小江口隧道出口施工方案

Construction Plan of Xiaojiangkou Tunnel Exportation

为保证小江口隧道双向施工,以确保余凯高速公路项目顺利通车,结合小江口隧道的地质条件及出口段的地形条件,拟定了3个施工方案进行综合比较,最终推荐利用桥梁进洞的施工方案,以保证隧道及整个项目的施工工期。

In order to ensure bidirectional construction of the xiaojiangkou tunnel and guarantee yukai-highway project to be open to traffic smoothly,three construction plans are drawn up combining the geological condition of Xiaojiangkou tunnel and the topographical condition of the export section.By comparing these plans,the tunnel-entering construction plan using bridge is recommended in the end which can guarantee safety of the tunnel and the construction period of the project.
