  As shown in FIG. 7, the cap member 40 is a rectangular plate-like body formed of a synthetic resin such as hard vinyl chloride, and the first end 24 of the panel member 22 and the first of the other adjacent panel members 22. It is a member that covers the recess 30 after connecting the two ends 26.

  The length of the cap member 40 in the longitudinal direction is equal to the first end 24 and the second end 26 of the panel member 22 and is set to, for example, 300 mm, and the shorter length corresponds to the width of the recess portion 30. It is set so as to cover the entire part 30. For example, the surface of the cap member 40 is coated with a weather resistant resin such as an acrylic resin. Further, the surface of the cap member 40 is flat, and when the cap member 40 covers the recess 30, the surface of the cap member 40 is flush with the first surface 32 of the panel member 22 to form the surface of the renovated panel (see FIG. 1).

  With reference to FIGS. 8 to 14, a method of rehabilitating the bottom surface and the side surface of the open water channel 100 as shown in FIG. 8 with the rehabilitation panel using the corner member 10 of this embodiment will be described below.

  First, water is dammed in advance with a concrete panel or the like upstream from the construction part of the open channel 100, and the water dammed up by a submersible pump or the like is discharged downstream from the construction part. Then, mud and the like on the bottom and side surfaces of the open channel 100 are removed with a high pressure washer or the like, and particularly the protruding portion is removed with a disk sander or the like.

  Then, a plurality of panel members 22 for forming the rehabilitation panel and a panel fixture 42 such as an anchor for fixing the panel member 22 to each of the bottom surface and the side surface of the open channel 100 are prepared.

  Next, the second surface 34 of the panel member 22 is directed toward the bottom surface side of the open channel 100, and the first end 24 and the second end 26 are perpendicular to the longitudinal direction of the open channel 100, so that the panel member 22. Is disposed on the bottom surface of the open channel 100, the panel fixture 42 is inserted into the through hole 38, and driven into the bottom surface of the open channel 100. At this time, as shown in FIG. 9, a spacer 44 for preventing the panel member 22 from being bent is appropriately attached to the panel fixture 42. Thereby, the panel member 22 is fixed at a distance from the bottom surface of the open channel 100 by the panel fixing tool 42 attached to the through hole 38.

  Then, the next panel member 22 is disposed at the first end 24 of the fixed panel member 22, and the next panel member 22 is adjacent to the first end 24 without being fixed to the open channel 100 by the panel fixture 42. The second end 26 of the panel member 22 to be joined is joined. As a result, the adjacent panel members 22 are connected to each other, and the next panel member 22 is not fixed to the open channel 100 by the panel fixture 42 in the same manner as the previous panel member 22, and the first end 24. And the second end 26 of the adjacent panel member 22 are joined.

  Instead of fixing all the panel members 22 to the open channel 100 with the panel fixtures 42, for example, it is preferable that each of the three panel members 22 is fixed to the open channel 100 with the panel fixtures 42. . Further, in the panel member 22 to be fixed, the panel fixtures 42 are not attached to all the through holes 38. For example, if five through holes 38 are formed, the three through holes 38 are provided with the panel. A degree to which the fixing tool 42 is attached is preferable.

  As described above, the connection between the panel members 22 is repeated, and the bottom surface of the open channel 100 is covered with the panel member 22 as shown in FIG. 10, and the first renovated panel 102 is formed on the bottom surface of the open channel 100.

  Subsequently, the side surface of the open water channel 100 is covered with the panel member 22 in the same manner as the first renovated panel 102, and the second renovated panel 104 is formed on the side surface of the open water channel 100.

  Next, as shown in FIG. 11, the corner member 10 is arranged at the joint between the first renovation panel 102 and the second renovation panel 104 in the corner portion of the open channel 100. However, the corner member 10 may be disposed after the first rehabilitation panel 102 is provided and before the second rehabilitation panel 104 is provided.

  Specifically, in a state where the seal part 20 of the second part 16 is brought into contact with the first surface 32 of the panel member 22 forming the second rehabilitation panel 104, the first rehabilitation panel 102 and the second rehabilitation panel 104 The locking portion 18 is inserted into the seam. Then, the locking portion 18 is locked to the side surface of the first renovated panel 102, and the seal portion 20 of the first portion 14 is brought into contact with the first surface 32 of the panel member 22.

  Then, the supports 46 and 52 and the support fixture 48 are prepared. The supports 46 and 52 are long members, and for example, steel pipes such as round pipes are used. The support fixture 48 supports and fixes the support 46 at a fixed height, and a pipe clamp or the like is used.

  Then, as shown in FIG. 12, the support work 46 is passed over these panels across the adjacent panel members 22, and the support work fixing tool 48 is attached to the through hole 38.

