以哈大铁路客运专线HZQ900型架桥机低位穿越净空仅8m的公路跨铁路桥的施工转场作业为例,分析了该机穿越公路跨铁路桥的施工难点,并提出了解决方案。简要介绍HZQ900型高速铁路架桥机的主要特点和作业模式,侧重介绍该机低位转场中用到的主要部件的功用组成和技术创新点,同时阐述了低位转场作业流程。实践表明所述低位转场作业方案能够实现架桥机超低位穿越限界的要求,并具有安全、经济和高效的性能,对类似工程具有一定的指导和借鉴作用。
Take the HZQ900 bridge erecting machine of Harbin-Dalian Railway Passenger Dedicated Line as the example, the construction transitional work of the highway across the railway bridge with a clearance of only 8m is taken as an example to analyze the difficulties in the construction of the aircraft crossing the railway crossings and to put forward solutions. The main features and operating modes of HZQ900 high-speed railway bridge erecting machine are briefly introduced, focusing on the functional components and technological innovations of the main components used in the low-level transition of the aircraft. Practice shows that the low-level transition operation scheme can achieve the requirements of ultra-low crossing of the bridge erecting machine and has the characteristics of safety, economy and high efficiency, and has certain guidance and reference for similar projects.
