袖阀管灌浆技术在输水暗涵沉降纠偏中的应用

Application of Sleeve Valve Pipe Grouting Technologyin Settlement Correction of Water Diverting Culvert

摘要:

以袖阀管灌浆技术在南水北调济南市区段输水暗涵沉降纠偏中的应用为例,结合袖阀管注浆工艺特点,提出了分序多次循环灌浆抬升的施工工艺，并通过有限元数值模拟计算和实测数据分析，验证了袖阀管注浆在水工建筑物纠偏中的可行性和有效性，为类似工程提供了经验参考。

Abstract:

Taking the application of sleeve valve pipe grouting technology in the settlement correction of water divertingculvert in Jinan urban section of the South-to- North Water Diversion Project as an example, and combined with thecharacteristics of sleeve valve pipe grouting process, a construction process of sequential and multiple eyclic groutinglifting is proposed. Through finite element numerical simulation caleulation and measured data analysis, the feasibilityand effectiveness of sleeve valve pipe grouting in the correction of hydraulic structures are verified, providing experiencereference for similar projects,
