PROBLEM TO BE SOLVED: To provide a construction method for reinforcing the natural ground, attaining the adequate improvement and reinforcement of the natural ground without needing to provide a widened cross section area and executable at a low cost in various excavating methods. SOLUTION: In this construction method for reinforcing the natural ground, a plurality of pipes with discharge holes bored in the peripheral walls are driven in the natural ground at a specified elevation angle while being successively connected to form a reinforcing pipe comprising a plurality of connected pipes, and a solidifying material is filled through the reinforcing pipe to form a consolidated area in the natural ground around the reinforcing pipe. A part positioned at the mouth part of the reinforcing pipe is formed by connecting a plurality of short steel pipes through a joint means such as an easily separated coupler. As the natural ground is bored, parts exposed from the natural ground are successively separated from the reinforcing pipe by the connected short pipes.
