目前,我们已经建成和在运营多条高速铁路,我国高速铁路建设技术经过近十年的发展,技术日臻成熟,这些技术的成熟和不断进步与铁路建设施工机械化水平大幅度提高有着密切的关系。如何看待我国铁路建设、特别是无砟轨道建设机械化发展,对于我国工程机械的研制和施工企业的设备管理有着重要意义。无砟轨道施工机械化发展的主要特点构件预制的普遍使用带动了工厂化作业无砟轨道以“结构稳定,少维修”等特点而著称于世。由于工期和质量的要求,结构物大多采用了预制技术。如武广客专、郑西客专的双块式轨枕,即为预制构件,现场进行安装调整后浇注混凝
At present, we have built and operated a number of high-speed railways. After nearly a decade of development, the technology of high-speed railway construction has matured. The maturity and continuous improvement of these technologies are closely linked with the substantial increase in the mechanization of railway construction. How to treat the railway construction in our country, especially the development of mechanization of ballastless track, is of great significance to the research and construction of construction machinery and equipment management of construction enterprises in our country. The main features of mechanized development of ballastless track construction The widespread use of prefabrication of components has led to the ballastless track of industrialized operation known as “stable structure, less maintenance” and other features. Due to the duration and quality requirements, most of the structures use prefabricated technology. Such as Wuhan-Guangzhou Passenger, Zheng West Passenger dual-block sleeper, which is prefabricated components, on-site installation and adjustment pouring coagulation
