Environmentally-friendly safe weir comprising both water way and fishway

An environmentally-friendly safety weir with both a waterway and a fishway, comprising:

• a waterway pipe including:
• a horizontal waterway pipe horizontally provided on an embankment and connected to a first air supply pipe, the first air supply pipe provided for supplying air into the horizontal waterway pipe;
• a vertical waterway pipe extending from each of opposite ends of the horizontal waterway pipe downward along an outer side surface of the embankment;
• a bottom waterway pipe horizontally extending from an end of the vertical waterway pipe outward, the bottom waterway pipe being placed at a bottom of a body of water;
• and
• a water entering-and-exiting pipe extending from an end of the bottom waterway pipe upward so that water is drawn into or out of the waterway pipe through the water entering-and-exiting pipe;
• a fishway pipe provided on the waterway pipe and communicating with a second air supply pipe, the second air supply pipe provided for supplying air into the fishway pipe, the fishway pipe being configured such that a level of water in the fishway pipe is adjusted by increasing or reducing an amount of air in the fishway pipe;
• a control unit including:
• the first air supply pipe passing through the fishway pipe and connected to the waterway pipe, with a first intake-and-exhaust valve provided on the first air supply pipe, the first intake-and-exhaust valve controlling an increase or reduction in an amount of air in the waterway pipe;
• and
• the second air supply pipe communicating with the fishway pipe, with a second intake-and-exhaust valve provided on the second air supply pipe, the second intake-and-exhaust valve controlling an increase or reduction in an amount of air in the fishway pipe;
• and
• an internal underwater stairway provided in each of opposite sides of the fishway pipe, the internal underwater stairway comprising a plurality of stepped units vertically stacked on top of one another.
