Summary:PROBLEM TO BE SOLVED: To maintain a concrete open channel exhibiting satisfactory water-tightness over a long time. SOLUTION: The joint repairing structure 10 is used for repairing the joint 102 of the concrete open channel 100 and includes an adhesive layer and a joint material layer 14. The adhesive layer is used to enhance the adhesion strength between the joint material layer 14 and concrete open channel 100, and includes a first adhesion layer 12a and a second adhesion layer 12b spaced at a prescribed interval from each other. The first and second adhesive layers 12a, 12b are respectively formed on both sides in the width direction of a filler 104 filled in the joints 102, and the space between the first and second adhesive layers makes a non-adhesive layer 16 without primer coated. The joint material layer 14 comprises, for example, an elastic resin material having elasticity and flexibility, and is formed on the first and second adhesive layers 12a, 12b. The joint material layer 14 is formed on the range across the first and second adhesive layers 12a, 12b, covering the entire outer face of the filler 104. COPYRIGHT: (C)2011,JPO&INPIT
