Abstract
Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明は消波を目的とする透過式消波堤に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a permeable wave-dissipating dam for the purpose of dissipating waves.
一般に、直立型防波堤だと、これによって遮蔽された波
は、反射波となって防波堤全面海域を攪乱し、海底地盤
や隣接海岸を浸食する太きな原因になっている。Generally speaking, with a vertical breakwater, the waves that are blocked by the breakwater become reflected waves that disturb the entire sea area of the breakwater, and become a major cause of erosion of the seabed and adjacent coasts.
このため、最近では波の反射波を可能な限り小さくすべ

困難である等の欠点があり、未だ完壁なものは開発され
ていない。For this reason, recently, various wave-dissipating structures have been developed that should reduce reflected waves as much as possible. Furthermore, recently, permeable breakwaters that enable seawater exchange have been attracting attention, rather than being installed at a certain distance from the shore, but all of them have been difficult to construct due to problems such as on-site concrete IJ. There are drawbacks such as difficulty, and no perfect version has been developed yet.
この発明は、このような事情に鑑みて提案されたもので
、消波効果が極めて大きくかつ施工がきわめて簡単で経
済施工が可能な透過式消波堤を提供することを目的とす
る。The present invention was proposed in view of the above circumstances, and an object of the present invention is to provide a transparent wave-dissipating levee that has an extremely large wave-dissipating effect, is extremely simple to construct, and can be constructed economically.

することにより前記目的を達成するものである。This invention constructs a transparent wave breakwater by erecting wave breakwater caissons with a triangular cross section at regular intervals in a direction substantially perpendicular to the direction of wave travel, with one edge facing the wave travel direction. This achieves the above objective.

石等の中詰物３を充填することにより固定されている。The wave-dissipating caisson 2 is made of reinforced concrete or steel plate and is formed in the shape of a hollow column with an approximately equilateral triangular cross section. Wave-dissipating caissons 2 are built at regular intervals in the sea a little distance from the shore, perpendicular to the direction of wave propagation, and are filled with seawater or crushed stone. It is fixed by filling with a filling material 3 such as.

The wave-dissipating effect is enhanced by providing a plurality of wave-dissipating blades 5, 5 on the sides of the wave-dissipating blades. The length and number of wave-dissipating blades 5 shall be determined in consideration of design conditions such as wave conditions. For example, it may be installed only near the sea surface where water particle movement is large.
