Description

Prefabricated structure for implementing an undersea topography within the water tank The present invention relates to a prefabricated structure, and more specifically, to a prefabricated structure that implements a seabed topography within a tank, which enables hydraulic experiments to be conducted under conditions similar to reality by implementing seabed topography of various lengths, widths, and angles within the tank, thereby increasing the reliability of the performance evaluation of marine disaster prevention structures through hydraulic experiments, and also allows for easy installation and dismantling by being prefabricated. If the performance of marine disaster prevention structures deteriorates, it is difficult to expect significant disaster prevention effects. Therefore, it is essential for marine disaster prevention structures to undergo performance evaluation before being applied to the field. Meanwhile, generally, such performance evaluation can be carried out through hydraulic model experiments under various conditions using a water tank. However, while actual seabed topography includes various slopes and variability, the bottom of the tank used for hydraulic experiments is flat, so there is a limitation in that the hydraulic experiment conditions in the tank do not sufficiently reflect the actual environment. To resolve this problem, when conducting hydraulic experiments, a 'slanted structure' as disclosed in Korean Registered Patent No. 10-1304671, etc., is installed inside the tank. Therefore, since the seabed slope can be simulated within the tank by the inclined structure, hydraulic experiment conditions can be made more similar to reality, thereby increasing the reliability of the hydraulic experiment results. However, conventional inclined structures installed inside water tanks were complex in structure, which caused problems with the inconvenience of manufacturing and maintenance. To address these issues, there has been an increasing use of inclined concrete structures within water tanks; however, these structures not only require significant cost and time to manufacture, but also suffer from limited utility. Specifically, since they must be produced with fixed lengths, widths, and angles—meaning they cannot be modified—they had to be fabricated separately whenever different lengths, widths, or angles were required for specific experimental conditions. In addition, concrete sloped structures are difficult to dismantle due to the characteristics of the material, which presented a problem in that the dismantling work required significant costs and time. For the reasons mentioned above, attempts are being made in this field to develop inclined structures that allow hydraulic experiments to be conducted under conditions similar to reality by implementing seabed topography of various lengths, widths, and angles within a tank, thereby increasing the reliability of performance evaluations of marine disaster prevention structures through hydraulic experiments, and also facilitate installation and dismantling by being prefabricated; however, satisfactory results have not been obtained to date.
