Abstract

(57) [Abstract] [Purpose] A steel pipe sheet pile revetment provides a habitat for fish and aquatic organisms, and soil and rock wool, etc. containing plant seeds and nutrients are placed in that space. As a result, the plant can be grown. [Structure] An opening 2 is provided on the river side surface of the steel pipe sheet pile 1, or on the river side surface and the land side surface.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a steel pipe sheet pile revetment structure used in rivers and lakes.

[0002]

[Prior art]

 Conventionally, steel sheet pile revetments and steel pipe sheet pile revetments have been used as revetments for rivers and the like. For example, Japanese Utility Model Publication No. 1-39781 discloses a steel sheet pile revetment and a steel pipe sheet pile revetment.

[0003]

[Problems to be solved by the device]

 With the structure of steel sheet pile or steel pipe sheet pile, there is no closed space on the revetment, so there is no habitat for fish and aquatic life. In addition, because the river side and land side are cut off, no plants grow on the revetment surface.

[0004]

[Means for Solving the Problems]

 In order to advantageously solve the above-mentioned problems, in the steel pipe sheet pile revetment structure of the present invention, the opening 2 is provided on the river side surface of the steel pipe sheet pile 1, or on the river side surface and the land side surface.

Next, the operation of the present invention will be described. Since the opening 2 is provided on the surface of the steel pipe sheet pile 1 on the river side, the inside of the steel pipe serves as a habitat space for fish and underwater organisms, and a shelf plate 4 made of steel plate is attached to this space part to prevent plant Soil containing seeds and nutrients, and porous materials such as rock wool can be used to grow plants. Also, by providing the opening 2 on the land side of the steel pipe sheet pile 1, it is possible to maintain continuity between the land side and the river side such as the flow of groundwater.

[0006]

FIG. 1 shows a steel pipe sheet pile revetment structure according to an embodiment of the present invention, in which a tubular joint 6 with a slit is fixed to one side portion in the diameter direction of a steel pipe 8 by welding, and The steel pipe sheet pile 1 is constructed by welding the T-shaped cross-section joint 7 to the other side of the steel pipe 8 in the diametrical direction, and the steel pipe 8 has a river-side surface or a river-side surface and a land-side surface. An opening 2 is provided in the. A steel plate shelf 4 is fixed to the upper side of the plurality of steel pipes 8 by welding or the like, and the opening 2 and the shelf 4 are provided in a factory or at a place near the place where the steel pipe sheet pile 1 is placed.

The steel pipe sheet pile 1 including all the steel pipe sheet piles 1 having the openings 2 and the shelf plates 4 fixed as necessary has a tubular joint 6 with slits and a T-shaped cross-section joint 7 meshing with each other. The steel pipe sheet pile 1 having the shelf plate 4 is driven into the subseabed ground 9 in the above state, and above the shelf plate 4, above the shelf plate 4, the soil containing the seeds and nutrients of the plant, the porous material such as rock wool, etc. The material 5 is accommodated and the plant can be grown.

By providing the opening 2 also on the land side surface of the steel pipe sheet pile 1, it is possible to maintain continuity between the land side and the river side such as the flow of groundwater. Further, the inside of the steel pipe 8 serves as a habitation space 3 for fish and underwater organisms.

FIGS. 2 and 3 show examples of the shape and arrangement of the openings 2. In the case of FIG. 2, a large number of circular openings 2 are provided in a staggered manner, and in the case of FIG. A large number of slit-shaped openings 2 extending in the vertical direction are arranged in a staggered manner.

[0010]

[Effect of device]

 According to the present invention, since the opening 2 is provided on the river side surface of the steel pipe sheet pile 1 or on the river side surface and the land side surface, a habitat space for fish and aquatic organisms can be formed, and Plant growth can be promoted by placing plant seeds, soil containing nutrients, and a porous material such as rock wool in the space.
