Semi-closed type full-coverage separation method used for weathering protection of inscriptions on precipices and slopes

Abstract

The invention discloses a semi-closed type full-coverage separation method used for weathering protection of inscriptions on precipices and slopes. The semi-closed type full-coverage separation method is composed of a grid type framework, a double-support-plate bilaterally adjustable support base, a unilaterally adjustable support base, a single-support-plate bilaterally adjustable support base, transparent cover plates and a watering and cooling device. The lower ends of the double-support-plate bilaterally adjustable support base, the unilaterally adjustable support base and the single-support-plate bilaterally adjustable support base are fixed on the grid type framework; through the height adjustment of the support bases, the inclination angle of each transparent cover plate and a gap between adjacent cover plates can be changed. The transparent cover plates are assembled and paved along the slope surface of the inscriptions on precipices from downside to upside, and the adjacent cover plates which incline along the slope surface are paved in an imbricate manner. In order to avoid too high temperature of stones caused by sunlight exposure, the watering and cooling device can be turned on to enable the water to flow through the surfaces of the transparent cover plates from upside to downside and cool as well as clean the cover plates. The semi-closed type full-coverage separation method used for weathering protection of inscriptions on precipices and slopes achieves the advantages of obvious long-term effect, strong reversibility, installation convenience, easy maintenance, relatively low cost, no obstruction to tourism and view, and the like.

Description

technical field [0001] The invention relates to the technical field of protection of stone cultural relics, in particular to a semi-enclosed full-coverage isolation method for weathering protection of rock carvings on slopes and cliffs. Background technique [0002] The so-called stone cultural relics refer to those relics with historical, artistic and scientific value that are processed and manufactured with natural stone as raw materials in the process of human historical development. Stone cultural relics include not only stone inscriptions, stone works of art, and stone utensils of the Stone Age, but also cliff carvings, cave temples, and architectural stone components with historical or artistic value. For those stone cultural relics that are closely related to the site environment and cannot be transported, they can be called immovable stone cultural relics, such as cliff carvings and cave temples. Cliff carvings refer to characters, statues or petroglyphs carved on c...

AI Technical Summary

Problems solved by technology

[0028] The purpose of this invention is to solve the problems of insufficient anti-aging ability, poor air permeability, poor reversibility, and insufficient attention to changes in rock temperature and humidity in the chemical anti-weathering technology of cliff stone carvings. A physical protection method that is convenient, easy to maintain, and convenient for sightseeing, so as to improve the long-term effect of weathering of cliff carvings and the development of subsequent weathering work
