Abstract

The utility model belongs to the technical field of radioactive waste treatment, in particular to a cement solidification mold trial for treating radioactive waste. The cement solidification mold trial comprises a tubular mold trial body made of organic glass, a base plate is arranged under the mold trail body and fixedly bonded with the same, and a longitudinal open groove is arranged on the mold trail body. The cement solidification mold trial can complete demoulding operation fast, reduce radioactive operation time and decrease radiation dose of operators. Because the mold trial body is made by organic glass, apparent mass of solidification can be measured visually during pouring and stamping, and then the mold trial can not be damaged and the solidification mold can not deform during a cement stamping process.

Description

The solidified cement body die trial
Technical field
The utility model belongs to the radioactive waste processing technology field, is specially a kind of solidified cement body die trial that is used to handle radioactive waste.
Background technology
At present, domestic low, middle horizontal radiation refuse is implemented cement solidification/fixing.The refuse body that cement solidification produces need carry out Performance Detection." low, middle horizontal radiation solidification of waste body performance requirement-solidified cement body " (GB 14569.1) have stipulated the curing sample of Performance Detection use φ 50 * 50mm.
According to the requirement of GB 14569.1, the preparation of solidified cement body sample need be used the right cylinder die trial.Yet, at present to the ununified regulation of right cylinder die trial.The die trial that is used in the practical operation has glass beaker, vinyon cup (add a cover or do not add a cover) etc.These die trials all have its tangible weak point in operating process.
(1) in the solidified cement body preparation, grout needs to time in fact after pouring die trial into, so that remove bubble.If use glass beaker as solidifying die trial, be not easy to pausing in fact of grout.Like this, the firming body sample of preparation often has a lot of pores, so make firming body mechanical property and (or) water repelling property is undesirable.
(2) grout was poured the die trial maintenance into after 28 days, need slough die trial, carried out Performance Detection after solidifying the sample polishing.Use the vinyon cup as solidifying die trial, be not easy to the demoulding.Find in the practical operation that use the vinyon cup to prepare firming body and also have the real phenomenon of not paused fully, the firming body performance is also undesirable.
Summary of the invention
The purpose of this utility model is at having glass beaker or the vinyon cup defective as the solidified cement body die trial now, a kind of novel solidified cement body die trial is provided, thereby the further preparation of standard solidified cement body, the operability of strengthening solidifying specimen preparation.
The technical solution of the utility model is as follows: a kind of solidified cement body die trial, comprise the tubulose die trial main body of an organic glass material, and die trial main body below is provided with base plate, and die trial main body and base plate are adhesively fixed, and have an opening groove longitudinally on the die trial main body.
Further, aforesaid solidified cement body die trial, wherein, the wall thickness of described die trial main body is 4mm~6mm, internal diameter is 50mm ± 1mm.
Further, aforesaid solidified cement body die trial, wherein, the width of described opening groove is 2mm~3mm, the degree of depth of opening groove is 2mm~3mm.
The beneficial effects of the utility model are as follows:
(1) die trial main body is a right cylinder, for the ease of solidifying the demoulding after the sample maintenance expires, die trial has been designed an independently base plate; And be processed with opening groove on the right cylinder, so that do not destroy under the prerequisite of solidifying sample, comparatively fast finish stripping operation, particularly in the preparation process of true refuse cement solidification sample in assurance, can reduce the time of hot operation, reduce operating personnel's radioactive dose.
(2) die trial main body adopts the organic glass material, can in a grouting and a real process, estimate the apparent mass of firming body, organic glass has certain toughness and hardness, can in grout pauses real process, guarantee not destroy die trial and not make the firming body distortion, organic glass has fragility preferably, can after the maintenance expiration, finish stripping operation well and not destroy solidified cement body.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
As shown in Figure 1, solidified cement body die trial provided by the utility model comprises the tubulose die trial main body 1 of an organic glass material, die trial main body 1 below is provided with base plate 3, and die trial main body 1 is adhesively fixed with base plate 3, has an opening groove 2 longitudinally on die trial main body 1.The wall thickness of die trial main body is 4mm~6mm, and internal diameter is 50mm ± 1mm, and the width of opening groove is 2mm~3mm, and the degree of depth of opening groove is 2mm~3mm.
The utility model selects the plexi-glass tubular of certain wall thickness and internal diameter and the poly (methyl methacrylate) plate of suitable thickness to process, plexi-glass tubular height according to the rules is processed into the die trial main body, the opening groove of on cylindrical pipe, processing, the plexi-glass tubular that is processed into is adhered on the poly (methyl methacrylate) plate that processes with suitable organic reagent, the center of plexi-glass tubular is basic consistent with the center of poly (methyl methacrylate) plate.
Before the solidified cement body die trial is used, must carry out passed examination to the die trial of processing, determine the sealing of die trial bottom.Inspection method is a topped up with water in the die trial of being processed into, and placement is spent the night, with water-tight be qualified.
During use, grout is poured in the die trial of passed examination, treated the maintenance expiration back demoulding.Slough base plate during the demoulding earlier, along opening groove die trial is opened again, take out and solidify test block.To carry out recycling to intact base plate and die trial main body.
