Accordingly, the locking portion 42 hits the far end 18b of the recess 18 of the preceding non-curved wall rehabilitation panel member 38a. Therefore, when the main body 16 is pushed down with the first end 12 of the main body 16 as a fulcrum, FIG. Thus, the latching | locking part 42 enters into the inside of the hollow part 18 of the renovation panel member 38a for preceding non-curved walls.

  Thus, since the lower surface of the engaging portion 32 is cut while being curved, the receiving portion 40 can be used as the preceding non-curved wall renewal panel even if the length of the main body 16 in the direction perpendicular to the first end 12 is long. It can be fitted to the engaging portion 32 of the member 38a. Further, by pushing down the main body 16 with the first end 12 of the main body 16 as a fulcrum, even if the length of the main body 16 on the first end 12 side is long, the lever 42 is used to hold the locking portion 42 with a small force. It can be inserted into the recess 18 of the preceding non-curved wall rehabilitation panel member 38a. For this reason, the burden at the time of connecting the non-curved wall rehabilitation panel member 38 to the inner surface of the open channel 50 is small, and the non-curved wall rehabilitation panel member 38 can be easily connected by a human hand.

These can be connected, aligning the surface of the adjacent curved wall rehabilitation panel member 10 and the surface of the non-curved wall rehabilitation panel member 38 to be flush with each other. Further, as shown in FIG. 20, the curved wall rehabilitation panel member 10 extends along the curved wall surface portion of the open channel 50, and the non-curved wall rehabilitation panel member 38.
Connected to

  Then, the anchor 52 is inserted into the through hole 26 and driven into the bottom surface of the open channel 50 to fix the renovated panel member 10 for the curved wall surface.

  In FIG. 19, the connected second surface 22 side is shown for easy understanding of the connection state between the curved wall rehabilitation member 10 and the non-curved wall rehabilitation panel member 38. For this reason, the anchor 52 and the like are omitted.

  Even when the subsequent succeeding curved wall wall rehabilitation panel member 10a is connected, it is substantially the same as the previous curved wall wall rehabilitation panel member 10. In order to distinguish the subsequent curved wall rehabilitation panel member 10a from the preceding curved wall rehabilitation panel member 10, the subsequent curved wall rehabilitation panel member 10a is shown as 10a. Is.

  That is, the receiving portion 28 is cut so that the inclination angle of the tip 28a of the succeeding curved wall surface rehabilitation panel member 10a becomes the bending angle β of the curved wall surface portion of the open channel 50 shown in FIG. The cut end 54 is inserted into the space formed by the receiving portion 28.

  Further, similarly to the non-curved wall rehabilitation panel member 38 of FIG. 18, the far end side 18 b of the recessed portion 18 of the curved wall renovated panel member 10 fixed to the open channel 50 is cut, and the end of the recessed portion 18 is cut. The height is made equal to or greater than the height h from the first surface 20 of the subsequent curved wall surface rehabilitation panel member 10a to the lower surface of the receiving portion 28.

  Then, the engaging portion 32 of the curved wall rehabilitation panel member 10 fixed to the open channel 50 is fitted in the space formed by the receiving portion 28 of the subsequent curved wall rehabilitation panel member 10a to receive the subsequent curved wall rehabilitation panel member 10a. The lower surface of the portion 28 is brought into contact with the far end of the hollow portion 18 of the curved wall rehabilitation panel member 10. If the far end of the recessed portion 18 is lower than the height of the lower surface of the receiving portion 28, the lower surface of the receiving portion 28 of the subsequent curved wall surface renovation panel member 10 a may not hit the far end of the recessed portion 18.

  Thus, according to the bottom shape of the open channel 50, the non-curved wall rehabilitation panel member 38 or the curved wall rehabilitation panel member 10 is selected, and the inclination angle of the tip 28a of the curved wall rehabilitation panel member 10 is adjusted. Thus, by repeating the connecting operation of the non-curved wall surface renovation panel member 38 or the curved wall surface renovation panel member 10, the rehabilitation panel 58 is formed along the bottom surface shape of the open channel 50.

