Description

本発明は、構造物の補修方法及びその補修装置にかかり、特に内部にひび割れを有するコンクリート構造物の補修方法に関するものである。
The present invention relates to a structure repair method and a repair apparatus therefor, and more particularly to a method for repairing a concrete structure having a crack inside.

従来より、例えば、表裏面あるいは左右、上下端面に貫通するひび割れを有するコンクリート構造物の補修方法及びその補修装置は各種存在している。 Conventionally, for example, there are various repair methods and repair devices for concrete structures having cracks penetrating the front and back surfaces, left and right, and upper and lower end surfaces.

例えば、特開平9-209577号公報には、コンクリートクラックの補修方法及びその装置が示されており、その内容としては、表裏に貫通したひび割れを対象とし、そしてひび割れ内を吸引する吸引部と補修材料供給部を表裏に装着する構造とされ、補修材料は液体状で供給部基材に含浸されており，補修材料を供給部からひび割れ空間内に吸引する構成が示されている。 For example, Japanese Laid-Open Patent Publication No. 9-209577 discloses a repair method and apparatus for concrete cracks, the contents of which are targeted for cracks penetrating through the front and back, and a suction part for repairing inside the cracks and repair. The structure is such that the material supply part is mounted on the front and back, the repair material is in liquid form and impregnated in the supply part base material, and the structure in which the repair material is sucked into the crack space from the supply part is shown.

また、特開平10-102789号公報には、漏水コンクリートクラックの補修装置及びその施工方法が示され、表裏に貫通し水分が充満したひび割れ（漏水をともなう）を対象とし、該ひび割れ内を吸引により水分除去とひび割れ内部の減圧を行い、当該ひび割れ内部に補修材料（親和性ポリウレタン樹脂系）を加圧または負圧による自然流入で注入する構造が示されている。 Japanese Patent Laid-Open No. 10-102789 discloses a leaky concrete crack repairing device and its construction method, and is intended for cracks (with water leaks) penetrating the front and back and filled with moisture, and the inside of the cracks is sucked. A structure is shown in which moisture is removed and the pressure inside the crack is reduced, and a repair material (affinity polyurethane resin system) is injected into the crack by natural inflow by pressurization or negative pressure.

さらに、特開2002-4589号公報には、コンクリート構造物における止水剤の注入工法および装置が示され、ひび割れ等の間隙内の空気・水を真空発生装置で強制吸引し、該間隙に通じる他の部分から補修材を注入する構造が、そして吸引器具として半球状殻体，長尺箱形殻体，ベル形殻体を用いる構造が示されている。 Furthermore, Japanese Patent Laid-Open No. 2002-4589 shows a method and apparatus for injecting a water-stopping agent in a concrete structure, and forcibly sucks air and water in a gap such as a crack with a vacuum generator and leads to the gap. A structure for injecting a repair material from another part and a structure using a hemispherical shell, a long box-shaped shell, and a bell-shaped shell as a suction device are shown.

また、特開2002-357000号公報には、コンクリート構造物の補修方法および補修具が示され、マイクロスコープで欠陥検出を行い，その欠陥部周囲を気密シートでシールし、補修具の一方に真空吸引ノズルを、他方に補修材料（硬化樹脂）注入ノズルを取り付け、真空吸引とともに注入を行う構造が示されている。 Japanese Patent Laid-Open No. 2002-357000 discloses a repair method and a repair tool for a concrete structure, which detects a defect with a microscope, seals the periphery of the defect with an airtight sheet, and vacuums one of the repair tools. A structure is shown in which a suction nozzle is attached to a repair material (cured resin) injection nozzle on the other side and injection is performed together with vacuum suction.

しかしながら、前記従来の技術は、いずれもひび割れ内を吸引する吸引部と、補修材料を供給する補修材料供給部とが分離されているため、全体として補修すべきコンクリート構造物に対する補修装置の設置が煩雑となるばかりでなく，複数箇所での注入操作を要するため，作業中の各種操作が複雑となるなどの課題があった。
特開平9-209577号公報特開平10-102789号公報特開2002-4589号公報特開2002-357000号公報 However, in each of the conventional techniques, since the suction part that sucks the inside of the crack and the repair material supply part that supplies the repair material are separated from each other, it is possible to install a repair device for the concrete structure to be repaired as a whole. In addition to being complicated, there are problems in that various operations during work are complicated because injection operations are required at a plurality of locations.
Japanese Patent Laid-Open No. 9-209577 Japanese Patent Laid-Open No. 10-102789 Japanese Patent Laid-Open No. 2002-4589 JP 2002-357000 A

