Description

本発明は、アルカリシリカ反応の判定を簡易に行なう為の判定装置に関する。   The present invention relates to a determination apparatus for easily determining an alkali silica reaction.

従来、酢酸ウラニル溶液をコンクリートに塗布し、暗室で紫外線を照射することにより、発光するアルカリシリカゲルの存在を確認する手法が広く知られている。
アルカリシリカゲルとは、反応性鉱物(反応性シリカ鉱物や炭酸塩岩等)を含む骨材がコンクリート中のアルカリ溶液と反応して生成するものである。これが、吸水・膨張することにより、コンクリートに異常膨張やひび割れを発生させ、コンクリート構造物の劣化現象を誘発する原因となるものである。
Conventionally, a technique for confirming the presence of alkali silica gel that emits light by applying a uranyl acetate solution to concrete and irradiating ultraviolet rays in a dark room is widely known.
Alkali silica gel is produced when an aggregate containing reactive minerals (reactive silica minerals, carbonate rocks, etc.) reacts with an alkaline solution in concrete. This causes abnormal expansion and cracks in the concrete due to water absorption and expansion, and causes deterioration of the concrete structure.

WO2006/049192号公報WO2006 / 049192

酢酸ウラニル溶液等を使用したアルカリシリカ反応判定は、比較的簡易にアルカリシリカゲルの存否を判定し得るものであることから、現場において試料を採取しつつ判定し、且つ通常の態様及び紫外線照射による発光状況を撮影して、機動的にデータ収集を行なうことが望まれる。   Alkaline silica reaction determination using a uranyl acetate solution or the like can determine the presence or absence of alkali silica gel relatively easily. It is desirable to capture the situation and collect data flexibly.

しかしながら、撮影には暗室を要するのみならず、撮影を要する面を撮像装置に向け、多数のサンプルについて同じ撮影条件で静止させておく支持手段が必要である。
また、酢酸ウラニル溶液等の試薬は、放射性物質であり、試薬や廃棄物の扱い管理には細心の注意が必要であるところ、従来の装置では、試料を交換する毎に、判定に用いた道具の洗浄といった煩雑な作業が不可欠であり、そういった作業を行う施設を、試料を採取できる現場に求めることは極めて困難であった。
However, not only a darkroom is required for photographing, but also a support means for keeping the surface that requires photographing toward the image pickup apparatus and keeping many samples stationary under the same photographing conditions.
In addition, reagents such as uranyl acetate solution are radioactive materials, and careful handling is necessary for the management of reagents and wastes. With conventional devices, the tool used for the determination every time the sample is replaced. Therefore, it is extremely difficult to find a facility for performing such work at a site where samples can be collected.

尚、他分野であるが、一定の条件下で撮影できる道具として、上記特許文献1に記載の皮膚トリートメント装置が挙げられる。しかしながら、この文献に開示された技術では、試料としての人肌に圧着する形態を採っており、本願発明における上記課題の解決に貢献し得る記載は無い。   In addition, although it is another field | area, the skin treatment apparatus of the said patent document 1 is mentioned as a tool which can be image | photographed on fixed conditions. However, the technique disclosed in this document adopts a form in which it is pressed against human skin as a sample, and there is no description that can contribute to the solution of the above problem in the present invention.

本発明は上記実情に鑑みてなされたものであって、暗所と明所を実現でき、試料を同じ撮影条件下におくことができ、且つ容器内の洗浄が容易な携帯性の高いアルカリシリカ反応判定装置の提供を目的とする。   The present invention has been made in view of the above circumstances, and can realize a dark place and a bright place, a sample can be placed under the same photographing conditions, and a highly portable alkali silica that can be easily cleaned in a container. An object is to provide a reaction determination device.

上記課題を解決するための手段は、蓋及び容器本体からなる遮光性容器を備え、蓋の裏面中央部に、封鎖時において容器本体に向けられる撮像手段を備え、蓋の裏面縁部に、封鎖時において容器本体を照らす紫外線ランプ及び白色ランプを備え、容器本体の内部底面に、吸水性を有する低反発マットを脱着可能に敷設し、判定容器の外部に、撮像手段を機能させ、又は紫外線ランプ若しくは白色ランプを選択的に点灯させる操作手段を備えるアルカリシリカ反応判定装置である。   Means for solving the above problems includes a light-shielding container composed of a lid and a container body, and includes imaging means directed to the container body at the time of sealing at the center of the back surface of the lid, and sealing at the back edge of the lid. It is equipped with an ultraviolet lamp and a white lamp that illuminate the container body at the time, and a low-resilience mat with water absorption is detachably laid on the inner bottom surface of the container body, and the imaging means functions outside the determination container, or the ultraviolet lamp Or it is an alkali silica reaction determination apparatus provided with the operation means which selectively turns on a white lamp.

