Key Technology On Construction Of Huang Fang River Prestressed Concrete Continuous Girder Bridge

Along with the advance of human civilization, science and technology of rapid leap, transportation industry in China has been moving towards a new height on the river and even the gulf bridge has become increasingly common. In the face of economic development, improving the efficiency of transportation and other factors to promote the development of prestressed concrete continuous girder bridge. At present, domestic, outside the continuous girder bridge with cantilever pouring construction method. In order to ensure the strength, stiffness and durability of the bridge meet the specification requirements, to ensure the quality of continuous beam is able to achieve the desired project, the whole bridge construction monitoring, 0 # block of bracket design, calculation of hanging basket is must be considered.Paper illustrates the general method of the prestressed concrete continuous box girder construction, from the angle of design, huang fang creek 3 # bridge is analyzed in detail. Paper describes the present situation of bridge, the design adopts the technical standards, technical conditions, main material, the key points of box girder structure design, construction, etc. Through the analysis of the design, to provide the basis for the establishment of construction scheme. Through practical engineering problems, paper study the key technology of continuous beam construction and put forward reasonable solution. To provide a good reference for similar engineering construction technology.Finally, through the analysis of the whole construction process, put forward some own experiece.
