Method for constructing steel-concrete composite segment of bridge

The invention relates to a method for constructing a steel-concrete composite segment of a bridge. The method comprises the following steps of: S1, measuring the distance between composite segments; S2, erecting a reinforcement cage; S3, assembling a mold; S4, assembling a bottom supporting device; S5, casting concrete; S6, assembling a cable bent tower; and S7, treating the surface of the composite segment. According to the method for constructing the steel-concrete composite segment of a bridge, the distance between two composite segments can be measured by a laser measurement mode, the measurement result is relatively accurate, and the casting layer and the composite segment are restrained by force by adding the reinforcement length of the cage, so that the bridge has a relatively strong integrality.
