Problems solved by technology

[0003] However, the deeper the water depth, the longer the falling time of the stone or block, and the longer time it is affected by the flow of seawater such as tidal currents in addition to the scattering during the falling process, and the scattered area (scattering range) becomes larger. Therefore, In deep waters, the bottom area of ​​artificial seamounts will expand, and the total volume will also increase

Embodiment Construction

[0022] Hereinafter, the artificial seamount of the present invention will be described in detail with reference to the accompanying drawings. figure 1 The conical structure 1 constituting the artificial seamount shown in A to 1C is constructed by throwing a large number of blocks from the sea surface and accumulating a single elliptical cone on the seabed. In order to further improve the upwelling effect of seawater and the effect of fish reefs, the following approximate cone is constructed: the projected area S1 of the approximate cone in the direction of seawater flow along ocean currents or tidal currents (direction roughly parallel to the flow) It is larger than the projected area S2 in the direction blocking the seawater flow (direction substantially perpendicular to the flow) (S1>S2). Such as figure 1 As shown in A, the planar shape of the artificial seamount 1 is constructed as an ellipse having a short axis in the direction along the flow of seawater (hereinafter refe...

Abstract

The invention relates to a construction method of an artificial seamount range and the artificial seamount range. Multiple block groups are manufactured by virtue of annularly connecting multiple blocks (10) via ropes / wires penetrating through via holes. The total length of each rope / wire is set to enable the length of the rope / wire between every two blocks to be 0.1 to 4.0 times of the length of one edge of each block averagely. The multiple block groups connected via the ropes / wires with the set lengths to fall from the sea surface down to the sea floor, thereby constructing at least a part of the artificial seamount range (21) which is roughly conical. In the artificial seamount range formed by the multiple conical structures which are linearly arranged in an overlapped manner in the direction blocking the flow of seawater, the projection area S1 in the direction along the flow of the seawater is set to be 0.8 to 4.0 times of the projection area S2 in the direction blocking the flow of the seawater.

Description

technical field [0001] The present invention relates to a construction method of an artificial seamount constructed by accumulating blocks on the seabed and an artificial seamount. Background technique [0002] In recent years, the following technology has been proposed. The purpose is to construct artificial seamounts on the seabed, and to use the flow of tidal currents or ocean currents to add nutrients rich in seawater below the compensation depth to the surface layer of seawater. Phytoplankton in the surface layer can use sunlight to proliferate, thereby achieving the purpose of proliferating phytoplankton as the source of the food chain. In the artificial seamount as described above, it is preferable to increase the projected area in the direction along which the seawater flows, that is, the cross-sectional area in the direction in which the seawater is blocked. Existing artificial seamounts are constructed by the following methods: For example, in order to make stones...
