Description

  The present invention relates to an assembly facility for a long steel plate cell and a method for moving the long steel plate cell for constructing a revetment or a landfill site in a shallow water area such as a bay coast or a coast.

  A revetment or landfill is a structure that prevents erosion and destruction caused by tidal currents and waves in the sea area.For example, a plurality of cylindrical steel plate cells are placed or installed on the outer periphery of the revetment and landfills. They are connected to each other with an arc, and each is filled with an interstitial material such as earth and sand.

  Here, the long steel plate cell refers to a cylindrical large structure having an outer diameter exceeding 15 to 50 m and a height exceeding about 20 to 40 m, for example. In these long steel plate cells, a plurality of rolled steel plates are first welded to form long steel plates (flat plates), and these long steel plates are bent into an arc shape to form cell blocks. Furthermore, the edge parts along the axial center direction of these cell blocks are welded together to be assembled into a cylindrical shape.

  Conventionally, for assembling these cell blocks, for example, as shown in Patent Document 1, a curved surface forming table that supports a long steel plate in a curved concave shape is arranged radially on the outer periphery of the assembly portion, and the long steel plate is placed on the curved surface forming table. After forming the curved surface, the curved surface forming table is raised up with the vicinity of the outer periphery of the assembly portion as a fulcrum, and the edges of the curved steel plates are butted together and finished into a cylindrical shape.

Japanese Patent Publication No. 01-25842 (Figure 1)

  However, in the conventional configuration, since the curved surface forming base spreads in four directions around the assembly part, the long steel plate cell having a diameter of 30 m and a height of 40 m occupies a site of at least 110 m square. There was a problem that the larger the size, the larger the site required.

  In addition, when such long steel plate cells are assembled by welding in a vertical position, they can be suspended by towing one box using a hoist ship, or loaded into a carrier carrier for each box. They are transported to the site. In order to shorten the usage time of the hoist ship and the transportation carrier and reduce the cost, it is necessary to temporarily move the assembly to the cell temporary storage place. In this case, it is ideal to lift the steel plate cell while maintaining its shape. However, if a large crane ship or a super large crane is used, the cost increases.

  Furthermore, in conventional devices that move large heavy objects such as bridge girders, winches are constructed by laying multiple rails, placing multiple heavy platform with endless rollers that support the lower end, and placing them on the moving end of the rail. Thus, it is known that a movable base is connected via a wire rope, a rope is wound up by a winch, the movable base is pulled, and a large heavy object is moved along a rail. However, when this is applied to a long steel plate cell and when at least two moving platforms are connected by a wire rope on one rail, the steel plate cell is moving due to the radial elasticity and inertial force of the steel plate cell. In addition, the distance between the moving bases cannot be maintained evenly, and the cylindrical shape may be deformed, which may adversely affect the structural portion and the joint portion of the steel plate cell.

  An object of the present invention is to solve the above problems and provide an assembly facility and a moving method for a long steel plate cell that can be efficiently assembled in a narrow assembly yard even for a long steel plate cell.
