Embodiment Construction
[0021] exist figure 1 In the schematic diagram of the artificial sea cucumber reef shown, the artificial sea cucumber reef is composed of some rough stones 1 placed on the seabed and at least one concrete prefabricated part 2. Two ropes and one rope 3 are arranged on the concrete prefabricated part. A signboard 4 and a buoy 5 are arranged on the top, and another rope is connected with the adjacent fish reef concrete prefabricated part to be the construction datum line 6 or the construction waterline 7.
[0022] The preparation method of the present invention is specifically as follows: first design the fish and reef distribution map of this predetermined sea area on the drawing, as figure 2 As shown in the figure, there is a grid with a spacing of 15 meters, and the intersection of the grid lines is the designed fish reef position. Select two endpoints A and B of the construction reference line 6 with GPS preliminary positioning, and drop concrete prefabricated parts to the ...

The invention relates to an artificial sea cucumber fishing rock, which consists of ashlars and concrete prefabricated elements placed onto the seabed, wherein two ropes are arranged on the concrete prefabricated elements, sign boards and floating marks are arranged on one rope, and the other rope is connected with the concrete prefabricated elements of the adjacent fishing rock. During the manufacture, two end points of the construction reference line are primarily positioned through a global positioning system (GPS) according to a designed fishing rock distribution figure, the concrete prefabricated elements are placed to the seabed of the two end points, then, the accurate positions of the two prefabricated elements are marked onto the fishing rock distribution figure by the GPS, a buoyancy construction reference line is arranged between the two floating marks, and fishing rock placing marks are arranged on the construction reference line. Construction waterlines parallel to the reference line are in additional arrangement, and fishing rock placing marks are arranged on each construction waterline. A pile of ashlars and concrete prefabricated elements are placed onto the seabedunder each fishing rock placing mark, each pile of ashlars is positioned through the GPS, and actual positions of the ashlars are marked onto the fishing rock distribution figure. The artificial sea cucumber fishing rock has the advantages that the positioning is accurate, the finding is convenient, and the construction method is simple.
Description
technical field [0001] The invention relates to a seafood farming site and a construction method. Background technique [0002] Artificial sea cucumber reefs are concrete prefabs or piles of rocks that people build to serve as sea cucumber habitat. At present, the production method of artificial sea cucumber reefs is: first design the distribution map of fish reefs on the blueprint, use GPS (satellite positioning system) to locate at sea, and then use reef-casting boats to drop rough stones to selected locations. The disadvantage of this method is: due to the influence of sea wind, waves and tidal currents, accurate positioning is very difficult, the error is generally in the range of 10-50 meters in radius, and the distance between the general release of fish and reefs is 10-20 meters, so the actual release effect Unable to control. Contents of the invention [0003] The purpose of the present invention is to provide an artificial sea cucumber reef with accurate positio...
