【考案の詳細な説明】
この考案は例えば荷重条件等の変化により改築ないし修
復をよぎなくされる既設カルバートを簡単に修復する補
強構造に関するものである。[Detailed Description of the Invention] This invention relates to a reinforcing structure for easily restoring an existing culvert, which cannot be reconstructed or repaired due to changes in load conditions, for example.
既設のカルバートが改築あるいは大修復をよぎなくされ
るケースとして、主に永年使用による脆弱化と新規なも
のでも荷重条件の増大によりその強度を十分に達し得な
い場合とが考えられる。Cases in which existing culverts are forced to undergo renovation or major repair are mainly considered to be cases where they have become brittle due to long-term use, and cases where even new culverts cannot reach their full strength due to increased load conditions.
このような場合、従来においては当該カルバートをそっ
くり取り替えるとか、必要な箇所だけを改築するとか、
あるいはコンクリートを打設して補強するなどの手段を
とっていた。In such cases, conventional methods include replacing the culvert in its entirety or renovating only the necessary parts.
Alternatively, they took measures such as pouring concrete and reinforcing it.
しかし、上記手段はいずれの場合もその工事が新規工事
とほぼ同様かそれ以上に大がかりとなり工期、工費等に
おける損失が非常に多かった。However, in any case with the above methods, the construction work was almost as large as new construction work, or even more extensive, resulting in very large losses in terms of construction time and construction costs.
この考案は上記の事情に鑑みてなされたもので、その目
的とするところは既設カルバートの内壁面を工場で規格
生産された補強板で覆いかつ補強板と既設カルバート間
にモルタルを注入して一体化することにより、強度不足
や破損箇所など問題のある既設カルバートを修復補強す
ることにある。This idea was devised in view of the above circumstances, and its purpose was to cover the inner wall surface of the existing culvert with a reinforcing plate produced to a standard at the factory, and to inject mortar between the reinforcing plate and the existing culvert to form an integrated structure. The aim is to repair and reinforce existing culverts that have problems such as insufficient strength or damaged areas.
以下図面に基いてこの考案の一実施例を詳細に説明する
。An embodiment of this invention will be described in detail below based on the drawings.
第１図は補強板１の全体形状を示すもので、この補強板
１は両側壁２，２と天井壁３の一体成形されたもので、
この形状は本実施例では既設カルバート４（第２図参照
）の内壁面５の縮少相似形として成形した。FIG. 1 shows the overall shape of the reinforcing plate 1. This reinforcing plate 1 is integrally formed with both side walls 2, 2 and a ceiling wall 3.
In this embodiment, this shape was formed to resemble the reduced inner wall surface 5 of the existing culvert 4 (see FIG. 2).
なおこの補強板１の構造はプレキャスト方式によって成
形されたものである。Note that the structure of this reinforcing plate 1 is molded by a precast method.
また補強板１の両側壁２，２の下端は脚２ａ、２ａ構造
に成形されており、この脚２ａ、２ａにより既設カルバ
ート４内での安定設置及び補強板１と既設カルバート４
の内壁面５との間隙部６を形成するようにしている。Further, the lower ends of both side walls 2, 2 of the reinforcing plate 1 are formed into a structure of legs 2a, 2a, and these legs 2a, 2a allow for stable installation within the existing culvert 4 and between the reinforcing plate 1 and the existing culvert 4.
A gap 6 is formed between the inner wall surface 5 and the inner wall surface 5.
またこの脚２ａ、２ａは、補強板１の脱型後゛、あるい
は運搬時の安定支承に使用でき便利である。Further, the legs 2a, 2a can be conveniently used for stable support after the reinforcing plate 1 is demolded or during transportation.

-9 is the joint metal fitting, and -9 is the anchor reinforcing bar.
上記の如く成形された補強板１は第２図のように既設カ
ルバート４の内部に搬入設置され、間隙部６にグラウト
ホール７・・・・・・より充填するモルタル１０で一体
化して既設カルバート４の補強を行う。The reinforcing plate 1 formed as described above is carried and installed inside the existing culvert 4 as shown in FIG. Perform reinforcement in step 4.
ところで上記補強板１は既設カルバート４の内空面積の
大小にもよるが、一般には相当な重量となるので既設カ
ルバート４内部での搬送は図に示すような搬送車１１に
よって行なう。By the way, the reinforcing plate 1 generally has a considerable weight, although it depends on the size of the inner space area of the existing culvert 4, and therefore, it is transported inside the existing culvert 4 by a transport vehicle 11 as shown in the figure.
また既設カルバート４の床部１２は前記搬送車１１及び
レール等を撤去した後、補強板１の両側壁２，２の内側
に露出させたアンカー鉄筋９・・・・・・を水平に伸し
これと床板部１２に配設するアンカー鉄筋１３と溶着連
結し、最終的にコンクリート１４を打設して仕上げる。Furthermore, after removing the transport vehicle 11 and the rails, etc., the floor section 12 of the existing culvert 4 is constructed by horizontally extending the anchor reinforcing bars 9 exposed inside the both side walls 2 of the reinforcing plate 1. This is welded and connected to the anchor reinforcing bars 13 disposed on the floor plate portion 12, and finally concrete 14 is poured to finish.
第３図は既設カルバート４の長平方向の補強状態及び補
強板１の搬入要領を示したものである。FIG. 3 shows the reinforcing state of the existing culvert 4 in the longitudinal direction and the procedure for carrying in the reinforcing plate 1.
この図のように補強板１は、短ユニット成形されている
ので既設カルバート４の上部に補強板１が搬入し得る大
きさの口部１５を開けるのみで目的は十分達成できる。As shown in this figure, since the reinforcing plate 1 is formed into a short unit, the purpose can be sufficiently achieved by simply opening an opening 15 large enough to allow the reinforcing plate 1 to be carried in the upper part of the existing culvert 4.
しかして搬入、された補強板１は最奥部より順次口部１
５方向へ一体化されて来て最終に口部１５の一体化によ
り完了する。However, the reinforcing plate 1 that was carried in was sequentially placed at the opening 1 from the deepest part
They are integrated in five directions, and are finally completed by integrating the mouth portion 15.
なお上記実施例では既設カルバート４にほぼ四角なもの
を掲げ説明したが、−その他どのような形状をした既設
カルバートであっても同様にして構成することができる
。In the above embodiment, the existing culvert 4 is described as being approximately square; however, any other existing culvert having any shape may be constructed in the same manner.
