Shanghai's Record Breaker

This article describes the use of highly advanced Tunnel Boring Machines (TBM) for use in the twin bore in the current drive beneath Shanghai’s Yangtze River to the island of Changxing, which currently is only connected to the mainland by ferry. Each tunnel will be split into two decks, with the upper section providing three lanes of traffic each and the lower to support a future metro line extension. While the geology of the area is not particularly bad for such excavations as it is mostly sand, clay, and fractured rock, there is a rather high groundwater pressure that adds complexity to the process. The assembly of the TBM took about a year and a half, as parts needed to be shipped to China from Germany in stages. Other complexities with the project that are listed herein are excessive amounts of spoil and transporting of precast concrete segments.
