Analysis of Intelligent Tensioning Construction Technology for Precast Concrete Continuous Beams in Expressway Engineering
In order to improve the efficiency and quality of expressway construction,the intelligent prestressing and tensioning construction technology of precast concrete continuous beams was studied.Position the prestressed steel bars on the selected expressway bridge project and install steel strands,while calculating the elongation of the steel strands and setting the tension parameters based on the calculation results;A prestressed intelligent tensioning system was conducted,within which the tensioning equipment was controlled,to achieve synchronous ten-sioning of multiple jacks,and thus complete the construction of continuous beam prestressed tensioning.Experimen-tal analysis shows that compared to traditional manual tensioning methods,and this intelligent tensioning technol-ogy can effectively reduce the deviation of elongation during the tensioning process.
