| Abstract: | Rectangular pipe-jacking machine is applied mainly in the underground tunnels of urban busy streets with the buried depth of 4-6 m. Taking a project for example, several construction conditions are put forward including meeting with large diameter & high strength rock, the intermediate well design, foundation pit bracing, excavation, obstacle clearing and the top of pipe-jacking machine mending. The construction experience can provide reference for the colleague. |
