Problems solved by technology
[0003] Due to the particularity of cultural relics, the amount of samples obtained on site is small, irregular and some samples have low strength. Conventional steam permeation test cups cannot fix and seal cultural relic samples well. Therefore, a flexible A moisture-permeable cup with a wall-sealed structure is necessary

The invention relates to a moisture permeable cup with a flexible wall sealing structure for rock soil cultural relics and a moisture permeability testing method. A sample is wrapped in a flexible annular air bag and placed in a moisture permeable cup body, the sample is sealed in a cup opening of the moisture permeable cup and placed in two saturated salt solutions, the annular air bag is adjusted to be inflated and deflated to adapt to samples of different sizes for moisture permeability testing, and the moisture permeability of the samples of different sizes is tested. The annular air bag and the sample are good in sealing effect, sample loading is convenient and fast, moisture permeability tests can be conducted on samples of different specifications by adjusting the inflation amount, and a new device is provided for rock soil cultural relic protection research. The structure is simple in structure and convenient to operate, and has wide application prospects in the fields of cultural relic protection and geotechnical engineering.
Description
technical field [0001] The invention relates to the field of experimental research on the protection of rock and soil cultural relics and the field of reinforcement engineering, relates to the properties of the body of the ruins and the test of the moisture permeability of reinforcement materials, and is of great significance to the research on the protection and reinforcement of rock and soil cultural relics. The invention is also applicable to related fields such as geotechnical engineering. Background technique [0002] my country has a large number of rock and soil immovable cultural relics, and its materials include glutenite, sandstone and soil with different composition properties. Water vapor is one of the main factors for the developmental disease of the site body. There are many sources of water vapor. It is very difficult to block water vapor, and it is easy to develop secondary diseases. Therefore, the protection and reinforcement materials of the site body shoul...
