Key Construction Techniques For Chongqing PengXiHe Bridge

Because Cable-stayed bridge with a span capacity, structure performance, architectural modeling beauty, fewer restrictions on construction, investment costs provincial, and many other features, so it suitable for the construction of the river width, depth, poor geological conditions, construction face small and higher shipping requirements place under the bridge.PengxiHe River in the western mountains as a cable-stayed bridge of Yunyang to Wanzhou, Chongqing Expressway to the Contract Section I, because of its unique geological conditions, influenced by the water, tower height and narrow space features, in order to be more targeted of resolving issues related to the construction, therefore research its key technologies is essential.This paper comprehensive summary the key construction technologies of the Peng River cable-stayed bridge,to provide a reference for the role and reference value of the western mountain cable-stayed bridge construction techniques.The article is divided into the following five parts:1,A brief description of the cable-stayed bridge the generation,development and outlook, and explains the purpose and significance of this study and the main working content.2,The background project of Peng River Bridge made an introductory general situation of the project, including the bridge's overall layout, structural design, meteorology, hydrology, engineering geology and so on.3,This paper focuses introduced the construction technology of bored pile on high-intensity rock mountain bridge4,This paper focuses introduced the useing of the hydraulic climbing formwork of the large cross-section in the main pier and the pier in ultra-high tower.5,This paper focuses introduced the construction technique for integral lifting of large anterior form travelers of cable-stayed bridge and suspension poured double side-boxes girder by large anterior form travelers.
