Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a steel box girder temporary manhole loading and unloading equipment, an installation method and a disassembly method. Background technique [0002] Steel box girder is a common structural form of long-span bridges, and is generally used on bridges with large spans. Temporary manholes must be opened for the construction personnel to enter and exit during the welding operation of the steel box girder of the viaduct. [0003] At present, the traditional method is usually used to open the manhole. The opening method is to weld two or three knife handles at the position where the manhole is opened, and use the knife handle as a support point to lift the temporary manhole manually. This method requires the cooperation of multiple people, making the construction Slower and less efficient. When closing the temporary manhole, it is also necessary to manually lift the temp...