  Next, a plurality of non-curved wall rehabilitation panel members 38 are attached to the side surface of the open channel 50 as shown in FIG. Rehabilitation panel 60 is formed.

  Then, the non-curved wall surface haunch member 47 is disposed between the bottom rehabilitation panel 58 and the side rehabilitation panel 60 via the plate-like body 61 in the straight portion of the open channel 50. The plate-like body 61 is made of foamed rubber having water-stopping properties. The cross-sectional height of the plate-like body 61 is, for example, 10 to 15 mm, the width is 25 to 40 mm, and the width is formed larger than the thickness of the main body of the haunch member.

As shown in FIG. 22, the plate-like body 61 is disposed on the respective surfaces of the bottom-side rehabilitation panel 58 and the side-side rehabilitation panel 60, and both end faces 13 of the non-curved wall surface haunch member 47 are placed on each plate-like body 61. The plate-like body 61 is sandwiched between the non-curved wall surface haunch member 47 and the rehabilitation panels 58 and 60. Then, in the state as it is, the screw 63 is driven into the main body 16 of the rehabilitation panels 58 and 60 from the recess 18 of the non-curved wall hunch member 47 to fix the non-curved wall hunch member 47 to the rehabilitation panels 58 and 60. . Then, as shown in FIG. 23, the plate-like body 61 protruding from the first surface 20 side of the main body 16 of the non-curved wall surface haunch member 47 is cut with a cutter or the like.

  Then, similarly to the non-curved wall surface rehabilitation panel member 38 shown in FIG. 12, the main body 16 is pushed down after the engaging portion 32 of the preceding non-curved wall surface hunch member 47 is fitted in the space formed by the receiving portion 40. By pushing down, the front end 40b of the receiving portion 40 fits into the notch 34 of the preceding non-curved wall surface haunch member 47, and crushes the water stop material 36 to stop the joint. Further, the engaging portion 42 enters the inside of the hollow portion 18 of the preceding non-curved wall surface haunch member 47, and the engaging portion 44 is engaged with the engaging portion 25 of the preceding non-curved wall surface haunch member 47, so The movement of the wall surface haunch member 47 in the vertical direction and the horizontal direction is restricted, and the non-curved wall surface hunch members 47 are connected to each other. Furthermore, the hollow portion 18 of the preceding non-curved wall surface haunch member 47 is covered with the main body 16 so that the first surface 20 of the non-curved wall surface haunch member 47 is flush. Then, by repeating this, the non-curved wall surface haunch member 47 covers the space between the rehabilitation panel 58 on the bottom surface and the rehabilitation panel 60 on the side surface.

  Further, a curved wall surface haunch member 45 is used in the curved portion of the open channel 50. First, similarly to the curved wall rehabilitation panel member 10 shown in FIGS. 15 to 17, the inclination angle of the first end 12 and the distal end 28 a with respect to the second end 14 becomes the bending angle α of the curved portion of the open channel 50. Then, the first end 12 side of the main body 16 and the receiving portion 28 are cut, and the cut end 54 of the receiving portion 28 is inserted into the space defined by the receiving portion 28. Similarly to FIG. 18, the far end side 18 b of the recessed portion 18 of the preceding curved wall surface haunch member 45 or non-curved wall surface haunch member 47 is cut.

  Then, similarly to the non-curved wall surface haunch member 47 shown in FIGS. 22 and 23, the plate-like body 61 is sandwiched between the inclined end surface 13 of the curved wall surface haunch member 45 and the renovated panels 58 and 60, and then curved. A screw 63 is driven into the main body 16 of the rehabilitation panels 58 and 60 from the recess 18 of the wall surface haunch member 45.

