岸として改築するには費用が嵩むだけでなく工事も長期
に亘るなど種々の解決すべき課題があった。On the other hand, in recent years, not only the landscape has been emphasized but also the formation of a hydrophilic coastal area which is friendly to water and is friendly to human beings. It can be said that it is not appropriate and it is preferable to renovate or construct a revetment with a gentle slope, that is, a so-called gentle slope revetment. However, it is not only expensive to build such a conventional vertical revetment structure as a gentle slope revetment, but also long-term construction work is required to solve various problems, not to mention building a gentle slope revetment from the beginning. was there.

It is possible to further facilitate the construction of landscapes by the combination of moving and large and small. It is also preferable to plant a salt-tolerant plant on artificial rock, since it is possible to improve the landscape and hydrophilicity.

ある。According to the method for constructing a gently sloped revetment according to the present invention, not only the construction cost can be reduced, but also the simplification of construction can be achieved because the wave-breaking solidification blocks and construction waste used for the existing revetment are used. Can also be achieved.

でもない。Next, a preferred embodiment of a method for constructing a gentle slope revetment according to the present invention will be illustrated and described in detail below. The method of the present invention is not limited to this embodiment. For example, the method of the present invention can be diverted to the construction or renovation of various types of embankments such as a breakwater, a jetty, a submerged embankment, and a dike. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention.

のまま中詰め１４ｂとして使用する。Referring to FIG. 1, in the method for constructing a gentle slope revetment according to the present invention, first, a wave-breaking block 1 used in an existing revetment 10 which has become unnecessary due to a redevelopment plan or the like.
Part or all of 2 was once removed by a hoist ship, etc.
It is installed as a solidification 14a of the tip portion of the gently sloped revetment 14 to be formed and a center filling 14b of the revetment 14 main body. It should be noted that the remaining wave-absorbing root compaction block 12 is used as it is as the middle filling 14b.

詰め１４ｂを形成することもできる。In some cases, not only the wave-breaking block used in the existing revetment 10 but also construction waste material generated at a construction site or the like can be used to form the tip-side packing 14a and the filling 14b.

保も図ることができ好適である。When the leveling of the covering is completed in this way, artificial rocks 18 are installed at appropriate places in the upper part to form the gentle revetment 14. In this case, if necessary, if artificial rock made of high specific gravity concrete using iron ore as an aggregate is used, wave resistance is improved, construction is simplified by downsizing the shape, and safety is further improved. It is also preferable because it is possible to secure the same.

A wave-dissipating root consolidation block having a fish nest function can be installed at the end of the tip root consolidation 14a as required.
【００１３】なお、本実施例では既設護岸１０を緩傾斜

Since it is used as solidification and filling, it can reduce construction costs and shorten the construction period.
Furthermore, since artificial stones and artificial rocks manufactured in factories and production yards are used, submersion and installation work can be performed efficiently and reliably, and accordingly, seawalls according to the design plan can be constructed. .
