  5. Gravity retaining wall construction with StrataWeb®

LOCATION

Near Gali Anjaneya Temple, Bengaluru, India

Client

Bruhat Bengaluru Mahanagara Palike

Product used

StrataWeb®

Application

StrataWeb® used for Gravity retaining wall for bridge approaches and road formation

About the project

The approaches to the bridge were to be constructed within a short time frame and amid traffic congestion. A concrete retaining structure would have required space for its construction. Besides, the construction of conventional concrete retaining structures would have resulted in time over-runs.

It was decided to construct the retaining structures of the approach ramps using StrataWeb® geocells for better economy, speed and ease and convenience of construction in the congested environment.

SW356-150 was used for the mentioned project. The StrataWeb® panels are stacked atop each other. Soil or aggregate was in-filled within the geocells as the panels are stacked. The panels were also placed such that there is a progressive backward batter. Gravity retaining walls constructed using StrataWeb® have a reasonable degree of flexibility that allows them to be constructed over foundation soils, which are non-uniform along the length, and there are possibilities of large differential settlements.

 

The provided system turned out to be a robust system due to the technical advantages of the products. The perforated structure of StrataWeb® served as free-draining weep holes to completely relieve the build-up of hydro-static pressures essential for safe design.
