In addition, when removing the scaffolding board from the wetland, the lower surface of the scaffolding board strongly adheres to the viscous sand and mud of the wetland and is difficult to peel off, and extra labor is required to peel the scaffolding board from the sand and mud of the wetland. May be required.

In Patent Document 1, a plurality of rectangular plate-shaped blocks made of synthetic resin are connected vertically and horizontally to form a floor plate, and the floor plate is laid on a target wetland or soft ground to allow the passage of people and vehicles. The technology that made it possible is described.

By applying such a floor board to a wetland such as a tidal flat and laying it as a scaffold so as to extend from the land side to the work point of the wetland, the load from the worker can be supported by the floor board, and the work point can be supported. It is possible to carry out work such as natural environment surveys in a stable state.

Since the synthetic resin block constituting the floor plate described in Patent Document 1 has sufficient rigidity and area, it is not deformed by the load from the operator, and the load from the operator. Does not sink into the wetland. In addition, since the synthetic resin block is lightweight, it is possible to easily carry it into the wetland and lay it down, and remove it from the wetland.

However, since the structure of the connecting portion of the block is complicated, it takes time and effort to manufacture, and the cost as a product increases. Further, since a plurality of blocks are connected vertically and horizontally to form a floor plate, it takes time and labor to connect the plurality of blocks. In addition, the lower surface of the block adheres to the viscous sand and mud of the wetland and is difficult to peel off, and extra labor may be required to peel off the block from the sand and mud. Further, since the rectangular plate-shaped block is stored in a warehouse or the like as it is or transported by a vehicle, a large space is required for storing and transporting the block.
