There is an example of building. As shown in FIG. 12, the hollow cylindrical steel plate cell 1 used in the construction of this reclaimed seawall is constructed by arc welding a plurality of iron plates in a factory or production yard to construct an arc-shaped steel plate cell arc 2. Then, these steel plates are made by butt-welding the cell arcs 2, and after being manufactured, they are transported to a place of installation by a carrier ship, where they are suspended by a crane ship 3 via a placing device 4 as shown in FIG. It is lowered, and in this state, it is vibrated by the bi-blow hammer 5 and placed on the seabed.
In FIG. 13, 6 is a hanging jig, 7 is a shock absorber, 8 is a base ring, and 9 is a hydraulic chuck, which together with the above-mentioned blow blow hammer 5 constitute a driving device 4. The reclaimed seawall constructed by the above construction method can be constructed without using a large crane ship, but has an advantage that the construction is easy and the construction cost is low.

The placing device 4 which is indispensable for performing the above construction is increased in size, and the manufacturing cost for one Tsukishima box is relatively high. Vibro hammer 5, hydraulic chuck 9
A large number of accessories are required for the equal-placing device 4, and it is difficult to apply a uniform load and vibration to the steel plate cells by these devices. The crane ship 3 also needs a large one (for example, a 3000 ton class crane ship in the case of a steel plate cell with a diameter of 40 to 50 m), and since the number of islands is small, there is a problem that the traveling cost and damages for one box of Tsukishima are expensive. is there.

極めて容易に嵌合できることができる。Here, the steel plate cell arc 14 and the placing device 16 will be described. The steel plate cell arc 14 has substantially the same structure as the steel plate cell arc shown in the conventional example, and as shown in FIG. A flat plate obtained by butt welding is subjected to a bending process, the horizontal ribs 20 are attached to the upper end and the center of the obtained curved plate, and the flat plate is orthogonally attached to both side edges of the curved plate. 18
Is provided. And, this steel plate cell arc 14 is transported by a carrier ship to the construction site of Tsukishima after manufacturing,
Then, it is suspended and supported by the crane ship via the placing device 16. On the other hand, the placing device 16 is shown in FIGS.
As shown in the figure, a shock absorber 22 and a by-blow hammer 23 are attached to a suspension jig 21 formed by connecting flat plates in a triangular shape.
It is composed of a base 24 that is hung via a base plate and a hydraulic chuck 25 that is attached to the lower part of the base 24. The suspended object or the steel plate cell arc 14 is attached to the completed steel plate cell 19. Since it is small in comparison, the suspension fitting 21 and the base 24 may of course be small and lightweight, and the number of shock absorbers 22, vibrating hammers 23, and hydraulic chucks 25 may be small, and when suspending the steel plate cell arc 14, The work of adjusting them so that a uniform load is applied can be easily performed. Further, when fitting both side fitting portions 17 and 18 of the steel plate cell arc 14 to the fitted portions 12 and 13 of the steel pipe pile 11, the fitting portion 17 on one side was cut out in large numbers with an L-shaped cross section. By fitting the fitted portion 12 to the fitted portion 12, and then fitting the fitting portion 18 on the other side to the fitted portion 13 in which the L-shaped member in cross section is cut out small,
It can be fitted very easily.

さない等の利点がある。In the above example, the steel plate cell 19 is constructed by using the steel pipe pile 11 provided with the fitted parts on both sides, but as shown in FIG. 9 and FIG. A steel plate cell may be constructed by using a steel pipe pile 33 having a protrusion having the fitting portions 31 and 32 in contact with each other back to back.
In this case, when filling the steel plate cell with earth and sand, the tensile force acting on the fitting part via the steel plate cell arc is canceled between the fitted parts 31, 32 provided in contact with each other back to back. This is advantageous in that these forces are not applied to the steel pipe pile 33.
