Description

本発明は、側溝と暗渠管とを接続する側溝暗渠管接続継手及びその接続構造に関する。 The present invention relates to a gutter underdrain pipe connecting joint for connecting a gutter and an underdrain pipe and a connection structure thereof.

図１に示すように、従来、道路に埋設される暗渠管１と道路に敷設される側溝２とを接続する場合、側溝２と暗渠管１とはグレーチング３付きの集水枡４を介して接続されていた（特許文献１、２参照）。すなわち、側溝２から暗渠管１に流れる雨水等は、一旦、集水枡４に溜まり、集水枡４を介して暗渠管１に流れ、逆に、暗渠管１から側溝２に流れる雨水等は、一旦、集水枡４に溜まり、集水枡４を介して側溝２に流れる。経年使用により集水枡４の底部に溜まった落ち葉、ゴミ、小石、泥等は、定期的にグレーチング３を外して除去される。 As shown in FIG. 1, when the underdrain pipe 1 buried in the road and the gutter 2 laid on the road are conventionally connected, the gutter 2 and the underdrain pipe 1 are connected to each other via a catchment basin 4 with a grating 3. It was connected (see Patent Documents 1 and 2). That is, the rainwater or the like flowing from the gutter 2 to the underdrain pipe 1 once collects in the catchment basin 4, flows to the underdrain pipe 1 through the catchment basin 4, and conversely, the rainwater or the like flowing from the underdrain pipe 1 to the side ditch 2 Once accumulated in the water collecting basin 4, it flows into the gutter 2 through the water collecting basin 4. Fallen leaves, dust, pebbles, mud, etc. accumulated at the bottom of the catchment basin 4 due to long-term use are periodically removed by removing the grating 3.

しかし、暗渠管１と側溝２とを金属製のグレーチング３付きの集水枡４を用いて接続した場合、グレーチング３を所謂鉄屑としてスクラップ会社に転売する目的で、グレーチング３の盗難が発生する。グレーチング３が盗難されると、道端に集水枡４の四角状の穴が空いてしまい、危険である。 However, when the underdrain pipe 1 and the gutter 2 are connected by using a catchment basin 4 with a metal grating 3, the grating 3 is stolen for the purpose of reselling the grating 3 as so-called iron scrap to a scrap company. .. If the grating 3 is stolen, a square hole in the catchment basin 4 will be opened on the roadside, which is dangerous.

また、集水枡４の底部に溜まった落ち葉、ゴミ、小石、泥等を定期的に除去するメンテナンスが煩雑であり、保全コストが必要となる。集水枡４の底部に溜まった水やゴミが腐って臭いの原因となる。臭いは、特に都市部では問題となる。 In addition, maintenance for periodically removing fallen leaves, dust, pebbles, mud, etc. accumulated at the bottom of the catchment basin 4 is complicated, and maintenance cost is required.

（暗渠管１）
図３（ａ）に暗渠管１を前方から見た斜視図を、図３（ｂ）に同じ暗渠管１を後方から見た斜視図を示す。この暗渠管１は、コンクリート製の四角筒からなり、一方の端面１１に管口１２を囲繞するように凸部１３が形成され、他方の端面１４に管口１５を囲繞するように凹部１６が形成されている。暗渠管１同士を直列に接続する際、一方の暗渠管１の凸部１３と他方の暗渠管１の凹部１６とが係合される。 (Underground pipe 1)
FIG. 3A shows a perspective view of the underdrain pipe 1 as viewed from the front, and FIG. 3B shows a perspective view of the same underdrain pipe 1 as viewed from the rear. The underdrain pipe 1 is made of a square cylinder made of concrete, and a convex portion 13 is formed on one end surface 11 so as to surround the pipe mouth 12, and a concave portion 16 is formed on the other end surface 14 so as to surround the pipe mouth 15. It is formed. When the underdrain pipes 1 are connected in series, the convex portion 13 of one underdrain pipe 1 and the concave portion 16 of the other underdrain pipe 1 are engaged with each other.

