Description
本発明は、例えば道路や住宅の脇に敷設されてなる既設水路の補修に使用される水路用コンクリート製インバート部材及び該部材を使用して既設水路を補修した既設水路の補修工法に関するものである。
The present invention relates to a concrete invert member for a water channel used for repairing an existing water channel laid on the side of, for example, a road or a house, and a repair method for an existing water channel using the member to repair the existing water channel. .
従来、特開平10−140641号公報に記載されているように、いわゆる水路を形成する可変側溝については多くの特許出願がなされ、多くの特許も取得されている。 Conventionally, as described in JP-A-10-140641, many patent applications and many patents have been obtained for variable side grooves forming so-called water channels.
しかしながら、例えば、都市部に存在する既設の家庭用排水などを流す既設水路の状況を考察すると、該既設水路は、U字溝で形成されていたり、単なる土留めにより形成されていたり、自然の谷川などで形成されていたりしている。 However, for example, when considering the situation of an existing water channel that drains existing household drainage in urban areas, the existing water channel is formed by a U-shaped groove, formed by simple earth retaining, It is formed in Tanikawa.
これらの既設水路は、通常の家庭用排水を流すためのものであり、普段はほとんど水の流れを有しないのが現状である。従って、長い間、雨が降らない場合には、この既設水路に、ゴミや土砂が堆積し、悪臭が発生したり、雑草が繁殖したりしてきわめて不衛生になりがちである。 These existing water channels are for flowing ordinary household wastewater, and usually have almost no water flow. Therefore, if it does not rain for a long time, garbage and earth and sand accumulate in this existing water channel, and bad odor is generated and weeds tend to grow, which tends to be extremely unsanitary.
ここで、近年では前記のような既設水路の補修が叫ばれているが、これら前記のような既設水路を改修、補修したくとも、当該既設水路は民家の隙間などをぬって形成されており、このため重機などが進入できず、補修工事がきわめて困難であったのである。
Here, in recent years, the repair of the existing water channels as described above has been screamed. However, even if the existing water channels as described above are to be repaired or repaired, the existing water channels are formed through gaps in private houses. For this reason, heavy machinery could not enter and repair work was extremely difficult.
かくして、本発明は前記従来からの課題を解決するために創案されたもので、民家の隙間などをぬって形成されており、このため重機などが進入できず、補修工事がきわめて困難な箇所に形成されている既設水路であり、しかも、通常の家庭用排水を流すためのもので、普段はほとんど水の流れを有しない、従って、長い間、雨が降らない場合には、ゴミや土砂が堆積し、悪臭が発生したり、雑草が繁殖したりしてきわめて不衛生になりがちとなる既設水路につき、補修が容易で、カーブする箇所でも簡単に補修ができ、少量の流れであってもスムーズな流れを作ることができ、さらには勾配がある既設水路形成箇所において、逆の勾配側に流れを作ることができる水路用コンクリート製インバート部材及び該部材を使用して既設水路を補修した既設水路の補修工法を提供することを目的とするものである。
Thus, the present invention was created to solve the above-mentioned conventional problems, and is formed through a gap in a private house, etc., so that heavy machinery or the like cannot enter and repair work is extremely difficult. It is an existing water channel that is formed, and is intended for the flow of normal household wastewater. Normally, it has little flow of water. Therefore, if it does not rain for a long time, dirt and earth and sand are collected. It is easy to repair existing waterways that tend to become very unsanitary due to accumulation, bad odor, and weeds breeding, and can be easily repaired even in curved areas. A concrete invert member for a waterway that can create a smooth flow and that can create a flow on the opposite slope side at an existing waterway formation site with a slope, and repair the existing waterway using the member. And it is an object to provide a repairing method of the existing waterways.

If the invert member made of concrete for waterways according to the present invention and the repair method of the existing waterway using the member to repair the existing waterway,
It is an existing water channel that is formed in a gap between private houses, so that heavy machinery etc. cannot enter and repair work is extremely difficult, and it is for flowing normal household wastewater. Usually, there is almost no flow of water.Therefore, when it does not rain for a long time, it tends to become very unsanitary due to accumulation of trash and earth and sand, bad odor and weed breeding. The existing canal is easy to repair, can be easily repaired even at curved points, and even if there is only a small amount of flow, it can create a smooth flow, and even an existing canal with a slope There is an excellent effect that a flow can be created on the opposite slope side at the formation location.
