<p>The present invention relates to a dual segmented precast concrete arch system and a fabrication method thereof for fabricating a dual segmented precast concrete arch tunnel or bridge. And more specifically, a dual segmented reinforced concrete arch member segment main body is transferred to a site and constructed on a foundation prepared in advance, and a reinforcing rod is arranged in a joint part of an arch ceiling portion, and strongly joined by concrete casting. The amount of the cast-in-place concrete is drastically reduced by reducing the width of a cast-in-place joint, and the assembly construction is facilitated. Moreover, economical efficiency can be improved since a structural system which temporarily supports the arch segment main body is improved.</p> |
