Abstract

【課題】河川工事に使用されるコンクリートブロックにおいて、川床の土や砂
利を生かし魚等が生息できる構造としたコンクリートブロックを提供する。
【解決手段】コンクリートブロックの形状を矩形状の貫通孔を有する構造とし
、さらに積み重ねた際のズレ防止のための接続ピンを配置するピン用穴を複数箇所設けたことを特徴とする。前記貫通孔を設けることにより、川床の土や砂利が堆積し、水生植物や魚等の生息を確保することができる。

[PROBLEMS] To provide a concrete block having a structure in which fish and the like can inhabit by utilizing soil and gravel of a riverbed in a concrete block used for river construction.
The concrete block is characterized in that the shape of the concrete block has a rectangular through-hole, and a plurality of pin holes for arranging connection pins for preventing displacement when stacked are provided. By providing the through hole, soil and gravel on the riverbed accumulate, and it is possible to ensure the inhabiting of aquatic plants and fish.

Description

昨今、河川工事において、川床がコンクリートで固められ魚や、水草などが、生息できない状態になっている、
そこで、川床や、護岸に、このコンクリートブロックを設置することによって自然の川床が確保され、魚等が、生息しやすくなる、よって、この、魚と、川に やさしい、「コンクリートブロック」を提案する。Recently, in river construction, the riverbed is hardened with concrete, and fish, aquatic plants, etc. are in a state that can not live.
Therefore, by installing this concrete block on the riverbed and revetment, a natural riverbed will be secured and fish will be able to inhabit easily. .

３−１、現在、河川の、川床や、堤防の一部に、現場施工による、コンクリート作りのものがあり、その部分は、川床の土と、川水とが完全に遮断され、透水性が奪われ、水草も、生えない状態です。そこで、この「コンクリートブロック」を、設置し、石や砂利を、敷き詰めることによって、（自然に上流から土砂が流れてきて埋まることも可能）、透水性のある川床ができる。
３−２、又、このブロックの組み合わせを、階段状にしたりして、魚道の代りもできる、
３−３、現在、すでに在る、砂防えん堤などの下流に、時間をかけて、段積みすることによって、なだらかな勾配をつくり、魚が、溯上できるようになる。
３−４、工場生産品の為、現場施工より品質が安定し量産もできる。
コストも、天候に左右されることが無く安くできる。
又、工事期間も安定し、工程表も作りやすい。3-1. Currently, some riverbeds and embankments of the river are made of concrete by on-site construction. In this part, the riverbed soil and river water are completely blocked, and the permeability Stolen and aquatic plants do not grow. Therefore, by installing this “concrete block” and laying stones and gravel, it is possible to bury the riverbed with water permeability.
3-2 Also, this block combination can be made into a staircase to replace the fishway.
3-3. By taking time and stacking downstream of existing sabo dams, etc., a gentle gradient will be created and fish will be able to climb.
3-4. Because it is a factory-produced product, quality is more stable than on-site construction and mass production is possible.
Cost can be reduced without being affected by the weather.
In addition, the construction period is stable and it is easy to create a process chart.

最近河川工事において川床がコンクリートで固められ水草や水生昆虫などが生息できない状態になっているので考案のコンクリートブロックにすることによって自然の状態の川床が確保され水草や水生昆虫や魚などが生息できるようになる。Recently, the riverbed has been hardened with concrete in river construction, and aquatic plants, aquatic insects, etc. are not allowed to live. It becomes like this.

考案するコンクリートブロックを設置することによって現地施工するとき天候に左右されることもなく工事期間が安定し品質も良くなり工事費も比較的少なくて済む。By installing the concrete block to be devised, the construction period is stable and the quality is improved and the construction cost is relatively low without being influenced by the weather when performing the construction on site.