かくして、本発明は前記従来の課題に対処すべく創案されたものであり、ひび割れ内を吸引する吸引部と、補修材料を供給する補修材料供給部が分離されておらず、もって全体として補修装置の設置が簡単に出来るばかりでなく，従来のように複数箇所での注入操作を必要とせず，作業中の各種操作もきわめて簡単に行え、しかも、微細なひび割れに対しても確実な注入が可能となり，補修の大幅な品質向上が図られ、また加圧による注入を真空注入に代えることで，構造物への負荷を低減することも出来、かつ注入孔数を１箇所にすることにより、補修工事の迅速化や省力化が図られ、ひび割れ内もスムーズに乾燥するため，注入剤の浸透性，接着性もより向上し、さらに注入孔と吸引孔との共用により，補修装置の設置が簡易で，一箇所での注入操作ができるため、補修工事のさらなる迅速化，省力化が図れるとの優れた利点を有するひび割れ構造物の補修方法を提供することを目的とするものである。
Thus, the present invention was devised to cope with the above-described conventional problems, and the suction part that sucks the inside of the crack and the repair material supply part that supplies the repair material are not separated, and thus the repair device as a whole. In addition to being easy to install, there is no need for multiple injection operations as in the past, and various operations during operation can be performed very easily, and reliable injection is possible even for fine cracks. Therefore, the quality of repairs can be greatly improved, and the load on the structure can be reduced by replacing the injection by pressurization with vacuum injection, and the repair is done by reducing the number of injection holes to one. Speeding up work and saving labor, and the inside of the crack is dried smoothly, so that the permeability and adhesiveness of the injection agent are further improved, and the repair device can be easily installed by sharing the injection hole and suction hole. And one place Since capable of injecting operation is further faster repair work, it is an object to provide a method of repairing a crack structure having advantages of labor saving can be achieved.

In addition, it is possible to reduce the load on the structure by replacing the injection by pressurization with vacuum injection, and, as described above, the number of injection holes is one. In addition, the repair work is speeded up and labor-saving, and the inside of the crack is dried smoothly, so that the permeability and adhesion of the injection agent are further improved, and as described above, the repair is achieved by sharing the injection hole and suction hole. Equipment setup In but simple, achieved since it is injection operations in one place, further acceleration of repair work, an excellent effect of labor saving can be achieved.

以下、本発明を図に示す実施例に基づいて説明する。
まず、本発明によるひび割れを有する構造物のひび割れ１の補修方法につき説明する。
例えば、表裏面の端面に貫通する複数のひび割れ１・・・を有するコンクリート構造物２において、ひび割れ１の内部を吸引し、かつひび割れ１の内部に補修部材を注入すべき適切なひび割れ箇所を一箇所選択する。 Hereinafter, the present invention will be described based on embodiments shown in the drawings.
First, the repair method of the crack 1 of the structure which has a crack by this invention is demonstrated.
For example, in a concrete structure 2 having a plurality of cracks 1 penetrating through the end surfaces of the front and back surfaces, the inside of the crack 1 is sucked, and an appropriate crack location where a repair member should be injected into the crack 1 is identified. Select a location.

ここで、該ひび割れ箇所の選択に関しては、何ら限定されるものではないが、通常は図１から理解されるように、コンクリート構造物２の上面部位に存する一箇所のひび割れ箇所が選択される。
なぜなら、後述する補修装置３の構成部材であるひび割れ補修操作部４の設置が上面に置くだけでよく比較的容易に行えるからである。
しかしながら、本発明では前記した上面部位のみならず、図２に示すように、コンクリート構造物２の左右側面部位、あるいはコンクリート構造物２の斜めに傾いた斜面部位でも後述するひび割れ補修操作部４の設置ができる特徴がある。 Here, the selection of the cracked portion is not limited in any way, but usually one cracked portion existing in the upper surface portion of the concrete structure 2 is selected as understood from FIG.
This is because the crack repair operation unit 4 that is a constituent member of the repair device 3 to be described later can be installed on the upper surface relatively easily.
However, in the present invention, not only the above-described upper surface portion, but also the left and right side portions of the concrete structure 2 or the obliquely inclined slope portion of the concrete structure 2 as shown in FIG. There is a feature that can be installed.

