Repair process of damaged stone carving of world cultural heritage ancient grotto

Abstract

The invention discloses a repair process of a damaged stone carving of a world cultural heritage ancient grotto. The method comprises the following steps that the damaged stone carving is repaired bya 3D digital rapid repair method, information is directly collected on the grotto site, an original model and a repair model are manufactured by using a 3 dsmax modeling tool, is the original model and the repair model are synthesized to prepare a stone carving model, and kneading and plastic repairing are carried out on the original damaged stone carving by using reinforced pottery clay accordingto the stone carving model, a stone carving repairing shape is manufactured, an LED cold light source ultraviolet curing device is used for irradiating the stone carving repairing shape and then rapidly curing, the solidified stone carving repair modeling is installed on a movable high-height circular pad support repairing support, and is moved to be synchronously aligned with the original damaged stone carving at the grotto site, supporting, bonding and polishing, and waiting for drying, and the movable high-height circular cushion is removed to support a repairing bracket, that is, the repairing is successful. According to the repair process, the repairing time is short, the cost is low, the precision is high, the effect is good, a crane does not need to be fixed on the site, accurate displacement is achieved, the repair model is accurate in contact with the original carving, and adhesion is accurate.

Description

technical field [0001] The invention belongs to the technical field of repairing damaged stone carvings, and in particular relates to a repairing process for damaged stone carvings in ancient grottoes of the world cultural heritage. Background technique [0002] The existing restoration methods for damaged stone carvings in traditional grottoes mainly include "handmade model restoration method" and "digital restoration method". The "digital restoration method" has a long preparation time and a long production cycle; there are many technicians; the collection site requires harsh conditions and high technical requirements for personnel; the equipment is extremely expensive and difficult to operate, and the existing traditional grottoes. Repair materials need to be baked in a large oven for a long time, which is time-consuming and laborious; [0003] At the same time, the existing on-site adhesion technology for damaged stone carvings and repaired models in traditional grottoe...

[0002] The existing restoration methods for damaged stone carvings in traditional grottoes mainly include "handmade model restoration method" and "digital restoration method". The "digital restoration method" has a long preparation time and a long production cycle; there are many technicians; the collection site requires harsh conditions and high technical requirements for personnel; the equipment is extremely expensive and difficult to operate, and the existing traditional grottoes. Repair materials need to be baked in a large oven for a long time, which is time-consuming and laborious;

[0003] At the same time, the existing on-site adhesion technology for damaged stone carvings and repaired models in traditional grottoes mainly uses the method of building steel frame support and crane movement, which leads to insufficient support at the bottom, uneven support force, easy misalignment, and very long preparation time. Long, costly, and large land area