撮像手段は、CCDカメラ等である。
紫外線ランプや白色ランプは、試料の蓋に面する面へ全周から影を造ることなく均一に照らせる態様で配置すればよく、光源が単一であるか複数であるかを問わない。
低反発マットとは、人力によって凹むが、反発復帰作用が極めて緩やかに生じる性状を持つシート状の発泡成形物等である。
The imaging means is a CCD camera or the like.
The ultraviolet lamp and the white lamp may be arranged in such a manner that they can be illuminated uniformly on the surface facing the lid of the sample without creating a shadow from the entire circumference, regardless of whether the light source is single or plural.
The low-rebound mat is a sheet-like foamed molded article or the like that has a property of being relieved by human power but generating a rebound-returning action very gently.

容器本体の内部底面に、吸水性を有する低反発マットを脱着可能に敷設する構成に換えて、容器本体の内部底面に、通水性を有する低反発マットを脱着可能に敷設し、容器本体の底壁内面に、弾性低反発マットを通過した試薬を溜める液溜りを備えるアルカリシリカ反応判定装置とすることもできる。   Instead of a configuration in which a water-repellent low-resilience mat is detachably laid on the inner bottom surface of the container body, a water-repellent low-resilience mat is detachably laid on the inner bottom surface of the container body. It can also be set as the alkali silica reaction determination apparatus provided with the liquid reservoir which accumulates the reagent which passed the elastic low-resilience mat on the wall inner surface.

遮光性容器は、簡易な暗室となり、蓋の裏面中央部に、封鎖時において容器本体に向けられる撮像手段を備えることによって、容器の内空部における一定の位置から試料を撮影することができる。
蓋の裏面縁部に、封鎖時において容器本体を照らす紫外線ランプ及び白色ランプを備えることによって、暗所において照射する光を選択し、明所における試料の外観像と暗所において発光した試料の外観像とを、同じ撮影条件において、対比できる態様で撮影することができる。

容器本体の内部底面に、吸水性を有する低反発マットを脱着可能に敷設することによって、種々の形状を有する試料を所望の向きに安定した状態で定着することができると共に、試料に散布した試薬の余分を低反発マットに吸収し、データを取り終えた後に試料とともに取り外して廃棄することができる。
また、低反発マットを交換して別の試料を固定してデータ収集を図ることができる。
判定容器の外部に操作手段を備えることによって、遮光性容器を開けることなく、撮像手段を機能させ、又は紫外線ランプ若しくは白色ランプを選択的に点灯させることができる。
By detachably installing a low-resilience mat with water absorption on the inner bottom surface of the container main body, it is possible to fix samples having various shapes in a stable state in a desired direction and to spread the reagents on the samples. After the data is collected, it can be removed and discarded together with the sample.
In addition, data collection can be achieved by replacing the low resilience mat and fixing another sample.
By providing the operation means outside the determination container, the imaging means can function or the ultraviolet lamp or the white lamp can be selectively turned on without opening the light-shielding container.

容器本体の内部底面に、通水性を有する低反発マットを脱着可能に敷設し、容器本体の底壁内面に、弾性低反発マットを通過した試薬を溜める液溜りを備える構造を採用することによって、アルカリシリカ反応試薬を回収することができる。   By adopting a structure in which a water-repellent low-resilience mat is detachably laid on the inner bottom surface of the container main body, and a liquid reservoir is provided on the bottom wall inner surface of the container main body to store the reagent that has passed through the elastic low-resilience mat. The alkali silica reaction reagent can be recovered.

The inner surface or the side surface of the bottom wall is provided with a rotation stopper 1i such as a protruding piece that bites into the side surface of the low-repulsion mat 5 so that the orientation of the sample S relative to the container body 1b does not change when the laid low-repulsion mat 5 rotates. .

低反発マット5には、吸水性発泡ウレタンフォーム(例えば、特表2002−519042号公報、又は実用新案登録第3128247号公報参照)等の発泡合成樹脂、試料Sを装着する際の人為的加圧によって部分的に破壊することが可能なハニカム構造など多数の気室を有する紙製のシート、又は、それらと同等の構造を有する樹皮や木片等を用いる。   The low-rebound mat 5 is artificially pressurized when a foamed synthetic resin such as a water absorbent foamed urethane foam (see, for example, Japanese Patent Publication No. 2002-519042 or Utility Model Registration No. 3128247) or the sample S is mounted. A paper sheet having a large number of air chambers such as a honeycomb structure that can be partially broken by the above, or a bark or a piece of wood having a structure equivalent to them is used.

