Continuous beam structure provided with V-shaped webs and construction method of continuous beam structure

The invention discloses a continuous beam structure provided with V-shaped webs and a construction method of the continuous beam structure. The continuous beam structure provided with the V-shaped webs comprises a bridge lower part support system and a combination box beam erected on the bridge lower part support system, wherein the combination box beam comprises a top plate, a bottom plate located below the top plate as well as a left V-shaped web and a right V-shaped web which are symmetrically connected between the top plate and the bottom plate; the top plate and the bottom plate are concrete slabs formed by casting UHPC (ultra-high performance concrete), each V-shaped web comprises a plurality of V-shaped precast slabs and is arranged in the longitudinal bridge direction, and the V-shaped precast slabs are V-shaped precast concrete slabs formed by casting UHPC. The construction method comprises the following steps: 1, constructing the bridge lower part support system and prefabricating the V-shaped preca
