Abstract

Can be absorbed water lateral spacing constant volume sample box the present invention relates to one kind, be the corrosion and padded coaming pore character evolution research die trial of water saturation stage metal packing material after high-level radwaste geological disposal storehouse is closed.The sample box is made up of sample cavity, base, permeable stone, lucite tube etc..The sample box internal volume is constant and has feed water inlet, is capable of achieving the constancy of its volume during sample water swelling, it is ensured that with the uniformity under true disposal environment;First sample is put into lucite tube during experiment, whole glass tube is put into device again carries out water absorption test, so not only ensure that the convenience sampled after off-test, it is thus also avoided that to the disturbance of sample so as to ensure the authenticity of the follow-up hole test data of sample in sampling process.

Description

One kind can absorb water lateral spacing constant volume sample box

Technical field

During the present invention is for compacting bentonite in lump water suction saturation history, metal erosion/compacting bentonite in lump water suction saturation is simulated A kind of lateral spacing constant volume sample box of front and rear hole Changeement, it is the high-level radwaste geological disposal storehouse of simulation to belong to Artificial barrier water saturation stage metal erosion and padded coaming pore character device for researching, belong at Radwastes treatment Put technical field.

Background technology

In the deep geological disposal of high-level radwaste (HLW), after disposal storehouse is closed, underground water can lentamente to place Put region to infiltrate, buffering backfilling material will start water suction (expansion) and gradually saturation, and underground water will enter one after padded coaming saturation Step is contacted with the packing container surface of dedicated waste tanks and lasted till the entirely full water stage.In the whole water saturation stage, packing container will It is chronically exposed in the pressure of relative constancy (turgor pressure that padded coaming water swelling is produced) and groundwater environment.In expansion Under pressure and underground water coupling, the differentiation of the corrosion condition of packaging material and the pore structure of padded coaming is for entirely The safety evaluation of matter disposal has extremely important effect, it is therefore desirable to carry out related research.In order to carry out and true geology The disposal same or analogous research of evolutionary process, it is necessary to which first developing can simulate the device of true environment.

The content of the invention

The main object of the present invention be just to provide it is a kind of can constant volume and the device that can be absorbed water in the true geological disposal of simulation, The hole properties study device before and after the metal erosion of water saturation stage and bentonite water saturation is provided.

Lateral spacing sample box provided in the invention, there is following characteristics:

This lateral spacing sample box can be supplied water by outside to sample, and inner sample region is constant volume, can be met truly Single disposal hole is constant volume (being also constant volume after water swelling) this real requirement in matter disposal.

Specifically, sample box inside of the invention is equipped with the external diameter lucite consistent with bulk samples chamber internal diameter Pipe, sample is placed in lucite tube, then lucite tube and sample is put into bulk samples chamber together, this mode Be conducive to the handling of sample (sample after the saturation that especially absorbs water), when off-test can directly take out lucite tube, so that can With intactly and also undisturbed take out sample, so can guarantee that sample pore character is unaffected.

The structure of sample box of the invention is simplified, and is easy to operation and high-volume to process.

Brief description of the drawings

Fig. 1 is the structural representation of the lateral spacing constant volume sample box that can absorb water of the invention.

Specific embodiment

The present invention is described in detail with reference to the accompanying drawings and examples.

As shown in figure 1, the sample box includes sample cavity, two bases, two permeable stones, lucite tubes;One permeable Stone is placed in a groove for base, and the sample cavity is placed on one base and a permeable stone, the lucite Pipe is put into the sample cavity;Another permeable stone is placed in the groove of another base, above-mentioned another base and another Permeable stone is upside down in the top of the sample cavity, with said one base and a permeable stone relative to the sample cavity in symmetrical Relation.The base is lined with sealing ring with sample cavity contact position.

Above-mentioned lateral spacing constant volume sample box can be processed in accordance with the following steps:

(1) material selection.It is processed from certain thickness stainless steel and lucite tube;

(2) processing of sample cavity.The stainless steel tube for taking appropriate size carries out sample box sample cavity according to the requirement of regulation Processing, and can place the hole of bolt in the solid section processing of stainless steel tube periphery;

(3) processing of lucite tube.The lucite tube for taking appropriate size is processed according to the size of regulation, in circle Opening groove is processed in cylinder pipe outer wall;

(4) processing of base.The stainless steel substrate of suitable thickness is taken, the disk consistent with sample cavity external diameter is processed as, and A groove that can put permeable stone, and the perforate on the outer wall of disk are processed at the center of disk, hole connects with groove, in circle Disk edge local perforate corresponding with sample cavity bolt hole, for placing bolt.

(5) processing of permeable stone.The suitable permeable stone material of selection is processed as and base groove internal diameter and consistency of thickness Disk.

In the present invention, it is necessary to which the lateral spacing constant volume sample box to processing carries out passed examination, determines sample in sample box Volume be consistent.Inspection method is to use slide measure to machined lateral spacing constant volume sample box sample cavity and organic glass The diameter and height of glass pipe are measured, and the diameter and height difference of test are qualified no more than 0.1mm.

One piece of base is placed on testing stand, while put one piece of supporting permeable stone in groove, while by stainless steel sample Product chamber is positioned on base, and the sample that then will have been prepared is placed in lucite tube, then by the lucite tube of carry sample It is put into stainless steel sample cavity, tightens bolt after then covering another piece of base with permeable stone, last water flowing carries out correlation Experiment.

Obviously, those skilled in the art can carry out various changes and modification without deviating from essence of the invention to the present invention God and scope.So, if these modifications of the invention and modification are belonged to the model of the claims in the present invention and its equivalent technology Within enclosing, then the present invention is also intended to comprising these changes and modification.
