FOOTBRIDGE FOR EXTENSION AND RIVER CROSSING

摘要

Disclosed is a footbridge for extension and river crossing installed on the side of a road or a riverside having a slope for the passing of pedestrians or bicycles. The footbridge remarkably reduces construction time and costs by securing stability without the installation of a concrete structure and auxiliary support piles for supporting a steel coping bracket and minimizes damage to natural environment by not requiring an excavation work. Also, the footbridge prevents construction errors, such as an eccentric phenomenon generated when the steel coping bracket is installed and the over-cutting of piles, by not requiring a pile head cutting work for controlling the heights of the piles.
