Description
【０００１】[0001]
この考案は、地面を掘削しないで下水道用ヒューム管等を埋設する推進工法の 施工の際に使用する反力板に関するものである。 The present invention relates to a reaction plate used for construction of a propulsion method in which a fume pipe for sewerage is buried without excavating the ground.
【０００２】[0002]
現在市街地など、埋設部全長に亘って地面を掘削することに支障がある場合に は推進工法が採られている。 Currently, the propulsion method is used when there is a problem in excavating the ground over the entire length of the buried part, such as in urban areas.
【０００３】 第１図は、現在一般に行なわれている小口径管推進工法の説明図で、先ず最小 限の大きさの円形の立坑ａを掘削し、周囲にライナープレート山囲ｂを施し、小 口径管埋設側とは反対側にコンクリート製擁壁ｃを構築してその内側に油圧ジャ ッキｄを設置し、この油圧ジャッキｄによりヒューム管ｅを接続し乍ら次々に押 し込んで行く。[0003] Fig. 1 is an explanatory view of a small-diameter pipe propulsion method that is generally used at present. First, a circular vertical shaft a having a minimum size is excavated, and a liner plate mountain b is provided around the shaft to make a small shaft. A concrete retaining wall c is constructed on the side opposite to the side where the caliber pipe is embedded, a hydraulic jack d is installed inside the concrete retaining wall c, and the fume pipe e is connected by this hydraulic jack d and pushed in one after another. .
【０００４】 そして、埋設工事が完了したら、擁壁ｃを削岩機で破壊し、埋め戻しを行った 後ライナープレート山囲を抜いている。After the burial work is completed, the retaining wall c is destroyed by a rock drilling machine and backfilled, and then the liner plate mountain surround is removed.
【０００５】[0005]
上記のように、従来の小口径管推進工法ではコンクリート製擁壁ｃの構築及び その撒去に日数を要するため、工事期間が長くなるという問題があった。そこで この考案は、この工事期間の短縮並びに資材及び経費の削減に有用な部材を提供 することを課題とするものである。 As described above, the conventional small-diameter pipe propulsion method has a problem that the construction period becomes long because it takes days to construct and remove the concrete retaining wall c. Then, this invention makes it a subject to provide the member useful for shortening this construction period and material and cost.
【０００６】[0006]
この考案は上記の課題を解決するためになされたもので、前面を平面とし、背 面を立坑のライナープレート山囲の内面に合わせた弧面とし、且つ内部に仕切壁 状に適数枚の補強パネルを設けて中空ブロックを構成し、前記補強パネルの数枚 の上部に吊孔を設け、この吊孔を設けた部分が露出するように上面板に窓を形成 すると共に、この窓から内部に浸水しないように中空ブロック内に閉鎖壁を設け たものである。 This invention was made in order to solve the above-mentioned problems.The front surface is a flat surface, the back surface is an arc surface that matches the inner surface of the liner plate mountain of the shaft, and a suitable number of partition walls are formed inside. A reinforcing block is provided to form a hollow block, a suspension hole is provided at the upper part of the reinforcement panel, and a window is formed on the top plate so that the portion where the suspension hole is provided is exposed. A closed wall is provided inside the hollow block so that it will not be flooded.
【０００７】[0007]
立孔内に本案品を置くだけで直ちに従来の擁壁と同様の機能をもつものが得ら れる。そして上面には突出物がないので、必要に応じて２段重ねすることができ る。また中空ブロック内には浸水の虞れがないので、工事終了後、浸水により重 くなることがない。 By simply placing the product in the vertical hole, a product with the same function as a conventional retaining wall can be obtained immediately. And since there is no protrusion on the top surface, it can be stacked in two stages if necessary. In addition, since there is no risk of flooding inside the hollow block, it will not become heavy due to flooding after the completion of construction.

図２はこの考案の実施例の平面図、図３は一部を截断した同正面図、図４はＡ −Ａ線断面図で、Ｘは前面１を平面とし、背面２を立坑のライナープレート山囲 ｂの内面に合わせた弧面とし、且つ内部に仕切壁状に適数枚の補強パネル３を設 けた金属板製の中空ブロックである。 2 is a plan view of an embodiment of the present invention, FIG. 3 is a partially cutaway front view of the same, and FIG. 4 is a sectional view taken along the line A-A in which X is a front surface 1 and a back surface 2 is a shaft liner plate. It is a hollow block made of a metal plate, which has an arc surface matching the inner surface of the mountain wall b and has a proper number of reinforcing panels 3 in the form of partition walls inside.
【０００９】 そして、この中空ブロックＸの左右の２枚の補強パネル３，３の上部にはそれ ぞれ吊孔４，４を設け、そしてこの吊孔４，４を設けた部分が露出するように、 上面板５に窓６，６を形成すると共に、この窓６，６から内部に浸水しないよう に中空ブロック内に逆かまぼこ状の閉鎖壁７，７を設けたものである。Then, hanging holes 4 and 4 are provided in the upper portions of the two reinforcing panels 3 and 3 on the left and right of the hollow block X, and the portions where the hanging holes 4 and 4 are provided are exposed. In addition, the windows 6 and 6 are formed in the top plate 5, and the inverted semi-cylindrical closing walls 7 and 7 are provided in the hollow block so as to prevent water from invading the windows 6 and 6.
【００１０】 次にその使用法について説明すると、本案品を使用する推進工法は、立坑を掘 削してライナープレート山囲ｂを設けることは従来工法と同様であるが、従来の コンクリート製擁壁ｃを構築する代りに、本案中空ブロックＸをクレーンやチエ ーンブロックを使用して立坑ａ内に垂下して、従来、擁壁ｃを設けていた位置に 設置し、油圧ジャッキｄを設置すれば、直ちにヒューム管の押し込み埋設工事を 施工出来る状態となる。なお、本案中空ブロックは上面には何も突出していない ので、必要に応じて２段重ねにすることができる。Explaining how to use it, the propulsion method using this product is similar to the conventional method in that the shaft is excavated to provide the liner plate mountain wall b, but the conventional concrete retaining wall Instead of constructing c, the hollow block X of the present invention is hung in a shaft a using a crane or a chain block, installed at a position where a retaining wall c was conventionally installed, and a hydraulic jack d is installed. Immediately, the fume pipe can be pushed and buried. In addition, since the hollow block of the present invention does not project anything on the upper surface, it can be stacked in two stages if necessary.
【００１１】[0011]
本の考案品を使用することにより従来のコンクリート製擁壁ｃの構築、撤去に 要した工事日数が短縮され、推進工法の工期の短縮に貢献するところ大である。 また、従来工法のようにコンクリート廃材が出ず、しかもコンクリート壁２回分 の費用で本案品１基を製造することができるばかりでなく、何回でも使用し得る ので、経費の大巾な削減となる。 By using the device of the present invention, the number of construction days required to construct and remove the conventional concrete retaining wall c is shortened, which greatly contributes to the reduction of the construction period of the propulsion method. Moreover, unlike the conventional method, concrete waste is not generated, and moreover, not only can one product of the present invention be manufactured at the cost of two concrete walls, but it can be used any number of times.
