巷道机头硐室快速过立交掘进施工工艺应用实例

Example of the Application of the Rapid Overpass Intersection Boring Process in a Roadway Head Chamber

为了保证31119机头硐室安全过二号辅运大巷,提出了一种高效快速过立交的掘进施工工艺和支护技术措施,对比以往过立交的缺点,阐述了该施工工艺的优点。实践成功,效果显著。

In order to ensure that the 31119 head chamber can safely cross the No.2 auxiliary transportation road,this paper proposes an efficient and fast tunneling construction process and support technical measures to cross the interchange,comparing the shortcomings of the previous interchange and explaining the advantages of this construction process.The construction process was successful and effective.
