HYDRAULIC DEBRIS CLEARANCE IN MECHANIZED TUNNELLING

On an international level, considerable experience is available in the field of vertical and horizontal hydraulic transport of solid matter. This experience, however, mostly relates to stationary complex and costly systems for coal transport. General aim of the project was establishment of reliable data relative to process and mechanical engineering for a hydraulic debris clearance system for mechanized tunnelling. The work was particularly aimed at: investigations on stresses to which hydraulically transported matter is exposed; wear investigations on pumps and pipings; analyses of transport phenomena by measuring; observation of the separation plant. These investigations enabled guidelines to be established which are to be regarded as a useful base for project work on a clearance system for 6 m dia. full-face tunnelling machines.
