This project consisted of work to repair existing bridges, and to build second parallel bridges alongside the existing ones, in Bangladesh. Impacted bridges were the Kanchpur Bridge, Meghna Bridge, and Gumti Bridge on the N1 national highway connecting the capital Dhaka with the country’s second city Chattogram. The purpose of this work was to help energise the overall economy in Bangladesh, with widening of the lanes, measures to prevent scouring of the piers, and improved earthquake resistance aimed at supporting increased traffic flows with improved safety.
Implant™ Method Adopted for Bridge Foundation Construction (ODA Project) in Bangladesh
Selection Basis
Employing unique tubular sheet pile well foundation structures from Japan, construction of the bridge foundations relied on the ability of GIKEN press-in technologies to construct the particularly difficult area under the bridge girders. Construction time was also minimised by using four SILENT PILER™ machines concurrently.
