There are 1) caused by ocean currents, 1) tidal currents, 1) wave currents, and 1) density currents, etc. However, the flow speed of seawater on the seabed is extremely slow compared to that on the sea surface, and the movement of unnecessary floating materials that accumulate on the seafloor, Purification is extremely difficult, and the abnormal growth of plankton caused by this is one of the causes of the Red 1 Tide, causing not only difficulties in aquaculture but also widespread environmental degradation, such as the annihilation of tuna. In addition, the current situation is that the accumulation of organic and inorganic substances on lakebeds and riverbeds is causing deterioration of the water environment.

る。0 Functions and Examples The flowing water upwelling block of the present invention having the above structure can be installed, for example, in an area where the purification of the seabed is desired, by lifting it with a crane or the like through the support hole 6 and lowering it sequentially from the sea surface to the seabed. However, at this time, the through hole 4 provided in the fixed base 3 serves to reduce the resistance of the seawater, making it possible to install it at a desired location. In addition, since unnecessary suspended matter is deposited on the bottom sediment of the seabed area where the block is desired to be installed, when installing the block, the conical or cylindrical tip 7 protruding from the fixed base 3 should be placed on the bottom sediment. The fixed base 3 prevents the block from moving when it hits the soil, and also prevents it from being buried in soft ground and preventing it from falling over. Its size depends on the degree of softness of the ground and the flow rate of seawater on the seabed. The size can be set to an arbitrary size.
いま、該ブロックの設置時の作用としては前記した海水

、底質土上に存在する浮遊物は海水と共に上方に湧昇す
るものである。Now, the function when installing this block is that when the seawater moves as described above, the seawater that flows oppositely between two adjacent wall plates 1-1 to 1-4 flows into the center part 2. Therefore, since the distance between the wall plates is narrow, seawater has the effect of being pushed upwards above the block. At this time, suspended matter existing on the bottom soil rises upward together with seawater.

For example, in tuna farming, even if leftover food from feeding is deposited on the seabed, when the seawater moves, it upwells together with the seawater at the location where the block is installed, and it is removed from the seabed. In addition to natural purification, the uneaten food that rises up becomes food for a variety of fish in the natural world, and as a result, it creates a fish-attracting effect that attracts a large number of fish, and the installation of a large number of blocks can also be expected to create a fish reef effect. The flow between the installed blocks causes a flash phenomenon, which contributes to the disturbance and upwelling of floating objects on the sea floor.
