Description

FENCE STRUCTURE FOR PREVENTING WAVE The present invention relates to the field of construction, and more specifically, to a railing structure for preventing wave overtopping. Globally, atmospheric temperature, sea surface temperature, rainfall intensity, wind speed, and sea level are increasing due to climate change such as global warming. The continuous rise in sea surface temperatures around the Korean Peninsula and changes in the rate of temperature increase by sea area may affect typhoon intensity and the number of typhoons influencing the region, and maximum wind speeds and maximum instantaneous wind speeds are expected to continuously increase. Coastal areas adjacent to the sea can suffer significant damage due to natural disasters that cause changes in sea level. Fluctuations in sea level along the coast cause flooding, and representative natural disasters caused by changes in sea level include storm surges and tsunamis. Factors influencing these sea level changes include mean sea level, astronomical tides, storm surges associated with extreme weather conditions, and high river discharges. As a result, coastal areas suffer damage from natural disasters such as storm surges every year. Although damage from tsunamis occurring on the Korean Peninsula is rare compared to storm surges, damage was reported on the east coast in 1983 and 1993 when large-scale earthquakes occurred in the waters off Japan. Information regarding past tsunami events indicates that the behavior and characteristics of tsunamis are significantly different from those of other coastal disasters. The main reason for these differences is the unique duration of action associated with tsunami phenomena. Waves generated by normal winds have a period of between 5 and 20 seconds, whereas tsunamis have a wave period of a few minutes to over an hour. In contrast, storm surges have cycles of several hours and can cause damage over a long period ranging from a few hours to several days. Storm surges caused by typhoons flood coastal areas for an extended period due to the repeated impact of waves and gusts over several hours. On the other hand, flooding caused by tsunamis generally occurs due to rapid water level changes over tens of minutes and large-scale currents lasting for several hours, and can cause damage within a relatively short period of time. The height of storm surges and tsunamis occurring in Korea is not large, within 1 to 2 meters, but the run-up height of waves rising after breaking against coastal barriers or breakwaters can exceed several meters. These run-ups account for the majority of wave overtopping, and wave overtopping caused by tsunamis triggers flooding in coastal areas, resulting in not only loss of life but also massive property damage. FIG. 1 and below illustrate embodiments of the present invention, FIG. 1 is a side view of a railing structure for preventing wave overtopping. FIG. 2 is a front view of a railing structure for preventing wave overtopping. Fig. 3 is a side view of the wave-overtopping prevention section. Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. As illustrated in FIG. 1 and below, the railing structure (100) for preventing wave overtopping according to the present invention is installed on a coastal structure (10) (coastal barrier, breakwater, etc.) and serves as a railing to prevent people from falling, and also performs the role of reducing wave overtopping when a storm surge or tsunami occurs. This is basically composed of a connecting part (110), a wave-breaking part (120), and a supporting part (130), and is preferably made of a metal material such as cast iron or aluminum. The connecting part (110) is a structure that connects to the edge of the coastal structure (10) and may have an L-shaped cross-sectional structure including a front connecting part (111) that connects to the front of the coastal structure (10) and an upper connecting part (112) that connects to the upper surface of the coastal structure (10). These are connected to the coastal structure (10) by means of an anchor connection structure, etc. The wave-breaking part (120) is formed with a lower end fixed to the connecting part (110) and a concave curved structure facing the sea, and it is preferable that it be formed as a curved plate structure made of steel. The support member (130) is coupled to the rear surface of the wave-breaking member (120) and the upper surface of the coupling member (110) so as to support the wave-breaking member (120). Specifically, this comprises a body part (131) in which the upper and rear ends are formed with an L-shaped cross-sectional structure and the lower end is connected to the upper surface of the upper surface connecting part (112); and a recessed part (132) formed in front of the body part (131) as a recessed structure corresponding to the rear surface of the wave-breaking part (120).
