Abstract

[Problem] To provide an oval-shaped tube that allows for easy connection and separation, without creating steps within the flow path holes when connecting (connecting) the oval-shaped tubes, and without the residual phenomenon of sediment in the flow path holes, allowing fluid and sediment to flow easily. [Solution] In this invention, a main body made of an oval tube is integrally molded with connecting parts made of circular tubes at both ends, and a number of oval tubes are connected via the connecting parts made of circular tubes, so that no step is created between the flow path hole of one oval tube and the flow path hole of another oval tube connected thereto, and so that fluid and sediment can flow smoothly.

Description

This invention relates to an oval-shaped tube that is easy to connect and separate, and more particularly to an oval-shaped tube in which a connecting portion made of a circular tube is integrally molded at both ends of the main body made of an oval-shaped tube, thereby enabling easy connection of multiple oval-shaped tubes without creating steps within the flow path hole using already existing circular tube connecting devices. Typically, water and sewage pipes are made primarily of synthetic resin and are constructed as circular pipes with a circular cross-section (a cylindrical pipe structure). As mentioned above, while the curved lower end of these circular pipes allows for flexible fluid flow, the slow speed of the fluid makes them unsuitable for quickly discharging fluids like sewage. Furthermore, they have the problem of retaining sediment and inducing foul odors. Furthermore, because the pressure resistance of the circular tube was weak, it would crack or break after a certain period of time, leading to a problem where fluid would leak out. To resolve the problems with the circular tubes mentioned above, oval-shaped tubes are used, which are formed with a wider upper end and a narrower lower end, resulting in an overall oval cross-section. The aforementioned egg-shaped pipe has the advantage of increasing the flow velocity of the fluid (sewage) passing through it, allowing for rapid movement (discharge), and also being able to withstand the load pressure from above. However, because the egg-shaped pipes are simply connected using egg-shaped connecting pipes that have the same shape and pattern as the egg-shaped pipes, the expertise required for connecting the egg-shaped pipes is lacking, and efficient connection is not achieved. As a result, not only does water leakage occur due to a decrease in watertightness and airtightness at the connection points, but the connection points are also not maintained stably. Furthermore, the aforementioned oval-shaped tubes are not only difficult to connect and install correctly due to their oval cross-sectional structure, but they also tend to warp or lie flat when their length increases. Therefore, when many of these tubes are connected, they become unable to efficiently move fluids, resulting in reduced transport capacity and decreased strength of the tubes. In particular, while separate connecting devices have been developed and are used for oval-shaped tubes due to the characteristics of their cross-sectional shape, the oval-shaped tube connecting devices have a problem in that their range of use is limited to oval-shaped tubes, resulting in reduced efficiency. Furthermore, the cross-sectional structure of egg-shaped pipes is not standardized; each manufacturer has a different egg-shaped cross-sectional structure. Because the egg-shaped pipe connection device used varies depending on the type of egg-shaped pipe being installed, installation costs increase, and on-site work efficiency decreases. Due to these problems, egg-shaped pipes are not commonly used in actual construction sites. Various research and development efforts have been made to resolve the problems associated with connecting (connecting) the egg-shaped tubes described above, but most of them concern connecting devices for the egg-shaped tubes, and there are no configurations for changing the shape of the egg-shaped tubes themselves, as in the present invention.