なお、補修装置３の構成につき説明すると、該補修装置３は、ひび割れ補修操作部４と、該ひび割れ補修操作部４が設置されるコンクリート構造物２のひび割れ１の箇所を除いて、コンクリート構造物２を密閉、すなわちコンクリート構造物２のひび割れ開口を密閉してシーリングするシーリング部５とを有して構成される。
前記シーリング部５の構成については、何ら限定されず、いかなる構造で、いかなる方法でシーリングするのもよい。例えば、シート状のシーリング部材でコンクリート構造物の全体を密閉すべく被覆した構成でもよい。また、液体状のシーリング材を前記コンクリート構造物２のひび割れ開口に塗布し、もって密閉するタイプでも構わない。 The configuration of the repair device 3 will be described. The repair device 3 is a concrete structure except for a crack repair operation unit 4 and a crack 1 part of the concrete structure 2 in which the crack repair operation unit 4 is installed. 2 is sealed, that is, it has a sealing portion 5 that seals and seals the crack opening of the concrete structure 2.
The configuration of the sealing part 5 is not limited at all, and any structure and any method may be used for sealing. For example, the structure which coat | covered so that the whole concrete structure might be sealed with the sheet-like sealing member may be sufficient. Further, a liquid sealing material may be applied to the crack opening of the concrete structure 2 and hermetically sealed.

次に、ひび割れ補修操作部４は、図から理解されるように、所定箇所のひび割れ１を覆う、略ドーム状あるいは略方形状をなす覆い部６を有する。
この覆い部６の形状については略ドーム状あるいは略方形状をなすとしたが、この様な形状に限定されるものではなく、内部に後述する密閉操作空間部７が形成できるものであれば、その形状は問わない。 Next, the crack repair operation part 4 has the cover part 6 which makes the substantially dome shape or a substantially rectangular shape which covers the crack 1 of a predetermined location so that a figure may understand.
The shape of the cover portion 6 is substantially dome-shaped or substantially square-shaped, but is not limited to such a shape, as long as a sealing operation space portion 7 described later can be formed therein, The shape does not matter.

また、覆い部６の材質についても何ら限定されるものではなく、耐久性があり、比較的軽量な部材であれば好ましい。
しかして、所定のひび割れ１の箇所は、覆い部６により覆われて、内部にひび割れ１の箇所と連通する密閉操作空間部７を有するものとなる。 Moreover, the material of the cover part 6 is not limited at all, and a durable and relatively light member is preferable.
Thus, the location of the predetermined crack 1 is covered with the cover portion 6 and has a sealed operation space portion 7 communicating with the location of the crack 1 inside.

次に、図示するように、前記密閉操作空間部７には、いわゆる吸引部となる真空ポンプ８に連通する吸引管１５が挿入されて内部のひび割れ１と連通しており、該真空ポンプ８を作動することにより、前記密閉操作空間部７内、さらにはその密閉操作空間部７の中に位置するひび割れ１に通ずる吸入孔９を介してコンクリート構造物２の内部に存する全てのひび割れ１内が真空状態とされるものとなる。
なお、覆い部６は、密閉操作空間部７が真空状態になると、強固にコンクリート構造物２に吸着する。よって覆い部６の取り付けについては何らの取り付け部材も要しない、あるいは取り付け部材が必要とされたとしても比較的簡単な取り付け部材ですむとのメリットがある。 Next, as shown in the drawing, a suction tube 15 communicating with a vacuum pump 8 serving as a so-called suction portion is inserted into the sealing operation space portion 7 so as to communicate with the internal crack 1. By operating, the inside of the cracking operation space 7 and the inside of all the cracks 1 existing in the concrete structure 2 through the suction holes 9 leading to the cracking 1 located in the sealing operation space portion 7 are caused. It becomes a vacuum state.
In addition, the cover part 6 will adsorb | suck to the concrete structure 2 firmly, when the sealing operation space part 7 will be in a vacuum state. Therefore, there is an advantage that no attachment member is required for the attachment of the cover part 6 or that a relatively simple attachment member is required even if an attachment member is required.

