Abstract

Abstract:

The construction difficulties of curved jacking pipe roofing of Gongbei Tunnel under complex soft soil, high groundwater pressure and sensitive environment conditions are analyzed. The technologies adopted include pipe jacking machine selection, launching and receiving under high groundwater pressure technology, accuracy control of small span curved jacking, pipeline structure and sealing test and treatment of pipe jacking slurry and obstacles. Good effects have been achieved.

Key words: Gongbei Tunnel, curved jacking pipe roofing, accuracy control, steel sleeve receiving chamber, pipe jacking slurry, relay sleeve method
