Clay clogging of a TBM cutterhead during boring has serious effects. For instance, it impedes the movement of the spoil in the cutting wheel, excavation and suction inlet area. Clogging may even completely stop the flow of materials. Clogging often starts either with buildup in the suction inlet area or with buildup in the rear working chamber. Clogging potential was defined as the interaction of four mechanisms: adhesion of clay particles on a component surface, bridging of clay particles over openings in the path of the spoil transport, cohesion of particles and the low probability of clay dissolving in water. This article evaluates a soils clay formations according to clogging potential.
