Abstract

PURPOSE:To execute safely and easily underground work for connecting tunnels. CONSTITUTION:While cutters are provided to a shield machine 1 on one side so that the cutters can be projected and retracted, and expanded and contracted freely, a hood 10 is also provided to said shield machine, and a shield machine 21 on the other side can be attached to and detached from the hood 10 freely. Thereby, the two shield machines 1 and 21 can be connected without the need for providing a connecting device to the shield machine 21. Freezing pipes and injection pipes are provided to the hood 10. Works for connecting tunnels underground can be executed safely and easily with soil improvement in the connecting part executed without requiring execution of large-size construction work.
