Research On Construction Safety Technology Of The Concrete Filled Steel Tube Arch Bridge

The CFST arch bridge construction control and monitoring technology is the most important part of Bridge construction. The main task of this technique is to detect and control the whole process of the construction of CFST arch bridge, so as to ensure the safety of bridge construction and stable structure, which makes the bridge stress and deformation controlled in the safe range and the design of the bridge meet the specification requirements.In recent years, the construction of transportation infrastructure is particularly important, which provides an important guarantee for the construction of large span concrete filled steel tube arch bridge. The advantages of steel pipe concrete construction can provide reliable guarantee. At present, most of the construction of CFST arch bridge uses no bracket cable-stayed suspension, which is the arch rib assembled under the bridge, and the whole hoisting system.In this paper the engineering is first introduced based on the cross of Beijing Hangzhou canal construction of CFST arch bridge, and the detailed introduction of the main bridge superstructure construction technology scheme is followed, finally the cross of Beijing Hangzhou canal concrete filled steel tube arch bridge construction safety measures are carried out in detail.
