Description

本発明は、山地において雨水の流れを制御したり、平地において事業用水を流す溝に設置されるＵ字溝パネルに関する。 The present invention relates to a U-shaped groove panel installed in a ditch for controlling the flow of rainwater in a mountainous area or for flowing commercial water in a flat area.

最近、山地において大量の雨が降って土砂崩れが多数発生したり、大洪水がしばしば起きたりして雨水のコントロール不良により大災害が発生している。また、道路脇の側溝の不設置により道路が使用できなくなったり、あるいは農業用の用水路の不設置等により作物の成長が十分期待できない場合があった。これらの場合に、山地の法面の水路、道路の側溝、農業用水路にコンクリートのＵ字溝を使用すると重いので、大掛かりな工事が必要となり、特に法面においては、その重量のため法面が崩れやすくなるため、軽くて搬送に便利で現場で簡易に組立てられるプラスチック製の折りたたみ式又は組立て式のＵ字溝パネルが考案されている。 Recently, a large amount of rain has fallen in the mountains, causing many landslides and frequent floods, causing major disasters due to poor control of rainwater. In addition, there were cases where the road could not be used due to the non-installation of gutters on the side of the road, or the growth of crops could not be expected sufficiently due to the non-installation of agricultural irrigation canals. In these cases, using concrete U-shaped grooves for mountain slope canals, road side ditches, and agricultural canals is heavy, so large-scale construction is required, and especially on slopes, the slope becomes heavy due to its weight. A plastic foldable or prefabricated U-groove panel has been devised that is light, convenient to transport, and easy to assemble in the field because it easily collapses.

実公昭６３−６２９８号Jitsukosho 63-6298 特開平９-３２８８０６号Japanese Patent Application Laid-Open No. 9-328806

特許文献１におけるＵ字状構造物及び特許文献２における樹脂製溝は、いずれも樹脂からなり、特許文献１は折りたたみ式で、特許文献２は組立て式である。特許文献１のものは、その長さ方向に複数本のＶ字状の屈曲溝５を有し、その屈曲溝５を折曲部として折り曲げてＵ字状に形成し、補強と曲げ剛性を高めるために構造物の巾方向に凹溝８を形成している。このＵ字状構造物は、組立ては容易であるが、単一板からなり強度的には不十分で、水の流れる部分（底面と側面）に凹凸が形成され、水のスムースな流れに対する障害がある。また、特許文献２のものは、底板３１、側板３５、下側側部１１及び上側側部２１等の複数部品を組立てて構成しなければならず、組立てに時間がかかるし、現場への搬送も煩わしい。 The U-shaped structure in Patent Document 1 and the resin groove in Patent Document 2 are both made of resin, Patent Document 1 is a foldable type, and Patent Document 2 is an assembly type. The one of Patent Document 1 has a plurality of V-shaped bending grooves 5 in the length direction thereof, and the bending grooves 5 are bent as bent portions to form a U-shape to enhance reinforcement and bending rigidity. Therefore, the concave groove 8 is formed in the width direction of the structure. Although this U-shaped structure is easy to assemble, it is composed of a single plate and is insufficient in strength, and unevenness is formed on the water flow part (bottom surface and side surface), which is an obstacle to the smooth flow of water. There is. Further, in Patent Document 2, a plurality of parts such as a bottom plate 31, a side plate 35, a lower side portion 11 and an upper side portion 21 must be assembled and configured, which takes time to assemble and is transported to the site. Is also annoying.

本発明の折りたたみ式Ｕ字溝パネルは、底板とその左右の２枚の側板からなり、これら底板と側板は二重壁から構成され、前記底板と側板の連結部には、側壁を折り上げたときに、互いに対向接触する斜壁が設けられ、この斜壁の一方には、突条体が形成され、斜壁の他方には、前記突条体に係合する凹条溝が形成されていることが好ましい。 The foldable U-shaped groove panel of the present invention is composed of a bottom plate and two side plates on the left and right sides thereof, and these bottom plates and side plates are composed of double walls, and a side wall is folded up at a connecting portion between the bottom plate and the side plates. Occasionally, sloping walls that face each other are provided, one of the sloping walls is formed with a ridge, and the other of the sloping walls is formed with a recessed groove that engages the ridge. It is preferable to have.

