<p>The present invention relates to a construction method of a column-shaped center wall in two arch underground tunnels to carry out a construction of the center wall which is a center of an underground tunnel. More specifically, the construction method of the column-shaped center wall in two arch underground tunnels using a column mold is a construction method using a column mold to enable to move on to the next step of forming an integrated column mold of a steel sheet, setting the mold, and breaking the mold away entirely after the concrete cast-in-place; in order to simultaneously solidify concrete by constructing an arch central part, which is a part where an arch ceiling is overlapped to each other, and the column-shaped center wall to support the ceiling when the underground tunnel of an arched structure is formed in a pair.</p> |
