摘要: 宁武高速公路洞宫山隧道通风竖井位于国家级风景区,且附近有一座大型水库,地表水系发达,弃碴场需新建8 km施工便道。在工期、地质条件允许的前提下,采用了“先导井打通后扩挖法开挖+滑模施工衬砌及不对称中隔墙”节能降耗施工新技术。此技术的应用最大限度地减少了资源投入,降低了竖井施工对风景区的环境污染,较采用传统方法缩短工期50%,降低劳动强度60%左右,节约能源型消耗材料60%以上,取得了良好的经济、社会和环境效益。

Abstract: The ventilation shafts of Donggongshan tunnel on NingdeWuyishan highway are located in national beauty spot and there is a largescale reservoir near the ventilation shafts. There are strict environmental requirements for the sinking of the ventilation shafts. Energysaving and consumptionreducing technologies, including guiding hole drilling, enlarging excavation, lining and asymmetric separation wall installing by means of slip formwork, are used. In the end, the influence on the environment is minimized, the construction duration is shortened by 50%, the labor intensity is reduced by 60%, and the consumption of the energy materials is reduced by 60%. Good economic, social and environmental benefits have been achieved.
