Disclosed is a construction method for installing an open sewer bridge which provides a duel structure, which has a waterproof function, on the inner surface of a connection unit between open sewers and inside the connection unit, and which can correspond to the contraction and expansion of the open sewers. The construction method for installing an open sewer bridge according to the present invention comprises: a step for forming a block-out to expose an internal reinforcing bar by digging the inside of one end of each of the open sewers to be connected to each other; a step for connecting an anchor to the reinforcing bar exposed on the inner side of the open sewer; a step for attaching waterproof materials to the ends of the open sewers to be connected to each other; a step for curing mortar after injecting the mortar into the block-out; and a step for fastening a nut to the exposed anchor by coating a resin adhesive on the inner surface of the mortar of the connection unit, bonding the expansion waterproof material, which has a steel sheet built therein, and then making the protruded anchor penetrate the inner surface of the mortar, wherein the open sewer bridges are connected with each other on the connection unit. |