  Specifically, as shown in FIG. 13, first, the support fixture 48 is screwed into the anchor 50 that has been driven into the bottom surface of the open channel 100 in advance, and the support fixture 48 is fixed. Then, the support 46 is attached to the support fixture 48, and the height of the support 46 is adjusted so as to be parallel to the bottom surface of the open channel 100 or to have a constant gradient according to the application. The support work 46 is fixed by a fixing tool 48.

  However, in the panel member 22 that covers the side surface of the open channel 100, that is, the second rehabilitation panel 104, first, a plurality of support works 52 that are long in the longitudinal direction of the open channel 100 are arranged and orthogonal to the support works 52. The support 46 arranged in this manner is fixed by a support fixture 48 (see FIG. 12). In this case, as shown in FIG. 14, the support work 52 is also arranged on the surface 12 a of the main body 12 of the corner member 10, and the first part 14 is placed on the first renovated panel 102 and the second part. 16 is pressed on the second rehabilitation panel 104.

  As a result, the support 46 is fixed to the bottom and side surfaces of the open channel 100 by the support fixture 48, and the panel member 22 is held at a predetermined height by the supports 46 and 52. Further, the corner members 10 are fixedly arranged at the joint between the first renovation panel 102 and the second renovation panel 104 by the supporters 46 and 52.

  The support fixture 48 is preferably attached not to the panel member 22 to which the panel fixture 42 is attached, but to the through hole 38 of the panel member 22 connected to the panel member 22.

  Next, between the connected panel member 22 and the bottom surface and side surface of the open channel 100 in a state where the support members 46 and 52 prevent the panel member 22 from rising from the bottom surface or side surface of the open channel 100 to a predetermined height. The backfilling material is filled in, and after the entire backfilling material is filled, it is cured.

  At this time, even if a force in the direction of lifting is applied to the panel member 22 due to the filling pressure of the backfilling filler, the panel member 22 is restrained from moving in the direction of lifting by the panel fixing device 42 and the supporters 46 and 52. Therefore, it is held at a predetermined height. Further, the corner member 10 is also prevented from being detached from the rehabilitation panels 102 and 104 because the movement in the direction of lifting by the supporters 46 and 52 is suppressed.

  Then, when the backfilling material is solidified to some extent, the supporters 46 and 52 are removed from the supporter fixture 48, and the supporter fixture 48 is further removed from the open channel 100. However, only the anchor 50 of the support fixture 48 may be left in the open channel 100.

  And in the adjacent panel member 22, since the 1st hollow part 30a and the 2nd hollow part 30b adjacent are connected and the U-shaped hollow part 30 is formed, it covers with the cap member 40. As a result, the first surface 32 is flush with the surface of the cap member 40, a rehabilitation panel is formed, and the bottom and side surfaces of the open channel 100 are rehabilitated with the rehabilitation panel (see FIG. 1).

  According to this embodiment, the seal part 20 in the first part 14 of the corner member 10 is brought into contact with the first renovation panel 102, and the seal part 20 in the second part 16 is brought into contact with the second renovation panel 104. Thus, the joint between the first retreaded panel 102 and the second retreaded panel 104 can be hermetically and watertightly closed. Further, by pressing the surface 12a of the main body 12 of the corner member 10 by the support 46, the first part 14 can be pressed to the first renovation panel 102 and the second part 16 can be pressed to the second rehabilitation panel 104. The corner member 10 is not lifted by the filling pressure or the like when the backfilling material is placed. For this reason, the water stop process by a sealing material etc. is unnecessary for the joint of the 1st renovation panel 102 and the 2nd renovation panel 104 after placement of a backfilling filler. Therefore, it is excellent in workability.

  Furthermore, since the sealing material is inferior to weathering as compared with the rehabilitation panel, for example, if a water-stopping treatment with a sealing material is applied to the joint between the first rehabilitation panel 102 and the second rehabilitation panel 104, Only the joint with the second rehabilitation panel 104 needs to be frequently maintained. On the other hand, according to this embodiment, the frequency of maintenance is suppressed.

  In addition, if the corner member 10 can bring the seal portion 20 in the first portion 14 into contact with the first renovated panel 102 and the seal portion in the second portion 16 can come into contact with the second renovated panel 104, the panel member Regardless of the shape of 22, the joint between the first retreaded panel 102 and the second retreaded panel 104 can be hermetically and watertightly closed. For this reason, it is not necessary to prepare the corner member 10 matched with the shape of the panel member 22, and by giving the corner member 10 versatility, it leads to reduction of the kind of product, the amount of inventory, and the production efficiency. Excellent economy.

  Further, a locking portion 18 is provided on the back surface of the main body 12 of the corner member 10. The locking part 18 can position the corner member 10 at a fixed position by locking to the side surface of the first renovation panel 102. Thereby, the surface 12a of the main body 12 can be pressed down easily and smoothly by the supports 46 and 52.