The operation unit 6 supplies power to the power source unit 13 that supplies power to the imaging device unit, the focus adjustment function of the imaging unit 2 and the imaging control signal generation unit 9 that controls the start / stop of imaging, the ultraviolet lamp 3, and the white lamp 4. The illumination control signal generation unit 11 for supply, the ultraviolet lamp 3 and the white lamp 4 are selectively turned on or off, and a switch unit 10 is provided for performing a focus adjustment function and a start / stop operation for photographing (FIG. 4). reference). A control signal generated by the operation means 6 is supplied to the imaging means 2 provided inside the lid 1a, the ultraviolet lamp 3 and the white lamp 4 via the cable 12. The cable lead portion of the lid 1a is sealed with a light shielding material to prevent light from leaking.
If image data is taken out from the image pickup means 2 via the cable 12, a recording medium driver can be provided integrally with the operation means 6.

以上の如く構成されたアルカリシリカ反応判定装置を用いれば、データの採取を行なうにあたり、先ず、試料Sを低反発マット5押し付け、低反発マット5の表面に嵌め込む(図1(B)及び図2(A)参照)。その際、試料Sの表面のうち、撮影しようとする面(以下、撮影面と記す。)を撮像手段2のレンズ2bに向け、撮影面をレンズ2bに対してできるだけ平行にする。固定の態様が決まれば、固定された試料Sの撮影面に試薬(酢酸ウラニル溶液)を適量吹付けた後、軽く水(以下、洗浄水と記す。)で洗い流し、遮光性容器1の蓋1aを閉じる。   When using the alkali silica reaction determination apparatus configured as described above, when collecting data, first, the sample S is pressed against the low-repulsion mat 5 and fitted into the surface of the low-repulsion mat 5 (FIG. 1B and FIG. 2 (A)). At that time, a surface to be photographed (hereinafter referred to as a photographing surface) of the surface of the sample S is directed to the lens 2b of the imaging means 2, and the photographing surface is made as parallel as possible to the lens 2b. When the fixing mode is determined, an appropriate amount of a reagent (uranyl acetate solution) is sprayed on the imaging surface of the fixed sample S, and then lightly rinsed with water (hereinafter referred to as “washing water”), and the lid 1a of the light-shielding container 1 is placed. Close.

こうして、試料Sは、回転止め1iにより回転が禁止された低反発マットに支持され、逆さにし、又は急激な衝撃を与えない限り、嵌め込まれた位置で、嵌め込まれたままの姿勢を維持する。この作用が方位固定構造8と相俟って、レンズと試料との位置関係、距離関係、及び位相関係が決まり、操作手段で露光やシャッター速度を一旦決めれば、何度蓋1aを開け閉めしようとも、同じ位置条件で試料Sを撮影することが可能となる。   In this way, the sample S is supported by the low-repulsion mat whose rotation is prohibited by the rotation stopper 1i, and maintains the inserted posture at the inserted position unless it is turned upside down or given a sudden impact. This action combined with the azimuth fixing structure 8 determines the positional relationship, distance relationship, and phase relationship between the lens and the sample, and once the exposure and shutter speed are determined by the operating means, the lid 1a should be opened and closed many times. In both cases, it is possible to photograph the sample S under the same position conditions.

撮影環境は、紫外線ランプ3が照射されている環境での撮像(アルカリシリカゲルの発光像)と、白色ランプ4が照射されている環境の撮像(自然環境下での外観像)を操作手段6で選択することができる。上記の如く、位置条件が決まっていることから、発光像と外観像の形態と状態とが整合し、暗所撮影による発光像において試料Sの輪郭が不鮮明であっても、比較的容易に精密な比較対照を行なうことが可能となる。   The operation environment 6 is used to capture an image in an environment irradiated with the ultraviolet lamp 3 (light emission image of alkali silica gel) and an image of an environment irradiated with the white lamp 4 (appearance image in a natural environment). You can choose. As described above, since the position conditions are determined, the form and state of the luminescent image and the appearance image are matched, and even if the outline of the sample S is unclear in the luminescent image obtained by dark place photography, it is relatively easy It is possible to perform a comparative comparison.

