本考案は、下水用ボックスカルバートに関スルものであ
る。[Detailed Description of the Invention] The present invention relates to a box culvert for sewage.
ボックスカルバートは道路や鉄道、堤防などの下に設け
られる箱形断面の鉄筋コンクリート製暗渠であり、これ
を連接して下水路を形成する場合がある。A box culvert is a reinforced concrete culvert with a box-shaped cross section that is installed under roads, railways, embankments, etc., and may be connected to form a sewer channel.
下水路は一般に、僅かな一定勾配をもたせて形成される
ことが好ましい。It is generally preferred that the sewer channel be formed with a slight constant slope.
しかし、地勢によってはこの下水路の勾配を部分的に急
にせざるを得ない場合がある。However, depending on the terrain, it may be necessary to partially steepen the slope of this sewer.
このような場所の下水路においては、特に急勾配から緩
勾配に変化する水路上の部分では、水勢による浸蝕が著
しく、長期に亙る使用に耐えない。Sewers in such places, especially in the portions of the waterway where the slope changes from steep to gentle, are severely eroded by the force of the water and cannot withstand long-term use.
本考案はこのような問題を解決するための下水用ボック
スカルバートを提供するもので、その特徴とするところ
は、ボックスカルバート本体の内部底面に、該底面の一
側から他側にかけて、上記ボックスカルバート本体の長
手方向に対してほぼ直角に突条を設け、該突条の水流に
面する側を斜面とし、該突条を上記ボックスカルバート
本体に着脱可能に取付けたことにある。The present invention provides a box culvert for sewage to solve such problems, and its feature is that the box culvert is attached to the inner bottom surface of the box culvert body from one side to the other side of the bottom surface. A protrusion is provided approximately at right angles to the longitudinal direction of the main body, the side of the protrusion facing the water flow is sloped, and the protrusion is removably attached to the box culvert body.
以下図面に示した実施例を参照しながら本考案を説明す
る。The present invention will be described below with reference to embodiments shown in the drawings.
本考案に係る下水用ボックスカルバート１は、その内部
底面２に突条３を配設したものである。The sewage box culvert 1 according to the present invention has protrusions 3 arranged on its internal bottom surface 2.
この突条３は第２図に示したように一方の側面から他方
の側面に差渡して連続的に配設し、第１図に示したよう
に前面４を傾斜させ、後面５をほは゛垂直に形成してい
る。The protrusions 3 are arranged continuously from one side to the other as shown in FIG. It is formed vertically.
この突条３の高さは少なくとも水勢を抑制するに十分な
高さでなければいけないが、たとえば水量が多い場合は
ど高く、勾配が急なほど高くするなど適宜にその高さを
決定する必要があり、一般には、水路の高さの１０〜４
０％位にすることが好ましい。The height of this protrusion 3 must be at least high enough to suppress the water force, but it is necessary to determine the height appropriately, for example, if the amount of water is large, the height should be higher, and if the slope is steeper, the height should be higher. Generally, the height of the waterway is 10 to 4
It is preferable to set it to around 0%.
本考案に係る下水用ボックスカルバート１は下水路にお
ける急勾配個所に設置される。The sewage box culvert 1 according to the present invention is installed at a steeply sloped part of a sewage channel.
下水路を流れる水は、このボックスカルバート１内を通
過する際に、突条３に当り、その前面４の斜面に沿って
流れたのち、上方および左右に飛び散るとともに後面５
の垂直面をも流れ、落下する際に渦流となり、この突条
３で水勢が抑制され、流速が減じる。When water flowing through the sewer channel passes through this box culvert 1, it hits the protrusion 3, flows along the slope of the front surface 4, and then scatters upward and to the left and right, as well as to the rear surface 5.
The water also flows on the vertical plane of the water, and as it falls, it becomes a vortex, and the water force is suppressed by the ridges 3, reducing the flow speed.
また、突条３は本体６と別に形成され、第３図に示すよ
うに、この突条３をボルト７等で本体６に着脱可能に取
り付けた。Further, the protrusion 3 is formed separately from the main body 6, and as shown in FIG. 3, the protrusion 3 is removably attached to the main body 6 with bolts 7 or the like.
なお、突条３は、１のカルバート１内で１個所に限らず
、数個所に設けてもよく、また、種々の高さ、巾および
傾斜面をもつものを適宜に組合せて設けてもよい。Note that the protrusions 3 are not limited to one location in one culvert 1, but may be provided at several locations, or may be provided in an appropriate combination of various heights, widths, and slopes. .
本考案に係る下水用ボックスカルバートは、上記したよ
うに、そこを流れる水勢を減少させることができるので
、これを急勾配の個所に配設することにより、それに続
く緩勾配の個所のボックスカルバートにおける水路上の
部分の浸蝕を防止することができ、下水路の耐久性を高
めることができる。As mentioned above, the sewage box culvert according to the present invention can reduce the water force flowing through it, so by installing it at a steep slope, the box culvert at the subsequent gentle slope Erosion of the portion above the waterway can be prevented and the durability of the sewerage waterway can be increased.
また、本考案はボックスカルバートと別に形成した突条
をカルバート本体に着脱可能に取付けるようにしたから
、該突条をカルバート本体に一体成形する場合に比べて
、型わくの構造が簡単になり、その取付けおよび取外し
の作業が煩雑でなく、しかも突条の品質も一定となり、
したがって突条の耐久性が高まり、長期の使用に耐え経
済的に極めて有利である。In addition, in the present invention, the protrusion formed separately from the box culvert is removably attached to the culvert body, so the structure of the mold frame is simpler than when the protrusion is integrally molded to the culvert body. The installation and removal work is not complicated, and the quality of the protrusions remains constant.
Therefore, the durability of the protrusion is increased, and it can withstand long-term use and is economically extremely advantageous.
さらに設置される下水用ボックスカルバートの勾配に応
じて、種々の高さ、中および前面の傾斜角をもつ突条を
適当数、上記カルバート本体に取付けることができる。Further, depending on the slope of the sewage box culvert to be installed, an appropriate number of protrusions having various heights and angles of inclination in the middle and front can be attached to the culvert body.
