Why should the working chamber be set behind the digging chamber when the slurry shield machine is working?
The same slurry shield, the working principle is not the same.
Germany's slurry shield, the cabin is a passive pressure regulation, that is, the pressure of the air cushion cabin to adjust the mud pressure of the excavation chamber. The Japanese shield usually does not have this bin, and he builds the pressure on the mine by the mud pump. Hope to be of help to you.
Probably divided into the European and Japanese systems. The warehouse you are talking about is a European or German system called an air cushion, with gas at the top and mud underneath.
