Multi-field coupling based rock cave surrounding rock weathering and wall painting salt damage simulation test apparatus

Abstract

The invention relates to a multi-field coupling based rock cave surrounding rock weathering and wall painting salt damage simulation test apparatus. The apparatus is divided into a summer bin, a wind and rain bin and a winter bin. The above three bins are connected through heat insulation storehouse doors to form one body. Movable sunlight exits in the summer bin, and can be used for stimulating medium-high temperature environment and the sunlight effect at different radiation intensities and angles; the top of the wind and rain bin is provided with a rainfall device in order to stimulate rainfall, and the wind and rain combination erosion effect can be stimulated through a blowing device; low temperature environment, snow fall and sunlight snow melting stimulation can be carried out in the winter bin; and the ground is provided with steel rails in order to provide conveniences for the movement of a test piece among the bins. The apparatus can realize the independent test of different test pieces in the three bins, and can realize the continuous circulation test of a same test piece in the three bins. The apparatus greatly improves the test flexibility, the apparatus use efficiency and the equipment reliability, and provides a test platform for researching the deterioration of multiple factor coupling to earthen sites comprising rock caves, wall paintings and the like.

Description

technical field [0001] The invention relates to a multi-field coupling simulation test device for the weathering of surrounding rocks in grottoes and the salt damage mechanism of murals.

AI Technical Summary

Problems solved by technology

Environmental simulation technology under the condition of multi-field coupling is a new technology that integrates the artificial reproduction technology of various natural environments and engineering tests in simulated environments. It has formed an independent technical theory in solving the theory and practice of environmental simulation and environmental tests. The system has outstanding advantages such as time controllability, conditional repeatability and data accuracy. However, this technology is still a blank in the research of cultural relics protection.

[0003] Due to the particularity of the protection of cultural relics and the limitation of the application of existing experimental methods in the protection of cultural relics, the current research on the weathering of grotto surrounding rocks and the salt damage mechanism of murals mostly adopts the method of single-field or multi-field physical superposition, which leads to the depth of revealing the disease mechanism. Not enough; at the same time, a large number of samples were taken for indoor research and many instruments and methods that can be used for geotechnical in-situ testing cannot be used in grotto protection. Only some non-destructive tests and simulation tests can be used to study the weathering of grotto surrounding rocks and the salt damage of murals occurrence, development process
