摘要
结合承朝高速公路长逢沟隧道洞口浅埋段的施工情况,介绍了长大管棚大型机械化施工的施工工艺、技术要点和控制难点,对施工中常见的导向管定位不准、钻孔弯曲侵限等问题进行分析并提出解决办法,为管棚施工质量控制提供了一定的参考。
Combined with the construction of the shallowly buried section at Changfenggou Tunnel entrance in Chengchao Expressway, the construction process, key points of the technology and control difficulties of biglong pipe-roof construction are introduced. Some common problems including guiding pipe position inaccuracy, dr bending are analyzed, and the solutions are also put forward, which provide reference for the quality contro pipe-roof construction ng of
