[Problems to be Solved by the Invention] In recent river construction,
It is good not only to prevent scouring and sediment accumulation, but also to maintain the natural environment of rivers, or to restore the natural environment to create living areas and enrich the ecosystem. It is hoped that a clear river environment will be formed.

[0004] Rivers are inhabited by fish and shellfish that prefer shallow water, small animals, ephemera, winged gerbils, kawana, etc., and often gather in shallow water when it becomes dark at night. In rivers, fish are going up and down for spawning.

However, when a large number of conventional protection beds are laid, a shallow river where fish and other living creatures gather and a fishway where fish move up and down are not formed, so that the river environment is improved while maintaining the ecosystem. It was difficult to form.

Further, when a large number of conventional guard floor blocks are laid, children may fall into the vertical hole, and thus there is a safety problem in making the above guard floor block a place to enjoy the nature of the river. .

[0007] In the sea where there is a large tidal difference and there is a lagoon,
When the tide is high, the mud floating from the lagoon runs up the river,
Between high tide and low tide, the stagnation of tides causes sedimentation and sedimentation, and when the tide ebbs, lagging mud is deposited, so the sedimentation proceeds.

Therefore, the present invention has a function of preventing scouring or preventing sedimentation and sedimentation of earth and sand, storing water, purifying, etc. by laying a large number of them and forming shallow waters and murmuring to enrich the ecosystem and enhance the natural environment. The purpose of the present invention is to provide a bed block that can improve the quality.
