DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to rivers, lakes, coasts,
Seawalls, valleys, etc. (In this specification, these may be simply referred to as “rivers, etc.”), revetment, slopes, etc. (including shallow riverbed, lakebed, and seabed structures in this specification,
Sometimes simply referred to as “bank protection structure”. ), In particular,
This is related to revetment structures aimed at preserving the natural environment.

[0002]

2. Description of the Related Art Conventionally, when a seawall such as a river is formed, concrete is poured along with the slope or a concrete block is installed along the slope to protect the slope. However, with the recent trend of preserving the natural environment, the method of using the above-mentioned conventional concrete is being reviewed, and the development of a method suitable for the natural environment has been demanded.

[0003]

In response to the demand for preserving the natural environment, a hollow concrete block in which a filler such as crushed stone can be filled has been proposed and put into practical use. I have.

However, since this block is made of concrete and is heavy and difficult to handle, not only is the workability at the time of construction inferior, but also the interior space is formed too large due to the strength required for the block. Therefore, the amount of filler that can be filled into the block is limited, and the purpose of preserving the natural environment by maintaining water permeability has not been completely achieved.

Further, in the case of a concrete block, a large number of small holes cannot be formed in the peripheral wall of the block. In many cases, the material cannot be used, and there has been a problem that the construction cost of the revetment including the transportation cost of the material increases.

The present invention addresses the problems of the conventional methods of casting concrete and installing concrete blocks and the hollow concrete blocks capable of being filled with a filler such as crushed stone. In view of the above, the amount of filler to be filled is increased by forming a large internal space, thereby maintaining good water permeability and preserving the natural environment. It is an object of the present invention to provide a revetment structure in which there is no restriction on the size of the lumber and the construction cost of the revetment including the transportation cost of the material can be reduced.

[0007]

In order to achieve the above-mentioned object, a revetment structure of the present invention is constructed by connecting a tubular body made of expanded metal on a net made of expanded metal laid on a revetment. Filling the inside of the tubular body with a filler such as crushed stone, laying a net formed by knitting a metal wire on the filler, and connecting the lower and upper nets to the tubular body It is characterized in that it is integrated by using. In this case, the revetment structure shall include shallow riverbed, lakebed, and seabed structures in addition to the slope.

In this revetment structure, a tubular body made of expanded metal is connected and laid, and the inside of the tubular body is filled with a filler such as crushed stone, so that the thickness of the steel material used is adjusted. The required strength can be easily obtained simply by increasing the amount of filler to be formed by forming a large internal space, thereby maintaining good water permeability and preserving the natural environment. it can. In addition, the tubular body made of expanded metal is lighter in weight and easier to handle than a concrete block, and the connection work between adjacent tubular bodies can be easily performed. It is possible to cope with various kinds of fillers only by adjusting the size of the through-hole formed in the peripheral wall, and the construction cost of the revetment including the transportation cost of the material can be reduced. In addition, by laying the tubular body made of expanded metal on the net made of expanded metal laid on the seawall, it is possible to prevent the filler filled inside the tubular body from flowing out. , The expanded metal mesh laid on the revetment has a large movement resistance against the tubular body, so the laid state of the tubular body is stabilized, and the bottom of the tubular body itself needs to be formed. Therefore, the manufacturing cost of the cylindrical body can be reduced. Furthermore, by laying a net formed by knitting a metal wire on a tubular body made of expanded metal, it is possible to prevent the filler filled inside the tubular body from flowing out, Since the mesh body formed by knitting metal wires has a smooth surface, it is safe without injury even when a person walks on it, and a lid is formed on the tubular body itself. Since there is no need, the manufacturing cost of the cylindrical body can be reduced.

In this case, the lower and upper meshes,
The tubular body and the connecting member can be made of stainless steel.

[0010] This makes it possible to provide a seawall structure that does not rust and has durability.

[0011] Further, a metal wire spirally formed in the connecting member can be used.

Thus, the lower and upper nets and the cylindrical body can be easily connected and integrated at the site.

Further, a metal wire is inserted into the upper net along the upper end edge of the tubular body, and the metal wire and the tubular body are connected using a spirally formed metal wire. ,
The upper net and the tubular body can be integrated.

Thus, the upper net formed by knitting the metal wires and the tubular body can be easily and reliably connected and integrated at the site.

[0015] A nonwoven fabric having water permeability can be laid under the lower net.

This makes it possible to prevent the movement of earth and sand, stabilize the laying state of the tubular body, and provide a seawall structure having durability.

Further, the boundary between the inclined portion such as the slope portion and the horizontal portion such as the top end and the sagging portion can be formed so as to be linear.

Thus, the laid state of the tubular body in the boundary region between the inclined portion and the horizontal portion is stabilized, and a seawall structure having durability can be provided.