図３（ａ）、図３（ｂ）に示すように、暗渠管１の側面には、図示しないネジ棒及びナットが収容される収容部１７が凹設されている。収容部１７は、ナットを収容するため暗渠管１の側面に凹設された大収容部１７ａと、ネジ棒を収容するため大収容部１７ａから暗渠管１の端面に架けて凹設された小収容部１７ｂとから成る。大収容部１７ａは、その内部でナットを回転させることができるサイズであり、ネジ棒の直径に合わせられた小収容部１７ｂよりも大きい。 As shown in FIGS. 3A and 3B, an accommodating portion 17 for accommodating a screw rod and a nut (not shown) is recessed on the side surface of the underdrain pipe 1. The accommodating portion 17 is a large accommodating portion 17a recessed on the side surface of the underdrain pipe 1 for accommodating a nut, and a small accommodating portion 17a recessed from the large accommodating portion 17a to the end surface of the underdrain pipe 1 for accommodating a screw rod. It is composed of a housing portion 17b. The large accommodating portion 17a is sized so that the nut can be rotated inside the large accommodating portion 17a, and is larger than the small accommodating portion 17b adjusted to the diameter of the screw rod.

暗渠管１同士を直列に接続する際、双方の暗渠管１の端面に形成された凸部１３と凹部１６とを係合させると、双方の暗渠管１の小収容部１７ｂ同士が直線状に繋がるので、繋がった小収容部１７ｂにネジ棒を収容し、ネジ棒の両端を双方の暗渠管１の大収容部１７ａに位置させ、大収容部１７ａにおいてナットをネジ棒に締め込むことで、暗渠管１同士を締結する。暗渠管１の接続本数を適宜調節することで、接続された暗渠管１の全長を調節できる。なお、ネジ棒の代わりにボルトを用い、ボルトとナットで暗渠管１同士を締結してもよい。 When the underdrain pipes 1 are connected in series, when the convex portion 13 and the concave portion 16 formed on the end faces of both underdrain pipes 1 are engaged with each other, the small accommodating portions 17b of both underdrain pipes 1 become linear with each other. Since it is connected, the screw rod is accommodated in the connected small accommodating portion 17b, both ends of the screw rod are positioned in the large accommodating portion 17a of both underdrain pipes 1, and the nut is tightened to the screw rod in the large accommodating portion 17a.

図５（ｂ）、図２（ｂ）に示すように、継手本体７には、側溝２が接続される他方の側面７ｂに、側溝２の下面が載置される載置板２１が設けられていると共に、載置板２１に側溝２を上方から載せる際に側溝２の左右の側部が案内される一対の縦壁２２が側溝接続用開口９を挟むように左右に間隔を隔てて設けられている。これら載置板２１及び縦壁２２は、コンクリート製であり、継手本体７と共に一体的にコンクリート打設される。 (Mounting plate 21, vertical plate 22)
As shown in FIGS. 5B and 2B, the joint body 7 is provided with a mounting plate 21 on which the lower surface of the gutter 2 is mounted on the other side surface 7b to which the gutter 2 is connected. At the same time, a pair of vertical walls 22 that guide the left and right side portions of the gutter 2 when the gutter 2 is mounted on the mounting plate 21 from above are provided at intervals on the left and right so as to sandwich the gutter connection opening 9. Has been done. The mounting plate 21 and the vertical wall 22 are made of concrete, and are integrally cast with the joint body 7.

This enhances the centering property when the gutter 2 is landed on the mounting plate 21 from above. Further, as shown in FIGS. 5B and 6, the pair of vertical walls 22 are further formed in a tapered shape so that the distance becomes wider as the distance from the other side surface 7b of the joint body 7 increases. The centering property when connecting the gutter 2 to the joint body 7 from the longitudinal direction is improved.

