And the seawall base material 41 is
And the pallet table 48 is moved in accordance with the filling speed of the revetment base material 41, so that the base material supply port 52 relatively moves to the base material filling port 53 of the tubular bag body 51. At the time of being pulled out, the supply of the seawall base material 41 is stopped, and then the base material filling port 53 of the tubular bag body 51 is closed,
They were producing flexible seawalls.

る。When a plurality of tubular bag bodies 51 are integrally provided on a base cloth 54 to manufacture a seawall material unit (see FIG. 2), a seawall base for one tubular bag body 51 is required. After the filling of the material 41 is completed, the air-based substrate supply device 46 or the pallet table 48 is moved in the lateral direction, and the above-described procedure is sequentially performed.
The adjacent tubular bag body 51 is repeatedly filled with the seawall base material 41,
The base material filling port 53 of the tubular bag body 51 is closed.