  Furthermore, according to this embodiment, since the main body 12 of the corner member 10 is formed of a flexible synthetic resin, the angle formed by the first portion 14 and the second portion 16 can be changed. Therefore, not only the joint between the first renovation panel 102 provided on the bottom surface of the open water channel 100 as shown in FIG. 8 and the second renovation panel 104 provided on the side surface, but also in the entrance corner as shown in FIG. Also in the open water channel 106 in which is formed, the joint between the first renovation panel 102 provided on the bottom surface of the open water channel 106 and the third renovation panel 108 provided on the haunch portion, and the third renovation panel 108 and the open water channel 106. The joints with the second rehabilitation panel 104 provided on the side surfaces can be respectively closed by the corner members 10.

  Here, referring to FIG. 16, a method of closing the joint between the first retreaded panel 102 and the third retreaded panel 108 and the joint between the third retreaded panel 108 and the second retreaded panel 104 by the corner member 10 will be described below.

The joint between the third renovation panel 108 and the second renovation panel 104 provided on the side surface of the open water channel 106 can also be closed by the corner member 10.

  A corner member 10 which is another embodiment of the present invention shown in FIG. 28 is different in the shape of the corner member 10 and the main body 12 in the embodiment of FIG. Hereinafter, detailed description of the same parts as those of the corner member 10 in the embodiment of FIG. 1 will be omitted.

  The corner member 10 includes a main body 12 including a first portion 14 and a second portion 16.

  The first portion 14 is formed in a rectangular plate shape, and a locking portion 18 for locking to the side surface of the first renovation panel 102 is integrally formed at one end portion thereof. The locking portions 18 are each formed in a plate shape that protrudes from the back surface of the first portion 14 in a direction orthogonal to the first portion 14.

  The second portion 16 is formed in a plate shape that protrudes obliquely upward from one end portion of the first portion 14 on the side where the locking portion 18 is formed.

  A locking portion 64 for locking to the side surface and the back surface of the second rehabilitation panel 104 is integrally formed at one end portion of the second portion 16 on the first portion 14 side. The locking portion 64 protrudes from the end of the second portion 16 in a direction orthogonal to the second portion 16, and the tip portion further protrudes in a direction parallel to the second portion 16, and the cross section is substantially L-shaped.

The first seal portion 20 a is formed in a protruding shape that slightly protrudes from the back surface of the first portion 14. The second seal portion 20 b is formed on the bottom of the concave shape formed by the receiving portion 66.

  When such a corner member 10 is arranged at the joint between the first renovated panel 102 and the second renovated panel 104, as shown in FIG. The first seal portion 20a of the first portion 14 and the first surface 32 of the first renovation panel 102 are brought into contact with each other by being engaged with the side surface. And the lower end part of the 2nd renovation panel 104 is covered with the receiving part 66, and the lower end of the 2nd renovation panel 104 and the 2nd seal part 20b are made to contact | abut. For this reason, the corner member 10 in this embodiment is preferably disposed after the first rehabilitation panel 102 is provided and before the second rehabilitation panel 104 is provided. Then, the support work 52 is arranged on the surface 12a of the main body 12 of the corner member 10, and the first part 14 is attached to the first renovation panel 102 by the support work 46 and the support fixture 48 (not shown), and The second part 16 is pressed against the second rehabilitation panel 104.

  The other steps are the same as those in the embodiment of FIG.

  Thus, in this embodiment, the lower end portion of the second renovation panel 104 is covered by the receiving portion 66 of the corner member 10. For this reason, even if a force in the direction of lifting is applied to the panel member 22 due to the filling pressure of the backfilling filler or the like, the back side of the second rehabilitation panel 104 and the locking portion 64 are locked, so that the corner member 10 is lifted. Movement in the direction is suppressed. Therefore, even if the main body 12 cannot be pressed and fixed to the rehabilitation panels 102 and 104 by the supporters 46 and 52, the corner member 10 is attached to the rehabilitation panels 102 and 104 when the backfill filler is placed. I will not deviate from.

  In each of the above-described embodiments, a steel pipe such as a round pipe is used as the support works 46 and 52. However, the present invention is not limited to this.

However, the present invention is not limited to this. For example, the main body 12 of the corner member 10 is formed of a synthetic resin having weather resistance, or the main body 12 of the corner member 10 is formed of synthetic resin mixed with a weather resistant resin. Equivalent weather resistance can also be ensured on the surface 12a of 12 and the surface of each renovated panel 102,104.

  Further, in each of the above-described embodiments, a plurality of support works 52 that are long in the longitudinal direction of the open water channels 100 and 108 are arranged, and another support work 46 arranged so as to be orthogonal to the support works 52 is used for the support work. Although the surface 12a of the main body 12 of the corner member 10 is pressed and fixed by fixing with the fixing tool 48, it is not necessary to be limited to this. For example, the surface 12a of the main body 12 of the corner member 10 is directly pressed and fixed by the support 46 that is long in the width direction of the open channels 100 and 108 without using the support 46 and the support 52 doubly.
