Description

  The present invention relates to a fiber gabion incorporating pseudo sweet potato (seaweed).

  There are a number of depressions made by collecting earth and sand in the inner bays of the country, and in these depressions, there is a concentration of domestic and industrial wastewater, and the oxygen-deficient state of hydrogen sulfide water generated from domestic and industrial wastewater is dangerous. The benthic animals in the Ogikubo and surrounding waters are killed, and the influence on the fishery caused by the blue tide generated by floating the water of the Ogikubo in the sea surface caused by the tide and wind direction is regarded as a problem. ing.

  Currently, the conservation and regeneration of tidal flats and seaweed beds are being studied based on measures such as wastewater treatment and inflow water regulation in land areas, and research results that re-evaluate the water purification capacity of inner bays, but only measures that take a long time. The importance of rushing back the Ogikubo area has been pointed out.

On the other hand, the rocky place on the waterfront line was naturally washed by the rushing waves and the surface of the rock was shaved, but now, civil engineering structures that have been artificially constructed in that area have been built since the Showa 50s. As represented by a water breakwater, 30 years after the construction, sand under the foundation structure is sucked out from the scouring of breaking and pulling waves, and the civil engineering structure of the main body is destroyed from the scouring, so-called scouring I have made depressions everywhere.

In addition, the phenomenon caused by the Ogikubo area described above is the result of people expanding their place of life in the estuary, such as landfills, and the occurrence of the Senbori depression is a dam constructed to adjust the water level of the river as a flood countermeasure. This is also due to the fact that the gravel on the land was blocked without flowing into the sea, and the waterline was thinned, affecting the natural world. This natural chain has scoured nature's nagisa on the sea side, and the seaweed basin has been drastically reduced due to the decrease in Nagisa waters. The role of the seaweed basin was not only the ecological chain house, but also the role of flexibly softening the wave movement that soars and sucks out the sand gravel.

Thus, the present invention relates to a fiber gabion incorporating pseudo sweet potatoes (seaweed). The present invention incorporates a carbon fiber pseudo candy into a fiber gabion, and the fiber gabion incorporating the carbon fiber pseudo candy is used as a landfill material for the Ogikubo and Senbori pits, and for artificial candy field cultivation after landfill. Used as a material to form an artificial algae basin, conserve the Nagisa waters, promote natural algae basins, and prevent the seaside scouring pits from advancing and preventing the occurrence of blue tides It is.

  The problem to be solved by the present invention is that the fiber gabion and carbon fiber are used in the shallow sea area around the extremely damaged Ogikubo and Senbori depressions, especially for all the natural sea bream growing areas along the shoreline such as the inner bay. Made of artificial sea bream (seaweed) and the use of fiber gabion incorporating the carbon fiber artificial sea bream as a reclaimed material for Ogikubo and Senbori depressions, or artificial mama ground after landfill of Ogikubo and Senbori depressions An artificial seaweed basin is used as a material for cultivating seawater, conserving the waters of Nagisa, promoting the growth of natural seaweed basins, and preventing the advance of the scouring depressions on the sea side and the occurrence of blue tides To do.

The present invention is to make a gabion by filling a fiber gabion net with a concrete lump, and to make a gabion made of carbon fiber into the gabion to form a wave-dissipating / hardening block gabion. Can be used as a reclaimed material for the Ogikubo and Senbori depressions, or by using the fiber gabion that incorporates the carbon fiber artificial lintel as a backfill material for the Ogikubo and Senbori depressions. An artificial seaweed basin is used as a material for cultivating seawater, conserving the waters of Nagisa, promoting the growth of natural seaweed basins, and preventing the advance of the scouring depressions on the sea side and the occurrence of blue tides Made possible.

Further, in the present invention, not only the wave-dissipating / hardening block gabion incorporating the above-mentioned pseudo sweet potato is used as a backfill material for the Ogikubo and Senbori depressions, but also the landfill after the backfill of the Ogakubo and Senbori depressions. We provided a fiber gabion that incorporates a simulated lintel that was laid as a subsidence breakwater in the subtidal zone in front of the quay to create an artificial arbor ground.

Thus, the present invention makes a gabion by filling a fiber gabion net with a concrete lump, and incorporates a pseudo candy made of carbon fiber into the gabion to form a wave-dissipating / solidifying block gabion. By forming artificial seaweed beds with root-blocked block gabions, it becomes possible to conserve the waters of Nagisa, which in turn promotes the growth of natural seaweed beds, and further expands and expands the scouring depressions on the sea side. It became possible to play a role to prevent the transformation.

The sea is located on all sides of Japan and has been a common spiritual asset of Japanese people since ancient times, and has nurtured culture and civilization. However, in the era of high economic growth, it has been very active in the civilization for the past 50 years. I have done it. In the last 50 years, there has been an invisible impact, and many problems are now visible. From now on, it is necessary to change to a sustainable age, and the sea is required to play an active role in the area of culture. The formation of an artificial candy field and artificial nagisa is a method of quickly maintaining and repairing an extremely damaged place with the technology of the present invention in order to regain its original appearance of the sea. In addition to preventing the advancement and expansion of the Senbori depression, it has a great effect on the reclamation of the Ogikubo area that causes the occurrence of the blue tide and the environmental conservation around the Ogikubo area.

In addition, the formation of artificial sweet potato fields and regenerated natural seaweed beds in the present invention can be expected to increase the productivity of near-sea fisheries and bring the benefits of rich seas to the people.

It is a side view explaining the wave-dissipating / hardening block gabion using the fiber gabion net of the present invention. It is sectional drawing which shows an example of the artificial nagisa which implemented this invention.

Although the water quality purification ability of the ecosystem chain by various species living in the inner bay has been corrected over a long period of time, including landfilling in the inland sea since ancient times, human and natural symbiosis have been maintained. The development speed of the inland sea due to the high growth since the 1980s has not been able to catch up with the correction ability of the natural world, and the ecosystem has become almost impossible to regenerate.

Although this phenomenon was pointed out by experts from an early stage, what the public understood was today after 50 years of development, when witnessed catastrophic symptoms. There is now an urgent need to rush and deal with catastrophic symptoms from the technical stock accumulated over the past 50 years.

It is to change.

That is, the present invention is to make a gabion by filling a fiber gabion net with a concrete lump, and to make a gabion made of carbon fiber into the gabion to form a wave-dissipating / hardening block gabion. By using block gabions as a backfill material for Ogikubo and Senbori depressions, fiber gabions incorporating the carbon fiber artificial candy can be used as landfill materials for Ogikubo and Senbori depressions, The artificial seaweed basin is used as a material for cultivating the ground, conserving the waters of Nagisa, and promoting the natural seaweed basin. It is possible to prevent.

Further, in the present invention, not only the wave-dissipating / hardening block gabion incorporating the above-mentioned pseudo sweet potato is used as a backfill material for the Ogikubo and Senbori depressions, but also the landfill after the backfill of the Ogakubo and Senbori depressions. It is intended to provide a fiber gabion that incorporates a simulated lintel that is laid as a subsidence breakwater in the subtidal zone in front of the quay to create an artificial arbor ground.

Furthermore, the present invention is to make a gabion by filling a fiber gabion net with a concrete lump, and to incorporate a quail muffler made of carbon fiber into the gabion to form a wave-dissipating / solidifying block gabion. Use block gabions as backfill materials for Ogikubo and Senbori depressions, or lay out the wave-dissipating and root-blocking block gabions as subsidence breakwaters in the tide zone after backfilling the Ogikubo and Senbori depressions that fill the revetment. This will provide a construction method for an artificial sweet potato field that creates an artificial sweet candy field.
