The utility model belongs to the technical field of building engineering, particularly, involve a bridge drip structure. Bridge drip structure includes that drip, building structure glue and cement nail, the proximal end portion at the limit of bridge flange board lower edge is installed to the drip, the circular arc both sides of drip are passed through building structure glue and are fixed on the flange board of limit, cement nail follows closely into to limit flange inboard from the outside of the circular arc of drip central authorities. Compared with the prior art, set up at newly -built bridge boundary beam bridge drip structure can guarantee effectively that the form removal in -process does not produce the piece at edge of a wing tip, and rain erosion can not suffered to the roof beam behind the bridge builds up, guarantees that bridge concrete durability and boundary beam outward appearance are neat and artistic, set up this bridge drip structure at the bridge of operation that does not set up the drip and can effectively avoid the rainwater to continue to cause the erosion to the bridge boundary beam, guarantee that bridge concrete durability and boundary beam outward appearance are neat and artistic.
