长大隧道洞内有轨转无轨运输方式浅谈

Discussion on Conversion of Track Transportation System into Trackless Transportation System in Long Tunnels

很多长大隧道辅助坑道的出碴方式多为有轨运输。在玉蒙铁路秀山隧道平行导坑施工中,利用正洞和平行导坑之间的横通道实现洞内有轨运输转为无轨运输,从安全、施工速度、经济效益等几个方面进行了比较,平行导坑有轨加无轨运输方式比有轨运输方式具有明显的安全性、快速性和经济性,对以后类似的工程有一定的参考价值。

Track transportation system is the dominant transportation system for many construction drifts of long tunnels.In the construction of the parallel drift of Xiushan tunnel on Yuxi-Mengzi railway,the track transportation system is converted into trackless transportation system inside the tunnel by using the cross tunnel connecting the main tunnel and the parallel drift.The conversion from the track transportation system into the trackless transportation system is presented in detail in the paper.A comparison is made between the track transportation system and the trackless transportation system in terms of safety,construction speed and economic benefit and conclusion is drawn that the track transportation system plus trackless transportation system adopted for the parallel drift has obvious superiority to the simple track transportation system.This paper can provide reference for similar projects in the future.
