Application of EPB Jacking Pipe in DN 2400 Pipeline

Earth pressure balance pipe jacking technology, it can be safely used for soil as shallow as 0. 8 times of OD. The authors introduced Huanggang Yi-ai Lake interception in dredging DN 2400 pipeline -test section (158m) of earth pressure balance pipe jacking successful practice. Through cases, adverse geological conditions of large diameter earth pressure balance pipe jacking technologies such as ground deformation control issues to explore. At present there is not yet the successful practice of the project in China. The success of this case will help to promote the construction of earth pressure balance pipe jacking technology, innovation and progress, for future similar projects with some guidance.
