Abstract:

Appropriate cutters collocation and cutters inspection and replacement in long distance TBM boring is an important and difficult point of a project. With the Yellow River Crossing works of South-to-North Water Transfer Project, this thesis will discuss on the construction technology of foundation consolidation, water level dropping in deep ground, cutter head maintenance, cutter modification, etc adopted in entering earth cabin in deep ground with high water pressure.

Key words: shield atmospheric pressure, three axes mixing pile, water level dropping with vacuum, cutter support maintenance, cutter modification
