Pillar reinforcement technology does not require surface chipping and anchor drilling.
Slab reinforcement technology effectively reinforces with non-adherence method
This is a T-shape beam reinforce-ment technology that reinforces the shear strengthening steel to above the neutral axis
The central pillar was removed to maximally expand the central space, then the surrounding pillars were reinforced
The non-vibrating rock crushing technology crushes without noise or vibration with specially made hydraulic jacking device
Most of the existing methods uses installation of strut and using the strut to push, but Korea E&C's technology pulls from each side to improve construction and cost.
The foot crossing (45mx68m) at KTX Suseo station had original height plan of 4.8m. Because the passing was underground on first floor, the height was increased from 4.8m to 7.8m (3m increase) considering the exterior of the building.
4.8m -> 7.8m raise
Pillar cut, after 3m raise