以下本発明の実施例を図に基づいて説明する。 Embodiments of the present invention will be described below with reference to the drawings.
図1は本発明による水路用コンクリート製インバート部材及び該部材を使用して既設水路を補修した既設水路の補修工法の概略構成を説明する説明図であり、図に示す谷川1による既設水路は民家など既設構築物13の隙間をぬって形成され、重機などが入り込めない箇所に設けられており、このような既設水路が本発明の対象となる。
FIG. 1 is an explanatory diagram illustrating a schematic configuration of an invert member made of concrete for a water channel according to the present invention and a repair method of an existing water channel repaired using the member, and the existing water channel by Tanikawa 1 shown in the figure is a private house The existing
ここで、前記自然の谷川1に設けられた既設水路は、民家の隙間などをぬって形成される関係上、一般的には直線的に敷設することが比較的困難で、たとえば右方向や左方向に蛇行して形成されることが多々見受けられ、決して直線的水路として形成されているものではない。よってこのような谷川1に設けられた既設水路の補修においては、左右に蛇行していて、これに充分対応形成できる部材を使用して補修することが要請されるものとなる。 Here, the existing water channel provided in the natural Tanigawa 1 is generally relatively difficult to lay in a straight line because of being formed through a gap in a private house. It is often found that they are meandering in the direction and are not formed as straight channels. Therefore, in the repair of the existing water channel provided in the Tanikawa 1 as described above, it is required to repair by using a member that is meandering to the left and right and can be formed corresponding to this.
ここで、符号2は、水路用コンクリート製インバート部材を示す。
該水路用コンクリート製インバート部材2の構成につき説明すると、その外形は略直方体状をなして形成されており、その上面の幅方向略中央位置には、断面略U字状に凹む高速流水路部3が長手方向へ向かって連続的に設けられている。
Here, the code | symbol 2 shows the invert member made from concrete for waterways.
The configuration of the concrete invert member 2 for a water channel will be described. The outer shape of the invert member 2 is formed in a substantially rectangular parallelepiped shape, and a high-speed flowing water channel portion that is recessed in a substantially U-shaped cross section at a substantially central position in the width direction of the upper surface. 3 is provided continuously in the longitudinal direction.
そして、該高速流水路部3の両端から、前記水路用コンクリート製インバート部材2の上面幅方向両端に向っては、若干の上り勾配の角度で傾斜する集水傾斜面4,4が前記正面に形成されている。そして、前記幅方向略中央に設けられた高速流水路部3と集水傾斜面4,4とにより流水路部5が形成されるものとなる。
Then, from the both ends of the high-speed
次に、当該水路用コンクリート製インバート部材2の長手方向一方側端部には、略半円状に張り出す接続膨出部6が設けられている。また、その長手方向他端部には、前記説明した接続膨出部6に嵌り合う略半円状の接続凹み部7が設けられている。
Next, a
しかして、長手方向両端部に形成された接続膨出部6および接続凹み部7においては、水路用コンクリート製インバート部材2、2を接続したとき、その接続部において前記高速流水路部3とフレキシブルに連通するよう構成された接続用高速流水路部8が形成されるものとなる。
Thus, in the
その接続用高速流水路部8の形状は、図から理解されるように、水路用コンクリート製インバート部材2の長手方向両端部側に位置する高速流水路部3の幅方向両端から前記接続膨出部6および接続凹み部7の幅方向両端部側に向けて広幅に広げた状態、すなわち略扇状に広げた状態にして形成されている。
As can be understood from the figure, the shape of the high-speed flowing
そして、その深さは、連通する高速流水路部3の底部からの深さとほぼ同じ深さ(厚み)に形成され、もって接続膨出部6および接続凹み部7側の高速流水路部3は、幅方向略中央部に形成された直線状の高速流水路部3とスムーズに、段差なく繋げられ連通するものとなる。
And the depth is formed in the depth (thickness) substantially the same as the depth from the bottom part of the high-speed flowing
よって、一対の水路用コンクリート製インバート部材2の前記接続用膨出部6と前記接続用凹み部7とを嵌め合わせると、前述したように左右に向けてフレキシブルに、自由自在にカーブさせて水路用コンクリート製インバート部材2を繋げて敷設することが可能とされるのである(図1および図2参照)。
Therefore, when the connecting bulged
そして、このような民家など既設構築物13の隙間をぬって設けられた自然の谷川1などで構成された既設水路の補修に際しては、重機の搬入がきわめて困難であり、もって人力で運搬できる程度の重量からなる補修部材、すなわち人力で運搬できる程度の重量からなる水路用コンクリート製インバート部材2が好ましいとされるのである。