従って、前記したように、コンクリート構造物２の左右側面部位（図２参照）、あるいはコンクリート構造物２の斜めに傾いた斜面部位でもひび割れ補修操作部４の設置ができるとの効果を存する。
また、密閉操作空間部７内には、前記密閉操作空間部７及び密閉操作空間部７に連通するひび割れ１内の真空状態を検知する圧力センサ１０が設けられている。 Therefore, as described above, there is an effect that the crack repair operation unit 4 can be installed even on the left and right side portions (see FIG. 2) of the concrete structure 2 or on the inclined slope portion of the concrete structure 2.
Further, a pressure sensor 10 that detects a vacuum state in the crack 1 that communicates with the sealing operation space portion 7 and the sealing operation space portion 7 is provided in the sealing operation space portion 7.

該圧力センサ１０の必要性は、前記密閉操作空間部７及び密閉操作空間部７に連通するひび割れ１内の真空状態をセンスすることにある。しかして、圧力センサ１０で密閉操作空間部７及び密閉操作空間部７に連通するひび割れ１内をいわゆる中真空（１０２乃至１０−１Ｐａ）に達したことを検知するのである。
この様に、完全な真空状態でなくとも、前記のように中真空の状態で充分な吸引作業が出来るものである。従って、完全な真空状態にするための時間と労力が軽減できるものとなる。 The necessity of the pressure sensor 10 is to sense the vacuum state in the crack 1 connected to the sealing operation space 7 and the sealing operation space 7. Accordingly, the pressure sensor 10 detects that the inside of the closed operation space portion 7 and the crack 1 communicating with the closed operation space portion 7 has reached a so-called medium vacuum (102 to 10-1 Pa).
In this way, even if it is not in a complete vacuum state, a sufficient suction operation can be performed in a medium vacuum state as described above. Therefore, the time and labor required to make a complete vacuum state can be reduced.

次に、符号１１は、ひび割れ１内に注入されるひび割れ補修材料であり、例えば蛍光エポキシ樹脂などが用いられる。
該ひび割れ補修材料１１は、所定のケース１２内に収納されており、該ケース１２内と前記密閉操作空間部７内とは注入管１３で連通され、該注入管１３を介して、ひび割れ補修材料１１が密閉操作空間部７及びひび割れ１内に注入されるものとなる。 Next, the code | symbol 11 is the crack repair material inject | poured in the crack 1, for example, a fluorescent epoxy resin etc. are used.
The crack repair material 11 is housed in a predetermined case 12, and the case 12 and the sealed operation space 7 are communicated with an injection pipe 13, and the crack repair material is passed through the injection pipe 13. 11 is injected into the sealed operation space 7 and the crack 1.

前述のようにひび割れ補修操作部を設置した後、真空ポンプ８を作動させて、密閉操作空間部７及びこれに連通するコンクリート構造物２内に連通するひび割れ１内を真空状態とする。
真空状態について、何ら数値上の限定はないが、例えば、中真空（１０２乃至１０−１Ｐａ）程度で構わないことはすでに述べたとおりである。
かかる中真空状態を圧力センサ１０で検知し、その状態が保持できるようにしておく。 After the crack repair operation part is installed as described above, the vacuum pump 8 is operated to make the inside of the crack 1 communicating with the sealed operation space part 7 and the concrete structure 2 communicating therewith a vacuum state.
There is no numerical limitation on the vacuum state, but as described above, for example, a medium vacuum (102 to 10-1 Pa) may be used.
Such a medium vacuum state is detected by the pressure sensor 10 so that the state can be maintained.

そして、密閉操作空間部７及びそれに連通するひび割れ１・・・が中真空状態になると、自動的にケース１２内からひび割れ補修材料１１を吸引し、密閉操作空間部７及びひび割れ１・・・内に注入されるものとなる。
そして、その注入動作は、真空状態にした吸入孔９によって行われるのである。すなわち、吸入孔９が注入孔１４の機能も果たすことになる。
Then, when the sealed operation space 7 and the crack 1 communicating therewith are in a medium vacuum state, the crack repair material 11 is automatically sucked from the case 12, and the closed operation space 7 and the crack 1. Will be injected.
And the injection | pouring operation | movement is performed by the suction hole 9 made into the vacuum state. That is, the suction hole 9 also functions as the injection hole 14.
