Research On High-angle Swing-Method Construction Technology Of Continuous Girder Cross Existing Qingdao-Jinan Railway Passenger Dedicated Line

Nowadays, the scale of railway construction in our country is increasingly expanding, especially High-speed Rail building steadily, the line interchanges are more and more frequent, on both the influence degree of traffic line minimum rotation construction method gradually appeared in the field of railway construction. Some domestic railway railway construction across existing roads, railway began to use this technique. At present, construction features mostly with swivel span, large weight, rotary table and ball ream. For small span, small diameter turntable and a spherical hinge swivel bridge, less engineering examples. Therefore, in this paper, combined with the new railway engineering project Qingdao-Jinan Railway passenger dedicated Line across Haitian-Qingdao Railway bridge, with small span continuous beam, small diameter turntable and a ball hinge, and cross the busy Qingdao-Jinan Railway passenger dedicated Line, the research of "continuous beam cross Qingdao-Jinan Railway passenger dedicated Line rotation construction technology" the main technique, key process before and after the implementation of the relevant data, swivel construction process monitoring, rational arrangement and construction process control and safety technical measures etc.. Mainly studied the principle of upper and lower structure, swivel swivel arrangement, calculation of force, the spherical hinge plane radius, flat turn important parameters of traction force, traction force, thrust rotation and twist time ball hinge vertical, ball hinge, traction cable parameter, Jack Twist the core components of the calculation and selection, construction technology the turntable, turntable, ball hinge, slide, the counterforce seat, brace installation of main parts, according to the monitoring element stress structure embedded, collect monitoring data, optimization design, and sum up the form a complete set of construction technology. The application of research technology, the successful solution of the cross traffic trunk line continuous beam rotation key technical problems related construction method and construction technology etc.. It has the high value in guiding the construction site. New railway engineering construction and control of Haitian-Qingdao Railway, therefore, was a huge success, Swivel Construction of a successful, rotating construction scheme satisfies the requirements of the safety of railway operation, ensure the construction quality and construction period, save the cost of the project, is a typical representative of significance.
