Bridges over Zuari and Mandovi River – Bearing Replacement Work Under Tight Schedule

In the case of the project to replace the bearings of the main span structures of two railway bridges in western India – on the Zuari and Mandovi rivers – a major challenge was presented by the severely limited track closures during which work could be carried out (maximum 3 hours, sometimes only 1.5 hours). Another significant challenge was the difficult access to the pier tops. After evaluating the situation in detail, mageba proposed a complete solution involving the design and manufacture of suitably dimensioned and detailed RESTON® POT bearings, the construction of a temporary access platform at each pier to facilitate the installation work, lifting of the bridge superstructures using specially designed low-height hydraulic jacks, and injection of rapid-cure grout beneath the new bearings to ensure proper transfer of load to the substructures.