（金網用凹部２３）
図５（ｂ）に示すように、継手本体７には、側溝２が接続される他方の側面７ｂに、上部が継手本体７の頂面６に開放された金網用凹部２３が、側溝接続用開口９を内包するように形成されている。図２（ａ）に示すように、継手本体７の他方の側面７ｂに側溝２が接続されたとき、図２（ｂ）、図２（ｃ）に示すように、側溝２の端面と金網用凹部２３との間にゴミ取用金網２４を継手本体７の頂面６の上方から差し入れるためのスリット２５が形成される。 (Recess for wire mesh 23)
As shown in FIG. 5B, the joint body 7 has a wire mesh recess 23 whose upper portion is open to the top surface 6 of the joint body 7 on the other side surface 7b to which the gutter 2 is connected. It is formed so as to include the opening 9. As shown in FIG. 2A, when the gutter 2 is connected to the other side surface 7b of the joint body 7, as shown in FIGS. 2B and 2C, the end face of the gutter 2 and the wire mesh are used. A slit 25 is formed between the recess 23 and the wire mesh 24 for removing dust from above the top surface 6 of the joint body 7.

図５（ｂ）を矢印IX方向から見た図９に示すように、継手本体７の他方の側面７ｂに側溝２が接続されたとき、側溝２の端面の肉厚部が継手本体７の金網用凹部２３を覆う状態となる。これにより、図２（ｂ）、図２（ｃ）に示すように、側溝２の端面と金網用凹部２３との間に、ゴミ取用金網２４を継手本体７の頂面６の上方から差し入れるためのスリット２５が形成される。 As shown in FIG. 9 when FIG. 5B is viewed from the direction of arrow IX, when the gutter 2 is connected to the other side surface 7b of the joint body 7, the thick portion of the end surface of the gutter 2 is the wire mesh of the joint body 7. It is in a state of covering the recess 23. As a result, as shown in FIGS. 2 (b) and 2 (c), the dust collecting wire mesh 24 is inserted between the end surface of the gutter 2 and the wire mesh recess 23 from above the top surface 6 of the joint body 7. A slit 25 for the purpose is formed.

図５（ｂ）、図８に示すように、継手本体７の頂面６には、ゴミ取用金網２４を指で引き上げるための指入凹部２６が形成されている。指入凹部２６は、継手本体７の金網用凹部２３の上部中央に配設されており、そこに指を差し入れることで、図２（ｂ）に示すスリット２５に差し入れられたゴミ取用金網２４の中央を保持してバランスよく引き上げることができる。 As shown in FIGS. 5B and 8, the top surface 6 of the joint body 7 is formed with a finger insertion recess 26 for pulling up the dust collecting wire mesh 24 with a finger.

（作用・効果）
本実施形態に係る側溝暗渠管接続継手５ｘ、５ｙ及びその接続構造によれば、次のような効果を発揮できる。 (Action / effect)
According to the gutter underdrain pipe connection joint 5x and 5y and the connection structure thereof according to the present embodiment, the following effects can be exhibited.

図１に示す集水枡４を利用して側溝２と暗渠管１とを接続する従来例とは異なり、図２（ａ）、図２（ｂ）、図２（ｃ）に示すように、集水枡４を使用することなく側溝２と暗渠管１とを継手本体７によって接続するので、集水枡４のグレーチング３が盗難される心配がなく、集水枡４に水やゴミ等が溜まって臭いの原因になることがない。集水枡４に溜まったゴミ、落ち葉、小石等を除去するメンテナンスが不要となり、保全コストを低減できる。 As shown in FIGS. 2 (a), 2 (b), and 2 (c), unlike the conventional example in which the gutter 2 and the underdrain pipe 1 are connected by using the catchment basin 4 shown in FIG. Since the gutter 2 and the underdrain pipe 1 are connected by the joint body 7 without using the catchment basin 4, there is no concern that the grating 3 of the catchment basin 4 will be stolen, and water, dust, etc. will be collected in the catchment basin 4. It does not accumulate and cause odor. Maintenance to remove dust, fallen leaves, pebbles, etc. accumulated in the catchment basin 4 becomes unnecessary, and maintenance cost can be reduced.

