Abstract

Soutènement à arceaux coulissants, composés de segments en gouttière emboîtés les uns dans les autres, qui sont préassemblés et attachés provisoirement pour être ensuite déployés, sur le lieu d'installation, pour former un arceau de soutènement complet. Pour empêcher les segments (2, 4; 4. 6; 3, 5, 5, 7) maintenus emboîtés par des attaches 8, alors desserrées, de s'échapper les uns des autres hors de leur coulissement pour le déploiement de l'arceau, l'invention prévoit sur les surfaces en regard des segments coulissants, vers les extrémités de ces segments, des butées coopérant mutuellement pour s'opposer à cet échappement. Application : soutènement de galeries de mines.Support with sliding arches, composed of gutter segments nested in one another, which are preassembled and temporarily attached to then be deployed, at the place of installation, to form a complete retaining arch. To prevent the segments (2, 4; 4.6; 3, 5, 5, 7) held together by clips 8, then loosened, from escaping each other out of their sliding for the deployment of the hoop , the invention provides on the surfaces facing the sliding segments, towards the ends of these segments, stops cooperating with each other to oppose this escape. Application: support of mine galleries.
