 ABSTRACT

In the process of shield construction of TIANJIN metro line5, diaphragm wall of the Cultural Center transportations hub needs cross, view of the shield machine tool wear crossing the concrete structure, blasting construction method was used. Combined with the characteristics of the construction of Cultural Center on Tianjin Metro Line5, underground blasting construction technology and implementation effects were introduced, construction technology features of diaphragm wall and construction process were detailed analyzed , these as reference for similar projects.

Keywords: Metro, Diaphragm wall, Blasting, Construction
