Restoration Technology of Damaged Stone Carvings in Ancient Grottoes of World Cultural Heritage

Abstract

The invention discloses a restoration process for damaged stone carvings in ancient grottoes of world cultural heritage. Firstly, the damaged stone carvings are repaired through a 3D digital quick repair method, information is directly collected at the grotto site, and the original model and the repaired model are made respectively by using 3dsmax modeling tools, and then the two According to the stone carving model, the original damaged stone carving is kneaded and repaired with reinforced pottery clay to manufacture the repaired shape of the stone carving, and the repaired shape of the stone carving is irradiated with LED cold light source ultraviolet curing equipment and then cured quickly. The cured stone carving repair shape is installed on the movable height-changing round pad support repair bracket, and is moved to the original damaged stone carving at the grotto site, supported, glued, and polished. After it is completely dry, the movable height-changing round pad is removed The pad supports the repair bracket, that is, the repair is successful. The repair time of the present invention is short, the cost is low, the precision is high, and the effect is good, and the on-site fixation does not require a crane, accurate displacement, precise contact between the repair model and the original cave, and accurate adhesion.

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
