吊り下げた状態を示す。Previously, this type of driving method was as follows: 1) Assembling steel sheet piles to create a cylindrical assembly cell at the assembly base on land and E;
) Each of the steel sheet piles is held between small chucks attached to an annular holding adapter, and the assembly cells are suspended by a crane on a starter ship.3) They are transported one by one to a destination at sea, where they are ground using a vibro. There is something to type inside. Figure 1 shows the individual steel sheet piles (2) of the assembly cell (1)...
.. the small chuck (4) of the annular retaining adapter (3).

It has the drawbacks of being time consuming and expensive.

１つ打ち込むたびに船が陸上基地との間を往復しなくて
もよいから、その点では打ち込みに時間と費用がかから
ない利点があった。Conventional driving methods include 1) welding into a cylindrical shape at a land base to create a single steel plate cell, 2) transporting the steel plate cells on multiple barges to a destination at sea, and 3) there. They are hoisted up by the crane of the launch engine ship and driven into the ground one by one. According to this driving method, the ship does not have to go back and forth from the land base every time one steel plate cell is driven, which has the advantage of reducing the time and cost required for driving.
ところが、この種の打ち込み工法では、鋼板セルをつく

セルに比してかなり高価となる欠点があった。そして、

なければならない困難があった。However, this type of driving method has the disadvantage that it takes a very long time to make the steel sheet cells, and it is considerably more expensive than assembled cells made by assembling steel sheet piles. and,
If as many steel plate cells as possible were to be made at the same time in order to shorten the time, there was naturally the difficulty of having to secure a land base for that amount.
なお、組立セルは、補助枠がなければそれ自体自立する

。In addition, since the assembly cell cannot stand on its own without an auxiliary frame, it is impossible to load a plurality of cells at once onto a barge and transport them to the destination like steel plate cells.

する如く筒状ｌ二組立ててなる。In the method of driving steel sheet pile assembly cells according to the present invention, first, steel sheet piles are assembled at an onshore assembly base to form a cylindrical assembly cell. The symbol (1o) in Fig. 2 is an assembly cell, and the assembly cell (10) is shown by connecting a plurality of straight steel sheet piles (12) of equal length in the width direction. It is made by assembling two cylindrical parts.

間隔につくられる。Next, each of the steel sheet piles is held between the small chucks of the holding adapter to hold the cylindrical shape of the assembly cell. That is, as shown in FIG. 3, the holding adapter (14) is made up of a plurality of small chucks (18) hanging from an annular base (16), and these small chucks (]8)... ...
The individual steel sheet piles (12) are held in place so that the cylindrical shape of the assembly cell (10) does not collapse. A plurality of chuck holding parts (20) are formed at equal intervals on the annular base (16) of the holding adapter (14).

It can be hung on the hook (38) through the. Hook (38)
is suspended by a wire (40) from a crane (44) of the launch machine ship (42). Therefore, the holding adapter (
14)'s chuck holding part (20)... is held between the large chuck (24)... and the starter boat (42) is held.
The assembly cell (10) with the holding adapter (14) attached thereto can be lifted by a crane (44) and lowered to a desired position from the barge (22). Thereafter, all the vibros (28) are driven in synchronization to drive the assembled cell into a desired position in the sea. After driving, the small chucks (18) are removed from the grip 1, and only the assembly cell (10) is buried underground.

ができる利点がある。Of course - m = 1 According to the driving method according to the present invention, a cylindrical assembled cell made by assembling steel sheet piles is used, so compared to the case of using a steel sheet cell that is made integrally by welding, the cell itself becomes smaller. It has the advantage that the manufacturing time can be much shorter and it can be manufactured at a lower cost. Furthermore, since it becomes possible to carry multiple such assembly cells onto a ship and transport them to the destination, there is no need for the starter ship to make a round trip to and from the land base each time one assembly cell is launched, which was previously required. This means that the construction period can be significantly shortened. Therefore, from this point as well, there is an advantage that construction costs can be reduced.
