秦岭隧道有轨运输铁路非标准道岔设计研究

A Study of the Nonstandard Design of Switches Used in Trcak Transportion in the Construction of Qinling Tunnel

隧道施工中的窄轨运输铁路道岔,是保证行车安全和控制行车速度的关键设备,它除受本身技术条件的限制外,还受到施工条件、环境场地、通行设备等诸多因素的影响。结合秦岭隧道施工情况,对施工道岔的设计作了较详细的论述。

The switch is the key device to guarantee the operation safety and control the driving speed in narrow gauge track transportation in tunnel construction. It is not only restricted by the technical conditions of itself,but also influenced by construction circumstances,the size of construction site,traffic conditions and other factors. Combined with the construction situations of Qinling Tunnel, the design of this kind of switch is discussed in detail.
