BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure for covering materials, a revetment structure, and a method for constructing a revetment.

[0002]

2. Description of the Related Art Conventionally, for the construction of a revetment, a covering stone construction method of covering a rubble stone installed in water with a covering stone has been used.

[0003]

However, in the covering stone construction method, it takes a lot of time to process the covering stone to be used, and a large number of divers are required for leveling the rubble in the sea and installing the covering stone, resulting in a long construction period. There was a problem. As the construction period becomes longer,
The seawall under construction will be more likely to be damaged by the waves. In addition, it is expected that there will be a shortage of large-scale stone materials used for coated stones in the future.

The present invention has been made in view of the above problems, and an object of the present invention is to connect a revetment to a revetment which can cover the revetment in a short construction period and has good stability after coating, a revetment structure, and It is to provide a method of constructing a seawall.

[0005]

A first invention for achieving the above-mentioned object is a connecting structure of a covering material for covering a revetment, wherein a connecting member is connected to an engaging means provided in the covering material. This is a structure for connecting a plurality of coating materials by connecting the plurality of coating materials.

A mesh bag filled with a filling material is used as the covering material. A partitioning material or a middle connecting material that connects the upper portion and the lower portion of the mesh bag may be provided inside the mesh bag. The engaging means provided on the covering material is, for example, a hanging ring or an engaging tool having another structure, and is used as an engaging tool with the connecting member or as a jig for hanging on a crane or the like. If the engagement means are provided at the upper end of the dressing, each dressing is connected at the top. When the engaging means are provided at the upper end and the lower end of the covering material, the respective covering materials are connected at the upper part and the lower part. Further, the engaging means may be attached to the end portion of the belt-shaped material such as a rope provided in the lower half portion of the covering material. In this case, the coating materials are connected not only to the upper and lower parts but also to the side.

The connecting member connects the covering material and the covering material, or the covering material and another connecting member, and, for example, a shackle or the like is attached to an end portion of the main body composed of a chain or a connecting suspension ring. Fittings are provided. By changing the configuration of the chain, the connecting suspension ring, or the like, a connecting member having an arbitrary shape can be formed.

In the first aspect of the present invention, the connecting member is connected to the engaging means provided on the covering material to connect the plurality of covering materials.
By connecting a plurality of covering materials, the movement of each covering material due to waves can be suppressed after installation.

A second aspect of the present invention is a revetment structure characterized in that rubble stones are coated with a plurality of coating materials connected using the connection structure of the coating material of the first invention.

A third aspect of the present invention includes the steps of connecting a connecting member to the engaging means of the covering material to form a covering material connecting body, moving the covering material connecting body using a hanging device, and And a step of arranging the connected covering material body on the rubble stones.

The covering material connecting body is formed by using the covering material connecting structure of the first invention. The covering material connecting body is formed by connecting a plurality of covering materials in a linear shape or a polygonal shape. When suspending the covering material connected body using the suspending device, in order to suppress slack due to the weight of the connecting member, the covering material connected body is suspended while applying tension to the outside direction of the covering material connected body.

In the third invention, a plurality of covering materials are connected by using the connecting structure of the first invention, and the connected covering materials are installed on the rubble of the revetment. Since a plurality of covering materials are connected and installed on the seawall at once, it is easy to manufacture and install and does not require a long construction period.
