Construction method used for underground tube construction method and pipe guide device used for its construction method

摘要

In the present invention, when the pipe is hydraulically pressed into the underground, a guide beam having a strong strength is first inserted into the ground, and then the pipes are inserted and installed to move along the guide beam. It is to provide an underground insertion type pipe construction method and a pipe guide device used in the construction method so that the insertion end portion can be inserted in a straight direction without bending while pushing the rock or the big stone even when the rock tip or the big stone is in contact.
