Research on Defect Treatment of Pre-embedded Channel of Catenary in Tunnel of High-speed Railway
Pre-embedded channel fixed catenary is generally used in high-speed railway tunnel.In the construction of high-speed rail,there are a large number of defects such as embedded position errors and excessive construction errors caused by interface management and non-standard construction.In order to ensure the overall engineering quality of high-speed railway tunnels and catenary,this paper combines various channel defects in high-speed railway projects in recent years,and studies and formulates targeted remediation schemes according to the principle of avoiding abandoned projects as much as possible and maximizing the use of pre-embedded channels,such as the adaptive remediation scheme of hanger flanges and the remediation scheme of external channels,aiming to provide reference for engineering design and construction personnel.
