<p>Continuous method of realisation of underground works of whatsoever nature, with consolidation (6) before excavation, where said consolidation is carried out by means of guided perforations (3), obtained with swinging head perforation equipment (4,5), arranged peripherally in the nucleus or in the position indicated by the designer of the tunnel being built (1), or in underground work, and where said consolidation (6) within the guided perforation takes place by means of filling of each perforation (3) with reinforcements or inserts later mixed with aggregating substances injected at high or low pressure, or by means of a jet-grouting system with a pressure jet of cement mixtures, gel, resins etc., so that the consolidation before excavation takes place for long stretches, or for the entire length of the tunnel or the surface of the underground works, with attainment of a resistant work, according to precise static conditions, in that such guided perforations are traced exactly according to the design even following curved routes. <IMAGE></p> |
