Suspension bridge in 1,000 m height on Gubong Mountain, South Korea

Gubong Mountain in the southern province of Jeollabuk-do in South Korea is a popular destination that draws an ever increasing number of tourists. Some of the hiking trails leading to the different peaks of the Gubong Massif traverse very steep and dangerous sections. In order to increase safety for tourists, the province's department of administration decided to build several safe ropes, steel stairways, observation platforms and bridges connecting the individual peaks.

A pedestrian suspension bridge that was built between two peaks is part of this project. To tie back the support cables at the abutments of the bridge, DSI Korea supplied 24 double corrosion protected, 32 mm and 40 mm Ø, 10 m long DYWIDAG THREADBAR® Anchors.

In addition to the two supporting cables, the suspension bridge is secured by two additional wind cables that were tied back in the foundations underneath the bridge in the load bearing rock. The two wind cables, which run parallel to the bridge deck underneath the suspension bridge, are braced multiple times upwards toward the bridge deck. Using this method, the suspension bridge is effectively stabilized against possible vibrations due to high wind speeds.

Equipment and anchors had to be transported by helicopter

Because of the difficult accessibility of the construction site located at a height of 1,000 m, both the equipment needed for tensioning the DYWIDAG THREADBAR® Anchors and the anchors themselves had to be transported to the jobsite individually by helicopter.