前記突条体と凹条溝は、水の流れる方向に互いに対向して伸びていることが好ましい。 It is preferable that the ridge and the groove extend so as to face each other in the direction of water flow.

また、前記側板の二重壁をなす内壁と外壁には、側板を折り上げたときに側板の上下方向に延びる補強溝が形成され、前記左右の側板の内壁に形成される補強溝は互いに対向位置に側板の上端に開放して形成され、この対向補強溝には、Ｕ字溝の水の流れを制御する堰板が着脱自在に取り付けられ得ることが好ましい。 Further, the inner wall and the outer wall forming the double wall of the side plates are formed with reinforcing grooves extending in the vertical direction of the side plates when the side plates are folded up, and the reinforcing grooves formed on the inner walls of the left and right side plates face each other. It is preferable that a weir plate that is formed at a position open to the upper end of the side plate and that controls the flow of water in the U-shaped groove can be detachably attached to the facing reinforcing groove.

また、前記底板の内壁は平坦であることが好ましい。 Further, it is preferable that the inner wall of the bottom plate is flat.

また、前記パネルはポリエチレンで形成されることが好ましい。 Further, the panel is preferably made of polyethylene.

本発明のＵ字溝パネルは、底板とその左右の側板からなり、二重壁で構成されているので、強度的にも十分であり、折りたたみ式なので、搬送時には平坦にして搬送できる。また、底板と側板の連結部の一方の斜壁には突条体を設け、これと対向する他方の斜壁には、突条体と係合する凹条溝を形成したので、連結部の強度も十分であるし、突条体と凹条溝とを結合させれば、側板は垂直に保持されて現場での設置作業が容易となる。 Since the U-shaped groove panel of the present invention is composed of a bottom plate and its left and right side plates and is composed of double walls, it has sufficient strength and is foldable, so that it can be flattened during transportation. Further, since a ridge is provided on one of the inclined walls of the connecting portion between the bottom plate and the side plate, and a concave groove that engages with the ridge is formed on the other inclined wall facing the ridge, the connecting portion can be connected. The strength is sufficient, and if the ridge and the concave groove are combined, the side plate is held vertically and the installation work at the site becomes easy.

また、前記側板の外壁及び内壁には、補強溝が形成されているので、パネルの強度が増すとともに内壁の補強溝は水の流量調節用の堰板の着脱自在支持溝を兼ねることが出来る。加えて、外壁に形成された補強溝は、側板に沿う土砂が崩れ左右側板に沿う土砂の流れにずれが生じたときに、土砂の流れの抵抗が凸状体に比較して小さいので、Ｕ字溝パネルの破損を防止することができる。更に、また、底板はフラットに形成されているので、パネルを平地に農業用として設置した場合でも、水の流れを妨害しないし、溝内に水が残留してしまうということがない。 Further, since the reinforcing grooves are formed on the outer wall and the inner wall of the side plate, the strength of the panel is increased, and the reinforcing groove on the inner wall can also serve as a detachable support groove for the weir plate for adjusting the flow rate of water. In addition, when the earth and sand along the side plates collapse and the flow of earth and sand along the left and right side plates shifts, the reinforcing groove formed on the outer wall has a smaller resistance to the flow of earth and sand than the convex body. It is possible to prevent damage to the groove panel. Furthermore, since the bottom plate is formed flat, even when the panel is installed on a flat ground for agriculture, it does not obstruct the flow of water and the water does not remain in the groove.

更に、また、前記パネルはポリエチレンで形成されているので、リユースでき環境負荷を小さくすることができる。 Furthermore, since the panel is made of polyethylene, it can be reused and the environmental load can be reduced.
