| Abstract: | Combined with large diameter long-distance curved pipe-jacking construction of Shanghai sewage treatement projects, the reasons and the risk of long-distance curved pipe-jacking have been introduced in this paper. Through a case, the reasons of serious axis deviation are analyzed; the detailed measures and the process of correcting errors are presented. Finnally, the testing measures are proved to be effective and full of reference va- lues. |
