小断面大陡坡长斜井有轨运输施工技术研究

Research on construction technology of rail transportation for long inclined shaft with small section and steep slope

施工支洞作为特长隧洞施工过程中的物料运输通道的主要方式,往往受不良地质条件的影响,施工支洞坡度大,开挖断面小,施工难题较多。大坡度隧洞也称为斜井,受坡度较大影响,不宜采用自卸车运输,物料运输作为工程施工关键工序,运输效率及安全尤为重要。文中以内蒙古引绰济辽工程为例,对有轨运输系统进行设计和应用进行总结,其经验可为今后类似工程提供参考。

Construction branch tunnel,as the main way of material transportation in the process of construction of extra-long tunnel,is often affected by bad geological conditions,with large slope,small excavation section and many construction problems.Large slope tunnel,also known as inclined shaft,is affected by large slope,so it is not suitable to use dump truck transportation.Material transportation is a key process in engineering construction,and transportation efficiency and safety are particularly important.In this paper,the design and application of the rail transportation system are summarized with the example of the water diversion project from Chaoerhe to Liaohe in Inner Mongolia,and the experience can provide reference for similar projects in the future.
