摘要： PROBLEM TO BE SOLVED: To provide a shield machine, the overall length of which can be kept short and which can resist the water and earth pressure of natural ground without the use of a solidification material such as high-strength mortar, and a working area forming method for the shield machine. SOLUTION: A soil-improved area R is formed by injecting a chemical solution into the excavation-direction front section of the shield machine 1. After that, a frozen area F is formed around the shield machine 1 in such a shape as to lap the area R. The earth pressure of the natural ground is mainly resisted by the area R of them, and the intrusion of the groundwater into the working area is prevented by the frozen area F and the area R.
