Research on the Application of Construction Technology for the Main Tower Bearing Platform of Highway Bridge
Based on the construction example of a bridge project in Tongnan,this paper expounds the construction process flow and key construction technical points of the main tower bearing platform of highway bridge,mainly including steel cofferdam processing,hoisting,positioning and sinking,bottom sealing,bearing platform and binder construction,etc.The main tower bearing platform and binder are constructed by double circular double-wall steel cofferdam,which meets the various construction technical requirements under the condition of water flow impact,reduces the construction risks and saves the project investment.It can provide some reference for the construction of main tower bearing platform of highway bridge under similar conditions.
