温州大门大桥索道管定位方法

Positioning Method of Cable Wenzhou Gate Bridge Pipe

温州市大门大桥是国内首座在设计时同步综合考虑高压输电线路、大直径输水管线过桥方案的海上特大桥,主桥为双塔双索面PC梁斜拉桥,海中主塔最大高度达136米,本桥施工精度要求高,要控制好主塔索道管的位置,有一定的难度。结合本桥的工程概况及特点,介绍了大桥的索道管施工测量方法。

Wenzhou city gate bridge is the first domestic synchronousconsidering the high voltage transmission line,the large diameter water pipelines crossing sea bridge project in the design,the main bridge of the Twin Towers and double cable plane cable-stayed bridge PC beam,the sea tower a ximum height of 136 meters,the bridge construction accuracy high,control cable the position of the tube,there is a certain degree of difficulty.Combined with the general situation of the bridgeengineering and characteristics,introduces the construction method of measuring bridge cable duct.
