Research on Construction Technology of Non Disposable Pouring Five Span Prestressed Concrete Continuous Rigid Frame Bridge

This paper relies on a project construction of prestressed continuous rigid frame bridge span highway20m+3 * 24m+20m5,according to the construction environment of the bridge near the village,the residents livinginterference characteristics,in the construction process,optimization of the continuous rigid frame bridge construction technology,5 span prestressed concrete continuous rigid frame bridge with non synchronous construction,one-off concreting,construction mode of cooperation composite scaffold erection of the door,under the premise of ensuringthe construction quality and safety,speed up the pace of construction,to ensure the normal traffic of highway,this paper mainly introduces the characteristics of bridge construction project,one-time pouring five span non prestressed continuous rigid frame of the key construction technology.
