某专用铁路沉陷区路基整治技术研究

Study on subgrade treatmenttechnology in subsidence area of a special railway

随着煤矿工作面的不断开采,越来越多的矿区专用线受到影响,对沉陷区铁路的治理是一项工作量大且时常要处理的一项工程,简述了沉陷区铁路预治理技术,对抬道厚度、煤矸石抬高帮宽路基、碎石盲沟的设置、施工便道的设置、煤矸石填料的技术要求、环境保护与水土保持措施以及施工注意事项等进行了探讨,对其中的一些技术参数进行了分析计算。

With the continuous mining on the working face in coal mine,more and more lines dedicated for the mining area are affected,and therefore the treatment of railways in subsidence area is a project that has heavy workload and requires frequent handling;the article briefly describes the technologies of pre-treatment of railways in subsidence area,probes into the thickness of lift line,wide subgrade on coal gangue lift side,setting of gravel blind ditch,setting of construction access road,technical requirements for coal gangue filler,environmental protection and soil and water conservation measures,precautions for construction,etc.,and analyzes and calculates some technical parameters.
