An embodiment of the present invention relates to a method for constructing an underground structure. The technical purpose is to provide the method for constructing the underground structure capable of easily press-fitting steel pipes and reducing a construction period and construction costs by installing small-diameter steel pipes underground first and installing large-diameter steel pipes and the underground structure constructed by the same. To achieve the same, the present invention includes: a first steel pipe press-fitting step of press-fitting multiple upper first steel pipes in a transverse direction in an upper part and press-fitting multiple lateral first steel pipes in both sides of the upper first steel pipes; a second steel pipe press-fitting step of press-fitting upper second steel pipes in an outer side of the upper first steel pipes and press-fitting lateral second steel pipes in an outer side of the lateral first steel pipes while allowing the lateral first steel pipes are positioned therein; a first steel pipe removing step of removing the upper first steel pipes inside the upper second steel pipes and removing the lateral second steel pipes inside the lateral second steel pipes; a reinforcing material installing step of installing a reinforcing material inside the upper second steel pipes and the lateral steel pipes; and a step of excavating soil in a region limited by the upper second steel pipes and the lateral second lateral pipes, installing aggregates and reinforcement in the upper second steel pipes and the lateral second steel pipes, and placing concrete. |
