  Study on chamber pressure and slurry level of mixed shield by prototype test

  Abstract: Nowadays, more precise control method on face pressure of slurry shield is beingadopted, combining air pressure control at the upper part of an air chamber with conventional slurry flow control. To grasp the feature and the control method of the air combined system, a prototype test was carried out using the model, which is composed of a cutter chamber, an air chamber, a slurry circulation...
