Abstract

With the decrease of bridge site resources, double-deck frame bridges are more and more used in bridge construction. In order to solve the problem that the conventional movable scaffolding system is difficult to through the hole of the frame pier, a new type of split movable scaffolding system suitable for the double-deck frame bridge is developed in this paper based on the approach bridge of Maanshan Yangtze River Rail-cum-Road Bridge. A coupling analysis method of double-deck frame bridge structure-multi-leg movable scaffolding system based on iterative method is proposed, and the field preloading verification test is carried out. The results show that the new type of split movable scaffolding system with separated design and split support of flange formwork and bottom formwork can realize split through-hole and reset casting, which can effectively realize split through-hole of the frame pier and fast clamping casting, and provide a new idea for the construction of similar double-deck frame bridge. The test values of the preloading test are in good agreement with the simulated values, which indicates that the proposed iterative method can effectively simulate the coupling effect of double-deck frame bridge and multi-legged movable scaffolding system. The maximum deformation of the railway beam at the support leg of the movable scaffolding system is up to 21mm, which shows that the influence of the coupling effect of the structure and the formwork on the alignment of the upper highway beam cannot be ignored.
