Abstract

Procedimento di avanzamento di gallerie come pure macchina di avanzamento a scudo per l'attuazione di questo procedimento. In un procedimento di avanzamento di gallerie con impiego di una macchina di avanzamento a scudo (1), in cui utensili abbattitori (3) sono appostati al fronte di avanzamento del luogo (26) e vengono mossi oltre il fronte di avanzamento del luogo (24), gli utensili abbattitori (3) dopo un primo movimento di avanzamento vengono mossi in direzione verso il fronte di avanzamento del luogo (24) attraverso un settore del fronte di avanzamento del luogo, mentre contemporaneamente i settori rimanenti del fronte di avanzamento del luogo (24) vengono sostenuti attraverso mezzi di sostegno meccanici (11, 12). Nel caso di una macchina di avanzamento a scudo con utensili abbattitori (3) supportati entro uno scudo di avanzamento (1), in cui gli utensili abbattitori (3) sono girevolmente disposti attorno ad un asse centrale (20) ed è previsto un azionamento di avanzamento (21) efficace in direzione dell'asse centrale (20), gli utensili abbattitori sono formati da almeno un cilindro intagliatore o rispettivamente da almeno una testa intagliatrice (3) e sono supportati su un braccio a sbalzo (2) girevole attorno all'asse centrale (20), l'asse di rotazione (26) del cilindro intagliatore o rispettivamente della testa intagliatrice (3) essendo disposto/a sostanzialmente parallelo/a all'asse centrale (20), e il cilindro intagliatore o rispettivamente la testa intagliatrice (3) essendo spostabile in direzione radiale dello scudo di avanzamento (Figura 1).Tunnel advancement method as well as shield advancement machine for the implementation of this method. In a tunnel advance procedure using a shield advance machine (1), in which blast chopping tools (3) are placed on the site advance front (26) and are moved beyond the site advance front (24 ), the blast chopping tools (3) after a first advance movement are moved in a direction towards the site advance front (24) through a sector of the site advance front, while at the same time the remaining sectors of the site advance front ( 24) are supported through mechanical support means (11, 12). In the case of a shield feed machine with blast chopping tools (3) supported within a feed shield (1), in which the blast chopping tools (3) are rotatably arranged around a central axis (20) and a advancement (21) effective in the direction of the central axis (20), the cutting tools are formed by at least one cutting cylinder or respectively by at least one cutting head (3) and are supported on a cantilever arm (2) which can rotate around the central axis (20), the rotation axis (26) of the cutting cylinder or respectively of the cutting head (3) being arranged substantially parallel to the central axis (20), and the cutting cylinder or respectively the cutting head (3) being movable in the radial direction of the feed shield (Figure 1).
