Design and Construction Technology of Assembled Ladder Cage Platform with Cylindrical Piers
The safety ladder and pier top platform used in the construction of conventional bridge cylindrical pier are complicated,and their safety is relatively poor.In order to solve the above problems,a kind of prefabricated ladder cage platform with cylindrical pier is proposed,which integrates the personnel passageway and the construction platform,and assemble-type installation,simplifying the construction process.Because the height to width ratio of the assembled ladder cage is reduced,its own stability is optimized,and wall attachment or cable wind rope can be eliminated,which is safer and more convenient than the traditional safety ladder.The results show that the cylindrical pier prefabricated ladder cage construction platform is successfully applied to Meishan Viaduct and Meishan inter-working,which truly realizes the function integration.All the components of the platform are processed in the factory and assembled on site,so as to achieve the purpose of factory production and construction assembly,and the construction convenience is significantly im-proved.
