Description

本発明は、コンクリート構造体の表層部へ含浸材を浸透させるための浸透圧入装置及び浸透圧入方法に関する。   The present invention relates to an osmotic press-in apparatus and an osmotic press-in method for infiltrating an impregnating material into a surface layer portion of a concrete structure.

一般に、コンクリートの製造においては、コンクリートに適度の流動性を付与して密実なコンクリートの充填ができるようにするために、セメントの水和反応に必要な水量（水セメント比で２７％前後）の２倍以上（日本建築学会のコンクリート工事標準仕様書では上限として６５％が規定されている）の水量を混入させている。   In general, in the production of concrete, the amount of water required for cement hydration reaction (approx. 27% in terms of water-cement ratio) in order to give the concrete a proper fluidity and allow the concrete to be filled with dense concrete. Of water (65% is specified as the upper limit in the concrete construction standard specification of the Architectural Institute of Japan) is mixed in.

このため、余分な水の一部はコンクリートが固まる前にブリージング水等として逸出するが、かなりの量の水がコンクリート中に余剰水として残存するため、この余剰水が蒸発した後に空隙が残り、ポーラスなコンクリートが出来上がることになり、この空隙を通じて空気中の二酸化炭素やＳＯｘ、ＮＯｘ等の有害物質を含む雨水、飛来塩分等が侵入することになる。   For this reason, some of the excess water escapes as breathing water etc. before the concrete hardens, but a considerable amount of water remains as excess water in the concrete, so that voids remain after the excess water evaporates. Porous concrete will be completed, and rainwater containing air, carbon dioxide, SOx, NOx and other harmful substances will enter through this gap.

コンクリートの早期劣化現象の主な原因は上記のようなポーラスなコンクリートの製造にあり、このようなポーラスなコンクリートを使用したコンクリート構造物の早期劣化現象に対応するために、各種のコンクリート補修工法が試みられている。その中の代表的な工法に「表面被覆工」があり、この「表面被覆工」は、土木学会により、有機系被覆工（塗装工法、シート工法）、無機系被覆工（単層塗装工法、複層塗装工法、メッシュ工法）、表面含浸工（シラン系表面含浸工、珪酸リチウム系表面含浸工、珪酸ナトリウム系表面含浸工）、断面修復工（左官工法、吹付工法、充填工法）の４つに区分されている。   The main cause of the early deterioration phenomenon of concrete is the production of porous concrete as described above, and various concrete repair methods are used to deal with the early deterioration phenomenon of concrete structures using such porous concrete. Has been tried. Among them, there is a “surface coating method”, and this “surface coating method” is an organic coating method (painting method, sheet method), inorganic coating method (single layer coating method, Multi-layer coating method, mesh method), surface impregnation method (silane surface impregnation method, lithium silicate type surface impregnation method, sodium silicate type surface impregnation method), cross-section repair method (left plaster method, spraying method, filling method) It is divided into.

ところで、上記のような表面被覆工のうちの表面含浸工は、含浸効果を高めるために、刷毛塗り、ローラー刷毛塗り、吹付け、噴霧等によってコンクリート表層部に表面含浸材を浸透させているが、コンクリート組織が緻密であったり、表層部に多量の水分を含む場合には、含浸材の粘性を低下させたり、含浸時間を長くしても、必要な含浸深さを確保することができない。   By the way, the surface impregnation of the surface coating as described above has the surface impregnation material infiltrated into the concrete surface layer portion by brush coating, roller brush coating, spraying, spraying, etc. in order to enhance the impregnation effect. When the concrete structure is dense or the surface layer portion contains a large amount of moisture, the required impregnation depth cannot be ensured even if the viscosity of the impregnating material is lowered or the impregnation time is increased.

本発明は、上記のような従来の問題に鑑みなされたものであって、コンクリート構造物の表層部に含浸材を浸透させる場合に、コンクリート構造物のコンクリートの性状に影響されることなく、必要な含浸深さが確実に得られる浸透圧入装置及び浸透圧入方法を提供することを目的とする。   The present invention has been made in view of the conventional problems as described above, and is necessary without being affected by the properties of the concrete of the concrete structure when the impregnating material is infiltrated into the surface layer portion of the concrete structure.

