。(Conventional technology and its problems) Conventionally, as a method for repairing existing waterways, etc., the so-called concrete replacement method has been common, in which defective parts of existing concrete are removed and new concrete is poured. This construction method requires work such as chipping out defective parts of existing concrete, removing it, and pouring new concrete, which has the disadvantage of a long construction period. As a result, for example, in the case of a waterway at a hydroelectric power plant, the period of water outage becomes long, and the loss of energy during that period becomes significant.
（発明の目的）
本発明は、かかる従来例の欠点に鑑みてなされたもので

るものである。(Function) A fixing member (2) is installed on the inner surface of the existing waterway (^), an FRP board (1) is stretched over the fixing member (2), and then,
Since cement milk (3) is poured between the inner surface of the existing waterway (^) and the FRP board (1), the construction period is significantly shortened compared to the conventional concrete replacement method.
In addition, it is possible to use a large amount of factory products with excellent quality control, such as fixing members (2) and FRP plates (1), making it possible to create a highly reliable structure.
By pouring cement milk (3) between the P board (1), it is possible to repair defective parts of the existing concrete (cracks, etc.), and furthermore, the existing concrete surface can be replaced with the FRP board (1). Since it is protected by a cement layer, it is possible to suppress the progress of carbonation of the existing concrete.

好ましい性質を有している。The targets of repair are various existing concrete waterways, such as waterways at hydroelectric power plants and underdrains (B). The FRP board (1) to be stretched over the inner surface of the existing waterway (8) is a composite board made of thermosetting resin reinforced with fibers, and in this case, a board with no irregularities on the surface is mainly used. (As a general rule, use only one surface with unevenness, and use the smooth side as the surface that will be in contact with running water.) The type of FRP board (1) does not matter, but in this example, resin mortar as shown in Figure 8 is used. A composite FRP board with FRP layers laminated on both sides of the layer is used. The resin mortar layer is an integrated mixture of silica sand and resin, and has a compressive strength of 1,200 to 1.3.
00kg/Cm2, which is extremely large and has desirable properties as a waterway repair material.

レート（１０）を配設する。First, a blind hole (4) is drilled into the inner surface of the existing waterway (^), and after cleaning the blind hole (4), adhesive (5
) (for example, an adhesive such as the trade name Chemical Anchor), drive the anchor bolt (2a) into the blind hole (4), and tighten the anchor bolt (2a) into the blind hole (4) with adhesive (5).
Next, attach the lip type steel (2b) along the waterway to the anchor bolt (2a) (6).
Screw it on. The FRP board fixing hardware (in the example shown in the figure, the lip type* (2b), etc.) has a screw hole screwed into it. Stretch the FRP board (1). For the corner part, as shown in Figure 5, cut-out long pieces (7) are attached to the protruding corners of the FRP board (1) with blind rivets (8) and countersunk bolts ( 9
). In addition, as shown in FIG. 2, an adjustment plate (10) is provided between the inner surface of the existing waterway (^) and the lip-shaped steel (2b), if necessary.

る。In the case of a dark hole (B), use the lip type steel (2C) for the corner of the dark hole (B) as shown in Figure 6, and attach the F of the ceiling part.
The RP board (1a) is stretched. Lip type steel for corners (
2c) is a tongue piece that matches the angle of the ceiling as shown in Figure 7.
11) is welded to the lip type steel (2b),
A ceiling FRP board (1a) is screwed onto this tongue piece (11).
