盾构穿越大堤防渗处理加固施工与效果

The shield driving crosses the big dike seep handle and reinforce construction and effect

结合具体工程实例,提出了盾构隧道施工穿越防洪大堤的防渗加固处理方案,详细介绍了隧道穿越段防渗处理施工工艺,得出了该工程加固强度和抗渗指标满足设计要求的结论,指出选用搅拌桩、注浆和隧道内管片二次注浆相结合的措施是一种有效的加固处理方案。

The paper combines concrete engineering, puts forward shield driving tunnel construction crossing flood control big reinforcing han- dling project, detailedly introduces tunnel crossing first segment defending the seep handle construction craft, having to out that engineering reinforce the strength with the anti-seep index sign satisfies to design request, points out to choose to use the pipe, grouting and tube slice inside the tunnel combining together is a kind of to reinforce handle effectively project.
