At present,the number of welds in railway engineering technology improvement and renovation projects is relatively small.When using flash welding to weld steel rails,there are differences between the budget prepared directly using the current railway engineering quota system and the actual costs incurred during the construction process.In response to this issue,this article conducts a systematic analysis of the supporting quotas for welded steel rails under the current quota system in conjunction with a high-speed railway signal equipment renovation project.The following conclusion is drawn:in the technical renovation project,the number of welds is relatively small,and there are differences between the labor and machine shift consumption in the flash welding quota and the actual situation,resulting in insufficient consideration of engineering costs and inspection costs such as type inspection.During the design process,the consumption of flash welding quotas can be re measured,and appropriate adjustments can be made to the labor and shift consumption in the quotas or supplementary unit price analysis can be used.
