Process and Simulation Analysis of Overhead Contact Line Adjusting Pillar Set up and Hard Beam Erection
Over contact line is critical to the railway system,providing power supply and train support.Catenary includes many different types of pillar and beams,of which adjusting pillar and hard beams play important roles in ensuring the stability and safety of the catenary.Modifying the hard beams of the existing catenary pillar before the section shield tunnelling includes the erection of new hard beams and the removal of the existing hard beams.The influence range of shield construction on the railway was determined using the data and numerical simulation analysis,and the corresponding suggestions were given.Finally,according to the actual situation,the modification plan of the hard beam was adjusted,and the direction of pulling out value and the specific operation method were determined.
