A Chinese firm this week rolled off the largest-ever shield tunneling machine for export, which is destined for Bangladesh to assist with a river tunneling project.
The export of the machine made by a manufacturing company based in east China’s Jiangsu Province will break the monopoly of ultra-large tunneling equipment by ‘developed’countries in exports, according to Zhou Jun, chief engineer with the Chinese firm.
The machine with a diameter of 12.12 meters weighs 2,200 tonnes. It will be used for opening a 3,500-meter road tunnel under Karnaphuli River.
