HULL PROPULSION METHOD USING GUIDE-SHAPED STEEL

摘要

The present invention relates to a hull propulsion method using guide-shaped steel, which reinforces the ground by inserting a protective steel pipe, enables precise construction for an underground tunnel using the guide steel formed within a steel pipe and connected with a hull when a concrete hull is propelled, and can minimize an influence on the upper ground. The hull propulsion method comprises the steps of: a) constructing a propulsion base and an arrival base; b) forming a steel pipe composite according to construction locations of an outer wall and an upper slab in the hull; c) inserting the guide-shaped steel into the steel pipe composite; d) connecting an end of the guide-shaped steel to the hull when the hull is manufactured in the propulsion base; e) propelling the hull; f) releasing the hull and the end of the guide-shaped steel from each other; and g) filling mortar between an outer surface of the hull and an inner surface of the steel pipe.
