OVERFLOW SUPPRESSION DEVICE OF EMBANKMENT, DAM AND THE LIKE (EMBANKMENT ETC.) PREVENTING NATURAL DISASTER BY FLOOD
To provide a simple, effective and economical countermeasure in a situation where, although a structure or a device capable of preventing an overflow does not exist in an embankment etc. and there is a hidden risk that an embankment etc. is collapsed by an overflow over a crown when filled with water and a flood occurs, a countermeasure is not clear and it is not known when and where a natural disaster by a flood occurs, and where a river overflow countermeasure progresses only so slowly possibly because so huge cost is needed for radical repair regarding flood countermeasure.SOLUTION: An overflow suppression device in which overflow suppression fences 4 capable of effectively suppressing overflow are continuously provided on a crown of an existing embankment etc. 2 by an economical construction work is used to prevent occurrence of a flood by an embankment collapse beforehand, as a device for an overflow prevention countermeasure to an embankment etc. for a case where extreme and abnormal water level rise occurs due to abnormal rain fall generated in a river basin and the like, by installing an overflow suppression device for restraining overflow on a crown 3 of an embankment etc. 2 of each river.SELECTED DRAWING: Figure 6
【課題】堤防等に越流を防止できる構造や装置が存在せず、満水時には天端に越水の越流によって堤防等が決壊し、洪水が発生する危険が潜んでいるにもかかわらず、対策さえ曖昧であり、洪水による自然災害の発生は何時何処で発生するか分からない現状である。しかしながら、洪水対策に係る抜本的改修には、途方もない経費を必要とするためか、河川の越水対策は遅々として進展しない現状がある。従って、簡単かつ効果的で経済性を有する対策を必要とする。【解決手段】各河川の堤防等２の天端３に、越流を阻止するための越流抑止装置を設置し、流域に発生した異常な降雨などで極端かつ異常な増水が発生した場合に備えて、堤防等に越流防止対策を施す装置として、既存の堤防等２に経済的な工事方法で、効果的に越流の抑止ができる越流抑止フェンス４を天端上に連設することによる越流抑止装置を用い、堤防の決壊による洪水の発生を未然に防止する。【選択図】図６
