Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fish nest block which is formed on a shore of a river or the like to form a seawall and, at the same time, has a fish nest inside so as to be a habitat for living organisms such as fish. It is.

[0002]

2. Description of the Related Art In a conventional block of this type, a space is formed or a hole is formed in a block to form a space by a combination of blocks. By doing so, the space became uniform in size, and although it was effective as a refuge for fish during floods, it was not very effective as a place for fish to live, lay eggs, and grow larvae during normal times However, the scenery was not good.

[0003]

Therefore, in order for the revetment with a pile block to be a comfortable space for fish to inhabit, there are various spaces inside the block, and there is an appropriate shaded portion. It is necessary to reduce the flow of water inside the turret, to provide a habitat for aquatic organisms, and to allow the flowing water to flow freely up and down, left and right, and to allow fish to freely move in the space inside the block.

[0004]

SUMMARY OF THE INVENTION The present invention has been proposed to solve the above-mentioned problem, and has a structure in which a rear plate is provided at a rear portion of a bottom plate and a predetermined interval is provided on the bottom plate. A partition shelf is provided, a connecting plate is provided at a quarter position from both sides of the bottom plate, and a retaining wall is integrally formed on the rear surface, and a large number of insertion holes are provided in the partition shelf. In implementation, a wooden stake or the like is inserted into the insertion hole to form an appropriate shaded portion inside, and the inside is a habitat.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the block of the present invention, a back plate is provided at the rear of a bottom plate, partitioning shelves are provided at regular intervals on the bottom plate, and are located at quarter positions from both sides of the bottom plate. A connecting plate is provided, and subsequently, a buttress wall is integrally formed on the back surface, and a number of insertion holes are provided in a partition shelf. This will be described in Examples 1 and 2 below.

[0006]

Embodiment 1 A first embodiment of the present invention will be described with reference to the drawings. The block 10 is provided with a rear plate 12 at a rear portion of the bottom plate 11 with a slight inclination, a partition shelf 13 provided on the bottom plate 11 at regular intervals, and a quarter from both sides of the bottom plate 11. Is provided with a connecting plate 14, followed by the rear plate 1.
2, a notch wall 15 is integrally formed, a number of insertion holes 16 are provided in the partition shelf 13, notch portions 17 are provided on both sides thereof, and a communication hole 18 is formed in the bottom plate 11, and notches are provided on both sides thereof. Part 19
Is provided, and a connecting horizontal hole 20 is formed in the connecting plate 14 so that the connecting plate 1
4, a projection 21 is provided on the upper surface, and a recess 22 is provided on the symmetric lower surface.

[0007] To implement this, the basic concrete 2
3, the side faces of a large number of blocks 10 are aligned in parallel,
When the wooden pile 24 is inserted into the insertion hole 16, and the upper stage is placed across the two lower blocks 10, 10, the protrusion 21 of the lower stage block 10 and the recess 2 on the lower surface of the upper stage block 10 are formed.
2 is fitted. Then, the wooden pile 24 is inserted into the insertion hole 16, and the pile is sequentially piled up while being filled with the stuffing concrete 25 on the back surface.

[0008]

Embodiment 2 Next, a second embodiment will be described with reference to the drawings. The block 30 is provided at the rear of the bottom plate 31 with a rear plate 32 standing upright, a partition shelf 33 is provided on the bottom plate 31 at regular intervals, and is located at a quarter position from both sides of the bottom plate 31. A connecting plate 34 is provided on the rear plate 32, and a retaining wall 35 is formed integrally with the rear plate 32.
6 and notches 37 are provided on both sides of the bottom plate 31.
Cutouts 38 are provided on both sides of the connecting plate 34, communication lateral holes 39 are formed below the connecting plate 34, recesses 40 are provided on the upper surface of the connecting plate 34, and projections 41 are provided on the upper surface of the retaining wall 35 on the rear surface. The groove 42 is provided on the symmetric lower surface.

In order to implement this, as in the second embodiment, the side surfaces of a number of blocks 30 are butt-connected in parallel on the foundation concrete 43, and a wooden pile (not shown) is inserted into the insertion hole 36.
, And the upper row is the lower two blocks 30, 30.
, The protrusion 41 of the lower block 30 and the concave portion 42 on the lower surface of the upper block 30 are fitted. Then, a wooden pile is inserted into the insertion hole 36, and the pile is sequentially piled up and filled while filling the back side with concrete.

[0010]

According to the present invention, the blocks are neatly masonry,
Constructs a strong seawall with projections and recesses, and various spaces are formed inside the block by connecting plates, partition shelves, and wooden piles inserted into the partition shelves, so moderate shading inside the block Water flow is reduced, water flows vertically and horizontally through the communication horizontal holes and notches, fish and other creatures can move freely, and it accumulates on wooden piles inserted inside blocks and partition shelves. The aquatic vegetation is promoted by the plants that have taken root in the sediment, thereby inhabiting the organism, spawning,
This has the effect of making it a good place for growing infants.
