Therefore, there is a demand for improvement of a road for the referee vehicle in a competition held in a lake or the like. In particular, large-scale events such as international events require dedicated road facilities.

  Also, even if it is an artificial stadium, roads constructed along the course can be used by ordinary vehicles except during the period of the competition. The competition can be held in such a way that Although it is possible to block traffic at large-scale tournaments, it is difficult to block traffic at the citizen tournament level. Therefore, even for artificial courses, there is a need for a dedicated road for referee vehicles.

  As a floating body having a traveling path on which a vehicle can travel on an upper surface, a construction machine traveling path for a water reclamation method disclosed in Patent Document 2 has been proposed. This construction surface for construction of the surface reclamation method has a plurality of barges floating in parallel on the water surface, and a mounting seat having a concave portion at or near the center line of the upper surface of the plurality of barges in the parallel direction.
