The present invention is eco-friendly and ecological by using blocks that can protect fish resources, provide habitats for amphibians, and secure safe movement of fish and amphibians in river facilities such as freefalls and four-side dams in rivers. The present invention relates to a riverbed and a raft member that can be used to construct a beneficial raft structure, and a method of constructing a riverbed and raft to protect the bed using the same.

Typical river drop holes are concrete beams with a gravitational cross section. Such dropping holes have usually caused rebound problems such as adding water pollution and damaging the habitats of river fish in the process of placing underwater concrete. In addition, since the scour phenomenon occurs badly at the lower end of the drop hole after completion, it is notable to withstand the impact during the flood, especially damaged and repaired or rebuilt is also a major problem.

The revetment construction method using the revetment block, which has been attempted as part of the solution to the problems of the revetment facilities installed by the concrete pouring method, provides the spawning vegetation space of water plants such as spawning of river fish, securing a comfortable habitat, and willow reed plants.

In addition, the fishery, which is composed of the fishery block (4), creates an in-water fish passage for the fish that cannot splash on the water surface, providing free passage for fish that do not soar over the water, from fry to large fish. It will help to create the conditions that can be created.

In addition, all of the protrusions 21, 35, and 51 of the shoal block 2 submerged in the water among the shoal block 2 and the associate block 3 and the revetment block 5, like natural stones, act as an aeration tank to disturb the flow of water in the water. Therefore, it promotes the supply of oxygen to the water, which helps aquatic organisms and contributes to the natural purification of water quality.

In addition, the planting space 34 of the fishery block 3 and the planting groove 52 of the revetment blocks 5 and 5a create a good environment for planting or growing native plants or water plants, and particularly the revetment blocks 5 and 5a. Soil filled in the planting groove (52) and the assembly void of the) is connected to the foundation ground of the riverbank and banks to create an environment in which plants, insects, or microorganisms can grow, so it is excellent for realizing ecosystem conservation and river greening. Do.

And during the flood, the movement of soil due to the upstream side of the soil flows and causes the damage and disaster of the embankment due to the rise of the riverbed in the middle and downstream streams and the reduction of the communication surface. Reinforced riverbeds are particularly excellent in storing soils swept away from all sides of dams, and induces water to flow only through gaps in the bottom block (1), thus helping to prevent flooding of upstream and downstream rivers by soils.

In addition, all building blocks are subject to flexure and are pressed against the partial sinking chambers by their own weight, thus preventing further scouring.In addition, the block objects may be dislodged or lost in the scour caused by water flow at the tip and tail of the drop hole. This will have a structure that is not allowed.

As described above, the present invention provides a floor block having a unique structure and function, a reinforcement block, a fish block, an fish block, and a raft block, and reinforcement and rafting a river bed using these blocks. Due to the active pseudo-aeration caused by the protrusions of blocks, shoal blocks, fishery blocks, and raft blocks submerged in water, natural purification of water is promoted, and the improvement of water quality is expected. It is possible to restore and maintain after the restoration, and the soil filled in the pores of the revetment block resembling natural stone creates a good environment in which water plants such as reeds, pussy willows, and plants can grow to realize natural or artificial greening of rivers. It is a big help.

This river reinforcement and revetment construction method can be said to be a drop-off and four-sided dam reinforcement method that is highly environmentally friendly and has high expectations for ecosystem conservation.
