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

Embodiment Construction

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] The purpose of the present invention is to provide a single seam healing effect testing device and method of bentonite blocks, which can collect images and video data of the healing process of the block joints in real time, obtain the whole process of the joint healing of the blocks, and reveal the joints of the bentonite blocks. The law of healing effect provides a basis for engineering design of deep geological repository for...

Abstract

The invention discloses a single seam healing effect testing device and method of bentonite blocks, wherein the device includes a transparent plate structure, a connecting pipeline, a water inlet system, a sample, a metal permeable plate, a camera and a data acquisition system. Compared with the prior art, the present invention can collect images and video data of the block joint healing process in real time, obtain the entire block joint healing process, reveal the law of the bentonite block joint healing effect, and provide deep geological disposal of high-level radioactive waste. Library engineering design provides the basis.

Description

technical field [0001] The invention relates to the technical field of buffer materials for high-level radioactive waste disposal warehouses, in particular to a device and method for testing the healing effect of a single seam 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, high adsorption and other characteristics, but also selected as the base material for buffer backfill materials for geological disposal of high-level radioactive waste. It is pressed into different forms of compacted blocks and stacked around the waste tank, which acts as a mechanical barrier and chemical buffer, which 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 o...
