Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a sedimentation work for the purpose of revetment of a river.

[0002]

[Prior art]

 A revetment method has been conventionally known in which a frame frame made of logs is sunk on the riverbank and stone blocks are filled in it to fulfill the functions of root consolidation and water control. According to this method, willows and good plants grow on the stone blocks, and fish and insects inhabit the stone blocks, thus preserving the natural environment to some extent. However, there is a problem in the conventional floor sinking work that many people are required to assemble the frame.

[0003]

[Problems to be solved by the device]

 The present invention aims to provide a sinker that is easy to assemble.

[0004]

[Means for Solving the Problems]

 A column is erected at the center of each side of the top surface of the concrete block. The rods with holes at both ends are made to pass through the holes, and there is a space between the upper and lower rods, and the rods are assembled in multiple stages to form a frame. After placing such blocks side by side in the river, stone blocks are packed into each frame.

[0005]

[Action]

Consolidation of rivers is carried out with the respective weights of the basic concrete block and the stone blocks. Plants such as willow and Yoshi grow on the stone blocks, and fish and insects inhabit the stone blocks.

[0006]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. The basic concrete block 1 is formed in a box shape. It weighs about 2.4 tons. A space 2 is provided on the lower surface of the block 1 so that fish can enter, and a hole 3 is formed from the upper surface toward this space.

A screw cylinder 5 is embedded in substantially the center of each side of the upper surface of the block 1, and the frame body 6 is assembled on the block by using this. When assembling the frame body 6, first, the support column 7 is screwed into the screw cylinder 5 to stand up. The stanchion 7 may be a simple steel rod with an external thread.

Several rods 9 having holes at both ends are prepared, and the rods 9 are alternately stacked by passing the columns 7 through the holes at both ends to form a frame body 6 in a cross beam shape. Since the rods 9 are stacked alternately, a gap for one rod is formed between the upper and lower rods 9, and fish and insects can pass through this gap. The stacked rods 9 are fastened with nuts 10 screwed onto the columns 7.

The rod 9 may be made of log, square bar, channel steel or the like. In the case of logs, the diameter is about 120 mm, for example. The height of the frame body 6 depends on the conditions of the river to be installed, but in this embodiment, the rod bodies are stacked in four stages to a height of 480 mm.

After the frame body 6 is assembled in this manner, the blocks 1 are installed side by side vertically and horizontally in a river as shown in FIG. The blocks are connected to each other using a connecting fitting 11. After the blocks are installed, the stone blocks 12 are packed in each frame 6. The stone mass 12 is of a size that does not pass through the gap between the rods 9. In the seawall thus formed, the stone blocks 12 packed in each frame 6 form a stream, and the space 13 surrounded by the frame 6 of the adjacent block 1 becomes a pool, which is preferable for water birds and fish. Create a rich habitat.

[0011]

[Effect of device]

 The sinker of this invention has pillars standing on a foundation concrete block, and rods with holes at both ends are passed through the holes. Since the frame body is formed by assembling it, the frame body that puts the stone blocks on the basic concrete block can be easily assembled, and the construction cost is low accordingly. In addition, since there is a basic concrete block, it is comfortable to sit on, and because it adheres closely to the riverbed, it is effective in preventing scouring of the riverbed.

[0012] Furthermore, since the support columns are erected at substantially the center of each side of the upper surface of the block, when viewed from above, the frame body is formed only on the central portion, not on the entire upper surface of the block. When arranged, a space is created between the frame bodies. This space creates a pool, while the stone blocks in the frame create a stream, which can provide a habitat rich in change that is preferable for water birds and fish. Moreover, since the frame is smaller than the basic block, the material cost is low when using wood for the rod.
