王刚村铁路隧道喇叭口段施工技术

Construction technology of bell-mouth section of Wanggangcun railway tunnel

随着铁道建设的快速发展,铁路隧道喇叭口段施工日益增多,成为制约隧道施工的重点和难点。本文结合王刚村铁路隧道喇叭口段施工的成功实践,详细阐述了隧道喇叭口段的施工技术,包括大跨衬砌段施工方法、双拱衬砌段施工方法、加强衬砌段施工以及双线段仰拱施工,为解决铁路双线段仰拱施工问题提供参考。

With the rapid development of railway construction,the construction of bell-mouth section of railway tunnel is increasing day by day,which has become the key and difficult point of tunnel construction.Combined with the successful construction of bell-mouth section of Wanggangcun railway tunnel,the construction methods of long-span lining section,double-arched lining section,strengthened lining section,and inverted arch of double-lined section were elaborated in detail,which provided technical reference for solving the inverted arch construction problems of double-lined railway.
