Research on the Open Caisson Positioning Plan and Innovation Technology for 6#Pier of the Main Channel Bridge of Changtai Yangtze River Bridge
The 6#pier of the main channel bridge of Changtai Yangtze River Bridge adopts the super-large stepped steel open caisson foundation.In order to solve the problem of rapid positioning and precise landing of the super-large steel open caisson,the open caisson positioning system innovatively adopts the combination of"anchor pier+high holding power anchor".The whole positioning system is composed of anchor pier,high holding power anchor,large-diameter steel rope,hydraulic continuous jack and intelligent tensioning control system.The side anchor adopts high holding power anchor,and the high holding power anchor anti-moving technology and cable fast installation technology are applied.