Similar to FIG. 22, a screw 63 is driven into the main body 16 from the recess 18, and the curved wall surface haunch member 45 is fixed to the rehabilitation panels 58 and 60 via the plate-like body 61. By repeating the connecting operation of the curved wall surface haunch member 45, the curved wall surface haunch member 45 can be covered along the bottom surface shape of the open channel 50 between the rehabilitation panel 58 on the bottom surface and the rehabilitation panel 60 on the side surface. .

  Finally, as shown in FIG. 24, when a filler 64 such as mortar is injected between the side surface of the open channel 50 and the rehabilitation panel 60 on the side surface, the filler 64 is interposed between the side surface of the open channel 50 and the main body 16. Between the side surface of the open water channel 50 formed by the spacer 48 and the recess 18, and through the recess 18, it flows between the bottom surface of the open water channel 50 and the renovation panel 58, and the inner surface of the open water channel 50 and each A filler 64 is filled between the rehabilitation panels 58 and 60. At this time, the projecting portion 30 of the main body 16 is fitted into the filler 64 and exhibits a throwing effect. Therefore, the existing open channel 50 and the rehabilitation panels 58 and 60 are integrated by the filler 64. The filler 64 does not enter the space defined by the receiving portion 28. However, since the cut end 54 is fitted in this space, the strength of this portion is reinforced by the cut end 54 and non-destructive inspection is performed. A hindering cavity is not formed.

In this way, the first end 12 and the first end 12 that cover the anchor 52 attached to the recessed portion 18 on the first end 12 side of the main body 16 and that are adjacent to each other by the receiving portions 28 and 40 and the water stop material 36 in the notch 34. The joint with the two ends 14 is stopped. Thereby, the water which flows in the open channel 50 does not enter between the renovation panel 50 and the inner surface of the open channel 50 from the recess 18 through the anchor 52, and the durability of the renovated open channel 50 is maintained. . In addition, after the rehabilitation panel 50 is formed, not only the joint portion of the main body 16 but also each of the anchors 52 need not be water-stopped with a silicon sealant or the like, thereby improving the workability.

  Further, the first surfaces 20 of the adjacent main bodies 16 are flush with each other, and the heads of the anchors 52 and the like do not appear on the first surface 20, so that the appearance is excellent, and the water smoothly flows through the open channel 50. The flow velocity and flow rate are ensured.

  Further, by forming the main body 16 and the recessed portion 18 with a vinyl chloride resin, the cost of the curved wall rehabilitated panel member 10 and the non-curved wall rehabilitated panel member 38 can be reduced. Moreover, by covering the surface of the first surface 20 of the main body 16 with the acrylic resin layer 24, the deterioration of the vinyl chloride resin due to ultraviolet rays can be prevented, and the durability of the renovated open channel 50 can be ensured.

  By providing the protrusion 30 on the second surface 22 of the main body 16, the rigidity of the main body 16 can be increased and the thickness of the main body 16 can be reduced. Thereby, the material cost of the curved wall rehabilitation panel member 10 and the non-curved wall renewal panel member 38 is suppressed, and the curved wall rehabilitation panel member 10 and the non-curved wall rehabilitation panel member 38 become lighter.

For this reason, the rehabilitation panel 58 can cover the bottom surface of the curved portion of the open water channel 50, so that the water flowing through the open water channel 50 is less likely to enter between the rehabilitation panel 58 and the bottom surface of the open water channel 50. The strength of the open channel 50 is maintained.

  Then, by forming the width of the receiving portion 28 longer than the width of the engaging portion 32, the width of the receiving portion 28 is engaged even when the tip of the receiving portion 28 is cut to a desired bending angle within a certain range. Since it can remain longer than the width of the portion 32, the receiving portion 28 can be fitted into the adjacent engaging portion 32. Thereby, since the receiving part 28 is latched by the engaging part 32, the curved wall rehabilitation panel member 10 can be easily joined to the non-curved wall rehabilitation panel member 38 or the curved wall rehabilitation panel member 10. .
