Problems solved by technology

However, there are still few experimental studies related to this at present, so it is urgent to carry out research on the joint healing effect of bentonite blocks.
The laboratory tests on the healing effect of bentonite block joints generally use stainless steel pressure chambers. After the sealed sample is filled with water and tested for a long time, the device is disassembled to check the joint healing status. It is impossible to observe the whole process of bentonite block joint healing in real time. Grasp the Law of Healing Effect of Bentonite Block Joints in Time

Abstract

The invention discloses a bentonite block single joint healing effect testing device and method. The device comprises a transparent plate structure, a connecting pipeline, a water inlet system, a sample, a metal water permeable plate, a camera and a data acquisition system. Compared with the prior art, the device has the advantages that image and video data of the building block joint healing process can be collected in real time, the whole building block joint healing process is obtained, the bentonite building block joint healing effect rule is disclosed, and a basis is 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 single joint of a bentonite block. Background technique [0002] Bentonite is not only widely used in the fields of petroleum, metallurgy and building materials due to its low permeability, high expansion and high adsorption properties, but also is selected as the base material for buffer backfill materials for geological disposal of high-level radioactive waste. The compacted blocks pressed into different shapes are stacked around the waste tank, which acts as a mechanical barrier and a chemical buffer, and can effectively block the migration of radionuclides to the environment. [0003] Although there are joints between the stacked blocks, the expansion of the compacted bentonite blocks in contact with water can be used to achieve effective healing of the joints of...
