CONSTRUCTION OF THIRD RAILWAY BRIDGE ACROSS RIVER GODAVARI

This paper describes the construction of a third railway bridge across the Godavari river. The substructure of the bridge consists of 29 wells and the structure is designed to the revised Railway Standards broad gauge loading of 1975. It also describes how artificial islands were formed to placement of cutting edges and concreting of the foundations. These artificial islands were formed either as sand islands or as sand bar-cum-islands. Construction of the substructure needed various specialised operations such as fabrication of cutting edges and placement, casting of well curbs and its grounding, steining concreting, and the sinking of wells etc. The paper also describes the construction of the caisson for pier No. 2. This includes a description of the grounding of the caisson and the plugging of the top and bottom, and sand filling. The paper also highlights the saving of the order of Rs. 82.00 lakhs in the cost of the work by using the technique of sinking the wells with dewatering, chiselling and pneumatic drilling process using divers. This procedure has also resulted in considerable saving in construction time. For the covering abstract see IRRD 860938.
