Mechanized tunneling through clayey formations is threatened to encounter the clogging problem. Adhesion stress as the tendency between clay and a metal surface leads to clogging between TBM and excavated materials. Some empirical clogging...

Clogging occurs during mechanical tunneling with a Tunnel Boring Machine (TBM) because of adhesion of clayey soils to the cutter head and conveyor system. The present study examined the effects of water and sand contents on clogging...

Adhesion in geotechnical engineering is the interaction between cohesive soil and a solid surface which can cause clogging in mechanized tunnelling through clayey formations. Normal piston pull out and modified direct shear tests were performed...

The tendency of clay particles to stick other surfaces means it is adhesive and can cause clogging of tunnel boring machines. Clogging arising from adhesion hinders or halts tunneling operations. The nature of adhesion in the interaction of soil...

Bottom rack intake is one of the most popular structures for diverting water in steep rivers. The

problems of corrosion, deformity and clogging of the bottom racks in long term, inspires a new

system of bottom intake in which a filled...
