Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete block for a waterway and a waterway using the concrete block, and provides a preferable habitat or an evacuation place for fish and other aquatic organisms in a waterway constituted by a factory-produced precast concrete block. In particular, the present invention aims to provide a concrete block for a canal or a canal thereof capable of forming a canal capable of maintaining an appropriate survival condition for these aquatic organisms even under drought conditions.

[0002]

2. Description of the Related Art Since weeds and the like propagate in waterways of general rivers, and it requires a great deal of labor to manage and weed and clean them, precast concrete produced from such rivers has recently been manufactured. Is being widely used. That is, by using concrete blocks for the above-mentioned canals, even during the active breeding season of grasses such as in spring or summer, it is possible to prevent the crowding of the canals accurately and to reduce the labor required for managing the canals. It is being widely adopted in various fields because it can be brought to zero.

[0003]

Recently, the concrete block channel as described above has a merit that it is possible to form a waterside on which a weed or the like does not grow at a relatively low cost with a concrete block which is mass-produced in a factory. Since the formed waterways have a certain shape and are mass-produced, it is possible to secure a water basin, but there is no room other than this water basin, that is, when aquatic organisms such as fish try to inhabit. In addition, only constant flow velocity conditions can be obtained in all cross sections, and since the animals always move under conditions in which the entire surface is open, it is not possible to obtain rest or evacuation of aquatic organisms.

Therefore, in the paddy field area where the concrete block canal as described above is adopted, the distribution or reproduction state of fish and other aquatic organisms in the canal system is remarkably different. It has been reported in various fields that the block channel system is almost not required.
