Khai Dinh Highway Bridge
A better alternative choice
A reinforced soil structure with concrete facing panels was constructed as a bridge approach for Khai Dinh bridge in Thua Thien Hue Province, Vietnam. Tensar RE uniaxial geogrid was used to reinforce the retaining structure instead of the inextensible steel reinforcement.
Benefits:
- Easy installation with a concrete panel facing
- Rapid construction using a small plant and equipment
- Cost effective solution using HDPE Tensar uniaxial geogrid instead of inextensible steel reinforcement
Khai Ding Bridge is part of THE XL10 construction package of the Cam Lo - La Son section, which passes through Thua Thien Hue and Quang Tri Province. The package consists of the construction of a reinforced soil structure, featuring a maximum height of 10m. As the bridge is located in the vicinity of a residential area, small machineries and equipments were preferred to minimise traffic disruptions.
Tensar uniaxial geogrids were used to replace steel reinforcement for the bridge approach retaining structure construction in Khai Dinh Bridge project. Geogrid tabs were casted into the 1.0m x 1.2m x 0.2m thick concrete panel with minimum 65mm embedment and connected at site to design length using bodkin connection. The length of the structure is 41m long with maximum height of the wall of 10m.