And when repairing an existing waterway composed of a natural Tanikawa 1 or the like provided through a gap in an existing
また、図に示す水路用コンクリート製インバート部材2はその両端部に接続膨出部6,接続凹み部7が設けられた部材であるが、たとえば直線部分が多く続く既設水路の補修においては、両端部に前記のような接続膨出部6や接続凹み部7が形成されていないタイプの水路用コンクリート製インバート部材2を使用することもできる。このような部材の方が直線部分の長く続く既設水路の補修に際してはコストが安価とすることができる。
In addition, the concrete invert member 2 for a water channel shown in the figure is a member provided with a
また、一方側にしか接続用膨出部6あるいは接続用凹み部7が形成されていないタイプの水路用コンクリート製インバート部材2を使用してもかまわないし、両端部に接続用膨出部6と接続用凹み部7とが形成された水路用コンクリート製インバート部材2を長さ方向中間位置から切断した長さの短いタイプ、あるいはそのような短いタイプの長さのものを型枠で形成し使用してもかまわないものである(図7および図8参照)。
Further, it is possible to use a concrete invert member 2 for a water channel in which the
次に、図3に本発明の第2実施例を示す。 Next, FIG. 3 shows a second embodiment of the present invention.
本実施例では、たとえば自然の谷川1による既設水路において、側壁9、9を水路用コンクリート製インバート部材2の両脇に接続して取り付け、いわゆる現場において組立ててコンクリート製側溝10を形成して補修した場合を示すものである。 In the present embodiment, for example, in an existing water channel formed by natural Tanigawa 1, the side walls 9 and 9 are attached to both sides of the concrete invert member 2 for water channel, and are assembled at a so-called site to form a concrete side groove 10 for repair. This shows the case.
しかして、当該側壁9の水路用コンクリート製インバート部材2への取り付け方法について本発明では何ら限定されないが、本実施例では水路用コンクリート製インバート部材2の幅方向両側の側端面にねじ穴11をあらかじめ設けておき、側壁9側に設けられた貫通穴12の外側から接続ねじ14を挿入し、水路用コンクリート製インバート部材2と両側壁9,9とを一体化することが考えられる。
Thus, the method for attaching the side wall 9 to the waterway concrete invert member 2 is not limited in the present invention. However, in this embodiment, the screw holes 11 are provided on the side end surfaces on both sides in the width direction of the waterway concrete invert member 2. It is conceived that the connecting
前記のように水路用コンクリート製インバート部材2の両脇に側壁9,9を取り付け、側溝10を形成することは、たとえば左右方向にカーブする箇所に敷設する場合においても施工することができる。この場合、カーブする外側の側壁9は比較的長い長さの側壁9を使用し、カーブする内側の側壁9には短い長さにカットした側壁9を使用するものとなる。 As described above, attaching the side walls 9 and 9 to the both sides of the concrete invert member 2 for waterway and forming the side groove 10 can be performed even in the case of laying in a place curved in the left-right direction, for example. In this case, the side wall 9 having a relatively long length is used for the curved outer side wall 9, and the side wall 9 cut to a short length is used for the curved inner side wall 9.
次に、図4ないし図6に本発明の第3実施例を示す。 Next, FIGS. 4 to 6 show a third embodiment of the present invention.
この実施例では、水路用コンクリート製インバート部材2の長手方向一端側の厚みを、長手方向他端側より厚く構成し、前記高速流水路部3を有する流水路部5に所定の勾配を有するよう形成したものである。
In this embodiment, the thickness of one end in the longitudinal direction of the concrete invert member 2 for the water channel is configured to be thicker than that of the other end in the longitudinal direction, and the flow channel portion 5 having the high-speed
このようなタイプの水路用コンクリート製インバート部材2は、主に、敷設箇所が勾配を有する斜面であり、しかも水を流す方向につき、前記敷設箇所である斜面の勾配とは逆の勾配で流れるよう構成しなければならない場合に使用されるものである。 Such a type of concrete invert member 2 for a waterway mainly has a slope where a laying portion has a slope, and it flows in a direction opposite to the slope of the slope that is the laying portion in the direction of flowing water. It is used when it has to be configured.
