Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a pseudo-seafloor structure provided at a location where fish and seaweed are likely to breed.

<Prior art> In general, sunlight is necessary for seaweed to propagate, and areas where seaweed propagates are suitable for growing and spawning fish and shellfish, making them good fishing grounds.

Therefore, because sunlight does not reach the ocean floor at a certain depth, seaweed does not grow, and as a result, fish and shellfish do not gather there.

OBJECT OF THE INVENTION The present invention has been made in this regard, and an object of the present invention is to provide a pseudo-seafloor structure that can be used as a fishing ground on the seabed with low productivity, which was conventionally unsuitable as a fishing ground. purpose.

Structure of the Present Invention The pseudo submarine structure of the present invention is composed of a pedestal 1, a floor plate 2 installed on the pedestal 1, and an artificial grass 3 laid on the floor plate 2.

Kui〉Installation of the pedestal on the seabed The pedestal 1 uses a steel pipe.

When constructing the pedestal 1, first, as shown in FIG. 2, a plurality of pipes 11 are connected by horizontal connecting members 12 and assembled into a triangular or quadrangular prism shape.

Then, the other pillar 1 is mounted on top of one # pillar l.

Then, the steel pipe pile 13 is suspended through the pipe 11 of the upper pillar 1, and the steel pipe pile 13 is driven into the seabed using the pipe 11 as a guide.

At the time of driving, as shown in FIG. 3, the m-tube pile 13 is driven using the extension member 14) to a height such that it is completely housed inside the pillar 1 of the lower stage.

<Exposure> Height of pedestal 1 There is a certain limit to the maximum height of pedestal 1 group after completion of pouring.

In other words, the lower limit of the height of the upper end of the pedestal 1 (on which the floorboard 2 is mounted) is the position at which an appropriate amount of sunlight can reach, and therefore, if it is too deep, the purpose of the present invention cannot be achieved. Can not.

On the other hand, if the top of the pillar 1 is too shallow, the sun's rays will reach the surface sufficiently, but the influence of waves will become too great, making it unsuitable for breeding seaweed.

Therefore, the upper limit of the height of this pedestal 1 is a height at which it is not significantly affected by waves.

<C> Connection between pedestals A large number of pedestals 1 are fixed to the seabed using the method described above or other known methods.

In this case, the adjacent pedestals 1 are not in contact with each other, but are spaced apart from each other by an appropriate distance, and are connected by a beam member 15 as shown in FIG.

Kuni〉Installation of floorboard 2 A floor plate 2 is installed horizontally on top of the completed 1 group of pillars.

This floor plate 2 is constructed from a concrete plate and is connected to the pedestal 1 by suitable known means.

Furthermore, as shown in FIG. 5, it is also possible to connect the footnotes 1 directly with the floorboards 2 instead of using the beam members 15.

In that case, there is no need to install another floorboard 2 later.

<E> Laying of artificial grass Artificial grass 3 is laid on the floorboard 2 having the above-described structure.

As shown in FIG. 6, artificial turf 3 is constructed by forming known artificial turf into a bag shape and filling the bag with sand 31.

By sinking and laying the bag-shaped artificial grass 3 containing filling sand 31 on the floorboard 2, all the floorboards 2 can be covered in a stable artificial grassland-like state. (Figure 1) Therefore, as time passes, various kinds of real seaweed seeds will grow between and around the artificial turf, and they will proliferate.

All kinds of fish then gather to feed on the seaweed, making it a good fishing ground.

Effects of the Present Invention> Since the present invention is as described above, the following effects can be expected.

The artificial grass should be laid at a location that receives moderate sunlight and is at a depth where it is hardly affected by waves.

Therefore, it is possible to breed fish and other species under ideal conditions.

If built on sandy mud areas with particularly low productivity, it can be turned into a good fishing ground.

Kuha〉The pedestal can be constructed from a hollow pipe, and the pedestal can be temporarily joined at the top and bottom and used as a guide to drive the pile.

Therefore, piles can be driven using the upper pedestal exposed above the sea as a stable guide, and there is no need to prepare a separate guide.
