| Existing railway bridge construction site management methods have problems such as low degree of informationization and extensive management methods.For railway bridge projects with complex environments,narrow sites,and tight schedules,improper construction management can lead to unnecessary time consumption,capital waste,and increase in labor and equipment,which will ultimately affect the results,which is cost consumption and schedule delay Rear.By studying the characteristics and modes of information transmission on the railway bridge construction site,in order to strengthen the connection between the virtual model and the construction site.This paper selects the two-way coordination mode of virtual model and construction site information as the research point,compares traditional management methods with lean management methods,summarizes the advantages of lean management in railway bridge construction sites,and proposes a railway based on BIM and construction simulation Lean management method for bridge construction site.This method uses BIM technology to create building models and site layout models that contain complete railway bridge engineering information,conduct collision inspection,space inspection and engineering quantity statistics;import the model into the BIM-film virtual construction software,and simulate the bridge construction site in combination with the construction schedule.Real-time dynamics,including mechanical transportation,material stacking and operation beats,realize the combination of virtual construction animation and schedule planning.According to site changes,predict possible problems,adjust the simulation process in real time,and present dynamic visual construction management.Practice has proved that the proposed method can optimize the on-site management process,shorten the transportation and storage cycle,reduce the inventory backlog,and reduce the loss and waste of materials.Prejudge model conflict points and modify them in real time to ensure construction quality and structural safety performance;quantify the quantity of materials,formulate accurate tasks for suppliers and mechanical equipment,avoid waste of materials,mechanical equipment and labor;select appropriate mechanical configuration,Optimize transportation routes and mechanical operating parameters to improve transportation,loading and unloading,and operation efficiency;real-time tracking of materials,real-time acquisition and modification of component information through QR codes.Realize the online rectification of quality and safety issues at the construction site,carry out dynamic and traceable management of the whole life cycle of team personnel,materials,and mechanical equipment,and realize the informationization of quality and safety management. |
