초록
A pipe jacking method complements the excavation method and it is a non-excavation method which is thrust in the earth. On that score, using the pipe jacking method is increased because of constructability and economical efficiency in a medium or small-sized pipeline construction. However, a pipe jacking method still has several problems that the base ground is disturbed and loosen. Especially, where some sites have boulders, gravels and foreign bodies, the foundation is brought about deformation, settlement and leakage of water. Thus, the end of the construction the ground should be reinforced by grouting and it occur with additional expenses. Therefore, a steel pipe jacking method with grouting, Grout In Pipe, is devised newly to complement the existing method. In this study, it describes a new method and verifies efficiency, an application and practicality of the method through a experimental construction.