図２（ｃ）に示すように、継手本体７は、鉛直方向に沿った厚板状に形成され両側面に接続用の開口８、９が形成されたものなので、一辺８０ｃｍ程度の四角筒から成る図１に示す集水枡４よりコンパクトとなり、道路に埋設する際の掘削土砂量が少なくなり、道路への設置作業の負荷を軽減できる。コンクリート製の継手本体７のサイズが集水枡４よりもコンパクトとなるため、コンクリートの使用量が集水枡より少量で済み、集水枡４と比べて安価に製造できる。加えて、金属製のグレーチング３も不要なので、その分、集水枡４よりも安価となる。 As shown in FIG. 2 (c), the joint body 7 is formed in a plate shape along the vertical direction and has openings 8 and 9 for connection formed on both side surfaces, so that the joint body 7 is formed from a square cylinder having a side of about 80 cm. It is more compact than the catchment basin 4 shown in FIG. 1, the amount of excavated sediment when burying in the road is reduced, and the load of installation work on the road can be reduced. Since the size of the concrete joint body 7 is more compact than that of the catchment basin 4, the amount of concrete used is smaller than that of the catchment basin 4, and it can be manufactured at a lower cost than the catchment basin 4. In addition, since the metal grating 3 is not required, it is cheaper than the water collecting basin 4.

図２（ｃ）に示すように、暗渠管１の端面の凸部１３が側溝暗渠管接続継手５ｘの一方の側面７ａに形成された凹部１９に係合され、暗渠管１の端面の凹部１６が側溝暗渠管接続継手５ｙの一方の側面７ａに形成された凸部１８に係合されることにより、接続剛性が高まり、暗渠管１の上方の道路を自動車が通過して暗渠管１に荷重変動が加わることによって生じる、暗渠管１の暗渠管接続用開口８に対するズレを抑えられる。すなわち、暗渠管１の端面を継手５ｘ、５ｙの側面７ａに平面的に突き当てるのではなく、暗渠管１同士を接続するための凸部１３、凹部１６を利用して、暗渠管１の凸部１３、凹部１６を、継手５ｘ、５ｙの凹部１９、凸部１８に係合することで、振動などによる暗渠管１の暗渠管接続用開口８に対するズレを抑えられる。 As shown in FIG. 2 (c), the convex portion 13 of the end surface of the underdrain pipe 1 is engaged with the concave portion 19 formed on one side surface 7a of the side groove underdrain pipe connecting joint 5x, and the concave portion 16 of the end surface of the underdrain pipe 1 is engaged. Is engaged with the convex portion 18 formed on one side surface 7a of the side groove underdrain pipe connecting joint 5y, so that the connection rigidity is increased, and the automobile passes through the road above the underdrain pipe 1 and loads the underdrain pipe 1. It is possible to suppress the deviation of the underdrain pipe 1 with respect to the underdrain pipe connecting opening 8 caused by the addition of fluctuations. That is, instead of abutting the end surface of the underdrain pipe 1 against the side surface 7a of the joint 5x and 5y in a plane, the convex portion 13 and the concave portion 16 for connecting the underdrain pipes 1 are used to make the convex portion of the underdrain pipe 1 convex. By engaging the portions 13 and the concave portions 16 with the concave portions 19 and the convex portions 18 of the joints 5x and 5y, it is possible to suppress the displacement of the underdrain pipe 1 with respect to the underdrain pipe connecting opening 8 due to vibration or the like.

