AI Technical Summary
Technical Problem
Large-tonnage crawler cranes will block the water steel trench during construction on the water steel trench, affecting the normal operation of other construction projects.
Method used
The removable steel platform and a crawler crane with a tonnage of 40-70 tons are used. The steel platform is used as a bearing platform for transport parts on the pile foundation to achieve lifting and paving of prefabricated panels, thereby reducing the occupation of water steel trests.
Benefits of technology
Small tonnage transport parts reduce the area and pressure occupying the water steel trest, ensure the smooth passage and load bearing stability of the water steel trest, and improve the paving efficiency of prefabricated panels.

Abstract
The present application relates to a construction method for hoisting and laying prefabricated bridge panels on a detachable steel platform, and relates to the technical field of bridge construction. The construction method includes the following construction steps: building a steel platform: hoisting at least two steel platforms to be placed on a pile foundation; assembling adjacent steel platforms for standby; paving prefabricated panels: hoisting transport parts to be placed on the steel platform, and hoisting prefabricated panels through the transport parts to be laid on the pile foundation; progressive paving: disassembling the steel platform on one side of the paved prefabricated panels, and then assembling the disassembled steel platform on the other side of the undisassembled steel platform, so that the transport parts can be displaced on the adjacent pile foundation and the prefabricated panels can be laid; finishing paving: hoisting the prefabricated panels to be laid on the pile foundation, so that the area at the top of the pile foundation and between the steel trestle on the water and the prefabricated panels that have been laid is completed. The present application has the effect of reducing the blockage of the steel trestle on the water and ensuring the paving efficiency of the prefabricated panels on the pile foundation.
