Underground Tunnel Development Survey of Shield Tunnelling Machine

Abstract

In this paper, the technology based on site investigation adequately, through reading, analysis and comprehensive vast literature of shield lining segments, installed spelling were analyzed, and the conclusion that some valuable conclusions. Summarizes the construction process of shield technology, and introduces the earth pressure balance type shield construction machine structure and working principle. Shield technology is with modern transportation, underground engineering, mining, water conservancy projects and municipal construction needs and developed advanced tunnel construction technology. With China's urban underground transportation facilities, the quickening of the process of shield technology has become the hotspot of domestic engineering.
