Construction Technology of Shallow Pipe- Jacking Working Shaft

Abstract:

During the pipe jacking construction, the bearing plates of jack need the support of great reactive force which is provided by the side-wall of the working shaft and the soil mass behind the wall. In the shallow pipe-jacking working shaft, the soil mass only can provide limited reactive force due to the small height of the soil mass behind the side-wall, which becomes the difficult point in the design and construction of the shallow pipe-jacking working shaft. This thesis takes the actual projects for the examples to introduce the construction technology of shallow pipe-jacking working shaft in details, including the construction key points like pre-grouting injection consolidation, ring beam construction method as well as reverse construction method.
