction project provide a comprehensive overview of the engineering works, track structures, and associated facilities. The project aims to deliver a high-quality rail system that meets the standards of safety, efficiency, and sustainability required for modern urban transportation.
