Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は水路の構造に係るものである。[Detailed description of the invention] (Industrial application field) The present invention relates to the structure of a waterway.
（従来の技術）
従来の水路は水路トンネルを含めてコンクリートよシ構
成されていた。(Prior art) Conventional waterways, including waterway tunnels, were constructed of concrete.
（発明が解決しようとする問題点）
水路の流下能力は水路の粗度係数ｎに大きく支配される
ものであるが、従来のコンクリート水路は粗度係数が大
で流下能力に難点があシ、水路の断面が大きくなシ、不
経済である。(Problems to be Solved by the Invention) The flow capacity of a waterway is largely controlled by the roughness coefficient n of the waterway, but conventional concrete waterways have a large roughness coefficient and have difficulties in flow capacity. Since the cross section of the waterway is large, it is uneconomical.
（問題点を解決するための手段）
本発明はこのような問題点を解決するために提案された
もので、コンクリート構造の水路躯体内局面に、ポリ塩
化ビニル（ＰＶＣ） ｍを層着することによって、前記
の問題点を解決するものである。(Means for Solving the Problems) The present invention was proposed to solve these problems, and involves layering polyvinyl chloride (PVC) on the surface of the waterway frame of a concrete structure. This solves the above problems.
（作用）

水路に比して粗度係数が４０係〜５０％小さくなシ、水
路の流下能力が向上されるものである。(Function) Since the waterway according to the present invention has a PVC layer layered on the inner peripheral surface of the concrete structure of the waterway body, the waterway has a roughness coefficient of 40 to 50% smaller than that of conventional concrete waterways. This improves the flow capacity of the water.
（実施例） 以下本発明を図示の実施例について説明する。(Example) The present invention will be described below with reference to the illustrated embodiments.
第１図は本発明を馬蹄形断面の水路に適用した場合を示

いる。FIG. 1 shows the case where the present invention is applied to a waterway with a horseshoe-shaped cross section, in which the inner surface of a concrete structure waterway frame (1) is integrally lined with a polyvinyl chloride (PVC) layer (2).
第２図及び第３図は夫々本発明を円形断面の水路、並に

体に層着されている。Figures 2 and 3 show cases in which the present invention is applied to a waterway with a circular cross section, and a waterway with a rectangular cross section, respectively, in which 270 layers (2) are formed on the inner peripheral surface of a concrete structure waterway frame (1). It is layered in one piece.
前記各実施例においては、コンクリート構造の水路躯体

で、水路の粗度係数が従来のコンクリート水路に比して
大幅に小さく、水路の流下能力が向上し、水路断面を小
さくすることができ、また前記ＰＶＣ層（２）によって
水路の防蝕・性及び止水性が確保される。In each of the above embodiments, since the P'VC layer (2) is layered on the inner peripheral surface of the concrete-structured waterway frame (1), the roughness coefficient of the waterway is significantly greater than that of conventional concrete waterways. The PVC layer (2) ensures the corrosion resistance and water-stopping properties of the waterway.