図6から理解されるように、敷設箇所は矢印Aに示すように、図6に向かって右側から左側へ下り勾配の傾斜面となっている。しかしながら、各種の事情により排水方向は矢印Bで示すように図6に向かって左側から右側へ流れるように構成しなければならない場合がある。よって、そのような場合には、本実施例の水路用コンクリート製インバート部材2を使用し、図6に示すように敷設構成することになる。図6から理解されるように、この水路用コンクリート製インバート部材2は、長手方向一端側と他端側との厚みを異ならせて形成され、もってそれぞれ形状が異なるものとなっているが、その厚みの差の比率、言い換えれば形状の差異は現場敷設箇所の斜面勾配によってそれぞれ異ならせるものとなる。 As can be understood from FIG. 6, the laying portion is an inclined surface having a downward slope from the right side to the left side in FIG. However, the drainage direction may have to be configured to flow from the left side to the right side in FIG. Therefore, in such a case, the waterway concrete invert member 2 of the present embodiment is used, and the construction is laid as shown in FIG. As can be understood from FIG. 6, the concrete invert member 2 for waterways is formed with different thicknesses at one end side and the other end side in the longitudinal direction, and each has a different shape. The ratio of the thickness difference, in other words, the difference in shape is made different depending on the slope gradient of the construction site.
従って、本発明では所定の勾配を有する敷設箇所に最適な逆流勾配の流水路部5を構成すべく、前述したように複数種類の勾配を有した水路用コンクリート製インバート部材2を製造し、前記の要請に迅速に対応しているのである。 Therefore, in the present invention, the invert member 2 made of concrete for a water channel having a plurality of types of gradients is manufactured as described above in order to configure the flow channel portion 5 having a reverse flow gradient optimum for a laying portion having a predetermined gradient, We are responding promptly to this request.
ここで、このような勾配の異なる水路用コンクリート製インバート部材2の製造は比較的簡単に行える。すなわち、型枠部材において長手方向両端側の厚みを調整する調整部材をたとえば調整ねじを用い、これを進退させることにより調節部材を取り付け調整し、これにより勾配の異なる水路用コンクリート製インバート部材2の製造を行うがごときである。 Here, the manufacture of the concrete invert member 2 for waterways having different gradients can be performed relatively easily. That is, the adjusting member for adjusting the thickness at both ends in the longitudinal direction in the formwork member is attached and adjusted by adjusting the adjusting member by moving the adjusting screw forward and backward, for example. It's a good time to do manufacturing.
なお、図9では、ほぼ水平面をなす敷設箇所においても、流水路部5に所定の勾配を有するよう構成したものであるが、この場合も複数種類の厚みの異なり、勾配の異なる水路用コンクリート製インバート部材2を製造し、迅速に現場で対応できるものとしている。 In FIG. 9, the flow channel portion 5 is configured to have a predetermined gradient even in a laying place that is substantially horizontal, but in this case as well, a plurality of types of different thicknesses and different gradient gradient product made of water channel concrete are used. The invert member 2 is manufactured and can be promptly handled on site.
ところで、第1実施例から第3実施例において、本発明の水路用コンクリート製インバート部材2には、高速流水路部3を有する流水路部5が形成されている。ここで、この高速流水路部3を形成する意義につき述べると、通常流量の少ない場合には、この高速流水路部3内において泥水を含んだ雨水などが流れることになる。
By the way, in the first to third embodiments, a flow channel portion 5 having a high-speed
そして、たとえ、泥水を含んだ雨水などの流量が少なくとも、前記高速流水路部3での水深を深くすることができる。と共に、水深を深くした結果、高速流水路部3の中でその流速をはやめることができ、これにより、水路用コンクリート製インバート部材2の上面全体にわたって汚泥などの土砂が堆積しにくいという効果をもたらすことになる。
For example, the flow rate of rainwater containing muddy water can at least deepen the water depth in the high-speed
さらにこの水路用コンクリート製インバート部材2の上面は幅方向両端部より略中央に向かって緩やかな下り傾斜面をなす集水傾斜面4,4として形成されているため、前記水路用コンクリート製インバート部材2上面に流れ込んだ雨水はこの下り傾斜面をなす集水傾斜面4,4上を通って略中央の高速流水路3に常に集水されることになる。
