EROSION PREVENTIVE STRUCTURE FOR SANDY BEACH
PROBLEM TO BE SOLVED: To provide an erosion preventive structure for a sandy beach that prevents erosion of the sandy beach and captures sand at the same time, without using external motive power.SOLUTION: An erosion preventive structure for a sandy beach of the present invention is the erosion preventive structure for a sandy beach that prevents erosion of a sandy beach and captures sand at the same time, and includes: a catch pit extending almost in parallel with a shore line of the sandy beach and being defined by a non-permeable partitioning wall; a collection unit installed at a bottom part of the catch pit and having an intake port near a bottom part of the collection unit; a permeable capturing body charged in the catch pit; and a drainage channel extending toward offshore from a lower part of the collection unit. Sand contained in flowing water is captured with the capturing body while the flowing water is naturally drained through the collection unit and the drainage channel, after passing through the capturing body.SELECTED DRAWING: Figure 1
【課題】外部動力を用いることなく、砂浜の浸食防止と、砂の捕捉を両立できる、砂浜浸食防止構造体を提供すること。【解決手段】本発明の砂浜浸食防止構造体は、砂浜の浸食を防止しつつ、砂を捕捉する、砂浜浸食防止構造体であって、砂浜の汀線に略平行して延設し、難透性の仕切り壁で画成した、集水溝と、集水溝の底部に設置され、底付近に取水口を有する、集水ユニットと、集水溝に充填した、透水性を有する、捕捉体と、集水ユニットの下部から沖合へ向けて延びる、排水路と、を有し、捕捉体を透過させた流水を集水ユニット及び排水路を通じて自然排水しつつ、流水に含まれる砂を捕捉体で捕捉することを特徴とする。【選択図】図１
