Description

[Detailed description of the device]

[Industrial applications]

 The present invention is a block that is used by being piled up on the slope of a river, etc., but the inside and outside of the block communicate with each other by holes in the front plate, and the holes in the block can be used for planting plants and for aquatic insects. It relates to a perforated block that serves as a doorway and is filled with stones to form a space in which organisms such as fish, shellfish, small animals, and insects can live.

[0002]

[Prior art]

 Uniform concrete blocks have been used for revetment of rivers. The revetment work using this block was very efficient and the disaster recovery was quick. As for the method of revetment, not only the slope but also the block was laid on the riverbed, and sometimes the three sides of the river were hardened with concrete. However, this method has come to be criticized for its river environment. The river space is topographically, ecologically, and environmentally very complex and diverse. Rivers are meandering rather than linear, and there are diverse streams that form streams and pools, preserving landscapes and rich ecosystems that are characteristic of rivers. From this point of view, the conventional river revetment straightened the meandering river and swept the water rapidly, and it was impossible to form a river or a pool. Most of the fish and shellfish that live in rivers have a relationship with the sea in their daily lives, and other things live while moving up and down the river. From this point of view, the longitudinal continuity of the river is important, and the repetition of the river and the pool is also important in relation to the longitudinal continuity. Furthermore, the continuity of water and land areas is also important, and habitats for amphibians such as aquatic insects and frogs are necessary.

[0003]

[Problems to be solved by the device]

 From this point of view, the current river revetment construction method covers the river with concrete blocks both longitudinally and transversely, resulting in discontinuity, which is extremely disastrous for seafood and aquatic life. It was a bad environment. From the above, it is necessary to provide an environmental space where aquatic insects, benthic animals and seafood can live.

[0004]

[Means for Solving the Problems]

 Therefore, the present invention has been proposed in order to eliminate the above-mentioned inconvenience, and a front plate and a rear plate shorter than the front plate are provided in a pair, and the plates are integrated by a connecting portion to form a front plate. To communicate with the inside through appropriate holes and gaps, a ridge is formed on the upper surface of the connecting portion, and a ridge can be fitted to the symmetrical lower surface, and a deep recess is formed. The upper surface of the front plate is slightly lower than the connecting portion to form the gap forming projection.

[0005]

【Example】

 Next, embodiments will be described with reference to the drawings. Reference numeral 1 denotes a front plate, and a rear plate 2 shorter than the front plate is provided opposite to the front plate, and the front plate 1 and the rear plate 2 are integrally formed by a connecting portion 3. Pseudolites 4 are appropriately formed on the front plate 1, and holes 5 are formed between the pseudolites 4 to communicate with the inside of the block. Reference numeral 6 is a protrusion formed on the upper surface of the connecting portion 3. Reference numeral 7 denotes a recess formed symmetrically with the ridge 6 on the lower surface, and is formed deeper than the height of the ridge 6. Reference numeral 8 denotes a gap forming projection formed by lowering the upper surface of the front plate 1 slightly lower than the connecting portion 3. Reference numeral 9 is a gap forming protrusion formed on both sides of the front plate 1. 10 is a basic concrete, 11 is a backfill material, 12 is a bodyfill material, 13 is a plant, and 14 is a small animal.

[0006]

[Action]

 Since the present invention has the above-mentioned structure, the front plate 1 is butt-aligned with each other on the basic concrete 10 to form the first stage, and then the second stage is composed of the two first stages. The block 7 is placed over the blocks, the protrusions 6 are fitted in the recesses 7 of the upper block, and the blocks are sequentially stacked in the same manner, and the inside of the blocks is filled with the body filling material 12 for processing. .

[0007]

According to the present invention, when the revetment is constructed by stacking as described above, a gap 8 is formed between the upper and lower sides of the front plate 1 by the gap forming projections 8 and the inner portion of the block is formed by the holes 5 of the front plate 1. The vegetation is possible inside the block, and the front surface of the block is covered by the plant 13 so that a revetment close to the natural environment can be constructed. In addition, seafood, small animals, insects, etc. can invade the inside of the block and serve as a habitat, maintain a living environment, and create an environment unprecedented. In addition, unlike the conventional case, the case of the present proposal has the effect of ensuring continuity with the water area and the land area, since it does not need to be filled with concrete. If the gap forming projections 9 are provided on the side faces of the front plate 1, gaps can be formed between the side faces of the side plate 1.
