Installation and Precise Calibration of Ballastless Track Slab Formwork for High-Speed Railways
ZHAO Baocheng
Abstract：This paper proposes a novel approach to the installation and fine adjustment of ballastless track slab formwork for high-speed railways.The proposed methodology addresses the challenges encountered during the installation and construction of high-speed railway ballastless track formwork.The establishment of a CP Ⅲ control network,along with the measurement process and the completion of the installation,is paramount during the implementation of the ballastless track slab formwork for high-speed railways.Prior to the initiation of the installation process,it is essential to meticulously inspect the template and formulate a construction process that encompasses the installation of track plates,base plates,and steel rails.Once the preparatory work has been completed,the template is installed.Subsequently,the concrete pouring construction phase is initiated,and the formwork is removed at an appropriate juncture.A precise adjustment sequence is designed based on the actual construction situation in order to achieve the necessary refinements.The experimental results demonstrate that the proposed technology is capable of effectively predicting and adjusting various cross-sectional information under different states,thereby ensuring the safety of the installation and construction of ballastless track slab templates for high-speed railways.
