| Abstract: | At the present time,the main issues in pipe jacking are the analyses and calculation of feeding resistance during pipe jacking,the soil movement in shallow pipe jacking,the friction-reduction mechanism of grouting in long distance pipe jacking,as well as curvature radius in curve pipe jacking.This paper takes some treatment measures and obtains better effect,by integrating the practice of the pipe jacking construction of the secondary pipeline of the main urban drainage D trunk in Chongqing. |