データを取り終えた後、低反発マット5、低反発マット5に吸収された試薬や洗浄水は、試料Sとともに取り外して廃棄する。また、液溜り1hに溜まった試薬や洗浄水は、所定の容器に回収する。   After collecting the data, the low resilience mat 5 and the reagent and washing water absorbed by the low resilience mat 5 are removed together with the sample S and discarded. In addition, the reagent and washing water collected in the liquid reservoir 1h are collected in a predetermined container.

アルカリシリカゲルの吸着力を利用すれば、試薬には、酢酸ウラニル溶液以外の弱アルカリ性蛍光物質(例えば、硝酸ウラニン標準液、蛍石、ウラニン溶液(フルオレセインナトリウム)等が挙げられる。)を用いることができる可能性がある。   If the adsorptive power of alkali silica gel is used, a weak alkaline fluorescent substance other than uranyl acetate solution (for example, uranine nitrate standard solution, fluorite, uranin solution (fluorescein sodium), etc.) may be used as a reagent. There is a possibility.

酢酸ウラニル溶液は、高濃度のウランを含む放射性溶液であり、一般的には溶液の扱いや廃棄物の扱いに公的な規制が存在することから、この様な規制を回避できる安全で扱い易い試薬が求められていた。以下、硝酸ウラニン標準液についての試験結果の一部を示す。   Uranyl acetate solution is a radioactive solution containing a high concentration of uranium, and generally there are public regulations on the handling of the solution and the handling of waste, so it is safe and easy to handle. A reagent was sought. Hereinafter, some of the test results for the uranin nitrate standard solution are shown.

以下、酢酸ウラニル蛍光法の手順を、硝酸ウラニン標準液を試薬として行なった場合についての試験結果の一部を示す。   Hereinafter, a part of test results in the case where the procedure of the uranyl acetate fluorescence method is performed using a uranine nitrate standard solution as a reagent is shown.

(1)硝酸ウラニン標準液+酢酸による試験
硝酸ウラニン標準液(2ml)に酢酸(0.05ml)を添加したものに試料を浸し、湯煎(50℃半日)し、一晩放置後、水洗浄し発光を確認した。
結果、発光が確認できたが微弱であった。硝酸によりゲルが流出してしまった可能性がある。
(1) Test with uranium nitrate standard solution + acetic acid Soak the sample in a solution of acetic acid (0.05 ml) in uranium nitrate standard solution (2 ml), bath in a bath (50 ° C for half a day), leave overnight, and then wash with water. The luminescence was confirmed.
As a result, although luminescence was confirmed, it was weak. Nitric acid may have caused the gel to flow out.

(2)硝酸ウラニン標準液(NaOHにより中和)+酢酸による試験
硝酸ウラニン標準液(2ml)にNaOHを添加しPHを弱酸性とした後、酢酸0.1mlを添加して希釈したものに、試料を浸し、湯煎(50℃半日)し、一晩放置後、水洗浄し発光を確認した。
結果、骨材の周囲にはっきりとした発光が確認できた。発光した部分はアルカリシリカゲルが生成していると考えられる部分であり、低濃度の放射性溶液を試薬として酢酸ウラニル蛍光法が実現できることが確認できた。
(2) Uranine nitrate standard solution (neutralized with NaOH) + test with acetic acid After adding NaOH to the standard solution of uranium nitrate (2 ml) to make PH weakly acidic, 0.1 ml of acetic acid was added and diluted. The sample was immersed, bathed in water (50 ° C. for half a day), allowed to stand overnight, washed with water, and luminescence was confirmed.
As a result, clear luminescence was confirmed around the aggregate. The portion that emitted light is considered to be produced by alkali silica gel, and it was confirmed that the uranyl acetate fluorescence method can be realized using a low-concentration radioactive solution as a reagent.

以上の如く、硝酸ウラニン標準液等に弱アルカリ化工程及び希釈工程を経て得た希釈液を用いてもアルカリシリカゲルの存否の判定が可能であり、取扱いに公的規制が緩やかな比較的安全性の高い試薬と、本発明による判定装置を併用すれば、調査現場におけるアルカリシリカ反応の判定に伴う実用性が、法的にも安全性においても、より高いものとなる。   As described above, the presence or absence of alkaline silica gel can be determined even if the diluted solution obtained through the weak alkalinization and dilution steps is used for the uranium nitrate standard solution, etc. In combination with a high-reagent and a determination apparatus according to the present invention, the practicality associated with the determination of an alkali silica reaction at the investigation site becomes higher in terms of both legal and safety.
