Title
(EN) IMPROVED METHOD OF RESIN-REINFORCEMENT OF A STONE BLOCK
(FR) PROCÉDÉ AMÉLIORÉ DE RENFORCEMENT PAR RÉSINE D'UN BLOC DE PIERRE
Abstract
(EN)
An improved method of resin-reinforcement of a stone block (1), having cracks (D) and/or shallow or deep defects, comprising the steps of: laying a sheet (2) of flexible waterproof plastic material on a base (3) and placing a block (1) to be resin-reinforced on the sheet (2), b) applying a plurality of spacer members (4) to one or more walls of the block (1), c) anchoring a plurality of panels (5) of rigid sheet material on the walls with the members (4) interposed, to leave a gap (6) between the panels (5) and the side walls of the block (1), d) folding the sheet (2) to form a container (7), e) hermetically sealing the container (7), f) application on the container (7) of at least a first connector (8) and its connection to a vacuum pump (13) by means of first pipes (9) to obtain a vacuum inside the container (7), g) applying at least one first connector (8) to the container (7) and connecting it to a vacuum pump (13) via first pipes (9) to obtain vacuum in the container (7); applying at least one second connector (10) to the container (7), h) introducing a resin (R) into the container (7) via second pipes (11) connected to the container (7), i) maintaining the vacuum in the container (7) to allow the resin (R) to penetrate the gap (6) and the cracks and/or defects (D) until the resin is at least partially cured, and j) disconnecting the pipes (9, 11) and removing the block (1) from the container (7).

La présente invention concerne un procédé amélioré de renforcement par résine d'un bloc de pierre (1), présentant des fissures (D) et/ou des défauts peu profonds ou profonds, comprenant les étapes suivantes : la pose d'une feuille (2) de matière plastique souple imperméable à l'eau sur une base (3) et le placement d'un bloc (1) devant être renforcé par une résine sur la feuille (2), b) l'application d'une pluralité d'éléments d'espacement (4) à une ou plusieurs parois du bloc (1), c) l'ancrage d'une pluralité de panneaux (5) de matériau en feuille rigide sur les parois, les éléments (4) étant interposés, pour laisser un espace (6) entre les panneaux (5) et les parois latérales du bloc (1), d) le pliage de la feuille (2) pour former un récipient (7), e) la fermeture hermétique du récipient (7), f) l'application sur le récipient (7) d'au moins un premier connecteur (8) et sa connexion à une pompe à vide (13) au moyen de premiers tuyaux (9) pour obtenir un vide à l'intérieur du récipient (7), g) l'application d'au moins un premier connecteur (8) au récipient (7) et sa connexion à une pompe à vide (13) par l'intermédiaire des premiers tuyaux (9) pour obtenir un vide dans le récipient (7) ; l'application d'au moins un second connecteur (10) au récipient (7), h) l'introduction d'une résine (R) dans le récipient (7) par l'intermédiaire des seconds tuyaux (11) reliés au récipient (7), i) le maintien du vide dans le récipient (7) pour permettre à la résine (R) de pénétrer dans l'espace (6) et des fissures et/ou des défauts (D) jusqu'à ce que la résine soit au moins partiellement durcie, et j) la déconnexion des tuyaux (9, 11) et le retrait du bloc (1) du récipient (7).
