Description
本発明は、既存及び新設ダム、防波堤、防潮堤、又は堤防等の堤防設備の頂上部に上部構造物を設置することにより、堤高を上げることができる、ダムの天端高を高くするための上部構造物（Upper structure to increase the height of dam/bank levee crown）に関するものである。 The present invention can raise the height of the dam by increasing the height of the dam by installing an upper structure at the top of the existing and new dams, breakwaters, seawalls, or other levee facilities. Is related to the upper structure to increase the height of dam / bank levee crown.
一般的に、フィルダム（ｆｉｌｌ ｄａｍ）とは、土石材料をなだらかな勾配で築造したダム堤体の自重で貯水による水圧を支える形式のダムである。基礎地盤が軟弱な場合にも築造することができ、ダム付近の各種材料に合わせて自由に設計することができるため、他の形式のダムの施工が困難である地域においても経済的に開発することができる。しかし、越流への抵抗力が弱いとの欠点があり、洪水処理施設に巨額の費用がかかる場合が多い。 In general, a fill dam is a type of dam that supports the water pressure due to stored water by its own weight of a dam body constructed of a debris material with a gentle slope. It can be built even when the foundation ground is soft and can be designed freely according to various materials in the vicinity of the dam, so it can be developed economically even in areas where construction of other types of dams is difficult be able to. However, there is a drawback that the resistance to overflow is weak, and flood treatment facilities are often expensive.
特に、最近、世界的な異常気象により洪水が頻繁に発生しており、洪水による水災害の規模がますます拡大しているのが現実である。そのため、可能最大降水量（Ｐ．Ｍ．Ｐ）が既存ダムの設計当時よりも増加され、可能最大洪水量の流入時のダム安定性を確保しなければならなくなっている。 In particular, recently, floods have frequently occurred due to global abnormal weather, and it is a reality that the scale of water disasters caused by floods is increasing. Therefore, the maximum possible precipitation (PMP) has been increased from the time of the design of the existing dam, and it is necessary to ensure the dam stability at the inflow of the maximum possible flood.
本発明は、洪水による気象災害とかんばつの被害を同時に解決するために、既存及び新設ダム（、堤防、防波堤、又は防潮堤）の構造的及び/又は水理的な安定性をさらに確保し、経済的な効果を甚大に引き上げられる、ダムの天端高を高くするためのコンクリート構造物に関するものである。 The present invention further ensures the structural and / or hydraulic stability of existing and new dams (and dikes, breakwaters, or seawalls) in order to simultaneously solve weather disasters and drought damage due to floods. This is related to a concrete structure for increasing the height of the top of the dam, which can greatly increase the economic effect.
本発明の上部構造物は、従来より増加した可能最大洪水量に対処できるように、ダムの天端高を高くし、越流を防止するように構成されている。
また、本発明は、前記ダムの天端高を高くするためのコンクリート上部構造物を手段として堤高を上げ、既存ダムの貯水容量や河川の通水断面を著しく増加させることができる。
The superstructure of the present invention is configured to increase the top height of the dam and prevent overflow so as to cope with the maximum possible flood volume that has been increased.
In addition, the present invention can raise the bank height using the concrete superstructure for increasing the top height of the dam as a means, and can significantly increase the water storage capacity of the existing dam and the cross section of the river.
本発明の目的は、前記可能最大降水量の増加による洪水とかんばつに対処するために、既存ダムや堤防の頂上部にクラウン（ｃｒｏｗｎ）型のコンクリート構造物を追加設置することにある。 An object of the present invention is to additionally install a crown-type concrete structure at the top of an existing dam or embankment in order to cope with floods and droughts due to an increase in the maximum possible precipitation.
本発明は、前記目的を達成するために、コンクリート製の上部構造物はその中心から下方へ伸びた鋼材シートパイル（ｓｔｅｅｌ ｓｈｅｅｔ ｐｉｌｅ）を有する。この鋼材シートパイルは漏水を防止し、水圧による貫孔作用が生じないようにすることができる。
本発明の上部構造物はボックス（ｂｏｘ）状の空間部を形成し、その内部を土砂及び／又は石材などで埋め、ダムの天端（堤防の頂上部）の路面を形成するようにする。
In order to achieve the above object, according to the present invention, the concrete superstructure has a steel sheet pile extending downward from the center thereof. This steel sheet pile can prevent water leakage and prevent a through-hole effect due to water pressure.
The superstructure of the present invention forms a box-like space, and the interior is filled with earth and sand and / or stones to form the road surface at the top of the dam (top of the levee).
以上、本発明の説明によれば、本発明は水の貯蔵、波高又は越流防止のための設備であるダム、堤防、防潮堤、防波堤、堤防設備を新築しなくてもかなり安いコストで簡単な構造物を天端に追加設置することにより、ダムの天端高を高くすることができる。
特に、本発明は、天端に形成された上部構造物により堤高が高くなり、貯水容量を著しく増加させ、洪水又はかんばつに効率的に対処することができるようになる。
また、本発明による上部構造物はコンクリートからなり、天端における漏水量や貫孔作用及び波高、越流を防止し、ダムや堤などの堤防設備の構造的な安定性を図る。
As described above, according to the description of the present invention, the present invention can be easily implemented at a considerably low cost without newly constructing a dam, a dike, a tide embankment, a breakwater, or a dike facility for water storage, wave height or overflow prevention. The height of the top of the dam can be increased by installing a simple structure at the top.
In particular, according to the present invention, the height of the embankment is increased by the superstructure formed at the top, the water storage capacity is significantly increased, and floods or droughts can be effectively dealt with.
In addition, the superstructure according to the present invention is made of concrete and prevents the amount of water leakage, through-hole action, wave height, and overflow from the top, and aims at structural stability of dams and dykes.
