Composite shield construction method
Shield tunneling method that allows for the selection of the face stability mechanism according to ground conditions.
The "Composite Shield Method" is a shield that has a mechanism allowing for the selection of the face stability method according to the conditions of the ground. With a single shield, for ground conditions suitable for earth pressure type shields, stability of the face can be achieved using plastic fluidized excavated soil within the chamber, and for ground conditions suitable for slurry type shields, stability of the face can be achieved using slurry, making it a shield with a wide range of adaptability to ground conditions. 【Features】 ■ A single shield can select a face stability mechanism that corresponds to the soil conditions. ■ In gravel ground, gravel can be directly crushed by a crusher, enabling fluid transport. *For more details, please download the PDF or contact us.
