Abstract

Abstract:

Individual construction machine could not meet the construction requirements of underground diaphragm wall under complex geological conditions in urban areas in China. The excavation effect of trench cutting machine with double milling cutters under complex or hard rock conditions is low. As a result, pipe roof drilling machine is used. The trench cutting effect is improved. The paper can provide references for retaining structure in urban areas of similar projects in future.

Key words: trench cutting machine with double milling cutters, pipe roof drilling machine, cooperating, Metro, retaining structure, underground diaphragm wall
