秦岭隧洞下穿椒溪河段涌水处理措施探讨

Discussion on Treatment Measures of Gushing Water in Jiao-Xi River Section of Qinling Tunnel

涌水是秦岭隧洞施工中常见的地质灾害。根据引汉济渭工程秦岭隧洞下穿椒溪河段工程设计地质情况,通过对两次较大的涌水,采取确保排水能力、止浆墙封堵、帷幕灌浆处理、超前地质钻孔探水、超前小导管注浆等对策及措施,制定下一步施工的具体方案和措施,有效的预防了椒溪河隧洞施工涌水,保证了施工安全和工程的正常开展,可为秦岭隧洞施工工程涌水预防处理提供参考。

Gushing water is a common geological hazard in Qinling tunnel construction. According to the engineering design geology of the Qinling tunnel under Qinhuangdao project, through two major gushing water, the countermeasures and some measures are taken with ensuring the drainage capacity, the sealing wall sealing, the curtain grouting treatment, the advanced geological drilling water, ahead of the small catheter grouting and develops the next step in construction of specific programs and measures to effectively prevent construction of Jiaoxi River tunnel gushing water to ensure the construction safety and the normal development of the project for the Qinling tunnel construction gushing water treatment for reference.
