Research on the Application of Measurement Technology in the Whole Process of Remediation of Geometric Alignment Defects on Subway Business Lines
After a long period of operation,subway lines have suffered from various degrees of damage to their track geometry.In order to effectively ensure the safe and stable operation of urban rails,special recti-fication of geometric line diseases is urgently needed.On the basis of independent spatial two-level control,high-precision measurement methods are used to collect on-site data,and a three-dimensional geometric line fitting system is developed to provide measurement and construction guidance for the remediation of geometric line diseases on subway business lines.The results show that this set of measurement technology meets the needs of on-site construction,achieves full process control,promotes the digital construction of maintenance construction,and reduces the workload by 30％compared with existing technology.
