SCOPE OF WORK:
Meghna Bridge, situated on a 25 km stretch of Dhaka-Chittagong Highway (NH1) is a pre-stressed concrete bridge with central hinges that opened for traffic in 1991. Abnormal vibration and sound were noticed in Meghna Bridge during the passage of heavy vehicles over it. Investigation revealed that the central hinge bearings and expansion joint of Meghna Bridge were damaged. We accepted the project for rehabilitation.
DESCRIPTION OF WORK:
The rehabilitation work of the 930 meter-long Meghna Bridge & 1410 meter long Gumti Bridge involved the permanent solution of 96 fully damaged hinge bearings with the import of bearings from Malaysia.
The Challenges
No maintenance was carried out after the construction of the bridge. We had to invest a lot of time and labor to unfasten the old damaged bearing before installing the new one by following an advanced technological method.