図３（ａ）に示す暗渠管１を図５（ａ）に示す側溝暗渠管接続継手５ｘに接続する際、暗渠管１の収容部１７に備えられたネジ棒（図示省略）が継手５ｘの一方の側面７ａに埋設された雌ネジ部材２０に螺合され、図３（ｂ）に示す暗渠管１を図４（ａ）に示す側溝暗渠管接続継手５ｙに接続する際、暗渠管１の収容部１７に備えられたネジ棒（図示省略）が継手５ｙの一方の側面７ａに埋設された雌ネジ部材２０に螺合される。このように、暗渠管１同士を連結するためのネジ棒を利用して暗渠管１と継手５ｘ、５ｙとを接続しているので、接続剛性が更に高まり、暗渠管１の上方の道路を自動車が通過して暗渠管１に荷重変動が加わることによって生じる、暗渠管１の暗渠管接続用開口１９に対するズレを一層抑えられる。 When the underdrain pipe 1 shown in FIG. 3A is connected to the side groove underdrain pipe connecting joint 5x shown in FIG. 5A, a screw rod (not shown) provided in the accommodating portion 17 of the underdrain pipe 1 is attached to the joint 5x. When the underdrain pipe 1 shown in FIG. 3B is screwed to the female screw member 20 embedded in one side surface 7a and connected to the side groove underdrain pipe connecting joint 5y shown in FIG. 4A, the underdrain pipe 1 is connected. A screw rod (not shown) provided in the accommodating portion 17 is screwed into the female screw member 20 embedded in one side surface 7a of the joint 5y. In this way, since the underdrain pipe 1 and the joints 5x and 5y are connected by using the screw rod for connecting the underdrain pipe 1 to each other, the connection rigidity is further increased, and the road above the underdrain pipe 1 is driven by an automobile. The deviation of the underdrain pipe 1 with respect to the underdrain pipe connecting opening 19 caused by the load fluctuation applied to the underdrain pipe 1 can be further suppressed.

図２（ｃ）に示すように、側溝暗渠管接続継手５ｘの他方の側面７ｂに、側溝２の下面が載置される載置板２１を設け、側溝暗渠管接続継手５ｙの他方の側面７ｂに、側溝２の下面が載置される載置板２１を設けたので、経年経過時の地盤沈下による側溝２の側溝接続用開口９に対する上下ズレを防止できる。また、図２（ｂ）、図４（ｂ）、図５（ｂ）に示すように、継手５ｘ、５ｙの他方の側面７ｂに、載置板２１に側溝２を上方から載せる際に側溝２の左右の側部が案内される一対の縦壁２２を設けたので、経年経過時の側溝２の側溝接続用開口９に対する左右ズレを防止できる。 As shown in FIG. 2 (c), a mounting plate 21 on which the lower surface of the gutter 2 is placed is provided on the other side surface 7b of the gutter underdrain pipe connecting joint 5x, and the other side surface 7b of the gutter underdrain pipe connecting joint 5y is provided. Since the mounting plate 21 on which the lower surface of the gutter 2 is mounted is provided, it is possible to prevent the gutter 2 from shifting up and down with respect to the gutter connecting opening 9 due to the ground subsidence over time. Further, as shown in FIGS. 2 (b), 4 (b), and 5 (b), the gutter 2 is placed on the other side surface 7b of the joint 5x and 5y when the gutter 2 is mounted on the mounting plate 21 from above. Since a pair of vertical walls 22 are provided to guide the left and right side portions of the gutter, it is possible to prevent the gutter 2 from shifting to the left and right with respect to the gutter connecting opening 9 over time.

図４（ｂ）、図５（ｂ）、図９に示すように、一対の縦壁２２が下部から上部に向かって間隔が広くなるようにスロープ状に形成されているので、側溝２を上方から載置板２１に載せる際、センタリング性が高まり、側溝２を側溝接続用開口９に容易に位置合わせでき、施工の作業性が向上する。また、一対の縦壁２２が下部から上部に向かって間隔が広くなるようにスロープ状に形成されているので、製造時に型枠に生コンクリートを流し込んで打設した後、型枠から抜き易い。 As shown in FIGS. 4 (b), 5 (b), and 9, the pair of vertical walls 22 are formed in a slope shape so as to widen the distance from the lower part to the upper part, so that the gutter 2 is upward. When the gutter is mounted on the mounting plate 21, the centering property is improved, the gutter 2 can be easily aligned with the gutter connecting opening 9, and the workability of construction is improved. Further, since the pair of vertical walls 22 are formed in a slope shape so as to widen the space from the lower part to the upper part, it is easy to remove the ready-mixed concrete from the formwork after pouring the ready-mixed concrete into the formwork at the time of manufacturing.

