Abstract
According to the structure characteristics, the construction quality and die work schedule of Qilihe Canal Inverted Siphon located in Xingtai City of the South-to-North Water Transfer Project, a roof formwork trolley for the construction of the inverted siphon is designed and the structural features, function principle and construction technology of the trolley are describedherein in detail. Furthermore, the calculation on the strength and stiffness of the main beam-a non-standardized key part ismade and the strength and safety of the steel pipe for railway is analyzed with the finite element method. Moreover, through a comparative analysis made with the conventional combined steel formwork and tunnel formwork trolley, a conclusion is obtained that better construction quality and comprehensive benefit can be got with the roof formwork trolley for construction of inverted siphon presented hereia关键词