超音波加振手段３０は、浸透圧入部２の各加振子用溝７内にそれぞれ着脱自在に装着される長方形板状の加振子３１と、加振子３１に配線３３を介して接続される加振子用電源３２とから構成されている。この場合、各加振子３１は、浸透圧入部２の本体部３の裏面５と面一となるように寸法が設定されている。加振子用電源３２の作動により、配線３３を介して各加振子３１を超音波振動させることにより、その振動が各加振子３１に接触する含浸材２８に伝達し、含浸材２８を介して含浸材２８に接触するコンクリート構造物３５の表層部３７に伝達し、含浸材２８の表層部２７への浸透が促進される。   The ultrasonic vibration means 30 includes a rectangular plate-shaped vibration element 31 that is detachably mounted in each vibration element groove 7 of the osmotic press-fitting portion 2, and a vibration element that is connected to the vibration element 31 via a wiring 33. And a pendulum power supply 32. In this case, the size of each vibrator 31 is set so as to be flush with the back surface 5 of the main body portion 3 of the osmotic press-fitting portion 2. By operating the vibrator power supply 32, each vibrator 31 is ultrasonically vibrated via the wiring 33, and the vibration is transmitted to the impregnating material 28 in contact with each vibrator 31 and impregnated via the impregnating material 28. This is transmitted to the surface layer portion 37 of the concrete structure 35 that contacts the material 28, and the penetration of the impregnated material 28 into the surface layer portion 27 is promoted.

本実施の形態においては、加振子３１に長方形板状のものを用いているが、この形状に限定されることなく、円形板状、ドーナツ板状等のものを使用してもよい。また、本実施の形態においては、浸透圧入部２の本体部３に３つの加振子３１を取り付けているが、２つ又は４つ以上の加振子を取り付けてもよい。複数の加振子を取り付ける場合には、複数の加振子が本体部３の全体に均一に散らばるように取り付けるのが好ましい。   In the present embodiment, a rectangular plate shape is used for the vibrator 31, but the shape is not limited to this shape, and a circular plate shape, a donut plate shape, or the like may be used. Moreover, in this Embodiment, although the three shakers 31 are attached to the main-body part 3 of the osmotic press-fit part 2, you may attach two or four or more shakers. When attaching a plurality of vibrators, it is preferable to attach the vibrators so that the plurality of vibrators are evenly dispersed throughout the main body 3.

次に、上記のように構成した本実施の形態による浸透圧入装置１の作用について説明する。
まず、コンクリート構造物３５の表面３６に浸透圧入装置１の浸透圧入部２の本体部３の裏面５側を対向させて、裏面５側の内側シール部材１２及び外側シール部材１３をコンクリート構造物３５の表面３６に接触させ、浸透圧入部２をコンクリート構造物３５の方向に押圧して、コンクリート構造物３５の表面３６と浸透圧入部２の本体部３との間に、内側シール部材１２及び外側シール部材１３によって周囲が囲まれた密閉された含浸材貯留空間１６を形成する。この場合、必要に応じて、予めコンクリート構造物３５の表面３６の凹凸をなくす処理を行い、含浸材貯留空間１６の密封性を高める。 Next, the operation of the osmotic press-fitting device 1 according to the present embodiment configured as described above will be described.
First, the back surface 5 side of the main body portion 3 of the osmotic press-fitting part 2 of the osmotic press-fitting device 1 is opposed to the surface 36 of the concrete structure 35, and the inner seal member 12 and the outer seal member 13 on the back surface 5 side are placed on the concrete structure 35. The inner surface sealing member 12 and the outer side between the surface 36 of the concrete structure 35 and the main body portion 3 of the osmotic press-fitting part 2 by pressing the osmotic press-fitting part 2 in the direction of the concrete structure 35. A sealed impregnating material storage space 16 surrounded by a seal member 13 is formed. In this case, if necessary, the surface 36 of the concrete structure 35 is preliminarily processed to remove the irregularities, thereby improving the sealing property of the impregnating material storage space 16.

そして、超音波加振手段３０の加振子用電源３２を作動させて、配線３３を介して各加振子３１を超音波振動させ、圧縮空気供給手段２０のコンプレッサー２１を作動させて、配管２２を介して内側シール部材１２と外側シール部材１３との間の空間１４内に圧縮空気１５を供給し、内側シール部材１２と外側シール部材１３と圧縮空気１５との協働により、浸透圧入部２の本体部３の裏面４とコンクリート構造物３５の表面３６との間に形成される含浸材貯留空間１６の周囲を完全にシールする。   Then, the vibration generator power source 32 of the ultrasonic vibration means 30 is operated to ultrasonically vibrate each of the vibration elements 31 via the wiring 33, the compressor 21 of the compressed air supply means 20 is operated, and the pipe 22 is connected. The compressed air 15 is supplied into the space 14 between the inner seal member 12 and the outer seal member 13 via the inner seal member 12 and the outer seal member 13 and the compressed air 15 in cooperation with each other. The periphery of the impregnating material storage space 16 formed between the back surface 4 of the main body 3 and the surface 36 of the concrete structure 35 is completely sealed.

