Abstract

The mechanical shield docking is a system where a cutter face of one shield machine is fit into skin plate of another shield machine of which cutter face is gone back. The cut off of water is performed with two seals which are tube seal and sand seal. Test construction of the mechanical shield docking was conducted at the arrival shaft of Yazawagawa shield project for Tokyo Metropolitan Government Bureau of Sewerage.
From the test results, it was found that the amount of water leakage was less than 2.5l/min and this mechanical shield docking showed a good performance.
