Assembly equipment for long large steel plate unit and moving method of long large steel plate unit

The present invention relates to an assembly apparatus for a long large steel plate unit (cell) for constructing a bank or a land in a shallow water such as a bay shore or a coast, and a method for moving a long steel plate unit.

The steel plate unit is a structure that prevents erosion damage caused by tides or waves in the sea in the revetment or the landfill. For example, a plurality of cylindrical steel plate units are driven into or placed in the foundation at the outer periphery of the revetment or the filling site, and the steel plate units are connected to each other by arc steel, and the steel plate units or curved steel are connected to each other. The interior is filled with a filling material such as sand.

Here, the long-large steel plate unit refers to a tubular large-sized structure having an outer diameter of more than 15 to 50 m and a height exceeding, for example, about 20 to 40 m.

In the long and large steel plate units, a plurality of rolled steel sheets are first welded to form a flat long steel plate, and the long steel plates are bent into an arc shape to form a cell block. Further, the edge portions parallel to the axial direction of the unit blocks are welded to each other to be assembled into a cylindrical shape.

In the assembly of the unit blocks, for example, as shown in Patent Document 1, a curved surface forming table in which a long steel plate is supported in a curved concave shape is arranged in the outer peripheral portion around the assembly portion, and the long steel plate is placed on a curved surface. After forming a curved surface on the stage, the curved surface forming stands are erected with the vicinity of the outer periphery of the assembled portion as a fulcrum, and the edges of the curved steel plate are joined to each other and joined to each other, and finally processed into a cylindrical shape.

However, in the prior art, the curved surface forming stage is disposed so as to be radially spread around the assembly portion. Therefore, for example, a long large steel plate unit having a diameter of 30 m and a height of 40 m is occupied at least. The location above 110m square, and the larger the larger, the wider the location.

Further, when such long and large steel plate units are welded and joined in a vertical state, they are suspended by a floating crane and transported to the installation site by using a floating crane. Alternatively, a shipping barge is loaded into the multi-tank and transported to the installation site. However, in order to shorten the transportation time of the crane vessel or the transport barge and reduce the transportation cost, it is necessary to move from the assembly station to the temporary placement of the unit and temporarily place it. In this case, it is preferable to lift the steel plate unit while maintaining the shape. However, if a large crane or an oversized crane is used, there is a problem that the cost increases.

Furthermore, instead of the sliding jack 30 and the sliding pedestal 61, a so-called Chill Tank may be used, which has multiple rollings via a connecting rod. The shaft portions at both ends of the wheel are connected to form a ring-shaped rotating body.

Even in the above-described sliding pedestal 61, the same operational effects as those of the sliding jack can be exhibited.

[assembly site]

Since the assembly site (location) used as the steel sheet unit assembly equipment is a temporary harbor, it is a place of various shapes in a plan view, and is provided in consideration of many restrictions. In the first embodiment, it is a horizontally long rectangular assembly site 10o.

FIG. 14 is an assembly site of the steel plate unit assembling apparatus of the second embodiment, and the same members as those of the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted. The second embodiment is a rectangular location of the facing revetment (fabric) W in which the steel plate unit C can be lifted using a crane vessel, but is also an assembly site 70 which has a situation in which it is difficult to use the depth of one end side. In the assembly site 70, the arrangement of the mounting tables 11A and 11B and the first and second unit temporary placement fields 12A, 12B, 13A, and 13B is substantially the same as that of the first embodiment, but the first to fifth panels are temporarily placed. Tables B1~B5 are different.

In other words, in the assembly site 70, the rows of the fields 12A, 12B, 13A, and 13B are temporarily placed in the assembly stages 11A and 11B and the first and second units provided in the facing bank W, and are arranged in parallel with respect to the bank W. The first to third panels extending at right angles temporarily place the rows B1 to B3, and the fourth and fifth panels temporarily place the stations B4 and B5, and the deep side is once provided by the second and third lifting vehicles M2 and M3. The second or third panel temporarily places the B2, B3, or the fifth panel, and the unit block P2, P3, or P5, which is the unit block of the temporary placement table B5, is placed on the first panel temporary placement table B1 or the fourth panel temporary placement table. After B4, the unit block P2, P3 or P5 is erected, or the unit block P2, P3 or P5 is erected directly above it.

[Other Embodiments of Assembly Site]

Fig. 15 is an assembly site of the steel sheet unit assembling apparatus of the third embodiment, and the same members as those of the first embodiment are denoted by the same reference numerals, and their description will be omitted.