そして、この状態で含浸材供給手段２５の含浸材供給源２６を作動させ、配管２７を介して浸透圧入部２の本体部３の裏面４側から含浸材を所定の圧力で吐出させ、含浸材貯留空間１６内に含浸材２８を充満させる。この場合、含浸材供給源２６から供給される含浸材２８の圧力とコンプレッサー２１から供給される圧縮空気１５の圧力とを等しくなるように調整することにより、含浸材貯留空間１６内から含浸材２８が漏出するのを防止する。   In this state, the impregnating material supply source 26 of the impregnating material supplying means 25 is operated, and the impregnating material is discharged at a predetermined pressure from the back surface 4 side of the main body portion 3 of the osmotic press-fitting portion 2 via the pipe 27. The storage space 16 is filled with the impregnating material 28. In this case, the impregnating material 28 is supplied from the impregnating material storage space 16 by adjusting the pressure of the impregnating material 28 supplied from the impregnating material supply source 26 and the pressure of the compressed air 15 supplied from the compressor 21 to be equal. Prevent leakage.

そして、浸透圧入部２をコンクリート構造物３５の表面３６に沿って所定の速度でスライドさせることにより、コンクリート構造物３５の表面３６の全体に含浸材２８が満遍なく均一に塗布されるとともに、コンクリート構造物３５の表層部３７に所定の深さまで含浸材２８が浸透されることになる。なお、図４中のａは含浸材２８の塗布済みのエリア、ｂは含浸材の塗布中のエリアを示している。   The osmotic press-fit portion 2 is slid along the surface 36 of the concrete structure 35 at a predetermined speed, whereby the impregnating material 28 is uniformly and uniformly applied to the entire surface 36 of the concrete structure 35, and the concrete structure The impregnating material 28 is infiltrated into the surface layer portion 37 of the object 35 to a predetermined depth. In FIG. 4, a indicates an area where the impregnating material 28 has been applied, and b indicates an area where the impregnating material is being applied.

上記のように構成した本実施の形態による浸透圧入装置にあっては、含浸材供給手段２０の含浸材供給源２６から含浸材２８を所定の圧力で含浸材貯留空間１６内に供給し、この含浸材貯留空間１６内の含浸材２８に超音波加振手段３０の加振子３１によって超音波振動を付与し、この振動を含浸材２８を介してコンクリート構造物３５の表層部３７に伝達させているので、含浸材２８を粘性の小さな適度なゾル状態に保つことができ、このゾル状態を保った含浸材２８をコンクリート構造物３５の表層部３７に浸透させることができる。   In the osmotic press-fitting device according to the present embodiment configured as described above, the impregnating material 28 is supplied into the impregnating material storage space 16 from the impregnating material supply source 26 of the impregnating material supply means 20 at a predetermined pressure. Ultrasonic vibration is applied to the impregnation material 28 in the impregnation material storage space 16 by the vibrator 31 of the ultrasonic vibration means 30, and this vibration is transmitted to the surface layer portion 37 of the concrete structure 35 through the impregnation material 28. Therefore, the impregnating material 28 can be maintained in an appropriate sol state having a small viscosity, and the impregnating material 28 maintained in the sol state can be permeated into the surface layer portion 37 of the concrete structure 35.

従って、コンクリート構造物３５の表層部３７に含浸材２８を効率良く浸透させることができるので、コンクリート構造物３５の表層部３７を良質の保護層に形成することができる。   Therefore, since the impregnating material 28 can be efficiently infiltrated into the surface layer portion 37 of the concrete structure 35, the surface layer portion 37 of the concrete structure 35 can be formed in a good quality protective layer.

また、含浸材貯留空間１６を、シール手段１１の内側シール部材１２と外側シール部材１３と圧縮空気１５との協働によって完全にシールしているので、含浸材貯留空間１６内から含浸材２８が漏出するのを確実に防止できることになる。
従って、含浸材２８の漏出分を考慮する必要はなく、含浸材２８の使用量を削減することができ、表面含浸工の施工費を削減することができる。 Further, since the impregnating material storage space 16 is completely sealed by the cooperation of the inner sealing member 12, the outer sealing member 13 and the compressed air 15 of the sealing means 11, the impregnating material 28 is introduced from the impregnating material storage space 16. It is possible to reliably prevent leakage.
Therefore, it is not necessary to consider the leakage of the impregnating material 28, the amount of the impregnating material 28 used can be reduced, and the construction cost of the surface impregnation work can be reduced.

さらに、コンクリート構造物３５の表面３６に沿って浸透圧入部２をスライドさせることにより、コンクリート構造物３５の全表層部３７に連続して含浸材２８を浸透させることができるので、表面含浸工の施工効率を大幅に高めることができる。   Furthermore, by sliding the osmotic press-fit portion 2 along the surface 36 of the concrete structure 35, the impregnating material 28 can be continuously infiltrated into the entire surface layer portion 37 of the concrete structure 35. Construction efficiency can be greatly increased.
