The Construction Method of Non-excavation tunnel what used easy excavation method of Steel pipe and Deckplate

摘要

The present invention relates to a non-excavation tunnel construction method using an easy excavation method using a steel pipe and a deck plate, capable of reducing a construction period and construction costs. According to the present invention, the non-excavation tunnel construction method using an easy excavation method using a steel pipe and a deck plate comprises: a step (S10) of propelling and installing a plurality of horizontal steel pipes with a conical steel and a downward curved steel propelled in a coffer, and a deck plate inserted into the conical steel; steps (S20, S30) of installing a roller-typed moving device; a step (S40) of installing a return base and a reaction force plate; a step (S60) of excavating an upper half inside a leading structure of a towed rahmen shape and recovering an inner slip plate; a step (S70) of installing a strut and a lower slab; and a finishing step (S80) of filling cement milk in the conical steel, finishing various kinds of inner facilities, and performing asphalt pavement.
