There is no need for water treatment, and further labor saving can be achieved.

  Moreover, if the through-hole 40 is provided in the hollow part 22, the support member 62 straddling the plurality of panel members 12 is fixed by the support fixture 64 attached to the through-hole 40, and the panel member 12 is fixed to a predetermined height. Can be firmly fixed to the bottom surface and the side surface of the open channel 56. As a result, since the panel member 12 is less likely to float, it is not necessary to fill the backfilling material 68 in stages, the construction period can be shortened, and the buoyancy caused by the filling pressure of the backfilling material 68 can be reduced. Since the height of the member 12 does not change, the step can be reduced.

  Then, if lifting of the panel member 12 due to the backfilling material 68 is prevented by the support 62 attached to the support fixture 64, a panel other than the panel fixture 58 for fixing the panel member 12 to the existing structure is provided. Further, it is not necessary to attach the panel fixture 58 for preventing the lifting to the through hole 40, and the workability is improved.

  Further, if the panel member 12 is continuously fixed to the bottom surface and the side surface of the open channel 56 by the support work 62, and the height of the panel member 12 is maintained, the panel member 12 is fixed to the open channel 56. Not only is the strength increased, but the strength of the panel member 12 itself is also increased. For this reason, even if the thickness of the panel member 12 is reduced or the size thereof is increased, the panel member 12 is unlikely to float due to the filling pressure of the backfilling filler 68 and the panel member 12 is not easily damaged. As a result, by reducing the thickness of the panel member 12, the product cost of the panel member 12 is suppressed, and the cost is excellent. Moreover, by enlarging the panel member 12, the number and effort of attaching the panel fixing tool 58 can be reduced, and the workability is excellent.

  Further, when the cap joint portions 36 and 38 are provided in the recess portion 22 and the panel joint portion 46 is provided in the cap member 14, these are joined to form the upper surface of the cap member 14 and the first surface 24 of the panel member 12. The recess 22 can be covered with the cap member 14 so as to be flush with each other. Thereby, since the surface of the rehabilitation panel 10 becomes flush, when water flows on the rehabilitation panel 10, the flow of water is not disturbed by the surface of the rehabilitation panel 10, and the flow rate and flow rate of the water can be sufficiently secured. .

  In addition, if the water stop material 39 is attached to the cap joint portions 36 and 38, the recess 22 is covered with the cap member 14, and at the same time, the water stop material 39 provides a water stop between the cap member 14 and the panel member 12. Therefore, no water stop treatment is required and labor saving is achieved. In addition, the water stop material 39 does not fix the cap joint portions 36 and 38 and the panel joint portion 46, and the cap joint portions 36 and 38 and the panel joint portion 46 are fitted to each other. Since the cap joint portions 36 and 38 can be detached by joining the panel member 12, the panel member 12 can be fixed again and the workability is excellent.

  Then, after filling the backfill filler 68 between the bottom and side surfaces of the open channel 56 and the panel member 12, the support member 62 and the like are removed, and then the cap member 14 is left with a gap formed inside the recess 22. When the depression 22 is covered, the cap member 14 and the panel member 12 are easily deformed by the gap, and these are easily broken. However, before the depression 22 is covered with the cap member 14, the gap filling material is provided inside the depression 22. By filling 48, these problems are less likely to occur, so the reliability of the rehabilitation panel 10 is improved.

  Moreover, since the bottom face and side surface of the open channel 56 are covered with the renovation panel 10 and the backfill filler 68 is filled between them, and these are integrated, the structure 70 whose strength has been recovered is formed. .

  Further, the panel member 12 after being filled with the backfill filler 68 is held at a predetermined height, and the recess 22 is covered with the cap member 14, so that the surface of the renovated panel 10 is flush. Since the bottom surface and the side surface of the open channel 56 are covered with the renovated panel 10, the structure 70 whose surface is repaired is formed.
