Abstract

Abstract:

The disassembling of largediameter opentype TBM in tunnel has many difficulties and it is hard to be carried out. In this paper, the preparation and disassembling technologies for backup system and main body of Robbins TBM 335, used in XSQLS2 Bid Section of West Qinling tunnel on LanzhouChongqing Railway, are presented in detail. Meanwhile, some suggestions have been given.

Key words: West Qinling tunnel, largediameter opensype TBM, nondestructive disassembling, backup system, main body, main bearing
