Abstract

The invention discloses a device and a method for testing the healing effect of a combined joint of buffer material building blocks. The testing device comprises a transparent plate structure, a connecting pipeline, a water inlet system, a water vapor outflow system, a sample, a camera and a data acquisition system. By collecting the images and video data of the joint healing process between the buffer material building blocks and a surrounding rock and the joint healing process between the combined building blocks in real time, the whole joint healing process is obtained, the joint healing effect rule of the buffer material combination of a disposal repository is disclosed, and a basis can be provided for engineering design of a high-level radioactive waste deep geological disposal repository.

Description

technical field [0001] The invention relates to the technical field of cushioning materials for a high-level radioactive waste repository, in particular to a device and method for testing the healing effect of a combined joint of a cushioning material block. Background technique [0002] In the geological repository of high-level radioactive waste, the buffer material, as an important part of the multiple barrier system, is filled between the surrounding rock and the waste tank to prevent the infiltration of groundwater and the migration of radioactive waste leaked from the waste tank to the surrounding environment. [0003] Engineering barrier construction is divided into compacted block masonry method and in-situ compaction method. The compacted block masonry method is used for construction, and joints will be generated between the buffer material block and the surrounding rock and between the combined blocks. The existence of seams will reduce the ability to dissipate the...
