本文结合上旧庄隧道施工,对该段采用的WSS注浆技术,从技术原理、施工流程、要点等方面作介绍。施工实践表明,该技术在隧道穿越富水砂层段,堵水和砂层固化效果明显,对同类地质条件下的地下工程施工具有指导和借鉴意义。
Combined with the construction of Shangzhuangzhuang tunnel, this paper introduces the WSS grouting technology adopted in this section from the aspects of technical principle, construction flow and important points. The construction practice shows that the technology has obvious effect of blocking water and sand solidification in the tunnel through the section of water-rich sandstone and is of guidance and reference for underground engineering construction under similar geological conditions.