図４（ｂ）、図５（ｂ）、図６に示すように、一対の縦壁２２が継手本体７の他方の側面７ｂから離間するにつれて間隔が広くなるようにテーパー状に形成されているので、側溝２を継手本体７の他方の側面７ｂに近づける際、センタリング性が高まり、側溝２を側溝接続用開口９に容易に位置合わせでき、施工の作業性が向上する。また、一対の縦壁２２が継手本体７の他方の側面７ｂから離間するにつれて間隔が広くなるようにテーパー状に形成されているので、製造時に型枠に生コンクリートを流し込んで打設した後、型枠から抜き易い。 As shown in FIGS. 4 (b), 5 (b), and 6, the pair of vertical walls 22 are formed in a tapered shape so as to increase the distance from the other side surface 7b of the joint body 7. Therefore, when the gutter 2 is brought closer to the other side surface 7b of the joint body 7, the centering property is enhanced, the gutter 2 can be easily aligned with the gutter connecting opening 9, and the workability of construction is improved. Further, since the pair of vertical walls 22 are formed in a tapered shape so that the distance becomes wider as the distance from the other side surface 7b of the joint body 7 increases, ready-mixed concrete is poured into the formwork at the time of manufacturing and then placed. Easy to remove from the formwork.

図２（ｂ）、図２（ｃ）に示すように、継手本体７と側溝２との間に形成されたスリット２５にゴミ取用金網２４を上方から差し入れることで、側溝２を雨水と共に流れる落ち葉、ゴミ、小石等をゴミ取用金網２４によって捕集でき、落ち葉、ゴミ、小石等が暗渠管に流れ込む事態を回避できる。 As shown in FIGS. 2 (b) and 2 (c), by inserting the dust collecting wire mesh 24 into the slit 25 formed between the joint body 7 and the side groove 2 from above, the side groove 2 is inserted together with rainwater. The flowing fallen leaves, dust, pebbles, etc. can be collected by the dust collecting wire mesh 24, and the situation where the fallen leaves, dust, pebbles, etc. flow into the gutter can be avoided.

図９に示すように、厚板状の継手本体７の一方の側面７ａに形成された金網用凹部２３と、その側面７ａに接続される側溝２の端面の肉厚部とを協働させてスリット２５を形成しているので、例えば、図５（ｂ）に示す継手本体７の頂面６の板厚方向の中央にゴミ取用金網２４用のスリットを鉛直方向にコンクリート打設により形成する場合に必要となる中子が不要となり、継手本体７を低コストに製造できる。 As shown in FIG. 9, the wire mesh recess 23 formed on one side surface 7a of the plate-shaped joint body 7 and the thick portion of the end surface of the side groove 2 connected to the side surface 7a are made to cooperate with each other. Since the slit 25 is formed, for example, a slit for the dust collecting wire mesh 24 is formed in the center of the top surface 6 of the joint body 7 shown in FIG. 5B in the plate thickness direction by placing concrete in the vertical direction. The core, which is required in some cases, is no longer required, and the joint body 7 can be manufactured at low cost.

なお、ゴミ取用金網２４に捕集された落ち葉、ゴミ、小石等は、側溝暗渠管接続継手５ｘ、５ｙに隣接する側溝２の蓋板２ａを取り外し、上方から除去できる。また、指入凹部２６に指を差し入れてゴミ取用金網２４を引き上げることで、側溝２から暗渠管１の内部を点検でき、内部に侵入した落ち葉、ゴミ、小石等を掻き出すこともできる。 The fallen leaves, dust, pebbles, etc. collected in the dust collecting wire mesh 24 can be removed from above by removing the lid plate 2a of the gutter 2 adjacent to the gutter underdrain pipe connecting joint 5x and 5y. Further, by inserting a finger into the finger insertion recess 26 and pulling up the dust collecting wire mesh 24, the inside of the underdrain pipe 1 can be inspected from the gutter 2, and the fallen leaves, dust, pebbles and the like that have invaded the inside can be scraped out.
