Wuhan Metro Line Railway Village Station Construction Safety Testing Machine

Traffic congestion, travel difficulties, has become a troubled life of the people of China and constraints of urban development is a major challenge to address the growing problem of urban traffic congestion, the city of more than million people, have turned to the development of subway and light rail transport system.In the new century, with economic development, reform and opening up, in the land of China, many major cities to speed up the pace of construction of the subway. In order to alleviate urban traffic congestion, Beijing, Shanghai, Tianjin, Guangzhou, four mega-cities not only in the continued construction of the MTR, but also to re-planning of urban rail transport blueprint, in order to facilitate the development of the city and extension of the new century. To the end of 2002, subway and light rail mileage has reached 228.94km. Nanjing, Shenzhen, Wuhan has started construction of the MTR, Chongqing is building a cross-Monorail traffic.Foundation is the basis for MTRC and all construction in the process of a traditional subject, with the rapid growth of China and the athletic continuous development of urban construction, high-rise buildings, subways, underground garage, underground mall and other projects in the increasingly deep excavation increased, and to continue to the direction of a large and deep, deep foundation construction, and construction monitoring support more and more attention, but also with deep excavation and development of urban high-rise buildings and underground space utilization more and more common.The traditional support is relatively simple, such as excavation and grading stakes envelope so simple. But the depth of deep foundation pit, not wide around the site, soil and bad, support can not meet these construction requirements. In recent years, with the pit depth and volume increased, supporting technology has made great progress, divided by function:retaining wall systems, retaining systems and support systems. Currently often used in deep excavation techniques are:steel sheet pile support, deep mixing support, supporting piles, diaphragm walls, soil nailing and composite soil nailing, anchor bolts and spray, Reversed Reversed and support, arch support and so on.Monitoring the process of subway construction has become a subway station an important part of the construction pit.This article describes the Wuhan Metro Rail Transit Line 4 iron machine Village Station a safety inspection program works and excavation of the foundation maintenance program.
