[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel sheet pile revetment structure used in rivers and lakes.

[0002]

2. Description of the Related Art Conventionally, as a revetment for steel sheet piles in rivers and the like, a structure having a U-shaped steel sheet pile 16 meshed as shown in FIG. 7 is known. Japanese Utility Model Laid-Open No. 4-22510 discloses a technique in which a casing is attached to each of the recesses in the vertical direction on the river side of a cast steel sheet pile in order to improve the viewability of the seawall structure.

[0003]

[Problems to be Solved by the Invention] In the structure of the steel sheet pile as it is, the revetment surface has an irregular shape, but there is no closed space, so there is no space for fish and underwater organisms. Also, plants are not growing on the revetment because the river side and the land side are blocked. There is also a problem that the uneven shape impairs the landscape. In the disclosed utility model publication which proposes to improve the scenery, a casing for plant vegetation and a fish nest is attached to a steel sheet pile by welding or bolts, but the U-shaped steel sheet pile is targeted. And can only be installed after the steel sheet pile has been driven. For this reason, there is a problem that an installation operation on site and an underwater operation for mounting the casing in the underwater portion occur.

[0004]

In order to advantageously solve the above-mentioned problems, in the steel sheet pile revetment structure of the present invention, two Z-shaped steel sheet piles 1 are assembled via a joint 1a, and the vertical structure on the river side is provided. The steel plate 2 having the opening 2a is attached to the recess 1b in the direction. The above-mentioned problem can also be advantageously solved by providing an opening 11a in the straight steel sheet pile 11 and attaching a bent steel plate 12 so as to form a space 13 on the land side surface.

Next, the operation of the present invention will be described. Since the two Z-shaped sheet piles 1 were assembled via the joint 1a and the steel plate 2 having the opening 2a was attached to the river-side recess 1b,
A habitable space 3 for fish and aquatic organisms is formed, and a shelf plate 4 made of a steel plate is attached to the habitable space 3 to store a porous material 5 such as soil or rock wool containing plant seeds and nutrients. By doing so, the growth of plants can be achieved, and the revetment surface on the river side becomes planar instead of uneven, so that the landscape can be improved. Also a straight steel sheet pile 1
In the case of the invention of the second aspect using the first embodiment, the same operation as the invention of the first embodiment using the Z-shaped steel sheet pile 1 can be obtained.

[0006]

1 and 2 show a steel sheet pile revetment structure according to a first embodiment of the present invention, in which two Z-shaped steel sheet piles 1 are used in mesh with each other. Two Z-shaped steel sheet piles 1 are assembled via a joint 1a, and a steel plate 2 having an opening 2a is fixed by welding to a groove edge of a longitudinal concave portion 1b on the river side by welding, and thus integrated. The steel plate 2 and the Z-shaped sheet pile 1 are cast on the underwater ground 17. The steel plate 2 may be installed in a factory or may be installed on site before casting. By doing so, a habitat 3 for fish and underwater creatures is created.

The shape of the opening 2a of the steel plate 2 may be such that a number of circular holes are provided separately as shown in FIG. 5, or a slit extending in the lateral direction as shown in FIG. The openings 2a may be provided at intervals in the vertical direction.

As shown in FIG. 1, a shelf plate 4 made of a steel plate is attached to a steel plate 2 and a porous material such as soil or rock wool containing plant seeds and nutrients is placed on the shelf plate 4. By storing the material 5, the plant can be grown. In this case, by providing the steel sheet pile 1 with an opening, continuity of flow between the land side and the river side, such as the flow of groundwater, can be maintained.

3 and 4 show a steel sheet pile revetment structure according to an embodiment of the present invention, in which a straight steel sheet pile 11 is used, and the straight steel sheet pile 11 has a large number of openings. The steel plate 12 provided with the portion 11a and bent so as to form a habitable space 13 on the land side is fixed to the land side surface of the straight steel sheet pile 11 by welding and integrated, and the integrated straight line is formed. The shape steel sheet pile 11 and the steel sheet 12 are
In this way, a habitable space 13 for fish and underwater creatures is formed.

The shape of the opening 11a of the straight steel sheet pile 11 may be such that a large number of circular holes are provided separately as shown in FIG. 5, or extend in the lateral direction as shown in FIG. The slit-shaped openings 11a may be provided at intervals in the vertical direction.

As shown in FIG. 3, a shelf plate 14 is mounted on a steel plate 12 and a porous material 15 such as soil or rock wool containing plant seeds and nutrients is placed on the shelf plate 14.
May be accommodated. With such a configuration, plant growth can be achieved. In this case, by providing an opening in the steel plate 12, continuity of flow between the land side and the river side, such as the flow of groundwater, can be maintained.

[0012]

According to the present invention, two Z-shaped sheet piles 1 are provided.
Is assembled via a joint 1a, and a steel plate 12 having an opening 2a is attached to a longitudinal recess 1b on the river side, or an opening 11a is provided in a straight steel sheet pile 11, and Since the steel plate 12 bent so as to form the habitat 13 is attached to the land side surface, the habitats 3 and 13 for fishes and aquatic organisms can be provided.
By placing porous materials 5, 15 such as soil and rock wool containing plant seeds and nutrients in the habitats 3, 13, the plants can be grown, and the revetment surface on the river side is uneven. Instead of being flat, the shape becomes flat, so that the landscape can be improved. In addition, by installing the steel plates 2 and 12 for forming the habitat spaces 3 and 13 at the factory, it is possible to obtain an effect that both on-site work and underwater work are unnecessary.
