ABSTRACT:
When carrying out replacement of an old main with a new one while crushing the old pipe line by a pipe jacking construction method in which the pipe line is formed by inserting pipes one by one horizontally from a launch pit without excavating the ground, application of low load is sufficient for forward movement of new main. Accordingly, a pipe for pipe jacking is able to endure to low load. Thus, there is provided an improved pipe for pipe jacking.
